           (4) A temporary fixed broadband station may use any available broadband channel on a secondary
               basis, except that operation of temporary fixed broadband stations is not allowed within 56.3 km (35
               miles) of Canada.

           (5)

                 (i)   A point-to-point EBS station on the E and F-channel frequencies, may be involuntarily displaced
                       by a BRS applicant or licensee, provided that suitable alternative spectrum is available and that
                       the BRS entity bears the expenses of the migration. Suitability of spectrum will be determined
                       on a case-by-base basis; at a minimum, the alternative spectrum must be licensable by
                       broadband operators on a primary basis (although it need not be specifically allocated to the
                       broadband service), and must provide a signal that is equivalent to the prior signal in picture
                       quality and reliability, unless the broadband licensee will accept an inferior signal. Potential
                       expansion of the BRS licensee may be considered in determining whether alternative available
                       spectrum is suitable.

                 (ii) If suitable alternative spectrum is located pursuant to paragraph (h)(6)(i) of this section, the
                      initiating party must prepare and file the appropriate application for the new spectrum, and
                      must simultaneously serve a copy of the application on the EBS licensee to be moved. The
                      initiating party will be responsible for all costs connected with the migration, including
                      purchasing, testing and installing new equipment, labor costs, reconfiguration of existing
                      equipment, administrative costs, legal and engineering expenses necessary to prepare and file
                      the migration application, and other reasonable documented costs. The initiating party must
                      secure a bond or establish an escrow account to cover reasonable incremental increase in
                      ongoing expenses that may fall upon the migrated licensee. The bond or escrow account
                      should also account for the possibility that the initiating party subsequently becomes bankrupt.
                      If it becomes necessary for the Commission to assess the sufficiency of a bond or escrow
                      amount, it will take into account such factors as projected incremental increase in electricity or
                      maintenance expenses, or relocation expenses, as relevant in each case.

                 (iii) The EBS licensee to be moved will have a 60-day period in which to oppose the involuntary
                       migration. The broadband party should state its opposition to the migration with specificity,
                       including engineering and other challenges, and a comparison of the present site and the
                       proposed new site. If involuntary migration is granted, the new facilities must be operational
                       before the initiating party will be permitted to begin its new or modified operations. The
                       migration must not disrupt the broadband licensee's provision of service, and the broadband
                       licensee has the right to inspect the construction or installation work.

               MHz and 805–806 MHz bands are based on Major Economic Areas (MEAs), as defined in
               paragraphs (a)(1) and (a)(2) of this section.

           (2) Service areas for Block C in the 746–757 MHz and 776–787 MHz bands are based on Regional
               Economic Area Groupings (REAGs) as defined by paragraph (a) of this section. In the event that no
               licenses with respect to service areas for Block C in the 746–757 MHz and 776–787 MHz bands are
               assigned based on the results of the first auction in which such licenses are offered because the
               auction results do not satisfy the applicable reserve price, then service areas for the spectrum at
               746–757 MHz and 776–787 MHz will instead be available for assignment as follows:

                 (i)   Service areas for Block C1 in the 746–752 MHz and 776–782 MHz bands are based on

                 (ii) Service areas for Block C2 in the 752–757 MHz and 782–787 MHz bands are based on
                      Regional Economic Area Groupings (REAGs) as defined by paragraph (a) of this section.

     (c) 698–746 MHz band. WCS service areas for the 698–746 MHz band are as follows:

           (1) Service areas for Block A in the 698–704 MHz and 728–734 MHz bands and Block E in the 722–728
               MHz band are based on Economic Areas (EAs) as defined in paragraph (a) of this section.

           (2) Service areas for Block B in the 704–710 MHz and 734–740 MHz bands and Block C in the 710–716
               MHz and 740–746 MHz bands are based on cellular markets comprising Metropolitan Statistical
               Areas (MSAs) and Rural Service Areas (RSAs) as defined by Public Notice Report No. CL–92–40
               “Common Carrier Public Mobile Services Information, Cellular MSA/RSA Markets and Counties,”
               dated January 24, 1992, DA 92–109, 7 FCC Rcd 742 (1992), with the following modifications:

                 (i)   The service areas of cellular markets that border the U.S. coastline of the Gulf of Mexico extend
                       12 nautical miles from the U.S. Gulf coastline.

                 (ii) The service area of cellular market 306 that comprises the water area of the Gulf of Mexico
                      extends from 12 nautical miles off the U.S. Gulf coast outward into the Gulf.

           (3) Service areas for Block D in the 716–722 MHz band are based on Economic Area Groupings (EAGs)
               as defined by the Federal Communications Commission. See 62 FR 15978 (April 3, 1997) extended
               with the Gulf of Mexico. See also paragraphs (a)(1) and (2) of this section and 62 FR 9636 (March 3,
               1997), in which the Commission created an additional four economic area-like areas for a total of

Subpart B—Applications and Licenses
§ 27.10 Regulatory status.
The following rules apply concerning the regulatory status in the frequency bands specified in § 27.5.

     (a) Single authorization. Authorization will be granted to provide any or a combination of the following
         services in a single license: common carrier, non-common carrier, private internal communications, and
         broadcast services. A licensee may render any kind of communications service consistent with the
         regulatory status in its license and with the Commission's rules applicable to that service. An applicant or
         licensee may submit a petition at any time requesting clarification of the regulatory status for which
         authorization is required to provide a specific communications service.

     (b) Designation of regulatory status in initial application. An applicant shall specify in its initial application if it
         is requesting authorization to provide common carrier, non-common carrier, private internal
         communications, or broadcast services, or a combination thereof.

     (c) Amendment of pending applications. The following rules apply to amendments of a pending application.

           (1) Any pending application may be amended to:

                 (i)   Change the carrier regulatory status requested, or

                (ii) Add to the pending request in order to obtain common carrier, non-common carrier, private
                     internal communications, or broadcast services status, or a combination thereof, in a single
                     license.

           (2) Amendments to change, or add to, the carrier regulatory status in a pending application are minor
               amendments filed under § 1.927 of this chapter.

     (d) Modification of license. The following rules apply to amendments of a license.

           (1) A licensee may modify a license to:

                 (i)   Change the regulatory status authorized, or

                (ii) Add to the status authorized in order to obtain a combination of services of different regulatory
                     status in a single license.

           (2) Applications to change, or add to, the carrier status in a license are modifications not requiring prior
               Commission authorization. The licensee must notify the Commission within 30 days of the change.
               If the change results in the discontinuance, reduction, or impairment of an existing service, the
               licensee is subject to the provisions of § 27.66.

§ 27.14 Construction requirements.
     (a) AWS and WCS licensees, with the exception of WCS licensees holding authorizations for the 600 MHz
         band, Block A in the 698–704 MHz and 728–734 MHz bands, Block B in the 704–710 MHz and 734–740

         bands, Block A in the 2305–2310 MHz and 2350–2355 MHz bands, Block B in the 2310–2315 MHz and
         2355–2360 MHz bands, Block C in the 2315–2320 MHz band, Block D in the 2345–2350 MHz band, in the
         3450–3550 MHz band, and in the 3700–3980 MHz band, and with the exception of licensees holding AWS
         authorizations in the 1915–1920 MHz and 1995–2000 MHz bands, the 2000–2020 MHz and 2180–2200
         MHz bands, or 1695–1710 MHz, 1755–1780 MHz and 2155–2180 MHz bands, must, as a performance
         requirement, make a showing of “substantial service” in their license area within the prescribed license
         term set forth in § 27.13. “Substantial service” is defined as service which is sound, favorable and
         substantially above a level of mediocre service which just might minimally warrant renewal. Failure by any
         licensee to meet this requirement will result in forfeiture of the license and the licensee will be ineligible to
         regain it.

          authorizations no later than June 13, 2013 (or within four years of initial license grant if the initial
          authorization in a market is granted after June 13, 2009), and shall provide such service over at least 70
          percent of the geographic area of each of these authorizations by the end of the license term. In applying
          these geographic benchmarks, licensees are not required to include land owned or administered by
          government as a part of the relevant service area. Licensees may count covered government land for
          purposes of meeting their geographic construction benchmark, but are required to add the covered
          government land to the total geographic area used for measurement purposes. Licensees are required to
          include those populated lands held by tribal governments and those held by the Federal Government in
          trust or for the benefit of a recognized tribe.

           (1) If an EA or CMA licensee holding an authorization in these particular blocks fails to provide signal
               coverage and offer service over at least 35 percent of the geographic area of its license
               authorization by no later than June 13, 2013 (or within four years of initial license grant, if the initial
               authorization in a market is granted after June 13, 2009), the term of that license authorization will
               be reduced by two years and such licensee may be subject to enforcement action, including
               forfeitures. In addition, an EA or CMA licensee that provides signal coverage and offers service at a
               level that is below this interim benchmark may lose authority to operate in part of the remaining
               unserved areas of the license.

           (2) If any such EA or CMA licensee fails to provide signal coverage and offer service to at least 70
               percent of the geographic area of its license authorization by the end of the license term, that
               licensee's authorization will terminate automatically without Commission action for those
               geographic portions of its license in which the licensee is not providing service, and those unserved
               areas will become available for reassignment by the Commission. Such licensee may also be subject
               to enforcement action, including forfeitures. In addition, an EA or CMA licensee that provides signal
               coverage and offers service at a level that is below this end-of-term benchmark may be subject to
               license termination. In the event that a licensee's authority to operate in a license area terminates
               automatically without Commission action, such areas will become available for reassignment
               pursuant to the procedures in paragraph (j) of this section.

           (3) For licenses under paragraph (g) of this section, the geographic service area to be made available for
               reassignment must include a contiguous area of at least 130 square kilometers (50 square miles),
               and areas smaller than a contiguous area of at least 130 square kilometers (50 square miles) will
               not be deemed unserved.

     (h) WCS licensees holding REAG authorizations for Block C in the 746–757 MHz and 776–787 MHz bands or
         REAG authorizations for Block C2 in the 752–757 MHz and 782–787 MHz bands shall provide signal
         coverage and offer service over at least 40 percent of the population in each EA comprising the REAG
         license area no later than June 13, 2013 (or within four years of initial license grant, if the initial
         authorization in a market is granted after June 13, 2009), and shall provide such service over at least 75
         percent of the population of each of these EAs by the end of the license term. For purposes of compliance
         with this requirement, licensees should determine population based on the most recently available U.S.

               that a licensee's authority to operate in a license area terminates automatically without Commission
               action, such areas will become available for reassignment pursuant to the procedures in paragraph

               within that EA.

           (3) For licenses under paragraph (h), the geographic service area to be made available for reassignment
               must include a contiguous area of at least 130 square kilometers (50 square miles), and areas
               smaller than a contiguous area of at least 130 square kilometers (50 square miles) will not be
               deemed unserved.

     (i)   WCS licensees holding EA authorizations for Block A in the 698–704 MHz and 728–734 MHz bands,
           cellular market authorizations for Block B in the 704–710 MHz and 734–740 MHz bands, or EA
           authorizations for Block E in the 722–728 MHz band, if the results of the first auction in which licenses for

           block, as well as EA authorizations for Block C1 in the 746–752 MHz and 776–782 MHz bands, are
           subject to the following:

           (1) If a licensee holding a cellular market area or EA authorization subject to this paragraph (i) fails to
               provide signal coverage and offer service over at least 40 percent of the population in its license area
               by no later than June 13, 2013 (or within four years of initial license grant, if the initial authorization
               in a market is granted after June 13, 2009), the term of that license authorization will be reduced by
               two years and such licensee may be subject to enforcement action, including forfeitures. In addition,
               such licensee that provides signal coverage and offers service at a level that is below this interim
               benchmark may lose authority to operate in part of the remaining unserved areas of the license. For
               purposes of compliance with this requirement, licensees should determine population based on the
               most recently available U.S. Census Data.

           (2) If a licensee holding a cellular market area or EA authorization subject to this paragraph (i) fails to
               provide signal coverage and offer service over at least 75 percent of the population in its license area
               by the end of the license term, that licensee's authorization will terminate automatically without
               Commission action for those geographic portions of its license in which the licensee is not providing
               service, and those unserved areas will become available for reassignment by the Commission. Such
               licensee may also be subject to enforcement action, including forfeitures. In the event that a

           (3) For licenses under paragraph (i), the geographic service area to be made available for reassignment
               must include a contiguous area of at least 130 square kilometers (50 square miles), and areas
               smaller than a contiguous area of at least 130 square kilometers (50 square miles) will not be

     (j)   In the event that a licensee's authority to operate in a license area terminates automatically under
           paragraphs (g), (h), or (i) of this section, such areas will become available for reassignment pursuant to
           the following procedures:

           (1) The Wireless Telecommunications Bureau is delegated authority to announce by public notice that
               these license areas will be made available and establish a 30-day window during which third parties
               may file license applications to serve these areas. During this 30-day period, licensees that had their
               authority to operate terminate automatically for unserved areas may not file applications to provide
               service to these areas. Applications filed by third parties that propose areas overlapping with other
               applications will be deemed mutually exclusive, and will be resolved through an auction. The
               Wireless Telecommunications Bureau, by public notice, may specify a limited period before the filing
               of short-form applications (FCC Form 175) during which applicants may enter into a settlement to
               resolve their mutual exclusivity, subject to the provisions of § 1.935 of this chapter.

           (2) Following this 30-day period, the original licensee and third parties can file license applications for
               remaining unserved areas where licenses have not been issued or for which there are no pending
               applications. If the original licensee or a third party files an application, that application will be
               placed on public notice for 30 days. If no mutually exclusive application is filed, the application will
               be granted, provided that a grant is found to be in the public interest. If a mutually exclusive
               application is filed, it will be resolved through an auction. The Wireless Telecommunications Bureau,
               by public notice, may specify a limited period before the filing of short-form applications (FCC Form
               175) during which applicants may enter into a settlement to resolve their mutual exclusivity, subject
               to the provisions of § 1.935 of this chapter.

           (3) The licensee will have one year from the date the new license is issued to complete its construction
               and provide signal coverage and offer service over 100 percent of the geographic area of the new
               license area. If the licensee fails to meet this construction requirement, its license will automatically
               terminate without Commission action and it will not be eligible to apply to provide service to this
               area at any future date.

     (k) Licensees holding WCS or AWS authorizations in the spectrum blocks enumerated in paragraphs (g), (h),
         (i), (q), (r), (s), (t), (v), and (w) of this section, including any licensee that obtained its license pursuant to
         the procedures set forth in paragraph (j) of this section, shall demonstrate compliance with performance
         requirements by filing a construction notification with the Commission, within 15 days of the expiration of
         the applicable benchmark, in accordance with the provisions set forth in § 1.946(d) of this chapter. The
         licensee must certify whether it has met the applicable performance requirements. The licensee must file
         a description and certification of the areas for which it is providing service. The construction notifications
         must include electronic coverage maps, supporting technical documentation and any other information
         as the Wireless Telecommunications Bureau may prescribe by public notice.

     (l)   WCS licensees holding authorizations in the spectrum blocks enumerated in paragraphs (g), (h), or (i) of
           this section, excluding any licensee that obtained its license pursuant to the procedures set forth in
           subsection (j) of this section, shall file reports with the Commission that provide the Commission, at a
           minimum, with information concerning the status of their efforts to meet the performance requirements
           applicable to their authorizations in such spectrum blocks and the manner in which that spectrum is
           being utilized. The information to be reported will include the date the license term commenced, a

           description of the steps the licensee has taken toward meeting its construction obligations in a timely
           manner, including the technology or technologies and service(s) being provided, and the areas within the
           license area in which those services are available. Each of these licensees shall file its first report with the
           Commission no later than June 13, 2011 and no sooner than 30 days prior to this date. Each licensee that
           meets its interim benchmarks shall file a second report with the Commission no later than June 13, 2016
           and no sooner than 30 days prior to this date. Each licensee that does not meet its interim benchmark
           shall file this second report no later than on June 13, 2015 and no sooner than 30 days prior to this date.

    (m)–(n) [Reserved]

     (o) With respect to initial BRS licenses issued on or after November 6, 2009, the licensee must make a
         showing of substantial service within four years from the date of issue of the license. With respect to EBS
         licenses issued after October 25, 2019, the licensee must comply with paragraph (u) of this section.
         “Substantial service” is defined as service which is sound, favorable, and substantially above a level of
         mediocre service which just might minimally warrant renewal. Substantial service for BRS and EBS
         licensees is satisfied if a licensee meets the requirements of paragraph (o)(1), (2), or (3) of this section. If
         a licensee has not met the requirements of paragraph (o)(1), (2), or (3) of this section, then demonstration
         of substantial service shall proceed on a case-by-case basis. Except as provided in paragraphs (o)(4) and
         (5) of this section, all substantial service determinations will be made on a license-by-license basis.
         Failure by any licensee to demonstrate substantial service will result in forfeiture of the license and the
         licensee will be ineligible to regain it.

           (1) A BRS or EBS licensee has provided “substantial service” by:

                 (i)   Constructing six permanent links per one million people for licensees providing fixed point-to-
                       point services;

                 (ii) Providing coverage of at least 30 percent of the population of the licensed area for licensees
                      providing mobile services or fixed point-to-multipoint services;

                (iii) Providing service to “rural areas” (a county (or equivalent) with a population density of 100
                      persons per square mile or less, based upon the most recently available Census data) and
                      areas with limited access to telecommunications services:

                       (A) For mobile service, where coverage is provided to at least 75% of the geographic area of at
                           least 30% of the rural areas within its service area; or

                       (B) for fixed service, where the BRS or EBS licensee has constructed at least one end of a
                           permanent link in at least 30% of the rural areas within its licensed area.

                (iv) Providing specialized or technologically sophisticated service that does not require a high level
                     of coverage to benefit consumers; or

                 (v) Providing service to niche markets or areas outside the areas served by other licensees.

           (2) An EBS license initially issued prior to October 25, 2019 has provided “substantial service” when:

                 (i)   The EBS licensee is using its spectrum (or spectrum to which the EBS licensee's educational
                       services are shifted) to provide educational services within the EBS licensee's GSA;

                 (ii) the EBS licensee's license is actually being used to serve the educational mission of one or
                      more accredited public or private schools, colleges or universities providing formal educational
                      and cultural development to enrolled students; or

Miscellaneous Wireless Communications Services

                (iii) The level of service provided by the EBS licensee meets or exceeds the minimum usage
                      requirements specified in § 27.1214 contained in the edition of 47 CFR parts 20 through 39,
                      revised as of October 1, 2017.

           (3) An EBS or BRS licensee may be deemed to provide substantial service through a leasing
               arrangement if the lessee is providing substantial service under paragraph (o)(1) of this section.

           (4) If the GSA of a licensee is less than 1924 square miles in size, and there is an overlapping co-channel
               station licensed or leased by the licensee or its affiliate, substantial service may be demonstrated by
               meeting the requirements of paragraph (o)(1) or (o)(2) of this section with respect to the combined
               GSAs of both stations.

           (5) If the GSA of a BTA authorization holder, is less than one-half of the area within the BTA for every
               BRS channel, substantial service may be demonstrated for the licenses in question by meeting the
               requirements of paragraph (o)(1) or (o)(2) of this section with respect to the combined GSAs of the
               BTA authorization holder, together with any incumbent authorizations licensed or leased by the
               licensee or its affiliates.

     (p) This section enumerates performance requirements for licensees holding authorizations for Block A in the
         2305–2310 MHz and 2350–2355 MHz bands, Block B in the 2310–2315 MHz and 2355–2360 MHz
         bands, Block C in the 2315–2320 MHz band, and Block D in the 2345–2350 MHz band.

           (1) For mobile and point-to-multipoint systems in Blocks A and B, and point-to-multipoint systems in
               Blocks C and D, a licensee must provide reliable signal coverage and offer service to at least 40
               percent of the license area's population by March 13, 2017, and to at least 75 percent of the license
               area's population by September 13, 2019. If, when filing the construction notification required under
               § 1.946(d) of this chapter, a WCS licensee demonstrates that 25 percent or more of the license
               area's population for Block A, B or D is within a coordination zone as defined by § 27.73(a) of the
               rules, the foregoing population benchmarks are reduced to 25 and 50 percent, respectively. The
               percentage of a license area's population within a coordination zone equals the sum of the Census
               Block Centroid Populations within the area, divided by the license area's total population.

           (2) For point-to-point fixed systems, except those deployed in the Gulf of Mexico license area, a licensee
               must construct and operate a minimum of 15 point-to-point links per million persons (one link per
               67,000 persons) in a license area by March 13, 2017, and 30 point-to-point links per million persons
               (one link per 33,500 persons) in a licensed area by September 13, 2019. The exact link requirement is
               calculated by dividing a license area's total population by 67,000 and 33,500 for the respective
               milestones, and then rounding upwards to the next whole number. For a link to be counted towards
               these benchmarks, both of its endpoints must be located in the license area. If only one endpoint of
               a link is located in a license area, it can be counted as a one- half link towards the benchmarks.

           (3) For point-to-point fixed systems deployed on any spectrum block in the Gulf of Mexico license area, a
               licensee must construct and operate a minimum of 15 point-to-point links by March 13, 2017, and a
               minimum of 15 point-to-point links by September 13, 2019.

           (4) Under paragraph (p)(2) and (p)(3) of this section, each fixed link must provide a minimum bit rate, in
               bits per second, equal to or greater than the bandwidth specified by the emission designator in Hertz
               (e.g., equipment transmitting at a 5 Mb/s rate must not require a bandwidth of greater than 5 MHz).

           (5) If an initial authorization for a license area is granted after March 13, 2013, then the applicable
               benchmarks in paragraphs (p)(1), (2) and (3) of this section must be met within 48 and 78 months,
               respectively, of the initial authorization grant date.

Miscellaneous Wireless Communications Services

           (6) Licensees must use the most recently available U.S. Census Data at the time of measurement to
               meet these performance requirements.

           (7) Licensees must certify compliance with the applicable performance requirements by filing a
               construction notification with the Commission, within 15 days of the expiration of the relevant
               performance milestone, pursuant to § 1.946(d) of this chapter. Each construction notification must
               include electronic coverage maps, supporting technical documentation, and any other information as
               the Wireless Telecommunications Bureau may prescribe by public notice. Electronic coverage maps
               must accurately depict the boundaries of each license area (Regional Economic Area Grouping,
               REAG, or Major Economic Area, MEA) in the licensee's service territory. Further, REAG maps must
               depict MEA boundaries and MEA maps must depict Economic Area boundaries. If a licensee does
               not provide reliable signal coverage to an entire license area, its map must accurately depict the
               boundaries of the area or areas within each license area not being served. Each licensee also must
               file supporting documentation certifying the type of service it is providing for each REAG or MEA
               within its service territory and the type of technology used to provide such service. Supporting
               documentation must include the assumptions used to create the coverage maps, including the
               propagation model and the signal strength necessary to provide reliable service with the licensee's
               technology.

           (8) If a licensee fails to meet any applicable performance requirement, its authorization will terminate
               automatically without further Commission action as of the applicable performance milestone and
               the licensee will be ineligible to regain it.

     (q) The following provisions apply to any licensee holding an AWS authorization in the 2000–2020 MHz and
         2180–2200 MHz bands (an “AWS–4 licensee”):

           (1) An AWS–4 licensee shall provide terrestrial signal coverage and offer terrestrial service within four
               (4) years from the date of the license to at least forty (40) percent of the total population in the
               aggregate service areas that it has licensed in the 2000–2020 MHz and 2180–2200 MHz bands
               (“AWS–4 Interim Buildout Requirement”). For purposes of this subpart, a licensee's total population
               shall be calculated by summing the population of each license area that a licensee holds in the
               2000–2020 MHz and 2180–2200 MHz bands; and

           (2) An AWS–4 licensee shall provide terrestrial signal coverage and offer terrestrial service within seven
               (7) years from the date of the license to at least seventy (70) percent of the population in each of its
               license areas in the 2000–2020 MHz and 2180–2200 MHz bands (“AWS–4 Final Buildout
               Requirement”).

           (3) If any AWS–4 licensee fails to establish that it meets the AWS–4 Interim Buildout Requirement, the
               AWS–4 Final Buildout requirement shall be accelerated by one year from (seven to six years).

           (4) If any AWS–4 licensee fails to establish that it meets the AWS–4 Final Buildout Requirement in any
               of its license areas in the 2000–2020 MHz and 2180–2200 MHz bands, its authorization for each
               license area in which it fails to meet the requirement shall terminate automatically without
               Commission action. To the extent that the AWS–4 licensee also holds the 2 GHz MSS rights for the
               affected license area, failure to meet the AWS–4 Final Buildout Requirement in an EA shall also
               result in the MSS protection rule in § 27.1136 no longer applying in that license area.

           (5) To demonstrate compliance with these performance requirements, licensees shall use the most
               recently available U.S. Census Data at the time of measurement and shall base their measurements
               of population served on areas no larger than the Census Tract level. The population within a specific
               Census Tract (or other acceptable identifier) will only be deemed served by the licensee if it provides

                signal coverage to and offers service within the specific Census Tract (or other acceptable
                identifier). To the extent the Census Tract (or other acceptable identifier) extends beyond the
                boundaries of a license area, a licensee with authorizations for such areas may only include the
                population within the Census Tract (or other acceptable identifier) towards meeting the performance
                requirement of a single, individual license.

           (6) Failure by any AWS–4 licensee to meet the AWS–4 Final Buildout Requirement in paragraph (q)(4) of
               this section will result in forfeiture of the license and the licensee will be ineligible to regain it.

     (r) The following provisions apply to any licensee holding an AWS authorization in the 1915–1920 MHz and
         1995–2000 MHz bands:

           (1) A licensee shall provide signal coverage and offer service within four (4) years from the date of the
               initial license to at least forty (40) percent of the population in each of its licensed areas (“Interim
               Buildout Requirement”).

           (2) A licensee shall provide signal coverage and offer service within ten (10) years from the date of the
               initial license to at least seventy-five (75) percent of the population in each of its licensed areas
               (“Final Buildout Requirement”).

           (3) If a licensee fails to establish that it meets the Interim Buildout Requirement for a particular licensed
               area, then the Final Buildout Requirement (in this paragraph (r)) and the license term (as set forth in
               § 27.13(j)) for each license area in which it fails to meet the Interim Buildout Requirement shall be
               accelerated by two years (from ten to eight years).

           (4) If a licensee fails to establish that it meets the Final Buildout Requirement for a particular licensed
               area, its authorization for each license area in which it fails to meet the Final Buildout Requirement
               shall terminate automatically without Commission action and the licensee will be ineligible to regain
               it if the Commission makes the license available at a later date.

           (5) To demonstrate compliance with these performance requirements, licensees shall use the most
               recently available U.S. Census Data at the time of measurement and shall base their measurements
               of population served on areas no larger than the Census Tract level. The population within a specific
               Census Tract (or other acceptable identifier) will only be deemed served by the licensee if it provides
               signal coverage to and offers service within the specific Census Tract (or other acceptable
               identifier). To the extent the Census Tract (or other acceptable identifier) extends beyond the
               boundaries of a license area, a licensee with authorizations for such areas may only include the
               population within the Census Tract (or other acceptable identifier) towards meeting the performance
               requirement of a single, individual license.

     (s) The following provisions apply to any licensee holding an AWS authorization in the 1695–1710 MHz,
         1755–1780 MHz, and 2155–2180 MHz bands:

           (1) A licensee shall provide reliable signal coverage and offer service within six (6) years from the date
               of the initial license to at least forty (40) percent of the population in each of its licensed areas
               (“Interim Buildout Requirement”).

           (2) A licensee shall provide reliable signal coverage and offer service within twelve (12) years from the
               date of the initial license to at least seventy-five (75) percent of the population in each of its licensed
               areas (“Final Buildout Requirement”).

               shall be accelerated by two (2) years (from twelve (12) to ten (10) years).

           (4) If a licensee fails to establish that it meets the Final Buildout Requirement for a particular licensed
               area, its authorization for each license area in which it fails to meet the Final Buildout Requirement
               shall terminate automatically without Commission action and the licensee will be ineligible to regain
               it if the Commission makes the license available at a later date.

           (5) To demonstrate compliance with these performance requirements, licensees shall use the most
               recently available U.S. Census Data at the time of measurement and shall base their measurements
               of population served on areas no larger than the Census Tract level. The population within a specific
               Census Tract (or other acceptable identifier) will be deemed served by the licensee only if it provides
               signal coverage to and offers service within the specific Census Tract (or other acceptable
               identifier). To the extent the Census Tract (or other acceptable identifier) extends beyond the
               boundaries of a license area, a licensee with authorizations for such areas may include only the
               population within the Census Tract (or other acceptable identifier) towards meeting the performance
               requirement of a single, individual license. For the Gulf of Mexico license area, the licensee shall
               demonstrate compliance with these performance requirements, using off-shore platforms, including
               production, manifold, compression, pumping and valving platforms as a proxy for population in the
               Gulf of Mexico.

     (t) The following provisions apply to any licensee holding an authorization in the 600 MHz band:

           (1) A licensee shall provide reliable signal coverage and offer service within six (6) years from the date
               of the initial license to at least forty (40) percent of the population in each of its license areas
               (“Interim Buildout Requirement”).

           (2) A licensee shall provide reliable signal coverage and offer service within twelve (12) years from the
               date of the initial license to at least seventy-five (75) percent of the population in each of its license
               areas (“Final Buildout Requirement”).

           (3) If a licensee fails to establish that it meets the Interim Buildout Requirement for a particular licensed
               area, then the Final Buildout Requirement (in this paragraph (t)) and the license term (as set forth in
               § 27.13(l)) for each license area in which it fails to meet the Interim Buildout Requirement shall be
               accelerated by two (2) years (from twelve (12) to ten (10) years).

           (4) If a licensee fails to establish that it meets the Final Buildout Requirement for a particular license
               area, its authorization for each license area in which it fails to meet the Final Buildout Requirement
               shall terminate automatically without Commission action, and the licensee will be ineligible to regain
               it if the Commission makes the license available at a later date.

           (5) To demonstrate compliance with these performance requirements, licensees shall use the most
               recently available decennial U.S. Census Data at the time of measurement and shall base their
               measurements of population served on areas no larger than the Census Tract level. The population
               within a specific Census Tract (or other acceptable identifier) will be deemed served by the licensee
               only if it provides reliable signal coverage to and offers service within the specific Census Tract (or
               other acceptable identifier). To the extent the Census Tract (or other acceptable identifier) extends
               beyond the boundaries of a license area, a licensee with authorizations for such areas may include
               only the population within the Census Tract (or other acceptable identifier) towards meeting the
               performance requirement of a single, individual license. For the Gulf of Mexico license area, the

                licensee shall demonstrate compliance with these performance requirements, using off-shore
                platforms, including production, manifold, compression, pumping and valving platforms as a proxy
                for population in the Gulf of Mexico.

     (u) This section enumerates performance requirements for EBS licenses initially issued after October 25,
         2019. Licensees shall demonstrate compliance with performance requirements by filing a construction
         notification with the Commission, within 15 days of the expiration of the applicable benchmark, in
         accordance with the provisions set forth in § 1.946(d) of this chapter.

           (1) All EBS licenses initially issued after October 25, 2019, must demonstrate compliance with the
               performance requirements described in this paragraph (u). All equipment used to demonstrate
               compliance must be in use and actually providing service, either for internal use or to unaffiliated
               customers, as of the interim deadline or final deadline, whichever is applicable.

           (2) Except for licensees with licenses applied for in the Tribal Priority Window, licensees providing
               mobile or point-to-multipoint service must demonstrate reliable signal coverage of 50% of the
               population of the geographic service area within four years of initial license grant, and 80% of the
               population of the geographic service area within eight years of initial license grant.

           (3) Except for licensees with licenses applied for in the Tribal Priority Window, licensees providing fixed
               point-to-point service must demonstrate operation of one link for each 50,000 persons in the
               geographic service area within four years of initial license grant, and one link for each 25,000
               persons in the geographic service area within eight years of initial license grant.

           (4) Licensees with licenses applied for in the Tribal Priority Window must make an interim showing
               under paragraph (u)(2) or (3) of this section within two years of initial license grant. Licensees with
               licenses applied for in the Tribal Priority Window must make a final showing under paragraph (u)(2)
               or (3) of this section within five years of initial license grant.

           (5) If an EBS licensee (other than the licensee of a license issued pursuant to the Tribal Priority Window)
               fails to meet interim performance requirements described in paragraph (u)(2) or (3) of this section,
               the deadline for that authorization to meet its final performance requirement will be advanced by two
               years. If an EBS licensee of a license issued pursuant to the Tribal Priority Window fails to meet
               interim performance requirements described in paragraph (u)(2) or (3) of this section, the deadline
               for that authorization to meet its final performance requirement will be advanced by one year. If an
               EBS licensee fails to meet its final performance requirement, its license shall automatically terminate
               without specific Commission action.

     (v) The following provisions apply to any licensee holding an authorization in the 3700–3980 MHz band:

           (1) Licensees relying on mobile or point-to-multipoint service shall provide reliable signal coverage and
               offer service within eight (8) years from the date of the initial license to at least forty-five (45)
               percent of the population in each of its license areas (“First Buildout Requirement”). Licensee shall
               provide reliable signal coverage and offer service within twelve (12) years from the date of the initial
               license to at least eighty (80) percent of the population in each of its license areas (“Second Buildout
               Requirement”). Licensees relying on point-to-point service shall demonstrate within eight years of
               the license issue date that they have four links operating and providing service to customers or for
               internal use if the population within the license area is equal to or less than 268,000 and, if the
               population is greater than 268,000, that they have at least one link in operation and providing service
               to customers, or for internal use, per every 67,000 persons within a license area (“First Buildout
               Requirement”). Licensees relying on point-to-point service shall demonstrate within 12 years of the
               license issue date that they have eight links operating and providing service to customers or for

                internal use if the population within the license area is equal to or less than 268,000 and, if the
                population within the license area is greater than 268,000, shall demonstrate they are providing
                service and have at least two links in operation per every 67,000 persons within a license area
                (“Second Buildout Requirement”).

           (2) In the alternative, a licensee offering Internet of Things-type services shall provide geographic area
               coverage within eight (8) years from the date of the initial license to thirty-five (35) percent of the
               license (“First Buildout Requirement”). A licensee offering Internet of Things-type services shall
               provide geographic area coverage within twelve (12) years from the date of the initial license to sixty-
               five (65) percent of the license (“Second Buildout Requirement”).

           (3) If a licensee fails to establish that it meets the First Buildout Requirement for a particular license
               area, the licensee's Second Buildout Requirement deadline and license term will be reduced by two
               years. If a licensee fails to establish that it meets the Second Buildout Requirement for a particular
               license area, its authorization for each license area in which it fails to meet the Second Buildout
               Requirement shall terminate automatically without Commission action, and the licensee will be
               ineligible to regain it if the Commission makes the license available at a later date.

           (4) To demonstrate compliance with these performance requirements, licensees shall use the most
               recently available decennial U.S. Census Data at the time of measurement and shall base their
               measurements of population or geographic area served on areas no larger than the Census Tract
               level. The population or area within a specific Census Tract (or other acceptable identifier) will be
               deemed served by the licensee only if it provides reliable signal coverage to and offers service within
               the specific Census Tract (or other acceptable identifier). To the extent the Census Tract (or other
               acceptable identifier) extends beyond the boundaries of a license area, a licensee with
               authorizations for such areas may include only the population or geographic area within the Census
               Tract (or other acceptable identifier) towards meeting the performance requirement of a single,
               individual license. If a licensee does not provide reliable signal coverage to an entire license area, the
               license must provide a map that accurately depicts the boundaries of the area or areas within each
               license area not being served. Each licensee also must file supporting documentation certifying the
               type of service it is providing for each licensed area within its service territory and the type of
               technology used to provide such service. Supporting documentation must include the assumptions
               used to create the coverage maps, including the propagation model and the signal strength
               necessary to provide reliable service with the licensee's technology.

     (w) The following provisions apply to any licensee holding an authorization in the 3450–3550 MHz band:

           (1) Performance requirements. Licensees in the 3.45 GHz Service must meet the following benchmarks,
               based on the type of service they provide.

                 (i)   Mobile/point-to-multipoint service. Licensees relying on mobile or point-to-multipoint service
                       shall provide reliable signal coverage and offer service within four (4) years from the date of the
                       initial license to at least forty-five (45) percent of the population in each of its license areas
                       (“First Performance Benchmark”). Licensees shall provide reliable signal coverage and offer
                       service within eight (8) years from the date of the initial license to at least eighty (80) percent of
                       the population in each of its license areas (“Second Performance Benchmark”).

                 (ii) Point-to-point service. Licensees relying on point-to-point service shall demonstrate within four
                      (4) years of the license issue date that, if the population within the license area is equal to or
                      less than 268,000, they have four links operating and either provide service to customers or for
                      internal use. If the population is greater than 268,000, they shall demonstrate they have at least

                      67,000 persons within a license area (“First Performance Benchmark”). Licensees shall
                      demonstrate within eight (8) years of the license issue date that, if the population within license
                      area is equal to or less than 268,000, they have eight links operating and either provide service
                      to customers or for internal use. If the population within the license area is greater than
                      268,000, they shall demonstrate they have at least two links in operation and either provide
                      service to customers or for internal use per every 67,000 persons within a license area
                      (“Second Performance Benchmark”).

                (iii) Internet of Things service. Licensees offering Internet of Things-type services shall provide
                      geographic area coverage within four (4) years from the date of the initial license to thirty-five
                      (35) percent of the license (“First Performance Benchmark”). Licensees shall provide
                      geographic area coverage within eight (8) years from the date of the initial license to sixty-five
                      (65) percent of the license (“Second Performance Benchmark”).

           (2) Failure to meet performance requirements. If a licensee fails to establish that it meets the First
               Performance Benchmark for a particular license area in paragraph (w)(1) of this section, the
               licensee's Second Performance Benchmark deadline and license term in paragraph (w)(1) of this
               section will be reduced by one year. If a licensee fails to establish that it meets the Second
               Performance Benchmark for a particular license area, its authorization for each license area in which
               it fails to meet the Second Performance Benchmark shall terminate automatically without
               Commission action, and the licensee will be ineligible to regain it if the Commission makes the
               license available at a later date.

           (3) Compliance procedures. To demonstrate compliance with the performance requirements in
               paragraph (w)(1) of this section, licensees shall use the most recently available decennial U.S.
               Census Data at the time of measurement and shall base their measurements of population or
               geographic area served on areas no larger than the Census Tract level. The population or area within
               a specific Census Tract (or other acceptable identifier) will be deemed served by the licensee only if
               it provides reliable signal coverage to and offers service within the specific Census Tract (or other
               acceptable identifier). To the extent the Census Tract (or other acceptable identifier) extends beyond
               the boundaries of a license area, a licensee with authorizations for such areas may include only the
               population or geographic area within the Census Tract (or other acceptable identifier) towards
               meeting the performance requirement of a single, individual license. If a licensee does not provide
               reliable signal coverage to an entire license area, the license must provide a map that accurately
               depicts the boundaries of the area or areas within each license area not being served. Each licensee
               also must file supporting documentation certifying the type of service it is providing for each
               licensed area within its service territory and the type of technology used to provide such service.
               Supporting documentation must include the assumptions used to create the coverage maps,
               including the propagation model and the signal strength necessary to provide reliable service with
               the licensee's technology.

§ 27.15 Geographic partitioning and spectrum disaggregation.
     (a) Eligibility.

           (1) Parties seeking approval for partitioning and disaggregation shall request from the Commission an
               authorization for partial assignment of a license pursuant to § 1.948.

           (2) AWS and WCS licensees may apply to partition their licensed geographic service area or
               disaggregate their licensed spectrum at any time following the grant of their licenses.

     (b) Technical Standards —

           (1) Partitioning. In the case of partitioning, applicants and licensees must file FCC Form 603 pursuant to
               section 1.948 and list the partitioned service area on a schedule to the application. The geographic
               coordinates must be specified in degrees, minutes, and seconds to the nearest second of latitude
               and longitude and must be based upon the 1983 North American Datum (NAD83).

           (2) Disaggregation. Spectrum may be disaggregated in any amount.

           (3) Combined partitioning and disaggregation. The Commission will consider requests for partial
               assignment of licenses that propose combinations of partitioning and disaggregation.

           (4) Signal levels. For purposes of partitioning and disaggregation, part 27 systems must be designed so
               as not to exceed the signal level specified for the particular spectrum block in § 27.55 at the
               licensee's service area boundary, unless the affected adjacent service area licensees have agreed to
               a different signal level.

     (c) License term. The license term for a partitioned license area and for disaggregated spectrum shall be the
         remainder of the original licensee's license term as provided for in § 27.13.

§ 27.16 Network access requirements for Block C in the 746–757 and 776–787 MHz bands.
     (a) Applicability. This section shall apply only to the authorizations for Block C in the 746–757 and 776–787
         MHz bands assigned and only if the results of the first auction in which licenses for such authorizations
         are offered satisfied the applicable reserve price.

     (b) Use of devices and applications. Licensees offering service on spectrum subject to this section shall not
         deny, limit, or restrict the ability of their customers to use the devices and applications of their choice on
         the licensee's C Block network, except:

           (1) Insofar as such use would not be compliant with published technical standards reasonably
               necessary for the management or protection of the licensee's network, or

           (2) As required to comply with statute or applicable government regulation.

     (c) Technical standards. For purposes of paragraph (b)(1) of this section:

           (1) Standards shall include technical requirements reasonably necessary for third parties to access a
               licensee's network via devices or applications without causing objectionable interference to other
               spectrum users or jeopardizing network security. The potential for excessive bandwidth demand
               alone shall not constitute grounds for denying, limiting or restricting access to the network.

           (2) To the extent a licensee relies on standards established by an independent standards-setting body
               which is open to participation by representatives of service providers, equipment manufacturers,
               application developers, consumer organizations, and other interested parties, the standards will
               carry a presumption of reasonableness.

           (3) A licensee shall publish its technical standards, which shall be non-proprietary, no later than the time
               at which it makes such standards available to any preferred vendors, so that the standards are
               readily available to customers, equipment manufacturers, application developers, and other parties
               interested in using or developing products for use on a licensee's networks.

     (d) Access requests.

           (1) Licensees shall establish and publish clear and reasonable procedures for parties to seek approval
               to use devices or applications on the licensees' networks. A licensee must also provide to potential
               customers notice of the customers' rights to request the attachment of a device or application to the
               licensee's network, and notice of the licensee's process for customers to make such requests,
               including the relevant network criteria.

           (2) If a licensee determines that a request for access would violate its technical standards or regulatory
               requirements, the licensee shall expeditiously provide a written response to the requester specifying
               the basis for denying access and providing an opportunity for the requester to modify its request to
               satisfy the licensee's concerns.

     (e) Handset locking prohibited. No licensee may disable features on handsets it provides to customers, to the
         extent such features are compliant with the licensee's standards pursuant to paragraph (b)of this section,
         nor configure handsets it provides to prohibit use of such handsets on other providers' networks.

     (f) Burden of proof. Once a complainant sets forth a prima facie case that the C Block licensee has refused
         to attach a device or application in violation of the requirements adopted in this section, the licensee shall
         have the burden of proof to demonstrate that it has adopted reasonable network standards and
         reasonably applied those standards in the complainant's case. Where the licensee bases its network
         restrictions on industry-wide consensus standards, such restrictions would be presumed reasonable.

§ 27.50 Power limits and duty cycle.
     (a) The following power limits and related requirements apply to stations transmitting in the 2305–2320 MHz
         band or the 2345–2360 MHz band.

           (1) Base and fixed stations.

                 (i)   For base and fixed stations transmitting in the 2305–2315 MHz band or the 2350–2360 MHz
                       band:

                       (A) The average equivalent isotropically radiated power (EIRP) must not exceed 2,000 watts
                           within any 5 megahertz of authorized bandwidth and must not exceed 400 watts within
                           any 1 megahertz of authorized bandwidth.

Miscellaneous Wireless Communications Services

                      (B) The peak-to-average power ratio (PAPR) of the transmitter output power must not exceed
                          13 dB. The PAPR measurements should be made using either an instrument with
                          complementary cumulative distribution function (CCDF) capabilities to determine that
                          PAPR will not exceed 13 dB for more than 0.1 percent of the time or other Commission
                          approved procedure. The measurement must be performed using a signal corresponding
                          to the highest PAPR expected during periods of continuous transmission.

                (ii) For base and fixed stations transmitting in the 2315–2320 MHz band or the 2345–2350 MHz
                     band, the peak EIRP must not exceed 2,000 watts.

          (2) Fixed customer premises equipment stations. For fixed customer premises equipment (CPE) stations
              transmitting in the 2305–2320 MHz band or in the 2345–2360 MHz band, the peak EIRP must not
              exceed 20 watts within any 5 megahertz of authorized bandwidth. Fixed CPE stations transmitting in
              the 2305–2320 MHz band or in the 2345–2360 MHz band must employ automatic transmit power
              control when operating so the stations operate with the minimum power necessary for successful
              communications. The use of outdoor antennas for CPE stations or outdoor CPE station installations
              operating with 2 watts per 5 megahertz or less average EIRP using the stepped emissions mask
              prescribed in § 27.53(a)(3) is prohibited except if professionally installed in locations removed by 20
              meters from roadways or in locations where it can be shown that the ground power level of −44 dBm
              in the A or B blocks or −55 dBm in the C or D blocks will not be exceeded at the nearest road
              location. The use of outdoor antennas for fixed CPE stations operating with 2 watts per 5 megahertz
              or less average EIRP and the emissions mask prescribed in § 27.53(a)(1)(i) through (iii) is permitted
              in all locations. For fixed WCS CPE using TDD technology, the duty cycle must not exceed 38 percent;

          (3) Mobile and portable stations.

                (i)   For mobile and portable stations transmitting in the 2305–2315 MHz band or the 2350–2360
                      MHz band, the average EIRP must not exceed 50 milliwatts within any 1 megahertz of
                      authorized bandwidth, except that for mobile and portable stations compliant with 3GPP LTE
                      standards or another advanced mobile broadband protocol that avoids concentrating energy at
                      the edge of the operating band the average EIRP must not exceed 250 milliwatts within any 5
                      megahertz of authorized bandwidth but may exceed 50 milliwatts within any 1 megahertz of
                      authorized bandwidth. For mobile and portable stations using time division duplexing (TDD)
                      technology, the duty cycle must not exceed 38 percent in the 2305–2315 MHz and 2350–2360
                      MHz bands. Mobile and portable stations using FDD technology are restricted to transmitting in
                      the 2305–2315 MHz band. Power averaging shall not include intervals in which the transmitter
                      is off.

                (ii) Mobile and portable stations are not permitted to transmit in the 2315–2320 MHz and
                     2345–2350 MHz bands.

               (iii) Automatic transmit power control. Mobile and portable stations transmitting in the 2305–2315
                     MHz band or in the 2350–2360 MHz band must employ automatic transmit power control
                     when operating so the stations operate with the minimum power necessary for successful
                     communications.

               (iv) Prohibition on external vehicle-mounted antennas. The use of external vehicle-mounted
                    antennas for mobile and portable stations transmitting in the 2305–2315 MHz band or the
                    2350–2360 MHz band is prohibited.

          (13) Licensees authorized to operate in the 716–722 or 722–728 MHz bands must coordinate with
               licensees with uplink operations in the 698–716 MHz band to mitigate the potential for harmful
               interference. Licensees authorized to operate in the 716–722 or 722–728 MHz bands must mitigate
               harmful interference to licensees' uplink operations in the 698–716 MHz band within 30 days after
               receiving written notice from the affected licensees. A licensee authorized to operate in the 716–722
               or 722–728 MHz bands must ensure that 716–728 MHz band transmissions are filtered at least to
               the extent that the 716–728 MHz band transmissions are filtered in markets where the 716–728
               MHz band licensee holds any license in the 698–716 band, as applicable. For purposes of
               coordination and mitigations measures in paragraphs (i) and (iii) below, network will be deemed
               “deployed” as of the date upon which the network is able to support a commercial mobile or data
               service. The coordination and mitigation measures should include, but are not limited to, the
               following:

                 (i)   If a licensee operating in the 698–716 and 728–746 MHz band deploys a network after the
                       716–722 or 722–728 MHz bands licensee deploys a network on its 716–722 or 722–728 MHz
                       spectrum in the same geographic market, the 716–722 or 722–728 MHz bands licensee will
                       work with the licensee with uplink operations in the 698–716 MHz band to identify sites that
                       will require additional filtering, and will help the licensee operating in the 698–716 and 728–746
                       MHz bands to identify proper filters;

                 (ii) The 716–722 or 722–728 MHz bands licensee must permit licensees operating in the 698–716
                      and 728–746 MHz bands to collocate on the towers it owns at prevailing market rates; and

                (iii) If a 698–716 and 728–746 MHz bands licensee deploys a network before a licensee in the
                      716–722 or 722–728 MHz bands deploys a network in the same geographic market, the
                      716–722 or 722–728 MHz bands licensee will work with licensees in the 698–716 and
                      728–746 MHz bands to identify sites that will need additional filtering and will purchase and
                      pay for installation of required filters on such sites.

     (d) The following power and antenna height requirements apply to stations transmitting in the 1695–1710
         MHz, 1710–1755 MHz, 1755–1780 MHz, 1915–1920 MHz, 1995–2000 MHz, 2000–2020 MHz,

          (3) A licensee operating a base or fixed station in the 2110–2155 MHz band utilizing a power greater
              than 1640 watts EIRP and greater than 1640 watts/MHz EIRP must coordinate such operations in
              advance with all Government and non-Government satellite entities in the 2025–2110 MHz band. A
              licensee operating a base or fixed station in the 2110–2180 MHz band utilizing power greater than
              1640 watts EIRP and greater than 1640 watts/MHz EIRP must be coordinated in advance with the
              following licensees authorized to operate within 120 kilometers (75 miles) of the base or fixed
              station operating in this band: All Broadband Radio Service (BRS) licensees authorized under this
              part in the 2155–2160 MHz band and all advanced wireless services (AWS) licensees authorized to
              operate on adjacent frequency blocks in the 2110–2180 MHz band.

          (4) Fixed, mobile, and portable (hand-held) stations operating in the 1710–1755 MHz band and mobile

              employ a means for limiting power to the minimum necessary for successful communications.

          (5) Equipment employed must be authorized in accordance with the provisions of § 24.51. Power
              measurements for transmissions by stations authorized under this section may be made either in
              accordance with a Commission-approved average power technique or in compliance with paragraph
              (d)(6) of this section. In measuring transmissions in this band using an average power technique, the
              peak-to-average ratio (PAR) of the transmission may not exceed 13 dB.

          (6) Peak transmit power must be measured over any interval of continuous transmission using
              instrumentation calibrated in terms of an rms-equivalent voltage. The measurement results shall be
              properly adjusted for any instrument limitations, such as detector response times, limited resolution
              bandwidth capability when compared to the emission bandwidth, sensitivity, etc., so as to obtain a
              true peak measurement for the emission in question over the full bandwidth of the channel.

          (7) Fixed, mobile, and portable (hand-held) stations operating in the 2000–2020 MHz band are limited to
              2 watts EIRP, except that the total power of any portion of an emission that falls within the
              2000–2005 MHz band may not exceed 5 milliwatts. A licensee of AWS–4 authority may enter into
              private operator-to-operator agreements with all 1995–2000 MHz licensees to operate in 2000–2005
              MHz at power levels above 5 milliwatts EIRP; except the total power of the AWS–4 mobile emissions
              may not exceed 2 watts EIRP.

          (8) A licensee operating a base or fixed station in the 2180–2200 MHz band utilizing a power greater
              than 1640 watts EIRP and greater than 1640 watts/MHz EIRP must be coordinated in advance with

     (g) [Reserved]

     (h) The following power limits shall apply in the BRS and EBS:

          (1) Main, booster and base stations.

                (i)   The maximum EIRP of a main, booster or base station shall not exceed 33 dBW + 10log(X/Y)
                      dBW, where X is the actual channel width in MHz and Y is either 6 MHz if prior to transition or
                      the station is in the MBS following transition or 5.5 MHz if the station is in the LBS and UBS
                      following transition, except as provided in paragraph (h)(1)(ii) of this section.

                (ii) If a main or booster station sectorizes or otherwise uses one or more transmitting antennas
                     with a non-omnidirectional horizontal plane radiation pattern, the maximum EIRP in dBW in a
                     given direction shall be determined by the following formula: EIRP = 33 dBW + 10 log(X/Y) dBW
                     + 10 log(360/beamwidth) dBW, where X is the actual channel width in MHz, Y is either (i) 6 MHz
                     if prior to transition or the station is in the MBS following transition or (ii) 5.5 MHz if the station
                     is in the LBS and UBS following transition, and beamwidth is the total horizontal plane
                     beamwidth of the individual transmitting antenna for the station or any sector measured at the
                     half-power points.

          (2) Mobile and other user stations. Mobile stations are limited to 2.0 watts EIRP. All user stations are
              limited to 2.0 watts transmitter output power.

          (3) For television transmission, the peak power of the accompanying aural signal must not exceed 10
              percent of the peak visual power of the transmitter. The Commission may order a reduction in aural
              signal power to diminish the potential for harmful interference.

          (4) For main, booster and response stations utilizing digital emissions with non-uniform power spectral
              density (e.g. unfiltered QPSK), the power measured within any 100 kHz resolution bandwidth within
              the 6 MHz channel occupied by the non-uniform emission cannot exceed the power permitted within
              any 100 kHz resolution bandwidth within the 6 MHz channel if it were occupied by an emission with
              uniform power spectral density, i.e., if the maximum permissible power of a station utilizing a
              perfectly uniform power spectral density across a 6 MHz channel were 2000 watts EIRP, this would
              result in a maximum permissible power flux density for the station of 2000/60 = 33.3 watts EIRP per
              100 kHz bandwidth. If a non-uniform emission were substituted at the station, station power would
              still be limited to a maximum of 33.3 watts EIRP within any 100 kHz segment of the 6 MHz channel,
              irrespective of the fact that this would result in a total 6 MHz channel power of less than 2000 watts
              EIRP.

               bandwidth capability when compared to the emission bandwidth, sensitivity, and any other relevant
               factors, so as to obtain a true peak measurement for the emission in question over the full
               bandwidth of the channel.

     (k) The following power requirements apply to stations transmitting in the 3450–3550 MHz band:

           (1) The power of each fixed or base station transmitting in the 3450–3550 MHz band and located in any
               county with population density of 100 or fewer persons per square mile, based upon the most
               recently available population statistics from the Bureau of the Census, is limited to an equivalent
               isotropically radiated power (EIRP) of 3280 Watts/MHz. This limit applies to the aggregate power of
               all antenna elements in any given sector of a base station.

           (2) The power of each fixed or base station transmitting in the 3450–3550 MHz band and situated in any
               geographic location other than that described in paragraph (k)(1) of this section is limited to an EIRP
               of 1640 Watts/MHz. This limit applies to the aggregate power of all antenna elements in any given

              peak-to-average ratio (PAR) of the transmission may not exceed 13 dB.

          (5) Peak transmit power must be measured over any interval of continuous transmission using
              instrumentation calibrated in terms of an rms-equivalent voltage. The measurement results shall be
              properly adjusted for any instrument limitations, such as detector response times, limited resolution
              bandwidth capability when compared to the emission bandwidth, sensitivity, and any other relevant
              factors, so as to obtain a true peak measurement for the emission in question over the full
              bandwidth of the channel.

          (5) Measurement procedure. Compliance with these rules is based on the use of measurement
              instrumentation employing a resolution bandwidth of 1 MHz or greater. However, in the 1 MHz bands
              immediately outside and adjacent to the channel blocks at 2305, 2310, 2315, 2320, 2345, 2350,
              2355, and 2360 MHz, a resolution bandwidth of at least 1 percent of the emission bandwidth of the
              fundamental emission of the transmitter may be employed. A narrower resolution bandwidth is
              permitted in all cases to improve measurement accuracy provided the measured power is integrated
              over the full required measurement bandwidth (i.e., 1 MHz). The emission bandwidth is defined as
              the width of the signal between two points, one below the carrier center frequency and one above
              the carrier center frequency, outside of which all emissions are attenuated at least 26 dB below the
              transmitter power.

          (6) [Reserved]

          (7) The measurements of emission power can be expressed in peak or average values, provided they are
              expressed in the same parameters as the transmitter power;

          (8) Waiver requests of any of the out-of-band emission limits in paragraphs (a)(1) through (a)(7) of this
              section shall be entertained only if interference protection equivalent to that afforded by the limits is
              shown;

          (9) [Reserved]

          (10) The out-of-band emissions limits in paragraphs (a)(1) through (a)(3) of this section may be modified
               by the private contractual agreement of all affected licensees, who must maintain a copy of the
               agreement in their station files and disclose it to prospective assignees, transferees, or spectrum
               lessees and, upon request, to the Commission.

     (b) For WCS Satellite DARS operations: The limits set forth in § 25.202(f) of this chapter shall apply, except
         that Satellite DARS operations shall be limited to a maximum power flux density of −197 dBW/m2/4 kHz
         in the 2370–2390 MHz band at Arecibo, Puerto Rico.

     (c) For operations in the 746–758 MHz band and the 776–788 MHz band, the power of any emission outside
         the licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within
         the licensed band(s) of operation, measured in watts, in accordance with the following:

          (1) On any frequency outside the 746–758 MHz band, the power of any emission shall be attenuated
              outside the band below the transmitter power (P) by at least 43 + 10 log (P) dB;

          (2) On any frequency outside the 776–788 MHz band, the power of any emission shall be attenuated
              outside the band below the transmitter power (P) by at least 43 + 10 log (P) dB;

          (3) On all frequencies between 763–775 MHz and 793–805 MHz, by a factor not less than 76 + 10 log
              (P) dB in a 6.25 kHz band segment, for base and fixed stations;

          (4) On all frequencies between 763–775 MHz and 793–805 MHz, by a factor not less than 65 + 10 log
              (P) dB in a 6.25 kHz band segment, for mobile and portable stations;

          (5) Compliance with the provisions of paragraphs (c)(1) and (c)(2) of this section is based on the use of
              measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in
              the 100 kHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth
              of at least 30 kHz may be employed;

          (6) Compliance with the provisions of paragraphs (c)(3) and (c)(4) of this section is based on the use of
              measurement instrumentation such that the reading taken with any resolution bandwidth setting
              should be adjusted to indicate spectral energy in a 6.25 kHz segment.

     (d) [Reserved]

     (e) For operations in the 775–776 MHz and 805–806 MHz bands, transmitters must comply with either
         paragraphs (d)(1) through (5) of this section or the ACP emission limitations set forth in paragraphs (d)(6)
         to (d)(9) of this section.

          (1) On all frequencies between 758–775 MHz and 788–805 MHz, the power of any emission outside the
              licensee's frequency bands of operation shall be attenuated below the transmitter power (P) within
              the licensed band(s) of operation, measured in watts, by a factor not less than 76 + 10 log (P) dB in a
              6.25 kHz band segment, for base and fixed stations;

          (2) On all frequencies between 758–775 MHz and 788–805 MHz, the power of any emission outside the
              licensee's frequency bands of operation shall be attenuated below the transmitter power (P) within
              the licensed band(s) of operation, measured in watts, by a factor not less than 65 + 10 log (P) dB in a
              6.25 kHz band segment, for mobile and portable stations;

          (3) On any frequency outside the 775–776 MHz and 805–806 MHz bands, the power of any emission
              shall be attenuated outside the band below the transmitter power (P) within the licensed band(s) of
              operation, measured in watts, by at least 43 + 10 log (P) dB;

          (4) Compliance with the provisions of paragraphs (e)(1) and (e)(2) of this section is based on the use of
              measurement instrumentation such that the reading taken with any resolution bandwidth setting
              should be adjusted to indicate spectral energy in a 6.25 kHz segment;

          (5) Compliance with the provisions of paragraph (e)(3) of this section is based on the use of
              measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in
              the 100 kHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth
              of at least 30 kHz may be employed.

          (6) The adjacent channel power (ACP) requirements for transmitters designed for various channel sizes
              are shown in the following tables. Mobile station requirements apply to handheld, car mounted and
              control station units. The tables specify a value for the ACP as a function of the displacement from
              the channel center frequency and measurement bandwidth. In the following tables, “(s)” indicates a
              swept measurement may be used.

          (7) ACP measurement procedure. The following procedures are to be followed for making ACP
              transmitter measurements. For time division multiple access (TDMA) systems, the measurements
              are to be made under TDMA operation only during time slots when the transmitter is on. All
              measurements must be made at the input to the transmitter's antenna. Measurement bandwidth
              used below implies an instrument that measures the power in many narrow bandwidths (e.g., 300
              Hz) and integrates these powers across a larger band to determine power in the measurement
              bandwidth.

                (i)   Setting reference level. Using a spectrum analyzer capable of ACP measurements, set the
                      measurement bandwidth to the channel size. For example, for a 6.25 kHz transmitter, set the
                      measurement bandwidth to 6.25 kHz; for a 150 kHz transmitter, set the measurement
                      bandwidth to 150 kHz. Set the frequency offset of the measurement bandwidth to zero and
                      adjust the center frequency of the spectrum analyzer to give the power level in the
                      measurement bandwidth. Record this power level in dBm as the “reference power level”.

                (ii) Non-swept power measurement. Using a spectrum analyzer capable of ACP measurements, set
                     the measurement bandwidth as shown in the tables above. Measure the ACP in dBm. These
                     measurements should be made at maximum power. Calculate the coupled power by
                     subtracting the measurements made in this step from the reference power measured in the
                     previous step. The absolute ACP values must be less than the values given in the table for each
                     condition above.

                (iii) Swept power measurement. Set a spectrum analyzer to 30 kHz resolution bandwidth, 1 MHz
                      video bandwidth and sample mode detection. Sweep ±MHz from the carrier frequency. Set the
                      reference level to the RMS value of the transmitter power and note the absolute power. The
                      response at frequencies greater than 600 kHz must be less than the values in the tables above.

          (8) Out-of-band emission limit. On any frequency outside of the frequency ranges covered by the ACP
              tables in this section, the power of any emission must be reduced below the unmodulated carrier
              power (P) by at least 43 + 10 log (P) dB.

          (9) Authorized bandwidth. Provided that the ACP requirements of this section are met, applicants may
              request any authorized bandwidth that does not exceed the channel size.

     (f) For operations in the 746–758 MHz, 775–788 MHz, and 805–806 MHz bands, emissions in the band
         1559–1610 MHz shall be limited to −70 dBW/MHz equivalent isotropically radiated power (EIRP) for
         wideband signals, and −80 dBW EIRP for discrete emissions of less than 700 Hz bandwidth. For the
         purpose of equipment authorization, a transmitter shall be tested with an antenna that is representative of
         the type that will be used with the equipment in normal operation.

     (g) For operations in the 600 MHz band and the 698–746 MHz band, the power of any emission outside a
         licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within the
         licensed band(s) of operation, measured in watts, by at least 43 + 10 log (P) dB. Compliance with this
         provision is based on the use of measurement instrumentation employing a resolution bandwidth of 100
         kilohertz or greater. However, in the 100 kilohertz bands immediately outside and adjacent to a licensee's
         frequency block, a resolution bandwidth of at least 30 kHz may be employed.

Miscellaneous Wireless Communications Services

           (1) General protection levels. Except as otherwise specified below, for operations in the 1695–1710
               MHz, 1710–1755 MHz, 1755–1780 MHz, 1915–1920 MHz, 1995–2000 MHz, 2000–2020 MHz,
               2110–2155 MHz, 2155–2180 MHz, and 2180–2200 bands, the power of any emission outside a
               licensee's frequency block shall be attenuated below the transmitter power (P) in watts by at least 43
               + 10 log10 (P) dB.

           (2) Additional protection levels. Notwithstanding the foregoing paragraph (h)(1) of this section:

                 (i)   Operations in the 2180–2200 MHz band are subject to the out-of-band emission requirements
                       set forth in § 27.1134 for the protection of federal government operations operating in the
                       2200–2290 MHz band.

                 (ii) For operations in the 2000–2020 MHz band, the power of any emissions below 2000 MHz shall
                      be attenuated below the transmitter power (P) in watts by at least 70 + 10 log10(P) dB.

                (iii) For operations in the 1915–1920 MHz band, the power of any emission between 1930–1995
                      MHz shall be attenuated below the transmitter power (P) in watts by at least 70 + 10 log10(P)
                      dB.

                (iv) For operations in the 1995–2000 MHz band, the power of any emission between 2005–2020
                     MHz shall be attenuated below the transmitter power (P) in watts by at least 70 + 10 log10(P)
                     dB.

           (3) Measurement procedure.

                 (i)   Compliance with this provision is based on the use of measurement instrumentation employing
                       a resolution bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands
                       immediately outside and adjacent to the licensee's frequency block, a resolution bandwidth of
                       at least one percent of the emission bandwidth of the fundamental emission of the transmitter
                       may be employed. The emission bandwidth is defined as the width of the signal between two
                       points, one below the carrier center frequency and one above the carrier center frequency,
                       outside of which all emissions are attenuated at least 26 dB below the transmitter power.

                 (ii) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to
                      the licensee's frequency block edges, both upper and lower, as the design permits.

                (iii) The measurements of emission power can be expressed in peak or average values, provided
                      they are expressed in the same parameters as the transmitter power.

           (4) Private agreements.

                 (i)   For AWS operations in the 2000–2020 MHz and 2180–2200 MHz bands, to the extent a
                       licensee establishes unified operations across the AWS blocks, that licensee may choose not to
                       observe the emission limit specified in paragraph (h)(1), above, strictly between its adjacent
                       block licenses in a geographic area, so long as it complies with other Commission rules and is
                       not adversely affecting the operations of other parties by virtue of exceeding the emission limit.

                 (ii) For AWS operations in the 2000–2020 MHz band, a licensee may enter into private agreements
                      with all licensees operating between 1995 and 2000 MHz to allow the 70 + 10 log10(P) dB limit
                      to be exceeded within the 1995–2000 MHz band.

                (iii) An AWS licensee who is a party to a private agreement described in this section (4) must
                      maintain a copy of the agreement in its station files and disclose it, upon request, to
                      prospective AWS assignees, transferees, or spectrum lessees and to the Commission.

     (i)   When an emission outside of the authorized bandwidth causes harmful interference, the Commission
           may, at its discretion, require greater attenuation than specified in this section.

     (j)

           (1) For operations in the unpaired 1390–1392 MHz band and the paired 1392–1395 MHz and
               1432–1435 MHz bands, the power of any emission outside the licensee's frequency band(s) of
               operation shall be attenuated below the transmitter power (P) by at least 43 + 10 log (P) dB.
               Compliance with these provisions is based on the procedures described in paragraph (a)(5) of this
               section.

           (2) In the 1390–1395 MHz and 1432–1435 MHz bands, licensees are encouraged to take all reasonable
               steps to ensure that unwanted emission power does not exceed the following levels in the band
               1400–1427 MHz:

                (i)   For stations of point-to-point systems in the fixed service: −45 dBW/27 MHz.

                (ii) For stations in the mobile service: −60 dBW/27 MHz.

     (k) For operations in the 1670–1675 MHz, the power of any emission outside the licensee's frequency
         band(s) of operation shall be attenuated below the transmitter power (P) by at least 43 + 10 log (P) dB.
         Compliance with these provisions is based on the procedures described in paragraph (a)(5) of this
         section.

     (l)   3.7 GHz Service. The following emission limits apply to stations transmitting in the 3700–3980 MHz band:

           (1) For base station operations in the 3700–3980 MHz band, the conducted power of any emission
               outside the licensee's authorized bandwidth shall not exceed −13 dBm/MHz. Compliance with this
               paragraph (l)(1) is based on the use of measurement instrumentation employing a resolution
               bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands immediately outside and
               adjacent to the licensee's frequency block, a resolution bandwidth of at least one percent of the
               emission bandwidth of the fundamental emission of the transmitter may be employed. The emission
               bandwidth is defined as the width of the signal between two points, one below the carrier center
               frequency and one above the carrier center frequency, outside of which all emissions are attenuated
               at least 26 dB below the transmitter power.

           (2) For mobile operations in the 3700–3980 MHz band, the conducted power of any emission outside
               the licensee's authorized bandwidth shall not exceed −13 dBm/MHz. Compliance with this
               paragraph (l)(2) is based on the use of measurement instrumentation employing a resolution
               bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands immediately outside and
               adjacent to the licensee's frequency block, the minimum resolution bandwidth for the measurement
               shall be either one percent of the emission bandwidth of the fundamental emission of the
               transmitter or 350 kHz. In the bands between 1 and 5 MHz removed from the licensee's frequency
               block, the minimum resolution bandwidth for the measurement shall be 500 kHz. The emission
               bandwidth is defined as the width of the signal between two points, one below the carrier center
               frequency and one above the carrier center frequency, outside of which all emissions are attenuated
               at least 26 dB below the transmitter power.

    (m) For BRS and EBS stations, the power of any emissions outside the licensee's frequency bands of
        operation shall be attenuated below the transmitter power (P) measured in watts in accordance with the
        standards below. If a licensee has multiple contiguous channels, out-of-band emissions shall be
        measured from the upper and lower edges of the contiguous channels.

          (1) Prior to the transition, and thereafter, solely within the MBS, for analog operations with an EIRP in
              excess of −9 dBW, the signal shall be attenuated at the channel edges by at least 38 dB relative to
              the peak visual carrier, then linearly sloping from that level to at least 60 dB of attenuation at 1 MHz
              below the lower band edge and 0.5 MHz above the upper band edge, and attenuated at least 60 dB
              at all other frequencies.

          (2) For digital base stations, the attenuation shall be not less than 43 + 10 log (P) dB, unless a
              documented interference complaint is received from an adjacent channel licensee with an
              overlapping Geographic Service Area. Mobile Satellite Service licensees operating on frequencies
              below 2495 MHz may also submit a documented interference complaint against BRS licensees
              operating on channel BRS No. 1 on the same terms and conditions as adjacent channel BRS or EBS
              licensees. Provided that a documented interference complaint cannot be mutually resolved between
              the parties prior to the applicable deadline, then the following additional attenuation requirements
              shall apply:

                (i)   If a pre-existing base station suffers harmful interference from emissions caused by a new or
                      modified base station located 1.5 km or more away, within 24 hours of the receipt of a
                      documented interference complaint the licensee of the new or modified base station must
                      attenuate its emissions by at least 67 + 10 log (P) dB measured at 3 megahertz, above or
                      below, from the channel edge of its frequency block and shall immediately notify the
                      complaining licensee upon implementation of the additional attenuation. No later than 60 days
                      after the implementation of such additional attenuation, the licensee of the complaining base
                      station must attenuate its base station emissions by at least 67 + 10 log (P) dB measured at 3
                      megahertz, above or below, from the channel edge of its frequency block of the new or
                      modified base station.

                (ii) If a pre-existing base station suffers harmful interference from emissions caused by a new or
                     modified base station located less than 1.5 km away, within 24 hours of receipt of a
                     documented interference complaint the licensee of the new or modified base station must
                     attenuate its emissions by at least 67 + 10 log (P)−20 log (Dkm/1.5) dB measured at 3
                     megahertz, above or below, from the channel edge of its frequency block of the complaining
                     licensee, or if both base stations are co-located, limit its undesired signal level at the pre-
                     existing base station receiver(s) to no more than −107 dBm measured in a 5.5 megahertz
                     bandwidth and shall immediately notify the complaining licensee upon such reduction in the
                     undesired signal level. No later than 60 days after such reduction in the undesired signal level,
                     the complaining licensee must attenuate its base station emissions by at least 67 + 10 log (P)
                     dB measured at 3 megahertz, above or below, from the channel edge of its frequency block of
                     the new or modified base station.

                (iii) If a new or modified base station suffers harmful interference from emissions caused by a pre-
                      existing base station located 1.5 km or more away, within 60 days of receipt of a documented
                      interference complaint the licensee of each base station must attenuate its base station
                      emissions by at least 67 + 10 log (P) dB measured at 3 megahertz, above or below, from the
                      channel edge of its frequency block of the other licensee.

                (iv) If a new or modified base station suffers harmful interference from emissions caused by a pre-
                     existing base station located less than 1.5 km away, within 60 days of receipt of a documented

                     located, limit its undesired signal level at the other base station receiver(s) to no more than
                     −107 dBm measured in a 5.5-megahertz bandwidth; and (b) the licensee causing the
                     interference must attenuate its emissions by at least 67 + 10 log (P) dB measured at 3
                     megahertz, above or below, from the channel edge of its frequency block of the new or
                     modified base station.

                (v) For all fixed digital user stations, the attenuation factor shall be not less than 43 + 10 log (P) dB
                    at the channel edge.

          (3) Prior to transition and thereafter solely within the MBS, and notwithstanding paragraph (l)(2) of this
              section, the maximum out-of-band power of a digital transmitter operating on a single 6 MHz
              channel with an EIRP in excess of −9 dBW employing digital modulation for the primary purpose of
              transmitting video programming shall be attenuated at the 6 MHz channel edges at least 25 dB
              relative to the licensed average 6 MHz channel power level, then attenuated along a linear slope to at
              least 40 dB at 250 kHz beyond the nearest channel edge, then attenuated along a linear slope from
              that level to at least 60 dB at 3 MHz above the upper and below the lower licensed channel edges,
              and attenuated at least 60 dB at all other frequencies.

          (4) For mobile digital stations, the attenuation factor shall be not less than 40 + 10 log (P) dB on all
              frequencies between the channel edge and 5 megahertz from the channel edge, 43 + 10 log (P) dB
              on all frequencies between 5 megahertz and X megahertz from the channel edge, and 55 + 10 log
              (P) dB on all frequencies more than X megahertz from the channel edge, where X is the greater of 6
              megahertz or the actual emission bandwidth as defined in paragraph (m)(6) of this section. In
              addition, the attenuation factor shall not be less that 43 + 10 log (P) dB on all frequencies between
              2490.5 MHz and 2496 MHz and 55 + 10 log (P) dB at or below 2490.5 MHz. Mobile Satellite Service
              licensees operating on frequencies below 2495 MHz may also submit a documented interference
              complaint against BRS licensees operating on channel BRS Channel 1 on the same terms and
              conditions as adjacent channel BRS or EBS licensees.

          (5) Notwithstanding the provisions of paragraphs (l)(2) and (l)(4) of this section, prior to transition, a
              licensee may continue to operate facilities deployed as of January 10, 2005 provided that such
              facilities operate in compliance with the emission mask applicable to those services prior to January
              10, 2005.

          (6) Measurement procedure. Compliance with these rules is based on the use of measurement
              instrumentation employing a resolution bandwidth of 1 megahertz or greater. However, in the 1 MHz
              bands immediately outside and adjacent to the frequency block a resolution bandwidth of at least
              one percent of the emission bandwidth of the fundamental emission of the transmitter may be
              employed; for mobile digital stations, in the 1 megahertz bands immediately outside and adjacent to
              the frequency block a resolution bandwidth of at least two percent may be employed, except when
              the 1 megahertz band is 2495–2496 MHz, in which case a resolution bandwidth of at least one
              percent may be employed. A narrower resolution bandwidth is permitted in all cases to improve
              measurement accuracy provided the measured power is integrated over the full required
              measurement bandwidth (i.e. 1 megahertz or 1 percent of emission bandwidth, as specified; or 1
              megahertz or 2 percent for mobile digital stations, except in the band 2495–2496 MHz). The
              emission bandwidth is defined as the width of the signal between two points, one below the carrier
              center frequency and one above the carrier center frequency, outside of which all emissions are
              attenuated at least 26 dB below the transmitter power. With respect to television operations,
              measurements must be made of the separate visual and aural operating powers at sufficiently
              frequent intervals to ensure compliance with the rules.

           (7) Alternative out of band emission limit. Licensees in this service may establish an alternative out of
               band emission limit to be used at specified band edge(s) in specified geographical areas, in lieu of
               that set forth in this section, pursuant to a private contractual arrangement of all affected licensees
               and applicants. In this event, each party to such contract shall maintain a copy of the contract in
               their station files and disclose it to prospective assignees or transferees and, upon request, to the
               FCC.

     (n) 3.45 GHz Service. The following emission limits apply to stations transmitting in the 3450–3550 MHz
         band:

           (1) For base station operations in the 3450–3550 MHz band, the conducted power of any emission
               outside the licensee's authorized bandwidth shall not exceed −13 dBm/MHz. Compliance with the
               provisions of this paragraph (n)(1) is based on the use of measurement instrumentation employing a
               resolution bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands immediately
               outside and adjacent to the licensee's frequency block, a resolution bandwidth of at least one
               percent of the emission bandwidth of the fundamental emission of the transmitter may be employed,
               but limited to a maximum of 200 kHz. The emission bandwidth is defined as the width of the signal
               between two points, one below the carrier center frequency and one above the carrier center
               frequency, outside of which all emissions are attenuated at least 26 dB below the transmitter power.
               Notwithstanding the channel edge requirement of −13 dBm per megahertz, for base station
               operations in the 3450–3550 MHz band, the conducted power of any emission below 3440 MHz or
               above 3560 MHz shall not exceed −25 dBm/MHz, and the conducted power of emissions below
               3430 MHz or above 3570 MHz shall not exceed −40 dBm/MHz.

           (2) For mobile operations in the 3450–3550 MHz band, the conducted power of any emission outside
               the licensee's authorized bandwidth shall not exceed −13 dBm/MHz. Compliance with this
               paragraph (n)(2) is based on the use of measurement instrumentation employing a resolution
               bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands immediately outside and
               adjacent to the licensee's frequency block, a resolution bandwidth of at least one percent of the
               emission bandwidth of the fundamental emission of the transmitter may be employed, but limited to
               a maximum of 200 kHz. In the bands between 1 and 5 MHz removed from the licensee's frequency
               block, the minimum resolution bandwidth for the measurement shall be 500 kHz. The emission
               bandwidth is defined as the width of the signal between two points, one below the carrier center
               frequency and one above the carrier center frequency, outside of which all emissions are attenuated
               at least 26 dB below the transmitter power.

     (o) When an emission outside of the authorized bandwidth causes harmful interference, the Commission
         may, at its discretion, require greater attenuation than specified in this section.

§ 27.55 Power strength limits.
     (a) Field strength limits. For the following bands, the predicted or measured median field strength at any
         location on the geographical border of a licensee's service area shall not exceed the value specified
         unless the adjacent affected service area licensee(s) agree(s) to a different field strength. This value
         applies to both the initially offered service areas and to partitioned service areas.

          (1) 1995–2000 MHz, 2110–2155, 2155–2180, 2180–2200, 2305–2320, and 2345–2360 MHz bands: 47
              dBµV/m.

          (2) 600 MHz, 698–758, and 775–787 MHz bands: 40 dBµV/m.

          (3) The paired 1392–1395 MHz and 1432–1435 MHz bands and the unpaired 1390–1392 MHz band
              (1.4 GHz band): 47 dBµV/m.

          (4) BRS and EBS: The predicted or measured median field strength at any location on the geographical
              border of a licensee's service area shall not exceed the value specified unless the adjacent affected
              service area licensee(s) agree(s) to a different field strength. This value applies to both the initially
              offered services areas and to partitioned services areas. Licensees may exceed this signal level
              where there is no affected licensee that is constructed and providing service. Once the affected
              licensee is providing service, the original licensee will be required to take whatever steps necessary
              to comply with the applicable power level at its GSA boundary, absent consent from the affected
              licensee.

                (i)   Prior to transition, the signal strength at any point along the licensee's GSA boundary does not
                      exceed the greater of that permitted under the licensee's Commission authorizations as of
                      January 10, 2005 or 47 dBµV/m.

                (ii) Following transition, for stations in the LBS and UBS, the signal strength at any point along the
                     licensee's GSA boundary must not exceed 47 dBµV/m. This field strength is to be measured at
                     1.5 meters above the ground over the channel bandwidth (i.e., each 5.5 MHz channel for
                     licensees that hold a full channel block, and for the 5.5 MHz channel for licensees that hold
                     individual channels).

                (iii) Following transition, for stations in the MBS, the signal strength at any point along the licensee's
                      GSA boundary must not exceed the greater of −73.0 + 10 log(X/6) dBW/m2, where X is the
                      bandwidth in megahertz of the channel, or for facilities that are substantially similar to the
                      licensee's pre-transition facilities (including modifications that do not alter the fundamental
                      nature or use of the transmissions), the signal strength at such point that resulted from the
                      station's operations immediately prior to the transition, provided that such operations complied
                      with paragraph (a)(4)(i) of this section.

     (b) Power flux density limit for stations operating in the 698–746 MHz bands. For base and fixed stations
         operating in the 698–746 MHz band in accordance with the provisions of § 27.50(c)(6), the power flux
         density that would be produced by such stations through a combination of antenna height and vertical
         gain pattern must not exceed 3000 microwatts per square meter on the ground over the area extending to
         1 km from the base of the antenna mounting structure.

         density (PFD) at any location on the geographical border of a licensee's service area shall not exceed −76
         dBm/m2/MHz. This power flux density will be measured at 1.5 meters above ground. Licensees in
         adjacent geographic areas may voluntarily agree to operate under a higher PFD at their common

§ 27.56 Antenna structures; air navigation safety.
A licensee that owns its antenna structure(s) must not allow such antenna structure(s) to become a hazard to air
navigation. In general, antenna structure owners are responsible for registering antenna structures with the FCC if
required by part 17 of this chapter, and for installing and maintaining any required marking and lighting. However, in
the event of default of this responsibility by an antenna structure owner, the FCC permittee or licensee authorized to
use an affected antenna structure will be held responsible by the FCC for ensuring that the antenna structure
continues to meet the requirements of part 17 of this chapter. See § 17.6 of this chapter.

     (a) Marking and lighting. Antenna structures must be marked, lighted and maintained in accordance with part
         17 of this chapter and all applicable rules and requirements of the Federal Aviation Administration. For
         any construction or alteration that would exceed the requirements of section 17.7 of this chapter,
         licensees must notify the appropriate Regional Office of the Federal Aviation Administration (FAA Form
         7460–1) and file a request for antenna height clearance and obstruction marking and lighting
         specifications (FCC Form 854) with the FCC, WTB, 1270 Fairfield Road, Gettysburg, PA 17325.

     (b) Maintenance contracts. Antenna structure owners (or licensees and permittees, in the event of default by
         an antenna structure owner) may enter into contracts with other entities to monitor and carry out
         necessary maintenance of antenna structures. Antenna structure owners (or licensees and permittees, in
         the event of default by an antenna structure owner) that make such contractual arrangements continue to
         be responsible for the maintenance of antenna structures in regard to air navigation safety.

§ 27.58 Interference to BRS/EBS receivers.
     (a) WCS licensees shall bear full financial obligation to remedy interference to BRS/EBS block
         downconverters if all of the following conditions are met:

           (1) The complaint is received by the WCS licensee prior to February 20, 2002;

           (2) The BRS/EBS downconverter was installed prior to August 20, 1998;

           (3) The WCS fixed or land station transmits at 50 or more watts peak EIRP;

           (4) The BRS/EBS downconverter is located within a WCS transmitter's free space power flux density
               contour of −34 dBW/m2; and

           (5) The BRS/EBS customer or licensee has informed the WCS licensee of the interference within one
               year from the initial operation of the WCS transmitter or within one year from any subsequent power
               increases at the WCS station.

     (b) Resolution of the complaint shall be at no cost to the complainant.

     (c) Two or more WCS licensees collocating their antennas on the same tower shall assume shared
         responsibility for remedying interference complaints within the area determined by paragraph (a)(4) of
         this section unless an offending station can be readily determined and then that station shall assume full
         financial responsibility.

     (d) If the WCS licensee cannot otherwise eliminate interference caused to BRS/EBS reception, then that
         licensee must cease operations from the offending WCS facility.

     (e) At least 30 days prior to commencing operations from any new WCS transmission site or with increased
         power from any existing WCS transmission site, a WCS licensee shall notify all BRS/EBS licensees in or
         through whose licensed service areas they intend to operate of the technical parameters of the WCS

§ 27.59 [Reserved]
§ 27.60 TV/DTV interference protection criteria.

Link to an amendment published at 89 FR 7243, Feb. 1, 2024.

Base, fixed, control, and mobile transmitters in the 698–758 MHz, 775–788 MHz, and 805–806 MHz frequency
bands must be operated only in accordance with the rules in this section to reduce the potential for interference to
public reception of the signals of existing TV and DTV broadcast stations transmitting on TV Channels 51 through
68.

     (a) D/U ratios. Licensees must choose site locations that are a sufficient distance from co-channel and
         adjacent channel TV and DTV stations, and/or must use reduced transmitting power or transmitting
         antenna height such that the following minimum desired signal-to-undesired signal ratios (D/U ratios) are
         met.

           (1) The minimum D/U ratio for co-channel stations is:

                 (i)   40 dB at the hypothetical Grade B contour (64 dBµV/m) (88.5 kilometers (55 miles)) of the TV
                       station;

                 (ii) For transmitters operating in the 698–746 MHz frequency band, 23 dB at the equivalent Grade B
                      contour (41 dBµV/m) (88.5 kilometers (55 miles)) of the DTV station; or

                (iii) For transmitters operating in the 746–758 MHz, 775–788 MHz, and 805–806 MHz frequency
                      bands, 17 dB at the equivalent Grade B contour (41 dBµV/m) (88.5 kilometers (55 miles)) of the
                      DTV station.

           (2) The minimum D/U ratio for adjacent channel stations is 0 dB at the hypothetical Grade B contour (64
               dBµV/m) (88.5 kilometers (55 miles)) of the TV station or −23 dB at the equivalent Grade B contour
               (41 dBµV/m) (88.5 kilometers (55 miles)) of the DTV station.

     (b) TV stations and calculation of contours. The methods used to calculate TV contours and antenna heights
         above average terrain are given in §§ 73.683 and 73.684 of this chapter. Tables to determine the
         necessary minimum distance from the 698–758 MHz, 775–788 MHz, and 805–806 MHz station to the
         TV/DTV station, assuming that the TV/DTV station has a hypothetical or equivalent Grade B contour of
         88.5 kilometers (55 miles), are located in § 90.309 of this chapter and labeled as Tables B, D, and E. The
         locations of existing and proposed TV/DTV stations during the period of transition from analog to digital
         TV service are given in part 73 of this chapter and in the final proceedings of MM Docket No. 87–268.

           (1) Licensees of stations operating within the ERP and HAAT limits of § 27.50 must select one of four
               methods to meet the TV/DTV protection requirements, subject to Commission approval:

                 (i)   Utilize the geographic separation specified in Tables B, D, and E of § 90.309 of this chapter, as
                       appropriate;

                 (ii) When station parameters are greater than those indicated in the tables, calculate geographic
                      separation in accordance with the required D/U ratios, as provided in paragraph (a) of this
                      section;

Miscellaneous Wireless Communications Services

                (iii) Submit an engineering study justifying the proposed separations based on the parameters of
                      the land mobile station and the parameters, including authorized and/or applied for facilities, of
                      the TV/DTV station(s) it is trying to protect; or,

                (iv) Obtain written concurrence from the applicable TV/DTV station(s). If this method is chosen, a
                     copy of the agreement must be submitted with the application.

           (2) The following is the method for geographic separations.

                 (i)   Base and fixed stations that operate in the 746–758 MHz and 775–787 MHz bands having an
                       antenna height (HAAT) less than 152 m. (500 ft.) shall afford protection to co-channel and
                       adjacent channel TV/DTV stations in accordance with the values specified in Table B (co-
                       channel frequencies based on 40 dB protection) and Table E (adjacent channel frequencies
                       based on 0 dB protection) in § 90.309 of this chapter. Base and fixed stations that operate in
                       the 698–746 MHz band having an antenna height (HAAT) less than 152 m. (500 ft.) shall afford
                       protection to adjacent channel DTV stations in accordance with the values specified in Table E
                       in § 90.309 of this chapter, shall afford protection to co-channel DTV stations by providing 23
                       dB protection to such stations' equivalent Grade B contour (41 dBµV/m), and shall afford
                       protection to co-channel and adjacent channel TV stations in accordance with the values
                       specified in Table B (co-channel frequencies based on 40 dB protection) and Table E (adjacent
                       channel frequencies based on 0 dB protection) in § 90.309 of this chapter. For base and fixed
                       stations having an antenna height (HAAT) between 152–914 meters (500–3,000 ft.) the
                       effective radiated power must be reduced below 1 kilowatt in accordance with the values
                       shown in the power reduction graph in Figure B in § 90.309 of this chapter. For heights of more
                       than 152 m. (500 ft.) above average terrain, the distance to the radio path horizon will be
                       calculated assuming smooth earth. If the distance so determined equals or exceeds the
                       distance to the hypothetical or equivalent Grade B contour of a co-channel TV/DTV station (i.e.,
                       it exceeds the distance from the appropriate Table in § 90.309 of this chapter to the relevant
                       TV/DTV station), an authorization will not be granted unless it can be shown in an engineering
                       study (see paragraph (b)(1)(iii) of this section) that actual terrain considerations are such as to
                       provide the desired protection at the actual Grade B contour (64 dBµV/m for TV and 41 dBµV/m
                       for DTV stations) or unless the effective radiated power will be further reduced so that,
                       assuming free space attenuation, the desired protection at the actual Grade B contour (64
                       dBµV/m for TV and 41 dBµV/m coverage contour for DTV stations) will be achieved. Directions
                       for calculating powers, heights, and reduction curves are listed in § 90.309 of this chapter for
                       land mobile stations. Directions for calculating coverage contours are listed in §§ 73.683
                       through 73.685 of this chapter for TV stations and in § 73.625 of this chapter for DTV stations.

                 (ii) Control, fixed, and mobile stations (including portables) that operate in the 787–788 MHz and
                      805–806 MHz bands and control and mobile stations (including portables) that operate in the
                      698–757 MHz and 776–787 MHz bands are limited in height and power and therefore shall
                      afford protection to co-channel and adjacent channel TV/DTV stations in the following manner:

                       (A) For control, fixed, and mobile stations (including portables) that operate in the 787–788
                           MHz and 805–806 MHz bands and control and mobile stations (including portables) that
                           operate in the 746–757 MHz and 776–787 MHz bands, co-channel protection shall be
                           afforded in accordance with the values specified in Table D (co-channel frequencies based
                           on 40 dB protection for TV stations and 17 dB for DTV stations) in § 90.309 of this
                           chapter.

Miscellaneous Wireless Communications Services

                      (B) For control and mobile stations (including portables) that operate in the 698–746 MHz
                          band, co-channel protection shall be afforded to TV stations in accordance with the values
                          specified in Table D (co-channel frequencies based on 40 dB protection) and to DTV
                          stations by providing 23 dB protection to such stations' equivalent Grade B contour (41
                          dBµV/m).

                      (C) For control, fixed, and mobile stations (including portables) that operate in the 787–788
                          MHz and 805–806 MHz bands and control and mobile stations (including portables) that
                          operate in the 698–757 MHz and 776–787 MHz bands, adjacent channel protection shall
                          be afforded by providing a minimum distance of 8 kilometers (5 miles) from all adjacent
                          channel TV/DTV station hypothetical or equivalent Grade B contours (adjacent channel
                          frequencies based on 0 dB protection for TV stations and −23 dB for DTV stations).

                      (D) Since control, fixed, and mobile stations may affect different TV/DTV stations than the
                          associated base or fixed station, particular care must be taken by applicants/licensees to
                          ensure that all appropriate TV/DTV stations are considered (e.g., a base station may be
                          operating within TV Channel 62 and the mobiles within TV Channel 67, in which case TV
                          Channels 61, 62, 63, 66, 67 and 68 must be protected). Control, fixed, and mobile stations
                          shall keep a minimum distance of 96.5 kilometers (60 miles) from all adjacent channel
                          TV/DTV stations. Since mobiles and portables are able to move and communicate with
                          each other, licensees must determine the areas where the mobiles can and cannot roam in
                          order to protect the TV/DTV stations.

           Note to § 27.60: The 88.5 km (55mi) Grade B service contour (64 dBµV/m) is based on a
           hypothetical TV station operating at an effective radiated power of one megawatt, a transmitting
           antenna height above average terrain of 610 meters (2000 feet) and the Commission's R–6602
           F(50,50) curves. See § 73.699 of this chapter. Maximum facilities for TV stations operating in the
           UHF band are 5 megawatts effective radiated power at an antenna HAAT of 610 meters (2,000
           feet). See § 73.614 of this chapter. The equivalent contour for DTV stations is based on a 41
           dBµV/m signal strength and the distance to the F(50,90) curve. See § 73.625 of this chapter.

§ 27.64 Protection from interference.
Wireless Communications Service (WCS) stations operating in full accordance with applicable FCC rules and the
terms and conditions of their authorizations are normally considered to be non-interfering. If the FCC determines,
however, that interference which significantly interrupts or degrades a radio service is being caused, it may, after
notice and an opportunity for a hearing, require modifications to any WCS station as necessary to eliminate such
interference.

     (a) Failure to operate as authorized. Any licensee causing interference to the service of other stations by
         failing to operate its station in full accordance with its authorization and applicable FCC rules shall
         discontinue all transmissions, except those necessary for the immediate safety of life or property, until it
         can bring its station into full compliance with the authorization and rules.

     (b) Intermodulation interference. Licensees should attempt to resolve such interference by technical means.

     (c) Situations in which no protection is afforded. Except as provided elsewhere in this part, no protection from
         interference is afforded in the following situations:

           (1) Interference to base receivers from base or fixed transmitters. Licensees should attempt to resolve
               such interference by technical means or operating arrangements.

           (2) Interference to mobile receivers from mobile transmitters. No protection is provided against mobile-
               to-mobile interference.

           (3) Interference to base receivers from mobile transmitters. No protection is provided against mobile-to-
               base interference.

           (4) Interference to fixed stations. Licensees should attempt to resolve such interference by technical
               means or operating arrangements.

           (5) Anomalous or infrequent propagation modes. No protection is provided against interference caused
               by tropospheric and ionospheric propagation of signals.

     (d) Harmful interference to SDARS operations requiring resolution. The following conditions will be presumed
         to constitute harmful interference to SDARS operations from WCS operations in the 2305–2320 MHz and
         2345–2360 MHz bands and require WCS operators to work cooperatively with SDARS operators to
         address areas where such power levels are exceeded and harmful interference occurs:

           (1) A WCS ground signal level greater than −44 dBm in the upper or lower A or B block, or −55 dBm in the
               C or D block, present at a location on a roadway, where a test demonstrates that SDARS service
               would be muted over a road distance of greater than 50 meters; or

           (2) A WCS ground signal level exceeding −44 dBm in the upper or lower A or B block, or −55 dBm in the
               C or D block on a test drive route, which is mutually agreed upon by the WCS licensee and the SDARS
               licensee, for more than 1 percent of the cumulative surface road distance on that drive route, where
               a test demonstrates that SDARS service would be muted over a cumulative road distance of greater
               than 0.5 percent (incremental to any muting present prior to use of WCS frequencies in the area of
               that drive test).

     (a) Receivers operating in the 2000–2020 MHz band must accept interference from lawful operations in the
         1995–2000 MHz band, where such interference is due to:

           (1) The in-band power of any operations in 1995–2000 MHz (i.e., the portion transmit power contained
               in the 1995–2000 MHz band); or

§ 27.70 Information exchange.
     (a) Prior notification. Public safety licensees authorized to operate in the 758–775 MHz and 788–805 MHz
         bands may notify any licensee authorized to operate in the 746–757 or 776–787 MHz bands that they
         wish to receive prior notification of the activation or modification of the licensee's base or fixed stations in
         their area. Thereafter, the 746–757 or 776–787 MHz band licensee must provide the following
         information to the public safety licensee at least 10 business days before a new base or fixed station is
         activated or an existing base or fixed station is modified:

           (1) Location;

           (2) Effective radiated power;

           (3) Antenna height; and

           (4) Channels available for use.

     (b) Purpose of prior notification. The prior coordination of base or fixed stations is for informational purposes
         only. Public safety licensees are not afforded the right to accept or reject the activation of a proposed
         base or fixed station or to unilaterally require changes in its operating parameters. The principal purposes
         of notification are to:

           (1) Allow a public safety licensee to advise the 746–757 or 776–787 MHz band licensee whether it
               believes a proposed base or fixed station will generate unacceptable interference;

           (2) Permit 746–757 and 776–787 MHz band licensees to make voluntary changes in base or fixed
               station parameters when a public safety licensee alerts them to possible interference; and,

           (3) Rapidly identify the source if interference is encountered when the base or fixed station is activated.

§ 27.72 Information sharing requirements.
This section requires WCS licensees in the 2305–2320 MHz and 2345–2360 MHz bands to share information
regarding the location and operation of base and fixed stations (except fixed customer premises equipment) with
Satellite Digital Audio Radio Service (SDARS) licensees in the 2320–2345 MHz band. Section 25.263 of this chapter
requires SDARS licensees in the 2320–2345 MHz band to share information regarding the location and operation of
terrestrial repeaters with WCS licensees in the 2305–2320 MHz and 2345–2360 MHz bands. WCS licensees are
encouraged to develop separate coordination agreements with SDARS licensees to facilitate efficient deployment of
and coexistence between each service. To the extent the provisions of any such coordination agreement conflict
with the requirements set forth herein, the procedures established under a coordination agreement will control.
WCS licensees must maintain a copy of any coordination agreement with an SDARS licensee in their station files
and disclose it to prospective assignees, transferees, or spectrum lessees and, upon request, to the Commission.

     (a) Sites and frequency selections. WCS licensees must select base and fixed station sites and frequencies,
         to the extent practicable, to minimize the possibility of harmful interference to operations in the SDARS
         2320–2345 MHz band.

     (b) Prior notice periods. WCS licensees that intend to operate a base or fixed station must, before
         commencing such operation, provide 10 business days prior notice to all SDARS licensees. WCS
         licensees that intend to modify an existing station must, before commencing such modified operation,
         provide 5 business days prior notice to all SDARS licensees. For the purposes of this section, a business
         day is defined by § 1.4(e)(2) of this chapter.

           (1) For modifications other than changes in location, a licensee may provide notice within 24 hours after
               the modified operation if the modification does not result in a predicted increase of the power flux
               density (PFD) at ground level by more than 1 dB since the last advance notice was given. If a
               demonstration is made by the SDARS licensee that such modifications may cause harmful
               interference to SDARS receivers, WCS licensees will be required to provide notice 5 business days in
               advance of additional station modifications.

           (2) WCS base and fixed stations operating below 2 watts equivalent isotropically radiated power (EIRP)
               are exempt from the notice requirements set forth in this paragraph.

           (3) WCS and SDARS licensees may enter into agreements regarding alternative notification procedures.

     (c) Contents of notice.

           (1) Notification must be written (e.g., certified letter, fax, or e-mail) and include the licensee's name, and
               the name, address, and telephone number of its coordination representative, unless the SDARS
               licensee and all potentially affected WCS licensees reach a mutual agreement to provide notification
               by some other means. WCS licensees and SDARS licensees may establish such a mutually
               agreeable alternative notification mechanism without prior Commission approval, provided that they
               comply with all other requirements of this section.

           (2) Regardless of the notification method, it must specify relevant technical details, including, at a
               minimum:

                 (i)   The coordinates of the proposed base or fixed stations to an accuracy of no less than ±1
                       second latitude and longitude;

Miscellaneous Wireless Communications Services

                (ii) The proposed operating power(s), frequency band(s), and emission(s);

                (iii) The antenna center height above ground and ground elevation above mean sea level, both to an
                      accuracy of no less than ±1 meter;

                (iv) The antenna gain pattern(s) in the azimuth and elevation planes that include the peak of the
                     main beam; and

                (v) The antenna downtilt angle(s).

           (3) A WCS licensee operating base or fixed stations must maintain an accurate and up-to-date inventory
               of its stations, including the information set forth in § 27.72(c)(2), which shall be available upon
               request by the Commission.

     (d) Calculation of notice period. Notice periods are calculated from the date of receipt by the licensee being
         notified. If notification is by mail, the date of receipt is evidenced by the return receipt on certified mail. If
         notification is by fax, the date of receipt is evidenced by the notifying party's fax transmission
         confirmation log. If notification is by e-mail, the date of receipt is evidenced by a return e-mail receipt. If
         the SDARS licensee and all potentially affected WCS licensees reach a mutual agreement to provide
         notification by some other means, that agreement must specify the method for determining the beginning
         of the notice period.

     (e) Duty to cooperate. WCS licensees must cooperate in good faith in the selection and use of new station
         sites and new frequencies to reduce interference and make the most effective use of the authorized
         facilities. WCS licensees should provide SDARS licensees as much lead time as practicable to provide
         ample time to conduct analyses and opportunity for prudent base station site selection prior to WCS
         licensees entering into real estate and tower leasing or purchasing agreements. WCS licensees must have
         sufficient operational flexibility in their network design to implement one or more technical solutions to
         remedy harmful interference. Licensees of stations suffering or causing harmful interference, as defined
         in § 27.64(d), must cooperate in good faith and resolve such problems by mutually satisfactory
         arrangements. If the licensees are unable to do so, the Wireless Telecommunications Bureau, in
         consultation with the Office of Engineering and Technology and the Space Bureau, will consider the
         actions taken by the parties to mitigate the risk of and remedy any alleged interference. In determining the
         appropriate action, the Bureau will take into account the nature and extent of the interference and act
         promptly to remedy the interference. The Bureau may impose restrictions on WCS licensees, including
         specifying the transmitter power, antenna height, or other technical or operational measures to remedy
         the interference, and will take into account previous measures by the licensees to mitigate the risk of
         interference.

Miscellaneous Wireless Communications Services

     (a) WCS licensees operating base and fixed stations in the 2345–2360 MHz band must, prior to operation of
         such stations, achieve a mutually satisfactory coordination agreement with the AMT entity(ies) (i.e., FCC
         licensee(s) and/or Federal operator(s)) for any AMT receiver facility within 45 kilometers or radio line of
         sight, whichever distance is larger, of the intended WCS base or fixed station location. The coordinator for
         the assignment of flight test frequencies in the 2360–2390 MHz band, Aerospace and Flight Test Radio
         Coordination Council (AFTRCC) or successors of AFTRCC, will facilitate a mutually satisfactory
         coordination agreement between the WCS licensee(s) and AMT entity(ies) for existing AMT receiver sites.
         The locations of current Federal and non-Federal AMT receiver sites may be obtained from AFTRCC at
         Post Office Box 12822 Wichita, KS 67277–2822, (316) 946–8826, or successor frequency coordinators of
         AFTRCC. Such coordination agreement shall provide protection to existing AMT receiver stations
         consistent with International Telecommunication Union (ITU) Recommendation ITU–R M.1459,
         “Protection criteria for telemetry systems in the aeronautical mobile service and mitigation techniques to
         facilitate sharing with geostationary broadcasting-satellite and mobile-satellite services in the frequency

     (b) WCS licensees operating base and fixed stations in the 2305–2320 MHz band must, prior to operation of
         such stations, achieve a mutually satisfactory coordination agreement with the National Aeronautics and
         Space Administration (NASA) within 145 kilometers of the Goldstone, CA earth station site (35°25′33″ N,
         116°53′23″ W).

     (c) After base or fixed station operations commence, upon receipt of a complaint of harmful interference, the
         WCS licensee(s) receiving the complaint, no matter the distance from the NASA Goldstone, CA earth
         station or from an AMT site, operating in the 2305–2320 or 2345–2360 MHz bands, respectively, shall
         take all practicable steps to immediately eliminate the interference.

     (d) Duty to cooperate. WCS licensees, AFTRCC, and NASA must cooperate in good faith in the coordination
         and deployment of new facilities. WCS licensees must also cooperate in good faith in the selection and
         use of new station sites and new frequencies when within radio line of site of AMT receiver facilities to
         reduce the risk of harmful interference and make the most effective use of the authorized facilities.
         Licensees of stations suffering or causing harmful interference must cooperate in good faith and resolve
         such problems by mutually satisfactory arrangements. If the licensees are unable to do so, the Wireless
         Telecommunications Bureau, in consultation with the Office of Engineering and Technology and the
         National Telecommunications and Information Administration may impose restrictions including
         specifying the transmitter power, antenna height, or area or hours of operation of the stations.

           (v) A description of the area served and the operator's name.

                (2) It is the CMRS operator's responsibility to determine whether referral is required for stations
                constructed in its area of license. Public safety base stations are considered “planned” when public
                safety operators have notified, or initiated coordination with, a Commission-approved public safety
                coordinator.

     (b) CMRS operators must wait at least 10 business days after submission of the required description before
         commencing operations on the referenced facility, or implementing modifications to an existing facility.

     (c) The potential for harmful interference between the CMRS and public safety facilities will be evaluated by
         the public safety coordinator.

           (1) With regard to existing public safety facilities, the coordinator's determination to disapprove a
           proposed CMRS facility (or modification) to be located within 500 meters of the public safety facilities will
           be presumed correct, but the CMRS operator may seek Commission review of such determinations.
           Pending Commission review, the CMRS operator will not activate the facility or implement proposed
           modifications.

           (2) With regard to proposed public safety facilities, the coordinator's determination to disapprove a
           proposed CMRS facility (or modification) to be located within 500 meters of the public safety facilities will
           be presumed correct, but the CMRS operator may seek Commission review and, pending completion of
           review, operate the facility during construction of the public safety facilities. If coordination or
           Commission review has not been completed when the public safety facilities are ready to operate, the
           CMRS operator must cease operations pending completion of coordination or Commission review. Such
           interim operation of the CMRS facility within the coordination zone (or implementation of modifications)

            REIMBURSEMENT OBLIGATION OF LICENSEES AT 1915–1920 MHZ AND 1995–2000 MHZ

§ 27.1021 Reimbursement obligation of licensees at 1915–1920 MHz.
A licensee in the 1915–1920 MHz band (Lower H Block) shall, within 30 days of grant of its long-form application,
reimburse 25 percent of the total relocation costs incurred by UTAM, Inc. for relocating and clearing incumbent
Fixed Microwave Service (FS) licensees from the 1910–1930 MHz band on a pro rata shared basis with other Lower
H Block licensees as set forth in paragraphs (a) through (e) of this section.

     (a)

           (1) If Lower H Block licenses granted as a result of the first auction for this spectrum cover, collectively,
               at least forty (40) percent of the nation's population, the amount owed to UTAM, Inc. by each
               individual Lower H Block licensee (reimbursement amount owed or RN) will be determined by
               dividing the gross winning bid (GWB) for each individual Lower H Block license (i.e., an Economic
               Area (EA)) by the sum of the gross winning bids for all Lower H Block licenses for which there is a
               winning bid in the first auction, and then multiplying by $12,629,857.

                RN = (EA GWB ÷ Sum of GWBs) × $12,629,857.00
           (2) Except as provided in paragraphs (b) and (c) of this section, a licensee that obtains a license for a
               market in which no license is granted as a result of the first Lower H Block auction will not have a
               reimbursement obligation to UTAM, Inc.

     (b) If Lower H Block licenses granted as a result of the first auction for this spectrum cover, collectively, less
         than forty (40) percent of the nation's population, then the pro rata amount that the licensee of an
         individual Lower H Block license must reimburse UTAM, Inc. shall be calculated by dividing the population
         of the individual EA by the total U.S. population, and then multiplying by $12,629,857. In this event, the
         same population data, e.g., 2010, used to calculate the RNs for Lower H Block licenses granted as a result
         of the first auction will apply to subsequent auctions of Lower H Block licenses that were not granted as a
         result of an earlier auction of Lower H Block licenses.

           RN = (EA POP ÷ U.S. POP) × $12,629,857.00

Miscellaneous Wireless Communications Services

     (c) A winning bidder of a Lower H Block license that is not granted a license for any reason will be deemed to
         have triggered a reimbursement obligation to UTAM, Inc. This obligation will be owed to UTAM, Inc. by the
         licensee acquiring the Lower H Block license through a subsequent auction. The amount owed by the
         licensee acquiring the Lower H Block license at such auction will be the RN calculated for the EA license
         based on the first auction (calculated under paragraphs (a) or (b), as applicable, of this section).

     (d) For purposes of compliance with this section, licensees should determine population based on 2010 U.S.
         Census Data or such other data or measurements that the Wireless Telecommunications Bureau
         proposes and adopts under the notice and comment process for the auction procedures.

     (e) A payment obligation owed by a Lower H Block licensees under this section shall be made within thirty
         (30) days of the grant of the license (i.e., grant of the long form application).

§ 27.1031 Reimbursement obligation of licensees at 1995–2000 MHz.
A licensee in the 1995–2000 MHz band (Upper H Block) shall, within 30 days of grant of its long-form application,
reimburse one-seventh of the eligible expenses incurred by Sprint Nextel, Inc. (Sprint) for relocating and clearing
Broadcast Auxiliary Service (BAS), Cable Television Relay Service (CARS), and Local Television Transmission
Service (LTTS) incumbents from the 1990–2025 MHz band, on a pro rata shared basis with other Upper H Block
licensees as set forth in paragraphs (a) through (e) of this section.

     (a)

           (1) If Upper H Block licenses granted as a result of the first auction for this spectrum cover, collectively,
               at least forty (40) percent of the nation's population, the amount owed to Sprint by the winning bidder
               of each individual Upper H Block license granted as a result of the first auction will be determined by
               dividing the gross winning bid (GWB) for each individual Upper H Block license (i.e., an Economic
               Area (EA)) by the sum of the gross winning bids for all Upper H Block licenses for which there is a
               winning bid in the first auction, and then multiplying by $94,875,516.

                RN = (EA GWB ÷ Sum of GWBs) × $94,875,516
           (2) Except as provided in paragraphs (b) and (c) of this section, a licensee that obtains a license for a
               market in which no license was granted as a result of the first Upper H Block auction will not have a
               reimbursement obligation to Sprint.

     (b) If Upper H Block licenses granted as a result of the first auction for this spectrum cover, collectively, less
         than forty (40) percent of the nation's population, then the amount that the licensee of an individual Upper
         H Block license must reimburse Sprint shall be calculated by dividing the population of the individual EA
         by the total U.S. population, and then multiplying by $94,875,516. In this event, the same population data,
         e.g., 2010, used to calculate the RNs for Upper H Block licenses granted as a result of the first auction will
         apply to subsequent auctions of Upper H Block licenses that were not granted as a result of an earlier
         auction of Upper H Block licenses.

           RN = (EA POP ÷ U.S. POP) × $94,875,516
     (c) A winning bidder of an Upper H Block license that is not granted a license for any reason will be deemed
         to have triggered a reimbursement obligation to Sprint. This obligation will be owed to Sprint by the
         licensee acquiring the Upper H Block license through a subsequent auction. The amount owed by the
         licensee acquiring the EA license at such auction will be based on the RN calculated for the EA license
         based on the first auction (calculated under paragraphs (a) or (b), as applicable, of this section).

§ 27.1134 Protection of Federal Government operations.
     (a) Protection of Department of Defense operations in the 1710–1755 MHz band. The Department of Defense
         (DoD) operates communications systems in the 1710–1755 MHz band at 16 protected facilities,
         nationwide. AWS licensees must accept any interference received from these facilities and must protect
         the facilities from interference. AWS licensees shall protect the facilities from interference by restricting
         the operation of their base and fixed stations from any locations that could potentially permit AWS mobile,
         fixed, and portable stations transmitting in the 1710–1755 MHz band to cause interference to government
         operations within the radii of operation of the 16 facilities (the radii of operation of each facility is
         indicated in the third column of Table 1 immediately following paragraph (a)(3) of this section). In
         addition, AWS licensees shall be required to coordinate any operations that could permit mobile, fixed, and
         portable stations to operate in the specified areas of the 16 facilities, as defined in paragraph (a)(3) of this
         section. Protection of these facilities in this manner shall take place under the following conditions:

          (1) At the Yuma, Arizona and Cherry Point, North Carolina facilities, all operations shall be protected
              indefinitely.

          (2) At the remaining 14 facilities, airborne and military test range operations shall be protected until such
              time as these systems are relocated to other spectrum, and precision guided munitions (PGM)
              operations shall be protected until such time as these systems are relocated to other spectrum or
              until PGM inventory at each facility is exhausted, whichever occurs first.

          (3) AWS licensees whose transmit operations in the 1710–1755 MHz band consist of fixed or mobile
              operations with nominal transmit EIRP values of 100 mW or less and antenna heights of 1.6 meters
              above ground or less shall coordinate their services around the 16 sites at the distance specified in
              row a. of Table 2. AWS licensees whose transmit operations in the 1710–1755 MHz band consist of
              fixed or mobile operations with nominal transmit EIRP values of 1 W or less and antenna heights of
              10 meters above ground or less shall coordinate their services around the 16 sites at the distance
              specified in row b. of Table 2. These coordination distances shall be measured from the edge of the
              operational distances indicated in the third column of Table 1, and coordination with each affected

     (b) Protection of non-DoD operations in the 1710–1755 MHz and 1755–1761 MHz bands. Until such time as
         non-DoD systems operating in the 1710–1755 MHz and 1755–1761 MHz bands are relocated to other
         spectrum, AWS licensees shall protect such systems by satisfying the appropriate provisions of TIA
         Telecommunications Systems Bulletin 10–F, “Interference Criteria for Microwave Systems,” May, 1994
         (TSB 10–F).

     (c) Protection of Federal operations in the 1675–1710 MHz band —

          (1) 27 Protection Zones. Within 27 Protection Zones, prior to operating a base station that enables
              mobile or portable stations to transmit in the 1695–1710 MHz band, licensees must successfully
              coordinate such base station operations with Federal Government entities operating meteorological
              satellite Earth-station receivers in the 1675–1710 MHz band. See 47 CFR 2.106, footnote US 88, for
              the 27 Protection Zones and other details.

          (2) Operation outside of 27 Protection Zones. Non-Federal operations, for mobile and portable stations
              operating at a maximum EIRP of 20 dBm, are permitted outside of the protection zones without
              coordination. All non-Federal operations for mobile and portables operating at a maximum EIRP of
              greater than 20 dBm and up to 30 dBm must be coordinated nationwide. All such operations may not
              cause harmful interference to the Federal operations protected in 47 CFR 2.106, footnote US 88.

          (3) Interference. If protected Federal operations receive harmful interference from AWS operations in the
              1695–1710 MHz band, an AWS licensee must, upon notification, modify its operations and/or
              technical parameters as necessary to eliminate the interference.

          (4) Point of contact. AWS licensees in the 1695–1710 MHz band must provide and maintain a point of
              contact at all times so that immediate contact can be made should interference against protected
              Federal sites occur.

Miscellaneous Wireless Communications Services

          (5) Coordination procedures. Federal use of the radio spectrum is generally governed by the National
              Telecommunications and Information Administration (NTIA) while non-Federal use is governed by
              the Commission. As such, any guidance or details concerning Federal/non-Federal coordination
              must be issued jointly by NTIA and the Commission. The Commission may jointly issue with NTIA
              one or more public notices with guidance or details concerning the coordination procedures for the
              1695–1710 MHz band.

          (6) Requirements for licensees operating in the 1710–1755 MHz band. AWS licensees operating fixed
              stations in the 1710–1755 MHz band, if notified that such stations are causing interference to
              radiosonde receivers operating in the Meteorological Aids Service in the 1675–1700 MHz band or a
              meteorological-satellite earth receiver operating in the Meteorological-Satellite Service in the
              1675–1710 MHz band, shall be required to modify the stations' location and/or technical parameters
              as necessary to eliminate the interference.

     (d) Recognition of NASA Goldstone facility operations in the 2110–2120 MHz band. The National Aeronautics
         and Space Administration (NASA) operates the Deep Space Network (DSN) in the 2110–2120 MHz band
         at Goldstone, California (see Table 3). NASA will continue its operations of high power transmitters
         (nominal EIRP of 105.5 dBW with EIRP up to 119.5 dBW used under emergency conditions) in this band at
         this location. AWS licensees must accept any interference received from the Goldstone DSN facility in this
         band.

     (e) Protection of Federal operations in the 2200–2290 MHz band —

          (1) Default emission limits. Except as provided in paragraph (e)(2) of this section, the following default
              out-of-band emissions limits shall apply for AWS–4 operations in the 2180–2200 MHz band.

                (i)   For these AWS–4 operations, the power of any emissions on all frequencies between 2200 and
                      2290 MHz shall not exceed an EIRP of −100.6 dBW/4 kHz.

                (ii) No AWS–4 base station operating in the 2180–2200 MHz band shall be located less than 820
                     meters from a U.S. Earth Station facility operating in the 2200–2290 MHz band.

          (2) Agreements between AWS–4 operators and Federal government entities. The out-of-band emissions
              limits in paragraph (e)(1) of this section may be modified by the private contractual agreement of
              licensees of AWS–4 operating authority and Federal government entities operating in the
              2200–2290 MHz band. Such agreement shall be transmitted to the Commission by the National
              Telecommunications and Information Administration (NTIA) of the U.S. Department of Commerce. A
              licensee of AWS–4 operating authority who is a party to such an agreement must maintain a copy of
              the agreement in its station files and disclose it, upon request, to prospective AWS–4 assignees,
              transferees, or spectrum lessees, to Federal operators, and to the Commission.

Miscellaneous Wireless Communications Services

     (f) Protection of Federal operations in the 1755–1780 MHz band. The Federal Government operates
         communications systems in the 1755–1780 MHz band. Certain systems are expected to continue to
         operate in the band indefinitely. All other operations will be relocating to other frequencies or otherwise
         cease operations in the 1755–1780 MHz band in accordance with 47 CFR part 301. Until such a time as
         Federal operations in the 1755–1780 MHz bands vacate this spectrum, AWS licensees shall protect such
         systems and must accept any interference received from these Federal operations. See 47 CFR 2.106,
         footnote US 91, for details. AWS licensees must successfully coordinate proposed operations with all
         Federal incumbents prior to operation as follows:

           (1) Protection Zone(s). A protection zone is established for each Federal operation pursuant to 47 CFR
               2.106, footnote US 91. Unless otherwise specified in later Commission actions, the default
               protection zone is nationwide. A base station which enables mobile or portable stations to transmit
               in the 1755–1780 MHz band may not operate within the Protection Zone(s) of a Federal operation
               until the licensee successfully coordinates such base station operations with Federal Government
               entities as follows depending on the type of Federal incumbent authorization:

                 (i)   Federal US&P Assignments. Each AWS licensee must coordinate with each Federal agency that
                       has U.S. and Possessions (US&P) authority prior to its first operations in its licensed area to
                       reach a coordination arrangement with each US&P agency on an operator-to-operator basis.
                       (Agencies with U.S. and Possessions (US&P) authority do not operate nationwide and may be
                       able to share, prior to relocation, in some areas.)

                (ii) Other Federal Assignments. Each AWS licensee must successfully coordinate all base station
                     operations within a Protection Zone with the Federal incumbents. The default requirement is a
                     nationwide coordination zone with possible revisions to the Protection Zone and other details
                     to be announced in a Joint FCC/NTIA public notice.

           (2) Interference. If protected Federal operations receive harmful interference from AWS operations in the
               1755–1780 MHz band, an AWS licensee must, upon notification, modify its operations and/or
               technical parameters as necessary to eliminate the interference.

           (3) Point of contact. AWS licensees in the 1755–1780 MHz band must provide and maintain a point of
               contact at all times so that immediate contact can be made should interference against protected
               Federal operations occur.

           (4) Coordination procedures. Federal use of the radio spectrum is generally governed by the National
               Telecommunications and Information Administration (NTIA) while non-Federal use is governed by
               the Commission. As such, any guidance or details concerning Federal/non-Federal coordination
               must be issued jointly by NTIA and the Commission. The Commission may jointly issue with NTIA
               one or more public notices with guidance or details concerning the coordination procedures for the
               1755–1780 MHz band.

§ 27.1160 Cost-sharing requirements for AWS.
Frequencies in the 2110–2150 MHz and 2160–2200 MHz bands listed in § 101.147 of this chapter have been
reallocated from Fixed Microwave Services (FMS) to use by AWS (as reflected in § 2.106 of this chapter). In
accordance with procedures specified in § 22.602 and §§ 101.69 through 101.82 of this chapter, AWS entities are
required to relocate the existing microwave licensees in these bands if interference to the existing microwave
licensee would occur. All AWS entities that benefit from the clearance of this spectrum by other AWS entities or by a
voluntarily relocating microwave incumbent must contribute to such relocation costs. AWS entities may satisfy their
reimbursement requirement by entering into private cost-sharing agreements or agreeing to terms other than those
specified in § 27.1164. However, AWS entities are required to reimburse other AWS entities or voluntarily relocating
microwave incumbents that incur relocation costs and are not parties to the alternative agreement. In addition,
parties to a private cost-sharing agreement may seek reimbursement through the clearinghouse (as discussed in §
27.1162) from AWS entities or other Emerging Technologies (ET) entities, including Mobile Satellite Service (MSS)
operators (for Ancillary Terrestrial Component (ATC) base stations), that are not parties to the agreement. The cost-
sharing plan is in effect during all phases of microwave relocation specified in §§ 22.602 and 101.69 of this
chapter. If an AWS licensee enters into a spectrum leasing arrangement (as set forth in part 1, subpart X of this
chapter) and the spectrum lessee triggers a cost-sharing obligation, the licensee is the AWS entity responsible for

The Wireless Telecommunications Bureau, under delegated authority, will select one or more entities to operate as a
neutral, not-for-profit clearinghouse(s). This clearinghouse(s) will administer the cost-sharing plan by, inter alia,
determining the cost-sharing obligation of AWS and other ET entities for the relocation of FMS incumbents from the
2110–2150 MHz and 2160–2200 MHz bands. The clearinghouse filing requirements (see §§ 27.1166(a), 27.1170)

§ 27.1164 The cost-sharing formula.
An AWS relocator who relocates an interfering microwave link, i.e., one that is in all or part of its market area and in
all or part of its frequency band or a voluntarily relocating microwave incumbent, is entitled to pro rata
reimbursement based on the following formula:

     (a) RN equals the amount of reimbursement.

     (b) C equals the actual cost of relocating the link(s). Actual relocation costs include, but are not limited to,
         such items as: Radio terminal equipment (TX and/or RX—antenna, necessary feed lines, MUX/Modems);
         towers and/or modifications; back-up power equipment; monitoring or control equipment; engineering
         costs (design/path survey); installation; systems testing; FCC filing costs; site acquisition and civil works;
         zoning costs; training; disposal of old equipment; test equipment (vendor required); spare equipment;
         project management; prior coordination notification under § 101.103(d) of this chapter; site lease
         renegotiation; required antenna upgrades for interference control; power plant upgrade (if required);
         electrical grounding systems; Heating Ventilation and Air Conditioning (HVAC) (if required); alternate
         transport equipment; and leased facilities. Increased recurring costs represent part of the actual cost of
         relocation and, even if the compensation to the incumbent is in the form of a commitment to pay five
         years of charges, the AWS or MSS/ATC relocator is entitled to seek immediate reimbursement of the lump
         sum amount based on present value using current interest rates, provided it has entered into a legally
         binding agreement to pay the charges. C also includes voluntarily relocating microwave incumbent's
         independent third party appraisal of its compensable relocation costs and incumbent transaction
         expenses that are directly attributable to the relocation, subject to a cap of two percent of the “hard” costs
         involved. Hard costs are defined as the actual costs associated with providing a replacement system,
         such as equipment and engineering expenses. C may not exceed $250,000 per paired link, with an
         additional $150,000 permitted if a new or modified tower is required.

     (c) N equals the number of AWS and MSS/ATC entities that have triggered a cost-sharing obligation. For the
         AWS relocator, N = 1. For the next AWS entity triggering a cost-sharing obligation, N = 2, and so on. In the
         case of a voluntarily relocating microwave incumbent, N = 1 for the first AWS entity triggering a cost-
         sharing obligation. For the next AWS or MSS/ATC entity triggering a cost-sharing obligation, N = 2, and so
         on.

     (d) Tm equals the number of months that have elapsed between the month the AWS or MSS/ATC relocator or
         voluntarily relocating microwave incumbent obtains reimbursement rights for the link and the month in
         which an AWS entity triggers a cost-sharing obligation. An AWS or MSS/ATC relocator obtains
         reimbursement rights for the link on the date that it signs a relocation agreement with a microwave

          incumbent. A voluntarily relocating microwave incumbent obtains reimbursement rights for the link on the
          date that the incumbent notifies the Commission that it intends to discontinue, or has discontinued, the
          use of the link, pursuant to § 101.305 of the Commission's rules.

§ 27.1166 Reimbursement under the Cost-Sharing Plan.
     (a) Registration of reimbursement rights. Claims for reimbursement under the cost-sharing plan are limited to
         relocation expenses incurred on or after the date when the first AWS license is issued in the relevant AWS
         band (start date). If a clearinghouse is not selected by that date (see § 27.1162) claims for
         reimbursement (see § 27.1166) and notices of operation (see § 27.1170) for activities that occurred after
         the start date but prior to the clearinghouse selection must be submitted to the clearinghouse within 30
         calendar days of the selection date.

          (1) To obtain reimbursement, an AWS relocator must submit documentation of the relocation agreement
              to the clearinghouse within 30 calendar days of the date a relocation agreement is signed with an
              incumbent. In the case of involuntary relocation, an AWS relocator must submit documentation of
              the relocated system within 30 calendar days after the end of the relocation.

          (2) To obtain reimbursement, a voluntarily relocating microwave incumbent must submit documentation
              of the relocation of the link to the clearinghouse within 30 calendar days of the date that the
              incumbent notifies the Commission that it intends to discontinue, or has discontinued, the use of the
              link, pursuant to § 101.305 of the Commission's rules.

     (b) Documentation of expenses. Once relocation occurs, the AWS relocator, or the voluntarily relocating
         microwave incumbent, must submit documentation itemizing the amount spent for items specifically
         listed in § 27.1164(b), as well as any reimbursable items not specifically listed in § 27.1164(b) that are
         directly attributable to actual relocation costs. Specifically, the AWS relocator, or the voluntarily relocating
         microwave incumbent must submit, in the first instance, only the uniform cost data requested by the
         clearinghouse along with a copy, without redaction, of either the relocation agreement, if any, or the third
         party appraisal described in (b)(1) of this section, if relocation was undertaken by the microwave
         incumbent. AWS relocators and voluntarily relocating microwave incumbents must maintain
         documentation of cost-related issues until the applicable sunset date and provide such documentation
         upon request, to the clearinghouse, the Commission, or entrants that trigger a cost-sharing obligation. If
         an AWS relocator pays a microwave incumbent a monetary sum to relocate its own facilities, the AWS
         relocator must estimate the costs associated with relocating the incumbent by itemizing the anticipated
         cost for items listed in § 27.1164(b). If the sum paid to the incumbent cannot be accounted for, the
         remaining amount is not eligible for reimbursement.

          (1) Third party appraisal. The voluntarily relocating microwave incumbent, must also submit an
              independent third party appraisal of its compensable relocation costs. The appraisal should be
              based on the actual cost of replacing the incumbent's system with comparable facilities and should
              exclude the cost of any equipment upgrades or items outside the scope of § 27.1164(b).

          (2) Identification of links. The AWS relocator or the voluntarily relocating microwave incumbent must
              identify the particular link associated with appropriate expenses (i.e., costs may not be averaged
              over numerous links). Where the AWS relocator or voluntarily relocating microwave incumbent
              relocates both paths of a paired channel microwave link (e.g., 2110–2130 MHz with 2160–2180
              MHz and 2130–2150 MHz with 2180–2200 MHz), the AWS relocator or voluntarily relocating
              microwave incumbent must identify the expenses associated with each paired microwave link.

Miscellaneous Wireless Communications Services

     (c) Full Reimbursement. An AWS relocator who relocates a microwave link that is either fully outside its
         market area or its licensed frequency band may seek full reimbursement through the clearinghouse of
         compensable costs, up to the reimbursement cap as defined in § 27.1164(b). Such reimbursement will
         not be subject to depreciation under the cost-sharing formula.

     (d) Good Faith Requirement. New entrants and incumbent licensees are expected to act in good faith in
         satisfying the cost-sharing obligations under §§ 27.1160 through 27.1174. The requirement to act in good
         faith extends to, but is not limited to, the preparation and submission of the documentation required in
         paragraph (b) of this section.

     (e) MSS Participation in the Clearinghouse. MSS operators are not required to submit reimbursements to the
         clearinghouse for links relocated due to interference from MSS space-to-Earth downlink operations, but
         may elect to do so, in which case the MSS operator must identify the reimbursement claim as such and
         follow the applicable procedures governing reimbursement in part 27. MSS reimbursement rights and
         cost-sharing obligations for space-to-Earth downlink operations are governed by § 101.82 of this chapter.

     (f) Reimbursement for Self-relocating FMS links in the 2130–2150 MHz and 2180–2200 MHz bands. Where a
         voluntarily relocating microwave incumbent relocates a paired microwave link with paths in the
         2130–2150 MHz and 2180–2200 MHz bands, it may not seek reimbursement from MSS operators, but is
         entitled to reimbursement from the first AWS beneficiary for its actual costs for relocating the paired link,
         subject to the reimbursement cap in § 27.1164(b). This amount is subject to depreciation as specified in
         § 27.1164(b). An AWS licensee who is obligated to reimburse relocation costs under this rule is entitled to
         obtain reimbursement from other AWS beneficiaries in accordance with §§ 27.1164 and 27.1168. For
         purposes of applying the cost-sharing formula relative to other AWS licensees that benefit from the self-
         relocation, depreciation shall run from the date on which the clearinghouse issues the notice of an
         obligation to reimburse the voluntarily relocating microwave incumbent.

§ 27.1168 Triggering a Reimbursement Obligation.
     (a) The clearinghouse will apply the following test to determine when an AWS entity has triggered a cost-
         sharing obligation and therefore must pay an AWS relocator, MSS relocator, or a voluntarily relocating
         microwave incumbent in accordance with the formula detailed in § 27.1164:

           (1) All or part of the relocated microwave link was initially co-channel with the licensed AWS band(s) of
               the AWS entity or the selected assignment of the MSS operator that seeks and obtains ATC authority
               (see § 25.149(a)(2)(i) of this chapter);

           (2) An AWS relocator, MSS relocator or a voluntarily relocating microwave incumbent has paid the
               relocation costs of the microwave incumbent; and

           (3) The AWS or MSS entity is operating or preparing to turn on a fixed base station at commercial power
               and the fixed base station is located within a rectangle (Proximity Threshold) described as follows:

                 (i)   The length of the rectangle shall be x where x is a line extending through both nodes of the
                       microwave link to a distance of 48 kilometers (30 miles) beyond each node. The width of the
                       rectangle shall be y where y is a line perpendicular to x and extending for a distance of 24
                       kilometers (15 miles) on both sides of x. Thus, the rectangle is represented as follows:

Miscellaneous Wireless Communications Services

                 (ii) If the application of the Proximity Threshold Test indicates that a reimbursement obligation
                      exists, the clearinghouse will calculate the reimbursement amount in accordance with the cost-
                      sharing formula and notify the AWS entity of the total amount of its reimbursement obligation.

     (b) Once a reimbursement obligation is triggered, the AWS entity may not avoid paying its cost-sharing
         obligation by deconstructing or modifying its facilities.

[71 FR 29835, May 24, 2006, as amended at 78 FR 8271, Jan. 5, 2013]

§ 27.1170 Payment issues.
Prior to initiating operations for a newly constructed site or modified existing site, an AWS entity is required to file a
notice containing site-specific data with the clearinghouse. The notice regarding the new or modified site must
provide a detailed description of the proposed site's spectral frequency use and geographic location, including but
not limited to the applicant's name and address, the name of the transmitting base station, the geographic
coordinates corresponding to that base station, the frequencies and polarizations to be added, changed or deleted,
and the emission designator. If a prior coordination notice (PCN) under § 101.103(d) of this chapter is prepared,
AWS entities can satisfy the site-data filing requirement by submitting a copy of their PCN to the clearinghouse.
AWS entities that file either a notice or a PCN have a continuing duty to maintain the accuracy of the site-specific
data on file with the clearinghouse. Utilizing the site-specific data, the clearinghouse will determine if any
reimbursement obligation exists and notify the AWS entity in writing of its repayment obligation, if any. When the
AWS entity receives a written copy of such obligation, it must pay directly to the relocator the amount owed within
30 calendar days.

§ 27.1172 Dispute Resolution Under the Cost-Sharing Plan.
     (a) Disputes arising out of the cost-sharing plan, such as disputes over the amount of reimbursement
         required, must be brought, in the first instance, to the clearinghouse for resolution. To the extent that
         disputes cannot be resolved by the clearinghouse, parties are encouraged to use expedited Alternative
         Dispute Resolution (ADR) procedures, such as binding arbitration, mediation, or other ADR techniques.

     (b) Evidentiary requirement. Parties of interest contesting the clearinghouse's determination of specific cost-
         sharing obligations must provide evidentiary support to demonstrate that their calculation is reasonable
         and made in good faith. Specifically, these parties are expected to exercise due diligence to obtain the
         information necessary to prepare an independent estimate of the relocation costs in question and to file
         the independent estimate and supporting documentation with the clearinghouse.

§ 27.1174 Termination of cost-sharing obligations.
The cost-sharing plan will sunset for all AWS and MSS entities on the same date on which the relocation obligation
for the subject AWS band (i.e., 2110–2150 MHz, 2160–2175 MHz, 2175–2180 MHz, 2180–2200 MHz) in which the
relocated FMS link was located terminates. AWS or MSS entrants that trigger a cost-sharing obligation prior to the
sunset date must satisfy their payment obligation in full.

§ 27.1176 Cost-sharing requirements for AWS in the 2150–2160/62 MHz band.
     (a) Frequencies in the 2150–2160/62 MHz band have been reallocated from the Broadband Radio Service
         (BRS) to AWS. All AWS entities who benefit from another AWS entity's clearance of BRS incumbents from
         this spectrum, including BRS incumbents occupying the 2150–2162 MHz band on a primary basis, must
         contribute to such relocation costs. Only AWS entrants that relocate BRS incumbents are entitled to such
         reimbursement.

     (b) AWS entities may satisfy their reimbursement requirement by entering into private cost-sharing
         agreements or agreeing to terms other than those specified in § 27.1180. However, AWS entities are
         required to reimburse other AWS entities that incur relocation costs and are not parties to the alternative
         agreement. In addition, parties to a private cost-sharing agreement may seek reimbursement through the
         clearinghouse (as discussed in § 27.1178) from AWS entities that are not parties to the agreement. The
         cost-sharing plan is in effect during all phases of BRS relocation until the end of the period specified in §
         27.1190. If an AWS licensee enters into a spectrum leasing arrangement and the spectrum lessee triggers
         a cost-sharing obligation, the licensee is the AWS entity responsible for satisfying cost-sharing obligations
         under these rules.

§ 27.1178 Administration of the Cost-Sharing Plan.
The Wireless Telecommunications Bureau, under delegated authority, will select one or more entities to operate as a
neutral, not-for-profit clearinghouse(s). This clearinghouse(s) will administer the cost-sharing plan by, inter alia,
determining the cost-sharing obligations of AWS entities for the relocation of BRS incumbents from the 2150–2162
MHz band. The clearinghouse filing requirements (see §§ 27.1182(a), 27.1186) will not take effect until an
administrator is selected.

§ 27.1180 The cost-sharing formula.
     (a) An AWS licensee that relocates a BRS system with which it interferes is entitled to pro rata reimbursement
         based on the cost-sharing formula specified in § 27.1164, except that the depreciation factor shall be
         [180−Tm]/180, and the variable C shall be applied as set forth in paragraph (b) of this section.

     (b) C is the actual cost of relocating the system, and includes, but is not limited to, such items as: Radio
         terminal equipment (TX and/or RX—antenna, necessary feed lines, MUX/Modems); towers and/or
         modifications; back-up power equipment; monitoring or control equipment; engineering costs (design/
         path survey); installation; systems testing; FCC filing costs; site acquisition and civil works; zoning costs;
         training; disposal of old equipment; test equipment (vendor required); spare equipment; project
         management; site lease renegotiation; required antenna upgrades for interference control; power plant
         upgrade (if required); electrical grounding systems; Heating Ventilation and Air Conditioning (HVAC) (if
         required); alternate transport equipment; leased facilities; and end user units served by the base station
         that is being relocated. In addition to actual costs, C may include the cost of an independent third party
         appraisal conducted pursuant to § 27.1182(a)(3) and incumbent transaction expenses that are directly
         attributable to the relocation, subject to a cap of two percent of the “hard” costs involved. Hard costs are
         defined as the actual costs associated with providing a replacement system, such as equipment and
         engineering expenses. There is no cap on the actual costs of relocation.

     (c) An AWS system shall be considered an interfering system for purposes of this rule if the AWS system is in
         all or part of the BRS frequency band and operates within line of sight to BRS operations under the
         applicable test specified in § 27.1184. An AWS relocator that relocates a BRS system with which it does
         not interfere is entitled to full reimbursement, as specified in § 27.1182(c).

§ 27.1182 Reimbursement under the Cost-Sharing Plan.
     (a) Registration of reimbursement rights.

           (1) To obtain reimbursement, an AWS relocator must submit documentation of the relocation agreement
               to the clearinghouse within 30 calendar days of the date a relocation agreement is signed with an
               incumbent. In the case of involuntary relocation, an AWS relocator must submit documentation of
               the relocated system within 30 calendar days after the end of the one-year trial period.

           (2) Registration of any BRS system shall include:

                 (i)   A description of the system's frequency use;

                 (ii) If the system exclusively provides one-way transmissions to subscribers, the Geographic
                      Service Area of the system; and

                (iii) If the system does not exclusively provide one-way transmission to subscribers, the system hub
                      antenna's geographic location and the above ground level height of the system's receiving
                      antenna centerline.

          (3) The AWS relocator must also include with its system registration an independent third party
              appraisal of the compensable relocation costs. The appraisal should be based on the actual cost of
              replacing the incumbent's system with comparable facilities and should exclude the cost of any
              equipment upgrades that are not necessary to the provision of comparable facilities. An AWS
              relocator may submit registration without a third party appraisal if it consents to binding resolution
              by the clearinghouse of any good faith cost disputes regarding the reimbursement claim, under the
              following standard: The relocator shall bear the burden of proof, and be required to demonstrate by
              clear and convincing evidence that its request does not exceed the actual cost of relocating the
              relevant BRS system or systems to comparable facilities. Failure to satisfy this burden of proof will
              result in loss of rights to subsequent reimbursement of the disputed costs from any AWS licensee.

     (b) Documentation of expenses. Once relocation occurs, the AWS relocator must submit documentation
         itemizing the amount spent for items specifically listed in § 27.1180(b), as well as any reimbursable items
         not specifically listed in § 27.1180(b) that are directly attributable to actual relocation costs. Specifically,
         the AWS relocator must submit, in the first instance, only the uniform cost data requested by the
         clearinghouse along with copies, without redaction, of the relocation agreement, if any, and the third party
         appraisal described in (a)(3), of this section, if prepared. The AWS relocator must identify the particular
         system associated with appropriate expenses (i.e., costs may not be averaged over numerous systems).
         If an AWS relocator pays a BRS incumbent a monetary sum to relocate its own facilities in whole or in
         part, the AWS relocator must itemize the actual costs to the extent determinable, and otherwise must
         estimate the actual costs associated with relocating the incumbent and itemize these costs. If the sum
         paid to the incumbent cannot be accounted for, the remaining amount is not eligible for reimbursement.
         All AWS relocators seeking reimbursement through the clearinghouse have an ongoing duty to maintain
         all relevant records of BRS relocation-related expenses until the sunset of cost-sharing obligations, and to
         provide, upon request, such documentation, including a copy of the independent appraisal if one was
         conducted, to the clearinghouse, the Commission, or AWS entrants that trigger a cost-sharing obligation.

     (c) Full reimbursement. An AWS relocator who relocates a BRS system that is either:

          (1) Wholly outside its frequency band; or

          (2) Not within line of sight of the relocator's transmitting base station may seek full reimbursement
              through the clearinghouse of compensable costs. Such reimbursement will not be subject to
              depreciation under the cost-sharing formula.

     (d) Good Faith Requirement. New entrants and incumbent licensees are expected to act in good faith in
         satisfying the cost-sharing obligations under §§ 27.1176 through 27.1190. The requirement to act in good
         faith extends to, but is not limited to, the preparation and submission of the documentation required in
         paragraph (b) of this section.

§ 27.1184 Triggering a reimbursement obligation.
     (a) The clearinghouse will apply the following test to determine when an AWS entity has triggered a cost-
         sharing obligation and therefore must pay an AWS relocator of a BRS system in accordance with the
         formula detailed in § 27.1180:

          (1) All or part of the relocated BRS system was initially co-channel with the licensed AWS band(s) of the
              AWS entity;

          (2) An AWS relocator has paid the relocation costs of the BRS incumbent; and

          (3) The other AWS entity has turned on or is preparing to turn on a fixed base station at commercial
              power and the incumbent BRS system would have been within the line of sight of the AWS entity's
              fixed base station, defined as follows.

                (i)   For a BRS system using the 2150–2160/62 MHz band exclusively to provide one-way
                      transmissions to subscribers, the clearinghouse will determine whether there is an
                      unobstructed signal path (line of sight) to the incumbent licensee's geographic service area
                      (GSA), based on the following criteria: use of 9.1 meters (30 feet) for the receiving antenna
                      height, use of the actual transmitting antenna height and terrain elevation, and assumption of
                      4/3 Earth radius propagation conditions. Terrain elevation data must be obtained from the U.S.
                      Geological Survey (USGS) 3-second database. All coordinates used in carrying out the required
                      analysis shall be based upon use of NAD–83.

                (ii) For all other BRS systems using the 2150–2160/62 MHz band, the clearinghouse will determine
                     whether there is an unobstructed signal path (line of sight) to the incumbent licensee's receive
                     station hub using the method prescribed in “Methods for Predicting Interference from
                     Response Station Transmitters and to Response Station Hubs and for Supplying Data on
                     Response Station Systems. MM Docket 97–217,” in Amendment of 47 CFR parts 1, 21 and 74

                     Appendix D.

     (b) If the application of the trigger test described in paragraphs (a)(3)(i) and (ii) of this section, indicates that
         a reimbursement obligation exists, the clearinghouse will calculate the reimbursement amount in
         accordance with the cost-sharing formula and notify the subsequent AWS entity of the total amount of its
         reimbursement obligation.

     (c) Once a reimbursement obligation is triggered, the AWS entity may not avoid paying its cost-sharing
         obligation by deconstructing or modifying its facilities.

§ 27.1186 Payment issues.
Payment of cost-sharing obligations for the relocation of BRS systems in the 2150–60/62 MHz band is subject to
the rules set forth in § 27.1170. If an AWS licensee is initiating operations for a newly constructed site or modified
existing site in licensed bands overlapping the 2150–2160/62 MHz band, the AWS licensee must file with the
clearinghouse, in addition to the site-specific data required by § 27.1170, the above ground level height of the
transmitting antenna centerline. AWS entities have a continuing duty to maintain the accuracy of the site-specific
data on file with the clearinghouse.

§ 27.1188 Dispute resolution under the Cost-Sharing Plan.
     (a) Disputes arising out of the cost-sharing plan, such as disputes over the amount of reimbursement
         required, must be brought, in the first instance, to the clearinghouse for resolution. To the extent that
         disputes cannot be resolved by the clearinghouse, parties are encouraged to use expedited Alternative
         Dispute Resolution (ADR) procedures, such as binding arbitration, mediation, or other ADR techniques.

Miscellaneous Wireless Communications Services

     (b) Evidentiary requirement. Parties of interest contesting the clearinghouse's determination of specific cost-
         sharing obligations must provide evidentiary support to demonstrate that their calculation is reasonable
         and made in good faith. Specifically, these parties are expected to exercise due diligence to obtain the
         information necessary to prepare an independent estimate of the relocation costs in question and to file
         the independent estimate and supporting documentation with the clearinghouse.

§ 27.1190 Termination of cost-sharing obligations.
The plan for cost-sharing in connection with BRS relocation will sunset for all AWS entities fifteen years after the
relocation sunset period for BRS relocation commences, i.e., fifteen years after the first AWS licenses are issued in
any part of the 2150–2162 MHz band. AWS entrants that trigger a cost-sharing obligation prior to the sunset date
must satisfy their payment obligation in full.

§ 27.1200 Change to BRS and EBS.
     (a) As of January 10, 2005, licensees assigned to the Multipoint Distribution Service (MDS) and the
         Multichannel Multipoint Distribution Service (MMDS) shall be reassigned to the Broadband Radio Service
         (BRS) and licensees in the Instructional Television Fixed Service (ITFS) shall be reassigned to the
         Educational Broadband Service (EBS).

§ 27.1201 [Reserved]
§ 27.1202 Cable/BRS cross-ownership.
     (a) Initial or modified authorizations for BRS stations may not be granted to a cable operator if a portion of
         the BRS station's protected services area is within the portion of the franchise area actually served by the
         cable operator's cable system and the cable operator will be using the BRS station as a multichannel
         video programming distributor (as defined in § 76.64(d) of this chapter). No cable operator may acquire
         such authorization either directly, or indirectly through an affiliate owned, operated, or controlled by or
         under common control with a cable operator if the cable operator will use the BRS station as a
         multichannel video programming distributor.

     (b) No licensee of a station in this service may lease transmission time or capacity to a cable operator either
         directly, or indirectly through an affiliate owned, operated, controlled by, or under common control with a
         cable operator, if a portion of the BRS station's protected services area is within the portion of the
         franchise area actually served by the cable operator's cable system the cable operator will use the BRS
         station as a multichannel video programming distributor.

     (c) Applications for new stations, station modifications, assignments or transfers of control by cable
         operators of BRS stations shall include a showing that no portion of the GSA of the BRS station is within
         the portion of the franchise area actually served by the cable operator's cable system, or of any entity
         indirectly affiliated, owned, operated, controlled by, or under common control with the cable operator.
         Alternatively, the cable operator may certify that it will not use the BRS station to distribute multichannel
         video programming.

     (d) In applying the provisions of this section, ownership and other interests in BRS licensees or cable
         television systems will be attributed to their holders and deemed cognizable pursuant to the following
         criteria:

          (1) Except as otherwise provided herein, partnership and direct ownership interests and any voting stock
              interest amounting to 5% or more of the outstanding voting stock of a corporate BRS licensee or
              cable television system will be cognizable;

          (2) Investment companies, as defined in 15 U.S.C. 80a–3, insurance companies and banks holding stock
              through their trust departments in trust accounts will be considered to have a cognizable interest
              only if they hold 20% or more of the outstanding voting stock of a corporate BRS licensee or cable
              television system, or if any of the officers or directors of the BRS licensee or cable television system
              are representatives of the investment company, insurance company or bank concerned. Holdings by
              a bank or insurance company will be aggregated if the bank or insurance company has any right to
              determine how the stock will be voted. Holdings by investment companies will be aggregated if
              under common management.

          (3) Attribution of ownership interests in a BRS licensee or cable television system that are held indirectly
              by any party through one or more intervening corporations will be determined by successive
              multiplication of the ownership percentages for each link in the vertical ownership chain and
              application of the relevant attribution benchmark to the resulting product, except that wherever the
              ownership percentage for any link in the chain exceeds 50%, it shall not be included for purposes of
              this multiplication. For purposes of paragraph (d)(9) of this section, attribution of ownership
              interests in a BRS licensee or cable television system that are held indirectly by any party through
              one or more intervening organizations will be determined by successive multiplication of the
              ownership percentages for each link in the vertical ownership chain and application of the relevant
              attribution benchmark to the resulting product, and the ownership percentage for any link in the
              chain that exceeds 50% shall be included for purposes of this multiplication. For example, except for
              purposes of paragraph (d)(9) of this section, if A owns 10% of company X, which owns 60% of
              company Y, which owns 25% of “Licensee,” then X's interest in “Licensee” would be 25% (the same as
              Y's interest because X's interest in Y exceeds 50%), and A's interest in “Licensee” would be 2.5% (0.1
              × 0.25). Under the 5% attribution benchmark, X's interest in “Licensee” would be cognizable, while A's
              interest would not be cognizable. For purposes of paragraph (d)(9) of this section, X's interest in
              “Licensee” would be 15% (0.6 × 0.25) and A's interest in “Licensee” would be 1.5% (0.1 × 0.6 × 0.25).
              Neither interest would be attributed under paragraph (d)(9) of this section.

          (4) Voting stock interests held in trust shall be attributed to any person who holds or shares the power to
              vote such stock, to any person who has the sole power to sell such stock, and to any person who has
              the right to revoke the trust at will or to replace the trustee at will. If the trustee has a familial,
              personal or extra-trust business relationship to the grantor or the beneficiary, the grantor or
              beneficiary, as appropriate, will be attributed with the stock interests held in trust. An otherwise
              qualified trust will be ineffective to insulate the grantor or beneficiary from attribution with the trust's
              assets unless all voting stock interests held by the grantor or beneficiary in the relevant BRS licensee
              or cable television system are subject to said trust.

          (5) Subject to paragraph (d)(9) of this section, holders of non-voting stock shall not be attributed an
              interest in the issuing entity. Subject to paragraph (d)(9) of this section, holders of debt and
              instruments such as warrants, convertible debentures, options or other non-voting interests with
              rights of conversion to voting interests shall not be attributed unless and until conversion is effected.

                       television activities of the partnership and the licensee or system so certifies. An interest in a
                       Limited Liability Company (“LLC”) or Registered Limited Liability Partnership (“RLLP”) shall be
                       attributed to the interest holder unless that interest holder is not materially involved, directly or
                       indirectly, in the management or operation of the BRS or cable television activities of the
                       partnership and the licensee or system so certifies.

                (ii) For a licensee or system that is a limited partnership to make the certification set forth in
                     paragraph (d)(6)(i) of this section, it must verify that the partnership agreement or certificate of
                     limited partnership, with respect to the particular limited partner exempt from attribution,
                     establishes that the exempt limited partner has no material involvement, directly or indirectly, in
                     the management or operation of the BRS or cable television activities of the partnership. For a
                     licensee or system that is an LLC or RLLP to make the certification set forth in paragraph
                     (d)(6)(i) of this section, it must verify that the organizational document, with respect to the
                     particular interest holder exempt from attribution, establishes that the exempt interest holder
                     has no material involvement, directly or indirectly, in the management or operation of the BRS or
                     cable television activities of the LLC or RLLP. Irrespective of the terms of the certificate of
                     limited partnership or partnership agreement, or other organizational document in the case of
                     an LLC or RLLP, however, no such certification shall be made if the individual or entity making
                     the certification has actual knowledge of any material involvement of the limited partners, or
                     other interest holders in the case of an LLC or RLLP, in the management or operation of the BRS
                     or cable television businesses of the partnership or LLC or RLLP.

                (iii) In the case of an LLC or RLLP, the licensee or system seeking installation shall certify, in
                      addition, that the relevant state statute authorizing LLCs permits an LLC member to insulate
                      itself as required by our criteria.

           (7) Officers and directors of a BRS licensee or cable television system are considered to have a
               cognizable interest in the entity with which they are so associated. If any such entity engages in
               businesses in addition to its primary business of BRS or cable television service, it may request the
               Commission to waive attribution for any officer or director whose duties and responsibilities are
               wholly unrelated to its primary business. The officers and directors of a parent company of a BRS
               licensee or cable television system, with an attributable interest in any such subsidiary entity, shall
               be deemed to have a cognizable interest in the subsidiary unless the duties and responsibilities of
               the officer or director involved are wholly unrelated to the BRS licensee or cable television system
               subsidiary, and a statement properly documenting this fact is submitted to the Commission. The
               officers and directors of a sister corporation of a BRS licensee or cable television system shall not be
               attributed with ownership of these entities by virtue of such status.

           (8) Discrete ownership interests will be aggregated in determining whether or not an interest is
               cognizable under this section. An individual or entity will be deemed to have a cognizable investment
               if:

                 (i)   The sum of the interests held by or through “passive investors” is equal to or exceeds 20
                       percent; or

                (ii) The sum of the interests other than those held by or through “passive investors” is equal to or
                     exceeds 5 percent; or

          (9) Notwithstanding paragraphs (d)(5) and (d)(6) of this section, the holder of an equity or debt interest
              or interests in a BRS licensee or cable television system subject to the BRS/cable cross-ownership
              rule (“interest holder”) shall have that interest attributed if:

                (i)   The equity (including all stockholdings, whether voting or nonvoting, common or preferred) and
                      debt interest or interests, in the aggregate, exceed 33 percent of the total asset value (all equity
                      plus all debt) of that BRS licensee or cable television system; and

                (ii) The interest holder also holds an interest in a BRS licensee or cable television system that is
                     attributable under this section (other than this paragraph) and which operates in any portion of
                     the franchise area served by that cable operator's cable system.

          (10) The term “area served by a cable system” means any area actually passed by the cable operator's
               cable system and which can be connected for a standard connection fee.

          (11) As used in this section “cable operator” shall have the same definition as in § 76.5 of this chapter.

     (e) The Commission will entertain requests to waive the restrictions in paragraph (a) of this section where
         necessary to ensure that all significant portions of the franchise area are able to obtain multichannel
         video service.

     (f) The provisions of paragraphs (a) through (e) of this section will not apply to one BRS channel used to
         provide locally-produced programming to cable headends. Locally-produced programming is
         programming produced in or near the cable operator's franchise area and not broadcast on a television
         station available within that franchise area. A cable operator will be permitted one BRS channel for this
         purpose, and no more than one BRS channel may be used by a cable television company or its affiliate or
         lessor pursuant to this paragraph. The licensee for a cable operator providing local programming pursuant
         to a lease must include in a notice filed with the Wireless Telecommunications Bureau a cover letter
         explicitly identifying itself or its lessees as a local cable operator and stating that the lease was executed
         to facilitate the provision of local programming. The first application or the first lease notification in an
         area filed with the Commission will be entitled to the exemption. The limitations on one BRS channel per
         party and per area include any cable/BRS operations or cable/EBS operations. The cable operator must
         demonstrate in its BRS application that the proposed local programming will be provided within one year
         from the date its application is granted. Local programming service pursuant to a lease must be provided
         within one year of the date of the lease or one year of grant of the licensee's application for the leased
         channel, whichever is later. If a BRS license for these purposes is granted and the programming is
         subsequently discontinued, the license will be automatically forfeited the day after local programming
         service is discontinued.

     (g) Applications filed by cable television companies, or affiliates, for BRS channels prior to February 8, 1990,
         will not be subject to the prohibitions of this section. Applications filed on February 8, 1990, or thereafter
         will be returned. Lease arrangements between cable and BRS entities for which a lease or a firm
         agreement was signed prior to February 8, 1990, will also not be subject to the prohibitions of this section.
         Leases between cable television companies, or affiliates, and BRS station licensees, conditional licensees,
         or applicants executed on February 8, 1990, or thereafter, are invalid.

          (1) Applications filed by cable operators, or affiliates, for BRS channels prior to February 8, 1990, will not
              be subject to the prohibitions of this section. Except as provided in paragraph (g)(2)of this section,

                this section, leases between cable operators, or affiliates, and BRS/EBS station licensees, conditional
                licensees, or applicants executed on or before February 8, 1990, or thereafter are invalid.

          (2) Applications filed by cable operators, or affiliates for BRS channels after February 8, 1990, and prior
              to October 5, 1992, will not be subject to the prohibition of this section, if, pursuant to the then
              existing overbuild or rural exceptions, the applications were allowed under the then existing cable/
              BRS cross-ownership prohibitions. Lease arrangements between cable operators and BRS entities
              for which a lease or firm agreement was signed after February 8, 1990, and prior to October 5, 1992,
              will not be subject to the prohibitions of this section, if, pursuant to the then existing rural and
              overbuild exceptions, the lease arrangements were allowed.

          (3) The limitations on cable television ownership in this section do not apply to any cable operator in any
              franchise area in which a cable operator is subject to effective competition as determined under
              section 623(l) of the Communications Act.

§ 27.1204 EBS Tribal priority filing window.
     (a) The Commission will specify by public notice a window filing period for applications for new EBS stations
         on rural Tribal Lands. EBS applications for new facilities will be accepted only during this window.
         Applications submitted prior to the window opening date identified in the public notice will be returned as
         premature. Applications submitted after the deadline will be dismissed with prejudice as untimely.

     (b) Applicants in the Tribal priority filing window must demonstrate that they are eligible to file in that window.
         To be considered eligible for the Tribal priority window, an applicant must be:

          (1) A federally recognized American Indian Tribe or Alaska Native Village; or an entity that is owned and
              controlled by a federally-recognized Tribe or a consortium of federally-recognized Tribes;

          (2) Requesting a license on Tribal Land, which is defined to be any federally recognized Indian Tribe's
              reservation, pueblo or colony, including former reservations in Oklahoma, Alaska Native regions
              established pursuant to the Alaska Native Claims Settlement Act (85 Stat. 688) and Indian
              Allotments, see § 54.400(e) of this chapter, as well as Hawaiian Home Lands—areas held in trust for
              native Hawaiians by the State of Hawaii, pursuant to the Hawaiian Homes Commission Act, 1920,
              July 9, 1921, 42 Stat 108, et seq., as amended; and any lands designated prior to July 10, 2019, as
              Tribal Lands pursuant to the designation process contained in § 54.412 of this chapter;

          (3) Requesting a GSA in a rural area, which is defined to be lands that are not part of an urbanized area
              or urban cluster area with a population equal to or greater than 50,000; and

          (4) Have a local presence on the Tribal Land for which they are applying.

     (c) Following the close of the Tribal priority window, the Commission will issue a public notice of acceptance
         for filing of applications submitted pursuant to paragraph (b) of this section that meet technical and legal
         requirements and that are not in conflict with any other application filed during the window. Petitions to
         deny such applications may be filed within 30 days of such public notice. A copy of any petition to deny
         must be served on the applicant.

§ 27.1206 Geographic service area.
     (a) BRS:

           (1) For BRS incumbent licenses granted before September 15, 1995, the geographic service area (GSA)
               is the area that is bounded by a circle having a 35 mile radius and centered at the station's reference
               coordinates, which was the previous PSA entitled to incumbent licensees prior to January 10, 2005,
               and is bounded by the chord(s) drawn between intersection points of the licensee's previous 35 mile
               PSA and those of respective adjacent market, co-channel licensees;

           (2) For BRS BTA authorization holders, the GSA for a channel is the BTA, subject to the exclusion of
               overlapping, co-channel incumbent GSAs created on January 10, 2005.

           (3) If an incumbent BRS license is cancelled or is forfeited, the GSA area of the incumbent station shall
               dissolve and the right to operate in that area automatically reverts to the GSA licensee that held the
               corresponding BTA.

     (b) EBS:

           (1) Existing EBS licensees.

                 (i)   The GSA of EBS licenses on the E and F channel groups is defined in § 27.1216. EBS licensees
                       on the E and F channel groups are prohibited from expanding their GSAs.

                 (ii) For incumbent EBS licenses not in the E and F channel groups in effect as of October 25, 2019,
                      the geographic service area (GSA) is the area that is bounded by a circle having a 35 mile radius
                      and centered at the station's reference coordinates, which was the previous PSA entitled to
                      incumbent licensees prior to January 10, 2005, and is bounded by the chord(s) drawn between
                      intersection points of the licensee's previous 35 mile PSA and those of respective adjacent
                      market, co-channel licensees.

§ 27.1207 Service areas and authorizations.
     (a) Initial authorizations for BRS granted after January 1, 2008, shall be blanket licenses for all BRS
         frequencies identified in § 27.5(i)(2). Except for incumbent BRS licenses, BRS service areas are the 1992
         version of Basic Trading Areas (BTAs) defined by Rand McNally, or additional service areas similar to
         BTAs adopted by the Commission. The market area for each license will be listed on the license
         authorization. The following are additional BRS service areas in places where Rand McNally has not
         defined BTAs: American Samoa; Guam; Gulf of Mexico Zone A; Gulf of Mexico Zone B; Gulf of Mexico
         Zone C; Northern Mariana Islands; Mayaguez/Aguadilla-Ponce, Puerto Rico; San Juan, Puerto Rico; and
         the United States Virgin Islands. The boundaries of Gulf of Mexico Zone A are from an area twelve
         nautical miles from the shoreline at mean high tide on the north and east, to the limit of the Outer
         Continental Shelf to the south, and to longitude 91°00′ to the west. The boundaries of Gulf of Mexico Zone
         B are from an area twelve nautical miles from the shoreline at mean high tide on the north, to the limit of
         the Outer Continental Shelf to the south, to longitude 91°00′ to the east, and to longitude 94°00′ to the
         west. The boundaries of Gulf of Mexico Zone C are from an area twelve nautical miles from the shoreline
         at mean high tide on the north and west, to longitude 94°00′ to the east, and to a line 281 kilometers from
         the reference point at Linares, N.L., Mexico on the southwest. The Mayaguez/Aguadilla-Ponce, PR, service
         area consists of the following municipios: Adjuntas, Aguada, Aguadilla, Anasco, Arroyo, Cabo Rojo,
         Coamo, Guanica, Guayama, Guayanilla, Hormigueros, Isabela, Jayuya, Juana Diaz, Lajas, Las Marias,

         Salinas, San German, Santa Isabel, Villalba and Yauco. The San Juan service area consists of all other
         municipios in Puerto Rico.

     (b) For EBS initial licenses issued after October 25, 2019, except for licenses issued in the Tribal Priority
         Window, the GSA is the county for which the license is issued, subject to the exclusion of overlapping, co-
         channel incumbent GSAs. For purposes of this subpart, counties are defined using the United States
         Census Bureau's data reflecting county legal boundaries and names valid through January 1, 2017. Except
         for licenses issued in the Tribal Priority Window, there shall be three initial authorizations issued in each
         county: One authorization for channels A1, A2, A3, B1, B2, B3, C1, C2, and C3; the second authorization for
         channels D1, D2, D3, JA1, JA2, JA3, JB1, JB2, JB3, JC1, JC2, JC3, JD1, JD2, JD3, A4, B4, C4, D4, and G4;

         incentives in the auction process. See 47 CFR 1.2110.

     (c) Installment payments. Small businesses and small business consortia may elect to pay the full amount of
         their winning bids in Commission auctions commencing prior to January 1, 2004 for BTA service areas in
         installments over a ten (10) year period running from the date that their BTA authorizations are issued.

          (1) Upon issuance of a BTA authorization to a winning bidder in a Commission auction commencing
              prior to January 1, 2004 that is eligible for installment payments, the Commission will notify such
              eligible BTA authorization holder of the terms of its installment payment plan. For BRS, such
              installment payment plans will:

                (i)   Impose interest based on the rate of ten (10) year U.S. Treasury obligations at the time of
                      issuance of the BTA authorization, plus two and one half (2.5) percent;

                (ii) Allow installment payments for a ten (10) year period running from the date that the BTA
                     authorization is issued;

                (iii) Begin with interest-only payments for the first two (2) years; and

                (iv) Amortize principal and interest over the remaining years of the ten (10) year period running
                     from the date that the BTA authorization is issued.

          (2) Conditions and obligations. See § 1.2110(g)(4) of this chapter.

          (3) Unjust enrichment. If an eligible BTA authorization holder that utilizes installment financing under
              this subsection seeks to partition, pursuant to applicable rules, a portion of its BTA containing one-
              third or more of the population of the area within its control in the licensed BTA to an entity not
              meeting the eligibility standards for installment payments, the holder must make full payment of the
              remaining unpaid principal and any unpaid interest accrued through the date of partition as a
              condition of approval.

     (d) Reduced upfront payments. For purposes of Commission auctions commencing prior to January 1, 2004
         for BRS licenses, a prospective bidder that qualifies as a small business, or as a small business consortia,
         is eligible for a twenty-five (25) percent reduction in the amount of the upfront payment otherwise
         required. To be eligible to bid on a particular BTA, a small business will be required to submit an upfront
         payment equal to seventy-five (75) percent of the upfront payment amount specified for that BTA in the
         public notice listing the upfront payment amounts corresponding to each BTA service area being
         auctioned.

     (e) Bidding credits. For purposes of Commission auctions commencing prior to January 1, 2004 for BRS
         licenses, a winning bidder that qualifies as a small business, or as a small business consortia, may use a
         bidding credit of fifteen (15) percent to lower the cost of its winning bid on any of the BTA authorizations
         awarded in the Commission BRS auctions commencing prior to January 1, 2004.

     (f) Short-form application certification; Long-form application or statement of intention disclosure. A BRS
         applicant in a Commission auction commencing prior to January 1, 2004 claiming designated entity
         status shall certify on its short-form application that it is eligible for the incentives claimed. A designated
         entity that is a winning bidder for a BTA service area(s) shall, in addition to information otherwise required,
         file an exhibit to either its initial long-form application for a BRS station license, or to its statement of
         intention with regard to the BTA, which discloses the gross revenues for each of the past three years of
         the winning bidder and its affiliates. This exhibit shall describe how the winning bidder claiming status as

                                                  TECHNICAL STANDARDS

§ 27.1220 Transmission standards.
The width of a channel in the LBS and UBS is 5.5 MHz, with the exception of BRS channels 1 and 2 which are 6.0
MHz. The width of all channels in the MBS is 6 MHz. However, the licensee may subchannelize its authorized
bandwidth, provided that digital modulation is employed and the aggregate power does not exceed the authorized
power for the channel. The licensee may also, jointly with other licensees, transmit utilizing bandwidth in excess of
its authorized bandwidth, provided that digital modulation is employed, all power spectral density requirements set
forth in this part are met and the out-of-band emissions restrictions set forth in § 27.53 are met at the edges of the
channels employed.

§ 27.1221 Interference protection.
     (a) Interference protection will be afforded to BRS and EBS on a station-by-station basis based on the heights
         of the stations in the LBS and UBS and also on height benchmarking, although the heights of antennas
         utilized are not restricted.

     (b) Height benchmarking. Height benchmarking is defined for pairs of base stations, one in each of two
         proximate geographic service areas (GSAs). The height benchmark, which is defined in meters (hbm) for a
         particular base station relative to a base station in another GSA, is equal to the distance, in kilometers,
         from the base station along a radial to the nearest point on the GSA boundary of the other base station
         squared (Dkm2) and then divided by 17. That is, hb (m) = Dkm2/17. A base station antenna will be
         considered to be within its applicable height benchmark relative to another base station if the height in
         meters of its centerline of radiation above average elevation (HAAE) calculated along the straight line
         between the two base stations in accordance with § 24.53(b) and (c) of this chapter does not exceed the
         height benchmark (hbm). A base station antenna will be considered to exceed its applicable height
         benchmark relative to another base station if the HAAE of its centerline of radiation calculated along the
         straight line between the two base stations in accordance with § 24.53(b) and (c) of this chapter exceeds
         the height benchmark (hbm).

     (c) Protection for receiving antennas not exceeding the height benchmark. Absent agreement between the
         two licensees to the contrary, if a transmitting antenna of one BRS/EBS licensee's base station exceeds
         its applicable height benchmark and such licensee is notified by another BRS/EBS licensee that it is

          generating an undesired signal level in excess of −107 dBm/5.5 megahertz at the receiver of a co-channel
          base station that is within its applicable height benchmark, then the licensee of the base station that
          exceeds its applicable height benchmark shall either limit the undesired signal at the receiver of the
          protected base station to −107dBm/5.5 megahertz or less or reduce the height of its transmission
          antenna to no more than the height benchmark. If the interfering base station has been modified to
          increase the EIRP transmitted in the direction of the protected base station, it shall be deemed to have
          commenced operations on the date of such modification. Such corrective action shall be completed no
          later than:

           (i)   24 hours after receiving such notification, if the base station that exceeds its height benchmark
                 commenced operations after the station that is within its applicable height benchmark; or

           (ii) 90 days after receiving such notification, if the base station that exceeds its height commenced
                operations prior to the station that is within its applicable height benchmark. For purposes of this
                section, if the interfering base station has been modified to increase the EIRP transmitted in the
                direction of the victim base station, it shall be deemed to have commenced operations on the date of
                such modification.

     (d) No Protection from a transmitting antenna not exceeding the height benchmark. The licensee of a base
         station transmitting antenna less than or equal to its applicable height benchmark shall not be required
         pursuant to paragraph (c) of this section to limit that antennas undesired signal level to −107dBm/5.5
         megahertz or less at the receiver of any co-channel base station.

     (e) No protection for a receiving-antenna exceeding the height benchmark. The licensee of a base station
         receive antenna that exceeds its applicable height benchmark shall not be entitled pursuant to paragraph
         (c) of this section to insist that any co-channel base station limit its undesired signal level to −107dBm/
         5.5 megahertz or less at the receiver.

     (f) Information exchange. A BRS/EBS licensee shall provide the geographic coordinates, the height above
         ground level of the center of radiation for each transmit and receive antenna, and the date transmissions
         commenced for each of the base stations in its GSA within 30 days of receipt of a request from a co-
         channel BRS/EBS licensee with an operational base station located in a proximate GSA. Information
         shared pursuant to this section shall not be disclosed to other parties except as required to ensure
         compliance with this section.

Miscellaneous Wireless Communications Services

§ 27.1250 Transition of the 2150–2160/62 MHz band from the Broadband Radio Service to the
Advanced Wireless Service.
The 2150–2160/62 MHz band has been allocated for use by the Advanced Wireless Service (AWS). The rules in this
section provide for a transition period during which AWS licensees may relocate existing Broadband Radio Service
(BRS) licensees using these frequencies to their assigned frequencies in the 2496–2690 MHz band or other media.

     (a) AWS licensees and BRS licensees shall engage in mandatory negotiations for the purpose of agreeing to
         terms under which the BRS licensees would:

          (1) Relocate their operations to other frequency bands or other media; or alternatively

          (2) Accept a sharing arrangement with the AWS licensee that may result in an otherwise impermissible
              level of interference to the BRS operations.

     (b) If no agreement is reached during the mandatory negotiation period, an AWS licensee may initiate
         involuntary relocation procedures. Under involuntary relocation, the incumbent is required to relocate,
         provided that the AWS licensee meets the conditions of § 27.1252.

     (c) Relocation of BRS licensees by AWS licensees will be subject to a three-year mandatory negotiation
         period. BRS licensees may suspend the running of the three-year negotiation period for up to one year if
         the BRS licensee cannot be relocated to comparable facilities at the time the AWS licensee seeks entry
         into the band.

§ 27.1251 Mandatory negotiations.
     (a) Once mandatory negotiations have begun, a BRS licensee may not refuse to negotiate and all parties are
         required to negotiate in good faith. Good faith requires each party to provide information to the other that
         is reasonably necessary to facilitate the relocation process. The BRS licensee is required to cooperate
         with an AWS licensee's request to provide access to the facilities to be relocated, other than the BRS
         customer location, so that an independent third party can examine the BRS system and prepare an
         appraisal of the costs to relocate the incumbent. In evaluating claims that a party has not negotiated in
         good faith, the FCC will consider, inter alia, the following factors:

          (1) Whether the AWS licensee has made a bona fide offer to relocate the BRS licensee to comparable
              facilities in accordance with § 27.1252(b);

          (2) If the BRS licensee has demanded a premium, the type of premium requested (e.g., whether the
              premium is directly related to relocation, such as analog-to-digital conversions, versus other types of
              premiums), and whether the value of the premium as compared to the cost of providing comparable
              facilities is disproportionate (i.e., whether there is a lack of proportion or relation between the two);

          (3) What steps the parties have taken to determine the actual cost of relocation to comparable facilities;

          (4) Whether either party has withheld information requested by the other party that is necessary to
              estimate relocation costs or to facilitate the relocation process.

     (b) Any party alleging a violation of our good faith requirement must attach an independent estimate of the
         relocation costs in question to any documentation filed with the Commission in support of its claim. An
         independent cost estimate must include a specification for the comparable facility and a statement of the
         costs associated with providing that facility to the incumbent licensee.

Miscellaneous Wireless Communications Services

     (c) Mandatory negotiations will commence for each BRS licensee when the AWS licensee informs the BRS
         licensee in writing of its desire to negotiate. Mandatory negotiations will be conducted with the goal of
         providing the BRS licensee with comparable facilities, defined as facilities possessing the following
         characteristics:

          (1) Throughput. Communications throughput is the amount of information transferred within a system in
              a given amount of time. System is defined as a base station and all end user units served by that
              base station. If analog facilities are being replaced with analog, comparable facilities may provide a
              comparable number of channels. If digital facilities are being replaced with digital, comparable
              facilities provide equivalent data loading bits per second (bps).

          (2) Reliability. System reliability is the degree to which information is transferred accurately within a
              system. Comparable facilities provide reliability equal to the overall reliability of the BRS system. For
              digital systems, reliability is measured by the percent of time the bit error rate (BER) exceeds a
              desired value, and for analog or digital video transmission, it is measured by whether the end-to-end
              transmission delay is within the required delay bound. If an analog system is replaced with a digital
              system, only the resulting frequency response, harmonic distortion, signal-to-noise ratio and its
              reliability will be considered in determining comparable reliability.

          (3) Operating Costs. Operating costs are the cost to operate and maintain the BRS system. AWS
              licensees would compensate BRS licensees for any increased recurring costs associated with the
              replacement facilities (e.g., additional rental payments, and increased utility fees) for five years after
              relocation. AWS licensees could satisfy this obligation by making a lump-sum payment based on
              present value using current interest rates. Additionally, the maintenance costs to the BRS licensee
              would be equivalent to the replaced system in order for the replacement system to be comparable.

     (d) AWS licensees are responsible for the relocation costs of end user units served by the BRS base station
         that is being relocated. If a lessee is operating under a BRS license, the BRS licensee may rely on the
         throughput, reliability, and operating costs of facilities in use by a lessee in negotiating comparable
         facilities and may include the lessee in negotiations.

§ 27.1252 Involuntary relocation procedures.
     (a) If no agreement is reached during the mandatory negotiation period, an AWS licensee may initiate
         involuntary relocation procedures under the Commission's rules. AWS licensees are obligated to pay to
         relocate BRS systems to which the AWS system poses an interference problem. Under involuntary
         relocation, the BRS licensee is required to relocate, provided that the AWS licensee:

          (1) Guarantees payment of relocation costs, including all engineering, equipment, site and FCC fees, as
              well as any legitimate and prudent transaction expenses incurred by the BRS licensee that are
              directly attributable to an involuntary relocation, subject to a cap of two percent of the “hard” costs
              involved. Hard costs are defined as the actual costs associated with providing a replacement
              system, such as equipment and engineering expenses. There is no cap on the actual costs of
              relocation. AWS licensees are not required to pay BRS licensees for internal resources devoted to the
              relocation process. AWS licensees are not required to pay for transaction costs incurred by BRS
              licensees during the mandatory period once the involuntary period is initiated, or for fees that cannot
              be legitimately tied to the provision of comparable facilities; and

          (2) Completes all activities necessary for implementing the replacement facilities, including engineering
              and cost analysis of the relocation procedure and, if radio facilities are used, identifying and
              obtaining, on the incumbents' behalf, new microwave frequencies and frequency coordination.

Miscellaneous Wireless Communications Services

     (b) Comparable facilities. The replacement system provided to an incumbent during an involuntary relocation
         must be at least equivalent to the existing BRS system with respect to the following three factors:

          (1) Throughput. Communications throughput is the amount of information transferred within a system in
              a given amount of time. System is defined as a base station and all end user units served by that
              base station. If analog facilities are being replaced with analog, the AWS licensee is required to
              provide the BRS licensee with a comparable number of channels. If digital facilities are being
              replaced with digital, the AWS licensee must provide the BRS licensee with equivalent data loading
              bits per second (bps). AWS licensees must provide BRS licensees with enough throughput to satisfy
              the BRS licensee's system use at the time of relocation, not match the total capacity of the BRS
              system.

          (2) Reliability. System reliability is the degree to which information is transferred accurately within a
              system. AWS licensees must provide BRS licensees with reliability equal to the overall reliability of
              their system. For digital data systems, reliability is measured by the percent of time the bit error rate
              (BER) exceeds a desired value, and for analog or digital video transmissions, it is measured by
              whether the end-to-end transmission delay is within the required delay bound.

          (3) Operating costs. Operating costs are the cost to operate and maintain the BRS system. AWS
              licensees must compensate BRS licensees for any increased recurring costs associated with the
              replacement facilities (e.g., additional rental payments, increased utility fees) for five years after
              relocation. AWS licensees may satisfy this obligation by making a lump-sum payment based on
              present value using current interest rates. Additionally, the maintenance costs to the BRS licensee
              must be equivalent to the replaced system in order for the replacement system to be considered
              comparable.

     (c) AWS licensees are responsible for the relocation costs of end user units served by the BRS base station
         that is being relocated. If a lessee is operating under a BRS license, the AWS licensee shall on the
         throughput, reliability, and operating costs of facilities in use by a lessee at the time of relocation in
         determining comparable facilities for involuntary relocation purposes.

     (d) Twelve-month trial period. If, within one year after the relocation to new facilities, the BRS licensee
         demonstrates that the new facilities are not comparable to the former facilities, the AWS licensee must
         remedy the defects or pay to relocate the BRS licensee to one of the following: Its former or equivalent 2
         GHz channels, another comparable frequency band, a land-line system, or any other facility that satisfies
         the requirements specified in paragraph (b) of this section. This trial period commences on the date that
         the BRS licensee begins full operation of the replacement system. If the BRS licensee has retained its 2
         GHz authorization during the trial period, it must return the license to the Commission at the end of the
         twelve months.

§ 27.1253 Sunset provisions.
     (a) BRS licensees will maintain primary status in the 2150–2160/62 MHz band unless and until an AWS
         licensee requires use of the spectrum. AWS licensees are not required to pay relocation costs after the
         relocation rules sunset (i.e. fifteen years from the date the first AWS license is issued in the band). Once
         the relocation rules sunset, an AWS licensee may require the incumbent to cease operations, provided
         that the AWS licensee intends to turn on a system within interference range of the incumbent, as
         determined by § 27.1255. AWS licensee notification to the affected BRS licensee must be in writing and
         must provide the incumbent with no less than six months to vacate the spectrum. After the six-month

Miscellaneous Wireless Communications Services

          notice period has expired, the BRS licensee must turn its license back into the Commission, unless the
          parties have entered into an agreement which allows the BRS licensee to continue to operate on a
          mutually agreed upon basis.

     (b) If the parties cannot agree on a schedule or an alternative arrangement, requests for extension will be
         accepted and reviewed on a case-by-case basis. The Commission will grant such extensions only if the
         incumbent can demonstrate that:

          (1) It cannot relocate within the six-month period (e.g., because no alternative spectrum or other
              reasonable option is available); and

          (2) The public interest would be harmed if the incumbent is forced to terminate operations.

§ 27.1254 Eligibility.
     (a) BRS licensees with primary status in the 2150–2162 MHz band as of June 23, 2006, will be eligible for
         relocation insofar as they have facilities that are constructed and in use as of this date.

     (b) Future licensing and modifications. After June 23, 2006, all major modifications to existing BRS systems in
         use in the 2150–2160/62 MHz band will be authorized on a secondary basis to AWS systems, unless the
         incumbent affirmatively justifies primary status and the incumbent BRS licensee establishes that the
         modification would not add to the relocation costs of AWS licensees. Major modifications include the
         following:

          (1) Additions of new transmit sites or base stations made after June 23, 2006;

          (2) Changes to existing facilities made after June 23, 2006, that would increase the size or coverage of
              the service area, or interference potential, and that would also increase the throughput of an existing
              system (e.g., sector splits in the antenna system). Modifications to fully utilize the existing
              throughput of existing facilities (e.g., to add customers) will not be considered major modifications
              even if such changes increase the size or coverage of the service area, or interference potential.

§ 27.1255 Relocation criteria for Broadband Radio Service licensees in the 2150–2160/62 MHz
band.
     (a) An AWS licensee in the 2150–2160/62 MHz band, prior to initiating operations from any base or fixed
         station that is co-channel to the 2150–2160/62 MHz band, must relocate any incumbent BRS system that
         is within the line of sight of the AWS licensee's base or fixed station. For purposes of this section, a
         determination of whether an AWS facility is within the line of sight of a BRS system will be made as
         follows:

          (1) For a BRS system using the 2150–2160/62 MHz band exclusively to provide one-way transmissions
              to subscribers, the AWS licensee will determine whether there is an unobstructed signal path (line of
              sight) to the incumbent licensee's geographic service area (GSA), based on the following criteria: use
              of 9.1 meters (30 feet) for the receiving antenna height, use of the actual transmitting antenna height
              and terrain elevation, and assumption of 4/3 Earth radius propagation conditions. Terrain elevation
              data must be obtained from the U.S. Geological Survey (USGS) 3-second database. All coordinates
              used in carrying out the required analysis shall be based upon use of NAD–83.

          (2) For all other BRS systems using the 2150–2160/62 MHz band, the AWS licensee will determine
              whether there is an unobstructed signal path (line of sight) to the incumbent licensee's receive
              station hub using the method prescribed in “Methods for Predicting Interference from Response
              Station Transmitters and to Response Station Hubs and for Supplying Data on Response Station

operations.

Link to an amendment published at 89 FR 7243, Feb. 1, 2024.

     (a) Licensees authorized to operate wireless services in the 600 MHz band must cause no harmful
         interference to public reception of the signals of broadcast television stations transmitting co-channel or
         on an adjacent channel.

           (1) Such wireless operations must comply with the D/U ratios in Table 5 in OET Bulletin No. 74,
               Methodology for Predicting Inter-Service Interference to Broadcast Television from Mobile Wireless
               Broadband Services in the UHF Band ([DATE]) (“OET Bulletin No. 74”). Copies of this document are
               available on the FCC's website. See https://www.fcc.gov/general/oet-bulletins-line.

           (2) If a 600 MHz band licensee causes harmful interference within the noise-limited contour or protected
               contour of a broadcast television station that is operating co-channel or on an adjacent channel, the
               600 MHz band licensee must eliminate the harmful interference.

     (b) A licensee authorized to operate wireless services in the 600 MHz downlink band:

           (1) Is not permitted to deploy wireless base stations within the noise-limited contour or protected
               contour of a broadcast television station licensed on a co-channel or adjacent channel in the 600
               MHz downlink band;

           (2) Is required to perform an interference study using the methodology in OET Bulletin No. 74 before
               deploying or operating wireless base stations within the culling distances specified in Tables 7–12
               of OET Bulletin No. 74 from the noise-limited contour or protected contour of such a broadcast
               television station;

           (3) Is required to perform an interference study using the methodology in OET Bulletin No. 74 when
               modifying a base station within the culling distances in Tables 7–12 of OET Bulletin 74 that results in
               an increase in energy in the direction of co-channel or adjacent channel broadcast television station's
               contours;

           (4) Is required to maintain records of the latest OET Bulletin No. 74 study for each base station and make
               them available for inspection to the Commission and, upon a claim of harmful interference, to the
               requesting broadcasting television station.

     (c) A licensee authorized to operate wireless services in the 600 MHz uplink band must limit its service area
         so that mobile and portable devices do not transmit:

           (1) Co-channel or adjacent channel to a broadcast television station within that station's noise-limited
               contour or protected contour;

           (2) Co-channel to a broadcast television station within five kilometers of that station's noise-limited
               contour or protected contour; and

           (3) Adjacent channel to a broadcast television station within 500 meters of that station's noise-limited
               contour or protected contour.

Miscellaneous Wireless Communications Services

          (3) Incumbent earth station. An incumbent earth station for this subpart is defined as an earth station
              that is entitled to interference protection pursuant to § 25.138(c) of this chapter. An incumbent earth
              station must transition above 4000 MHz pursuant to this subpart. An incumbent earth station will be
              able to continue receiving uninterrupted service both during and after the transition.

          (4) Earth station migration. Earth station migration includes any necessary changes that allow the
              uninterrupted reception of service by an incumbent earth station on new frequencies in the upper
              portion of the band, including, but not limited to retuning and repointing antennas, “dual illumination”
              during which the same programming is simultaneously downlinked over the original and new
              frequencies, and the installation of new equipment or software at earth station uplink and/or
              downlink locations for customers identified for technology upgrades necessary to facilitate the
              repack, such as compression technology or modulation.

          (5) Earth station filtering. A passband filter must be installed at the site of each incumbent earth station
              at the same time or after it has been migrated to new frequencies to block signals from adjacent
              channels and to prevent harmful interference from licensees in the 3.7 GHz Service. Earth station
              filtering can occur either simultaneously with, or after, the earth station migration, or can occur at
              any point after the earth station migration so long as all affected earth stations in a given Partial
              Economic Area and surrounding areas are filtered prior to a licensee in the 3.7 GHz Service
              commencing operations.

          (6) Contiguous United States (CONUS). For the purposes of the rules established in this subpart,
              contiguous United States consists of the contiguous 48 states and the District of Columbia as
              defined by Partial Economic Areas Nos. 1–41, 43–211, 213–263, 265–297, 299–359, and 361–411,
              which includes areas within 12 nautical miles of the U.S. Gulf coastline (see § 27.6(m)). In this
              context, the rest of the United States includes the Honolulu, Anchorage, Kodiak, Fairbanks, Juneau,
              Puerto Rico, Guam-Northern Mariana Islands, U.S. Virgin Islands, American Samoa, and the Gulf of
              Mexico PEAs.

          (7) Relocation Payment Clearinghouse. A Relocation Payment Clearinghouse is a neutral, independent
              third-party to administer the cost management for the transition of the 3700–4000 MHz band from
              the Fixed Satellite Service and Fixed Service to the 3.7 GHz Service.

          (8) Relocation Coordinator. A Relocation Coordinator is a third party that will ensure that all incumbent
              space station operators are relocating in a timely matter, and that is selected consistent with §
              27.1413. The Relocation Coordinator will have technical experience in understanding and working on
              earth stations and will manage the migration and filtering of incumbent earth stations of eligible
              space station operators that decline accelerated relocation payment.

§ 27.1412 Transition Plan.
     (a) Relocation deadlines. Eligible space station operators are responsible for all necessary actions to clear
         their transponders from the 3700–4000 MHz band (e.g., launching new satellites, reprogramming
         transponders, exchanging customers) and to migrate the existing services of incumbent earth stations in
         CONUS to the 4000–4200 MHz band (unless the incumbent earth station opts out of the formal
         relocation process, per paragraph (e) of this section), as of December 5, 2025. Eligible space station
         operators that fail to do so will be in violation of the conditions of their license authorization and
         potentially subject to forfeitures and other sanctions.

     (b) Accelerated relocation deadlines. An eligible space station operator shall qualify for accelerated relocation
         payments by completing an early transition of the band to the 3.7 GHz Service.

47 CFR 27.1412(b) (enhanced display)                                                                    page 215 of 240

Miscellaneous Wireless Communications Services

           (1) Phase I deadline. An eligible space station operator shall receive an accelerated relocation payment
               if it clears its transponders from the 3700–3820 MHz band and migrates all associated incumbent
               earth stations in CONUS above 3820 MHz no later than December 5, 2021 (Phase I deadline). To
               satisfy the Phase I deadline, an eligible space station operator must also provide passband filters to
               block signals from the 3700–3820 MHz band on all associated incumbent earth stations in PEAs
               1–4, 6–10, 12–19, 21–41, and 43–50 no later than December 5, 2021 (see § 27.6(m)). If an eligible
               space station operator receives an accelerated relocation payment for meeting this deadline, it must
               also satisfy the second early clearing deadline of December 5, 2023.

           (2) Phase II deadline. An eligible space station operator shall receive an accelerated relocation payment
               if it clears its transponders from the 3700–4000 MHz band and migrates incumbent earth stations in
               CONUS above 4000 MHz no later than December 5, 2023 (Phase II deadline). To satisfy the Phase II
               deadline, an eligible space station operator must also provide passband filters on all associated
               incumbent earth stations in CONUS no later than December 5, 2023.

           (3) Transition delays. An eligible space station operator shall not be held responsible for circumstances
               beyond their control related to earth station migration or filtering.

                (i)   An eligible space station operator must submit a notice of any incumbent earth station
                      transition delays to the Wireless Telecommunications Bureau within 7 days of discovering an
                      inability to accomplish the assigned earth station transition task. Such a request must include
                      supporting documentation to allow for resolution as soon as practicable and must be
                      submitted before the accelerated relocation deadlines.

                (ii) [Reserved]

           (4) Responsibility for meeting accelerated relocation deadlines. An eligible space station operator's
               satisfaction of the accelerated relocation deadlines shall be determined on an individual basis.

     (c) Accelerated relocation election. An eligible space station operator may elect to receive accelerated
         relocation payments to transition the 3700–4000 MHz band to the 3.7 GHz Service according to the
         Phase I and Phase II deadlines via a written commitment by filing an accelerated relocation election in GN
         Docket No. 18–122 no later than May 29, 2020.

           (1) The Wireless Telecommunications Bureau will prescribe the precise form of such election via Public
               Notice no later than May 12, 2020.

           (2) Each eligible space station operator that that makes an accelerated relocation election will be
               required, as part of its filing of this accelerated relocation election, to commit to paying the
               administrative costs of the Clearinghouse until the Commission awards licenses to the winning
               bidders in the auction, at which time those administrative costs will be repaid to those space station
               operators.

     (d) Transition Plan. Eligible space station operators must file with the Commission in GN Docket No. 18–122
         no later than June 12, 2020, a Transition Plan that describes the actions that must be taken to clear
         transponders on space stations and to migrate and filter earth stations. Eligible space station operators
         must make any necessary updates or resolve any deficiencies in their individual Transition Plans by
         August 14, 2020.

           (1) The Transition Plan must detail the eligible space station operator's individual timeline and
               necessary actions for clearing its transponders from the 3700–4000 MHz band, including:

47 CFR 27.1412(d)(1) (enhanced display)                                                                 page 216 of 240

Miscellaneous Wireless Communications Services

                (i)   All existing space stations with operations that will need to be transitioned to operations above
                      4000 MHz;

                (ii) The number of new satellites, if any, that the space station operator will need to launch in order
                     to maintain sufficient capacity post-transition, including detailed descriptions of why such new
                     satellites are necessary;

                (iii) The specific grooming plan for migrating existing services above 4000 MHz, including the pre-
                      and post-transition frequencies that each customer will occupy;

                (iv) Any necessary technology upgrades or other solutions, such as video compression or
                     modulation, that the space station operator intends to implement;

                (v) The number and location of incumbent earth stations antennas currently receiving the space
                    station operator's transmissions that will need to be transitioned above 4000 MHz;

                (vi) An estimate of the number and location of incumbent earth station antennas that will require
                     retuning and/or repointing in order to receive content on new transponder frequencies post-
                     transition; and

               (vii) The specific timeline by which the space station operator will implement the actions described
                     in its plan including any commitments to satisfy an early clearing.

          (2) To the extent that incumbent earth stations are not accounted for in eligible space station operators'
              Transition Plans, the Relocation Coordinator must prepare an Earth Station Transition Plan for such
              incumbent earth stations and may require each associated space station operator to file the
              information needed for such a plan with the Relocation Coordinator.

                (i)   Where space station operators do not elect to clear by the accelerated relocation deadlines and
                      therefore are not responsible for earth station relocation, the Earth Station Transition Plan must
                      provide timelines that ensure all earth station relocation is completed no later than the
                      relocation deadline.

                (ii) The Relocation Coordinator will describe and recommend the respective responsibility of each
                     party for earth station migration and filtering obligations in the Earth Station Transition Plan
                     and assist incumbent earth stations in transitioning including, for example, by installing filters
                     or hiring a third party to install such filters to the extent necessary.

     (e) Incumbent earth station opt-out. An incumbent earth station within the contiguous United States may opt
         out of the formal relocation process and accept a lump sum payment equal to the estimated reasonable
         transition costs of earth station migration and filtering, as determined by the Wireless
         Telecommunications Bureau, in lieu of actual relocation costs. Such an incumbent earth station is
         responsible for coordinating with the relevant space station operator as necessary and performing all
         relocation actions on its own, including switching to alternative transmission mechanisms such as fiber,
         and it will not receive further reimbursement for any costs exceeding the lump sum payment. An
         incumbent earth station electing to opt out must inform the appropriate space station operator(s) and the
         Relocation Coordinator that earth station migration and filtering will not be necessary for the relevant
         earth station site and must coordinate with operators to avoid any disruption of video and radio
         programming.

     (f) Space station status reports. On a quarterly basis, beginning December 31, 2020: Each eligible space
         station operator must provide a status report of its clearing efforts. Eligible space station operators may
         file joint status reports.

Miscellaneous Wireless Communications Services

     (g) Certification of accelerated relocation. Each eligible space station operator must file a timely certification
         that it has completed the necessary clearing actions to satisfy each accelerated relocation deadline. The
         certification must be filed once the eligible space station operator completes its obligations but no later
         than the applicable accelerated relocation deadline. The Wireless Telecommunication Bureau will
         prescribe the form of such certification.

           (1) The Bureau, Clearinghouse, and relevant stakeholders will have the opportunity to review the
               certification of accelerated relocation and identify potential deficiencies. The Wireless
               Telecommunications Bureau will prescribe the form of any challenges by relevant stakeholders as to
               the validity of the certification and will establish the process for how such challenges will impact the
               incremental decreases in the accelerated relocation payment as set- forth in § 27.1422(d).

           (2) If credible challenges as to the space station operator's satisfaction of the relevant deadline are
               made, the Bureau will issue a public notice identifying such challenges and will render a final
               decision as to the validity of the certification no later than 60 days from its filing. Absent notice from
               the Bureau of any such deficiencies within 30 days of the filing of the certification, the certification of
               accelerated relocation will be deemed validated.

     (h) Delegated authority. The Wireless Telecommunications Bureau is delegated the role of providing
         clarifications or interpretations to eligible space station operators of the Commission's orders for all
         aspects of the transition.

§ 27.1413 Relocation Coordinator.
     (a) Search committee. If eligible space station operators elect to receive accelerated relocation payments no
         later than May 29, 2020, so that a supermajority (80%) of accelerated relocation payments are accepted,
         each such electing eligible space station operator shall be eligible to appoint one member to a search
         committee that will seek proposals for a third-party with technical experience in understanding and
         working on earth stations to serve as a Relocation Coordinator and to manage the migration and filtering
         of incumbent earth stations of eligible space station operators that decline accelerated relocation
         payment.

           (1) The search committee should proceed by consensus; however, if a vote on selection of a Relocation
               Coordinator is required, it shall be by a supermajority (80%).

                 (i)   The search committee shall notify the Commission of its choice of Relocation Coordinator.

                (ii) The Wireless Telecommunications Bureau shall issue a Public Notice inviting comment on
                     whether the entity selected satisfies the criteria established in paragraph (b) of this section and
                     issue a final order announcing whether the criteria has been satisfied;

                (iii) Should the Wireless Telecommunications Bureau be unable to find the criteria have been
                      satisfied, the selection process will start over and the search committee will submit a new
                      proposed entity.

           (2) If eligible space station operators select a Relocation Coordinator, they shall be responsible for
               paying its costs.

           (3) In the event that the search committee fails to select a Relocation Coordinator and to notify the
               Commission by July 31, 2020, or in the case that at least 80% of accelerated relocation payments
               are not accepted (and thus accelerated relocation is not triggered):

                 (i)   The search committee will be dissolved without further action by the Commission.

                (ii) The Commission will initiate a procurement of a Relocation Coordinator to facilitate the
                     transition. Specifically, the Office of the Managing Director will initiate the procurement, and the
                     Wireless Telecommunications Bureau will take all other necessary actions to meet the
                     accelerated relocation deadlines (to the extent applicable to any given operator) and the
                     relocation deadline.

                (iii) In the case that the Wireless Telecommunications Bureau selects the Relocation Coordinator,
                      overlay licensees will, collectively, pay for the services of the Relocation Coordinator and staff.
                      The Relocation Coordinator shall submit its own reasonable costs to the Relocation
                      Clearinghouse, who will then collect payments from overlay licensees. It shall also provide
                      additional financial information as requested by the Bureau to satisfy the Commission's
                      oversight responsibilities and/or agency specific/government-wide reporting obligations.

§ 27.1414 Relocation Payment Clearinghouse.
A Relocation Payment Clearinghouse shall be selected and serve to administer the cost-related aspects of the
transition in a fair, transparent manner, pursuant to Commission rules and oversight, to mitigate financial disputes
among stakeholders, and to collect and distribute payments in a timely manner for the transition of the 3700–4000
MHz band to the 3.7 GHz Service.

     (a) Selection process.

          (1) A search committee will select the Relocation Payment Clearinghouse. The search committee shall
              consist of member appointed by each of following nine entities: ACA Connects, Intelsat, SES,
              Eutelsat S.A., National Association Broadcasters, National Cable Television Association, CTIA,
              Competitive Carriers Association, and WISPA.

          (2) The search committee shall convene no later than June 22, 2020 and shall notify the Commission of
              the detailed selection criteria for the position of Relocation Payment Clearinghouse no later than
              June 1, 2020. Such criteria must be consistent with the qualifications, roles, and duties of the
              Relocation Payment Clearinghouse specified in this subpart. The Wireless Telecommunications
              Bureau (Bureau) is directed, on delegated authority, to issue a Public Notice notifying the public that
              the search committee has published criteria, outlining submission requirements, and providing the
              closing dates for the selection of the Relocation Payment Clearinghouse and source (i.e., web page).

          (3) The search committee should proceed by consensus; however, if a vote on selection of a Relocation
              Payment Clearinghouse is required, it shall be by a majority.

          (4) In the event that the search committee fails to select a Relocation Payment Clearinghouse and to
              notify the Commission by July 31, 2020, the search committee will be dissolved without further
              action by the Commission. In the event that the search committee fails to select a Clearinghouse
              and to notify the Commission by July 31, 2020, two of the nine members of the search committee
              will be dropped therefrom by lot, and the remaining seven members of the search committee shall
              select a Clearinghouse by majority vote by August 14, 2020.

                                                                                                      47 CFR 27.1414(a)(5)
Miscellaneous Wireless Communications Services

           (5) During the course of the Relocation Payment Clearinghouse's tenure, the Commission will take such
               measures as are necessary to ensure timely compliance, including, should it become necessary,
               issuing subsequent public notices to select new Relocation Payment Clearinghouses(s).

     (b) Selection criteria.

           (1) The Relocation Payment Clearinghouse must be a neutral, independent entity with no conflicts of
               interest (organizational or personal) on the part of the organization or its officers, directors,
               employees, contractors, or significant subcontractors.

                 (i)   Organizational conflicts of interest means that because of other activities or relationships with
                       other entities, the Relocation Payment Clearinghouse, its contractors, or significant
                       subcontractors are unable or potentially unable to render impartial services, assistance or
                       advice; the Relocation Payment Clearinghouse's objectivity in performing its function is or
                       might be otherwise impaired; or the Relocation Payment Clearinghouse might gain an unfair
                       competitive advantage.

                (ii) Personal conflict of interest means a situation in which an employee, officer, or director of the
                     Relocation Payment Clearinghouse, the Relocation Payment Clearinghouse's contractors or
                     significant subcontractors has a financial interest, personal activity, or relationship that could
                     impair that person's ability to act impartially and in the best interest of the transition when
                     performing their assigned role, or is engaged in self-dealing.

           (2) The Relocation Payment Clearinghouse must be able to demonstrate that it has the requisite
               expertise to perform the duties required, which will include collecting and distributing relocation and
               accelerated relocation payments, auditing incoming and outgoing estimates, mitigating cost
               disputes among parties, and generally acting as clearinghouse.

           (3) The search committee should ensure that the Relocation Payment Clearinghouse meets relevant
               best practices and standards in its operation to ensure an effective and efficient transition. First, the
               Relocation Payment Clearinghouse should be required, in administering the transition, to:

                 (i)   Engage in strategic planning and adopt goals and metrics to evaluate its performance;

                (ii) Adopt internal controls for its operations;

                (iii) Utilize enterprise risk management practices; and

                (iv) Use best practices to protect against improper payments and to prevent fraud, waste and abuse
                     in its handling of funds. The Relocation Payment Clearinghouse must be required to create
                     written procedures for its operations, using the Government Accountability Office's Green Book
                     to serve as a guide in satisfying such requirements.

           (4) The search committee must also ensure that the Relocation Payment Clearinghouse adopts robust
               privacy and data security best practices in its operations, given that it will receive and process
               information critical to ensuring a successful and expeditious transition.

                 (i)   When the prohibition in § 1.2105(c) of this chapter applies to competitive bidding for licenses in
                       the 3.7 GHz service, the Relocation Payment Clearinghouse must make real time disclosures of
                       the content and timing of and the parties to communications, if any, from or to applicants to
                       participate in the competitive bidding, as defined by § 1.2105(c)(5)(i) of this chapter.

Miscellaneous Wireless Communications Services

                (ii) The Relocation Payment Clearinghouse should also comply with, on an ongoing basis, all
                     applicable laws and Federal Government guidance on privacy and information security
                     requirements such as relevant provisions in the Federal Information Security Management Act,
                     National Institute of Standards and Technology publications, and Office of Management and
                     Budget guidance.

                (iii) The Relocation Payment Clearinghouse must hire a third-party firm to independently audit and
                      verify, on an annual basis, the Relocation Payment Clearinghouse's compliance with privacy and
                      information security requirements and to provide recommendations based on any audit
                      findings; to correct any negative audit findings and adopt any additional practices suggested by
                      the auditor; and to report the results to the Bureau.

     (c) Reports and information.

          (1) The Relocation Payment Clearinghouse must provide quarterly reports that detail the status of
              reimbursement funds available for clearing obligations, the relocation and accelerated relocation
              payments issued, the amounts collected from overlay licensees, and any certifications filed by
              incumbents. The reports must account for all funds spent to transition the 3.7 GHz Service Band,
              including the Relocation Payment Clearinghouse's own expenses, e.g., salaries and fees paid to law
              firms, accounting firms, and other consultants. The report shall include descriptions of any disputes
              and the manner in which they were resolved.

          (2) The Relocation Payment Clearinghouse shall provide to the Office of the Managing Director and the
              Wireless Telecommunications Bureau, by March 1 of each year, an audited statement of funds
              expended to date, including salaries and expenses of the Clearinghouse.

          (3) The Relocation Clearing House shall provide to the Wireless Telecommunications Bureau additional
              information upon request.

§ 27.1415 Documentation of expenses.
Parties seeking reimbursement of compensable relocation costs must document their actual expenses and the
Relocation Payment Clearinghouse, or a third-party on behalf of the Relocation Payment Clearinghouse, may
conduct audits of entities that receive reimbursements. Entities receiving reimbursements must make available all
relevant documentation upon request from the Relocation Payment Clearinghouse or its contractor.

§ 27.1416 Reimbursable costs.
     (a) Determining reimbursable costs. The Relocation Payment Clearinghouse shall review reimbursement
         requests to determine whether they are reasonable and to ensure they comply with the requirements
         adopted in this sub-part. The Relocation Payment Clearinghouse shall give parties the opportunity to
         supplement any reimbursement claims that the Relocation Payment Clearinghouse deems deficient.
         Reimbursement submissions that fall within the estimated range of costs in the cost category schedule
         issued by the Wireless Telecommunications Bureau shall be presumed reasonable. If the Relocation
         Payment Clearinghouse determines that the amount sought for reimbursement is unreasonable, it shall
         notify the party of the amount it deems eligible for reimbursement. The Wireless Telecommunications
         Bureau shall make further determinations related to reimbursable costs, as necessary, throughout the
         transition process.

Miscellaneous Wireless Communications Services

     (b) Payment procedures. Following a determination of the reimbursable amount, the Relocation Payment
         Clearinghouse shall incorporate approved claims into invoices, which it shall issue to each licensee
         indicating the amount to be paid. The Relocation Payment Clearinghouse shall pay approved claims
         within 30 days of invoice submission. The Relocation Payment Clearinghouse shall also include its own
         reasonable costs in the invoices.

§ 27.1417 Reimbursement fund.
The Relocation Payment Clearinghouse will establish and administer an account that will fund the costs for the
transition of this band to the 3.7 GHz Service after an auction for the 3.7 GHz Service concludes. Licensees in the
3.7 GHz Service shall pay their pro rata share of six months' worth of estimated transition costs into a
reimbursement fund, administered by the Relocation Payment Clearinghouse, shortly after the auction and then
every six months until the transition is complete. The Relocation Payment Clearinghouse shall draw from the
reimbursement fund to pay approved, invoiced claims, consistent with § 27.1418. If the reimbursement fund does
not have sufficient funds to pay approved claims before a six-month replenishment, the Relocation Payment
Clearinghouse shall provide 3.7 GHz Service licensees with 30 days' notice of the additional pro rata shares they
must contribute. At the end of the transition, the Relocation Payment Clearinghouse shall refund any unused
amounts to 3.7 GHz Service licensees according to their pro rata shares.

§ 27.1418 Payment obligations.
     (a) Each eligible space station operator is responsible for the payment of its own satellite transition costs
         until the auction winners have been announced.

     (b) Licensees in the 3.7 GHz Service shall pay their pro rata share of:

          (1) The reasonable costs of the Relocation Payment Clearinghouse and, in the event the Wireless
              Telecommunications Bureau selects the Relocation Coordinator, the services of the Relocation
              Coordinator and its staff;

          (2) The actual relocation costs, provided that they are not unreasonable, for eligible space station
              operators and incumbent fixed service licensees; the actual transition costs, provided they are not
              unreasonable, associated with the necessary migration and filtering of incumbent earth stations;

          (3) Any lump sum payments, if elected by incumbent earth station operators in lieu of actual relocation
              costs; and

          (4) Specified accelerated relocation payments for space station operators that clear on an accelerated
              timeframe. Licensees in the 3.7 GHz Service shall be responsible for the full costs of space station
              transition, the Relocation Payment Clearinghouse, and, if selected and established by the Wireless
              Telecommunications Bureau, the Relocation Coordinator, based on their pro rata share of the total
              auction bids of each licensee's gross winning bids in the auction overall; they shall be responsible for
              incumbent earth station and incumbent fixed service transition costs in a Partial Economic Area
              based on their pro rata share of the total gross bids for that Partial Economic Area.

     (c) Following the auction, and every six months until the close of the transition, licensees in the 3.7 GHz
         Service shall submit their portion of estimated transition costs to a reimbursement fund, and the
         Relocation Payment Clearinghouse will reimburse parties incurring transition costs. If actual costs exceed
         estimated costs, the Relocation Payment Clearinghouse shall perform a true-up for additional funds from
         3.7 GHz Service licensees.

     (d) If 3.7 GHz band license is relinquished to the Commission prior to all relocation cost reimbursements and
         accelerated relocation payments being paid, the remaining payments will be distributed among other
         similarly situated 3.7 GHz band licensees. If a new license is issued for the previously relinquished rights
         prior to final payments becoming due, the new 3.7 GHz band licensee will be responsible for the same pro
         rata share of relocation costs and accelerated relocation payments as the initial 3.7 GHz band license. If a
         3.7 GHz band licensee sells its rights on the secondary market, the new 3.7 GHz band licensee will be
         obligated to fulfill all payment obligations associated with the license.

§ 27.1419 Lump sum payment for earth station opt out.
The Wireless Telecommunications Bureau shall announce a lump sum that will be available per each incumbent
earth station that elects to opt out from the formal relocation process, per § 27.1412(e), as well as the process for
electing lump sum payments. Incumbent earth station owners must make the lump sum payment election no later
than 30 days after the Bureau announces the lump sum payment amounts, and must indicate whether each
incumbent earth station for which it elects the lump sum payment will be transitioned to the upper 200 megahertz
in order to maintain C-band services or will discontinue C-band services.

§ 27.1420 Cost-sharing formula.
     (a) For space station transition and Relocation Payment Clearinghouse costs, and in the event the Wireless
         Telecommunications Bureau selects a Relocation Coordinator pursuant to § 27.1413(a), Relocation
         Coordinator costs, the pro rata share of each flexible-use licensee will be the sum of the final clock phase
         prices (P) for the set of all license blocks that a bidder wins divided by the total final clock phase prices
         for all N license blocks sold in the auction. To determine a licensee's reimbursement obligation (RO), that
         pro rata share would then be multiplied by the total eligible reimbursement costs (RC). Mathematically,
         this is represented as:

     (b) For incumbent earth stations and fixed service incumbent licensee transition costs, a flexible-use
         licensee's pro rata share will be determined on a PEA-specific basis, based on the final clock phase prices
         for the license blocks it won in each PEA. To calculate the pro rata share for incumbent earth station
         transition costs in a given PEA, the same formula identified in § 27.1412(a) will be used, except I is the set
         of licenses a bidder won in the PEA, N is the total blocks sold in the PEA and RC is the PEA-specific earth
         station and fixed service relocation costs.

     (c) For the Phase I accelerated relocation payments, the pro rata share of each flexible use licensee of the 3.7
         to 3.8 MHz in the 46 PEAs that are cleared by December 5, 2021, will be the sum of the final clock phase
         prices (P) that the licensee won divided by the total final clock phase prices for all M license blocks sold in
         those 46 PEAs. To determine a licensee's RO the pro rata share would then be multiplied by the total
         accelerated relocation payment due for Phase I, A1. Mathematically, this is represented as:

     (d) For Phase II accelerated relocation payments, the pro rata share of each flexible use licensee will be the
         sum of the final clock phase prices (P) that the licensee won in the entire auction, divided by the total final
         clock phase prices for all N license blocks sold in the auction. To determine a licensee's RO the pro rata
         share would then be multiplied by the total accelerated relocation payment due for Phase II, A2.

§ 27.1421 Disputes over costs and cost-sharing.
     (a) Parties disputing a cost estimate, cost invoice, or payment or cost-sharing obligation must file an
         objection with the Relocation Payment Clearinghouse.

     (b) The Relocation Payment Clearinghouse may mediate any disputes regarding cost estimates or payments
         that may arise in the course of band reconfiguration; or refer the disputant parties to alternative dispute
         resolution fora.

           (1) Any dispute submitted to the Relocation Payment Clearinghouse, or other mediator, shall be decided
               within 30 days after the Relocation Payment Clearinghouse has received a submission by one party
               and a response from the other party.

           (2) Thereafter, any party may seek expedited non-binding arbitration, which must be completed within 30
               days of the recommended decision or advice of the Relocation Payment Clearinghouse or other
               mediator.

           (3) The parties will share the cost of this arbitration if it is before the Relocation Payment Clearinghouse.

     (c) Should any issues still remain unresolved, they may be referred to the Bureau within ten days of
         recommended decision or advice of the Relocation Payment Clearinghouse or other mediator and any
         decision of the Relocation Payment Clearinghouse can be appealed to the Chief of the Bureau.

           (1) When referring an unresolved matter, the Relocation Payment Clearinghouse shall forward the entire
               record on any disputed issues, including such dispositions thereof that the Relocation Payment
               Clearinghouse has considered.

           (2) Upon receipt of such record and advice, the Bureau will decide the disputed issues based on the
               record submitted. The Bureau is directed to resolve such disputed issues or designate them for an
               evidentiary hearing before an Administrative Law Judge. If the Bureau decides an issue, any party to
               the dispute wishing to appeal the decision may do so by filing with the Commission, within ten days
               of the effective date of the initial decision, a Petition for de novo review; whereupon the matter will be
               set for an evidentiary hearing before an Administrative Law Judge.

           (3) Parties seeking de novo review of a decision by the Bureau are advised that, in the course of the
               evidentiary hearing, the Commission may require complete documentation relevant to any disputed
               matters; and, where necessary, and at the presiding judge's discretion, require expert engineering,
               economic or other reports or testimony. Parties may therefore wish to consider possibly less
               burdensome and expensive resolution of their disputes through means of alternative dispute
               resolution.

§ 27.1423 Protection of incumbent operations.
     (a) To protect incumbent earth stations from out-of-band emissions from fixed stations, base stations and
         mobiles, the power flux density (PFD) of any emissions within the 4000–4200 MHz band must not exceed
         −124 dBW/m2/MHz as measured at the earth station antenna.

     (b) To protect incumbent earth stations from blocking, the power flux density (PFD) of any emissions within
         the 3700–3980 MHz band must not exceed −16 dBW/m2/MHz as measured at the earth station antenna.

     (c) All 3.7 GHz Service licensees, prior to initiating operations from any base or fixed station, must coordinate
         cochannel frequency usage with all incumbent Telemetry, Tracking, and Command (TT&C) earth stations
         within a 70 km radius. The licensee must ensure that the aggregated power from its operations meets an
         interference to noise ratio (I/N) of −6 dB to the TT&C earth station receiver. A base station's operation will
         be defined as cochannel when any of the 3.7 GHz Service licensee's authorized frequencies are separated
         from the center frequency of the TT&C earth station by less than 150% of the maximum emission
         bandwidth in use by the TT&C earth station.

     (d) All 3.7 GHz Service licensees operating on an adjacent channel to an incumbent TT&C earth station must
         ensure that the aggregated power from its operations meets an interference to noise ratio (I/N) of −6 dB
         to the TT&C earth station receiver.

     (e) To protect incumbent TT&C earth stations from blocking, the power flux density (PFD) of any emissions
         within the 3700–3980 MHz band must not exceed −16 dBW/m2/MHz as measured at the TT&C earth
         station antenna.

§ 27.1424 Agreements between 3.7 GHz Service licensees and C-Band earth station operators.
The PFD limits in § 27.1423 may be modified by the private agreement of licensees of 3.7 GHz Service and entities
operating earth stations in the 4000–4200 MHz band or TT&C operations in the 3700–3980 MHz band. A licensee
of the 3.7 GHz Service who is a party to such an agreement must maintain a copy of the agreement in its station
files and disclose it, upon request, to prospective license assignees, transferees, or spectrum lessees, and to the
Commission.

                          channels.

                (ii) Descriptions of the agreements between the prospective broadband licensee and all covered
                     incumbents collectively holding licenses for at least 90% of site-channels within the county and
                     within 70 miles of the county boundary, and geographically licensed channels where the license
                     area completely or partially overlaps the county.

                (iii) Descriptions in detail of all information and actions necessary to accomplish the realignment,
                      as follows:

                     (A) The applications that the parties to the agreements will file for spectrum in the
                         narrowband segment in order to relocate or repack licensees;

                     (B) A description of how the applicant will provide interference protection to, and/or acquire or
                         relocate from the broadband segment covered incumbents collectively holding licenses
                         for at least 90% of site-channels within 70 miles of the county and within 70 miles of the
                         county boundary and/or evidence that it holds licenses for the site-channels and/or
                         geographically licensed channels.

                     (C) Any rule waivers or other actions necessary to implement an agreement with a covered
                         incumbent; and

                     (D) Such additional information as may be required.

                (iv) A certification from an FCC-certified frequency coordinator that the Transition Plan's
                     representations can be implemented consistent with Commission rules. The certification must
                     establish that the relocations proposed therein take into consideration all relevant covered
                     incumbents and are consistent with the existing part 90 interference protection criteria if the
                     covered incumbent is site-based, and include any private contractual agreements between the
                     prospective broadband licensee and a geographically-licensed covered incumbent.

           (4) Applicants seeking to transition multiple counties may simultaneously file a single Transition Plan
               with each of its county-based applications.

     (c) Anti-windfall provisions.

           (1) The applicant must return to the Commission all of its licensed 900 MHz SMR and B/ILT spectrum,
               up to six megahertz, for the county in which it seeks a broadband license. The applicant will be
               required to file, within 15 days of filing its broadband license application, an application(s) to cancel
               all of its 900 MHz SMR and B/ILT spectrum, up to six megahertz, conditioned upon Commission
               grant of its application.

Miscellaneous Wireless Communications Services

          (2) If the applicant relinquishes less than six megahertz of spectrum in accordance with paragraph
              (c)(1) of this section, then the applicant must remit an anti-windfall payment prior to the grant of the
              900 MHz broadband license. Payment must be made through a monetary payment to the U.S.
              Treasury.

§ 27.1504 Mandatory relocation.
     (a) Subject to paragraph (b) of this section, broadband licensees may require mandatory relocation from the
         broadband segment covered incumbents' remaining site-channels in a given county and within 70 miles
         of the county boundary, and geographically licensed channels where the license area completely or
         partially overlaps the county, that were not covered by § 27.1503(a)(2).

     (b) Complex systems are exempt from mandatory relocation. To qualify as exempt from mandatory
         relocation, a complex system must have at least one site (of its 45 or more functionally integrated sites)
         located within the county license area or within 70 miles of the county boundary.

     (c) A broadband licensee seeking to relocate a covered incumbent pursuant to this section is required to pay
         all reasonable relocation costs, including providing the relocated covered incumbent with comparable
         facilities. To be comparable, the replacement system provided to a covered incumbent during a
         mandatory relocation must be at least equivalent to the existing 900 MHz system with respect to the
         following four factors:

          (1) System;

          (2) Capacity;

          (3) Quality of service; and

          (4) Operating costs.

     (d) Having met the 90% success threshold, a 900 MHz broadband licensee seeking to trigger the mandatory
         relocation process shall serve notice on applicable covered incumbent(s).

     (e) Following the service of notice, a 900 MHz broadband licensee may request information from the covered
         incumbent reasonably required to craft its offer of comparable facilities.

     (f) We expect all parties to negotiate with the utmost “good faith” in the negotiation process. Factors relevant
         to a “good-faith” determination include:

          (1) Whether the party responsible for paying the cost of band reconfiguration has made a bona fide offer
              to relocate the incumbent to comparable facilities;

          (2) The steps the parties have taken to determine the actual cost of relocation to comparable facilities;
              and

          (3) Whether either party has unreasonably withheld information, essential to the accurate estimation of
              relocation costs and procedures, requested by the other party.

     (g) A party seeking Commission resolution of a dispute must submit in writing to the Chief, Wireless
         Telecommunications Bureau:

          (1) The name, address, telephone number, and email address of the 900 MHz broadband licensee or
              covered incumbent making the allegation;

          (2) The name of the 900 MHz broadband licensee or covered incumbent about which the allegation is
              made;

           (3) A complete statement of the facts supporting the broadband licensee's or incumbent's claim; and

           (4) The specific relief sought.

     (h) If an incumbent fails to negotiate in good faith, its facilities may be mandatorily relocated, and its license
         modified accordingly by the Commission pursuant to section 316 of the Act. If the Wireless
         Telecommunications Bureau finds bad faith on the part of the broadband licensee, the broadband
         licensee may lose the right to relocate the incumbent or the Wireless Telecommunications Bureau may
         refer the matter to the Enforcement Bureau for action (which could include a range of sanctions, such as
         imposition of forfeitures).

§ 27.1505 Performance requirements.
     (a) 900 MHz broadband licensees shall demonstrate compliance with performance requirements by filing a
         construction notification with the Commission, within 15 days of the expiration of the applicable
         benchmark, in accordance with the provisions set forth in § 1.946(d) of this chapter.

           (1) The licensee must certify whether it has met the applicable performance requirements. The licensee
               must file a description and certification of the areas for which it is providing service. The
               construction notifications must include electronic coverage maps and supporting technical
               documentation regarding the type of service it is providing for each licensed area within its service
               territory and the type of technology used to provide such service, and certify the accuracy of such
               documentation. Supporting documentation must include the assumptions used to create the
               coverage maps, including the propagation model and the signal strength necessary to provide
               reliable service with the licensee's technology.

           (2) To demonstrate compliance with the population coverage requirement, licensees shall use the most
               recently available decennial U.S. Census Bureau data at the time of measurement and shall base
               their measurements of population served on areas no larger than the Census Tract level. The
               population within a specific Census Tract (or other acceptable identifier) will be deemed served by
               the licensee only if it provides reliable signal coverage to and offers service within the specific
               Census Tract (or other acceptable identifier). To the extent the Census Tract (or other acceptable
               identifier) extends beyond the boundaries of a license area, a licensee with authorizations for such
               areas may include only the population within the Census Tract (or other acceptable identifier)
               towards meeting the performance requirement of a single, individual license.

     (b) A 900 MHz broadband licensee must meet either a population coverage requirement or geographic
         coverage as follows:

           (1) Population metric.

                 (i)   A 900 MHz broadband licensee shall provide reliable signal coverage and offer broadband
                       service to at least 45% of the population in its license area within six years of license grant.

                (ii) A 900 MHz broadband licensee shall provide reliable signal coverage and offer broadband
                     service to at least 80% of the population in its license area within 12 years of license grant.

           (2) Geographic coverage. Alternatively, a 900 MHz broadband licensee may:

                 (i)   Demonstrate it provides reliable signal coverage and offers broadband service covering at least
                       25% of the geographic license area within six years of license grant.

                (ii) Demonstrate it provides reliable signal coverage and offers broadband service covering at least
                     50% of the geographic license area within twelve years of license grant.

     (c) Penalties.

           (1) If a 900 MHz broadband licensee fails to meet the first performance benchmark, we require the
               licensee to meet the final performance benchmark two years sooner (i.e., at 10 years into the license
               term) and reduce the license term from 15 years to 13 years.

           (2) If a 900 MHz broadband licensee fails to meet the final performance benchmark, its authorization for
               that license area will terminate automatically without Commission action.

     (d) License renewal. After satisfying the 12-year, final performance benchmark, a licensee must continue to
         provide coverage and offer broadband service at or above that level for the remaining three years of the
         15-year license term in order to warrant license renewal.

§ 27.1506 Frequencies.
The 897.5–900.5 MHz and 936.5–939.5 MHz band segments are available for licensing with an authorized
bandwidth up to 3 megahertz paired channels. The 897.5–900.5 MHz segment must only be used for uplink
transmissions. The 936.5–939.5 MHz segments must only be used for downlink transmissions.

§ 27.1507 Effective radiated power limits for 900 MHz broadband systems.
     (a) Maximum ERP. The power limits specified in this section are applicable to operations in areas more than
         110 km (68.4 miles) from the U.S./Mexico border and 140 km (87 miles) from the U.S./Canada border.

           (1) General limit.

                 (i)   The ERP for base and repeater stations must not exceed 400 watts/megahertz power spectral
                       density (PSD) per sector and an antenna height of 304 m height above average terrain (HAAT),
                       except that antenna heights greater than 304 m HAAT are permitted if power levels are reduced
                       below 400 watts/megahertz ERP in accordance with Table 1 of this section.

                 (ii) Provided that they also comply with paragraphs (b) and (c) of this section, licensees are
                      permitted to operate base and repeater stations with up to a maximum ERP of 1000 watts/
                      megahertz power spectral density (PSD) per sector and an antenna height of 304 m height
                      above average terrain (HAAT), except that antenna heights greater than 304 m HAAT are
                      permitted if power levels are reduced below 1000 watts/megahertz ERP in accordance with
                      Table 2 of this section.

           (2) Rural areas. For systems that are located in counties with population densities of 100 persons or
               fewer per square mile, based upon the most recently available population statistics from the Bureau
               of the Census:

                 (i)   The ERP for base and repeater stations must not exceed 800 watts/megahertz power spectral
                       density (PSD) per sector and an antenna height of 304 m height above average terrain (HAAT),
                       except that antenna heights greater than 304 m HAAT are permitted if power levels are reduced
                       below 800 watts/megahertz ERP in accordance with Table 3 of this section.

                 (ii) Provided that they also comply with paragraphs (b) and (c) of this section, base and repeater
                      stations may operate with up to a maximum ERP of 2000 watts/megahertz power spectral
                      density (PSD) per sector and an antenna height of 304 m height above average terrain (HAAT),
                      except that antenna heights greater than 304 m HAAT are permitted if power levels are reduced
                      below 2000 watts/megahertz ERP in accordance with Table 4 of this section.

          (3) Mobile, control and auxiliary test stations. Mobile, control and auxiliary test stations must not exceed
              10 watts ERP.

          (4) Portable stations. Portable stations must not exceed 3 watts ERP.

     (b) Power flux density (PFD). Each 900 MHz broadband base or repeater station that exceeds the ERP limit of
         paragraph (a)(1)(i) or (a)(2)(i) of this section must be designed and deployed so as not to exceed a
         modeled PFD of 3000 microwatts/m2/MHz over at least 98% of the area within 1 km of the base or
         repeater station antenna, at 1.6 meters above ground level. To ensure compliance with this requirement,
         the licensee must perform predictive modeling of the PFD values within at least 1 km of each base or
         repeater station antenna prior to commencing such operations and, thereafter, prior to making any site
         modifications that may increase the PFD levels around the base or repeater station. The modeling must
         take into consideration terrain and other local conditions and must use good engineering practices for the
         900 MHz band.

     (c) Power measurement. Measurement of 900 MHz broadband base transmitter and repeater ERP must be
         made using an average power measurement technique. Power measurements for base transmitters and
         repeaters must be made in accordance with either of the following:

          (1) A Commission-approved average power technique (see FCC Laboratory's Knowledge Database); or

          (2) For purposes of this section, peak transmit power must be measured over an interval of continuous
              transmission using instrumentation calibrated in terms of an rms-equivalent voltage. The
              measurement results shall be properly adjusted for any instrument limitations, such as detector
              response times, limited resolution bandwidth capability when compared to the emission bandwidth,
              sensitivity, etc., so as to obtain a true peak measurement for the emission in question over the full
              bandwidth of the channel.

     (d) PAR limit. The peak-to-average ratio (PAR) of the transmission must not exceed 13 dB.

     (e) Height-power limit. As specified in paragraph (a) of this section, the following tables specify the maximum
         base station power for antenna heights above average terrain (HAAT) that exceed 304 meters.

§ 27.1509 Emission limits.
The power of any emission outside a licensee's frequency band(s) of operation shall be attenuated below the
transmitter power (P) in watts by at least the following amounts:

     (a) For 900 MHz broadband operations in 897.5–900.5 MHz band by at least 43 + 10 log (P) dB.

     (b) For 900 MHz broadband operations in the 936.5–939.5 MHz band, by at least 50 + 10 log (P) dB.

     (c) Compliance with the provisions of paragraphs (a) and (b) of this section is based on the use of
         measurement instrumentation employing a resolution bandwidth of 100 kHz or greater. However, in the
         100 kHz bands immediately outside and adjacent to the licensee's band, a resolution bandwidth of at
         least 1 percent of the emission bandwidth of the fundamental emission of the transmitter may be
         employed. The emission bandwidth is defined as the width of the signal between two points, one below
         the carrier center frequency and one above the carrier center frequency, outside of which all emissions are
         attenuated at least 26 dB below the transmitter power.

     (d) The measurements of emission power can be expressed in peak or average values, provided they are
         expressed in the same parameters as the transmitter power.

     (e) When an emission outside of the authorized bandwidth causes harmful interference, the Commission
         may, at its discretion, require greater attenuation than specified in this section.

§ 27.1602 Incumbent Federal operations.
Regarding incumbent Federal operations in the 3450–3550 MHz band, 3.45 GHz Service licensees must comply
with footnote US431B of the Table of Frequency Allocations in 47 CFR 2.106.

§ 27.1603 Coordination procedures.
     (a) Coordination requirement. Prior to operation of any 3.45 GHz Service license in a Cooperative Planning
         Area or Periodic Use Area, a 3.45 GHz Service licensee must successfully coordinate such operation with
         any Federal incumbents in the Cooperative Planning Area or Periodic Use Area. The coordination
         procedures contained in this section shall apply unless the 3.45 GHz Service licensee and the Federal
         incumbent(s) have reached a mutually acceptable operator-to-operator coordination agreement that
         provides otherwise.

     (b) Informal discussions. Before a 3.45 GHz Service licensee submits a formal coordination request, it may
         share and discuss draft proposals with Federal incumbent coordination staff. These discussions are
         voluntary, informal, and non-binding and can begin at any time.

     (c) Formal coordination. The 3.45 GHz Service licensee shall initiate coordination by formally requesting
         access to operate within a Cooperative Planning Area and/or Periodic Use Area directly through the
         Department of Defense's online portal.

     (d) Initiation, timing, and affirmative concurrence. A 3.45 GHz Service licensee must initiate a formal
         coordination request through the online portal provided by the Department of Defense. Unless otherwise
         agreed between a 3.45 GHz Service licensee and the relevant Federal incumbent(s), no formal
         coordination requests may be submitted until nine (9) months after the date of the auction closing Public
         Notice. 3.45 GHz Service licensees may request informal discussions (through the point of contact
         identified in the applicable Transition Plan) during this nine-month time period. Unless otherwise agreed
         to in writing, the requirement to reach a coordination arrangement is satisfied only by obtaining the
         affirmative concurrence of the relevant Federal incumbent(s) via the portal. The requirement of this
         paragraph (d) is not satisfied by omission.

     (e) Submission information. To submit a formal coordination request, the 3.45 GHz Service licensee must
         include information about the technical characteristics for the 3.45 GHz Service base stations and
         associated mobile units relevant to operation within the Cooperative Planning Area and/or Periodic Use
         Area. This information should be provided in accordance with the instructions provided in the portal user's
         guide provided by the Department of Defense. 3.45 GHz Service licensees must prioritize their
         deployments in the Cooperative Planning Area for each Federal incumbent when submitting a formal

Miscellaneous Wireless Communications Services

          coordination request. If a 3.45 GHz Service licensee is seeking to coordinate with multiple systems or
          multiple locations of operation controlled by one Federal incumbent, the licensee must specify the order
          in which it prefers the Federal incumbent process the request (i.e., the order of systems or geographic
          locations).

     (f) Coordination analysis. If a 3.45 GHz Service licensee has questions about the result of a coordination
         request, it may contact the Federal incumbent to propose network design modifications to help address
         issues raised by the Federal incumbent. Once the 3.45 GHz Service licensee has revised its network
         design, it must resubmit a formal coordination request, and the 3.45 GHz Service formal coordination
         process begins again.

     (g) Interference resolution process. In instances of identified harmful interference occurring between a
         Federal and non-Federal operator not otherwise addressed by the coordination procedures or operator-to-
         operator agreements, the 3.45 GHz Service licensee shall first attempt to resolve the interference directly.
         If that effort is unsuccessful, the 3.45 GHz Service licensee, if adversely affected may escalate the matter
         to the Commission.

§ 27.1604 Reimbursement of relocation expenses of non-Federal radiolocation incumbents.
     (a) Relocation reimbursement contribution. Each entity granted an initial license (not a renewal) in the 3.45
         GHz Service (Licensee) must pay a pro rata portion to reimburse the costs incurred by authorized non-
         Federal, secondary radiolocation licensees for relocating from the 3.3–3.55 GHz band. These costs
         include the cost of a clearinghouse's administration of the reimbursement, which the radiolocation
         licensees will pay initially and include in their reimbursable costs.

     (b) Pro rata share. A Licensee's pro rata share of relocation costs will be determined by dividing the total
         actual costs of such relocation, as approved by the clearinghouse selected pursuant to § 27.1605, by the
         total number of 3.45 GHz Service licenses granted, multiplied by the number of such licenses the
         Licensee will hold.

     (c) Timing of payment. A Licensee's relocation reimbursement contribution share must be paid to the
         clearinghouse by the date(s) and subject to procedures specified by public notice.

§ 27.1605 Reimbursement clearinghouse.
     (a) The clearinghouse ultimately selected shall determine the reimbursement obligations of each Licensee
         pursuant to § 27.1604.

          (1) The clearinghouse must be a must be a neutral, independent entity with no conflicts of interest (as
              defined in § 27.1414(b), on the part of the organization or its officers, directors, employees,
              contractors, or significant subcontractors.

          (2) The clearinghouse must be able to demonstrate that it has the requisite expertise to perform the
              duties required, which will include collecting and distributing reimbursement payments, auditing
              incoming and outgoing estimates, mitigating cost disputes among parties, and generally acting as a
              clearinghouse.

          (3) The clearinghouse must comply with, on an ongoing basis, all applicable laws and Federal
              Government guidance on privacy and information security requirements such as relevant provisions
              in the Federal Information Security Management Act, National Institute of Standards and Technology
              publications, and Office of Management and Budget guidance.

          (4) The clearinghouse must provide quarterly reports to the Wireless Telecommunications Bureau that
              detail the status of reimbursement funds available, the payments issued, the amounts collected
              from licensees, and any information filed by incumbents. The reports must account for all funds
              spent, including the clearinghouse's own expenses. The report shall include descriptions of any
              disputes and the manner in which they were resolved.

     (b) Non-Federal secondary radiolocation licensees in the 3.3–3.55 GHz band that seek reimbursement of
         their expenses for relocating operations authorized under their licenses and existing as of February 22,
         2019, must submit invoices or other appropriate documentation of such expenses to the clearinghouse
         no later than a date to be specified by public notice.

     (c) Expenses must be reasonably related to the relocation from the 3.3–3.55 GHz band to the 2.9–3.0 GHz
         band, may be future expenses or expenses already incurred—including the clearinghouse's costs, and no
         expenses for other purposes will be subject to reimbursement. Ineligible expenses include, but are not
         limited to, those related to upgrades or improvements. The clearinghouse shall have the authority to
         determine whether particular expenses are eligible for reimbursement.

     (d) The Wireless Telecommunications Bureau is responsible for resolving any disputes arising from decisions
         by the clearinghouse and shall specify by public notice when the clearinghouse's responsibilities have
         terminated.

§ 27.1606 Aggregation of 3450–3550 MHz band licenses.
     (a) 3.45 GHz Service licensees may aggregate up to 40 megahertz of 3450–3550 MHz band licenses across
         both license categories in any service area at any given time for four years after the close of the auction.
         After four years post-auction, no such aggregation limit on 3450–3550 MHz licenses shall apply.

     (b) The criteria in § 20.22(b) of this chapter will apply in order to attribute partial ownership and other
         interests for the purpose of applying the aggregation limit in paragraph (a) of this section.

§ 27.1607 Information sharing for time division duplex synchronization.
     (a) 3.45 GHz Service licensees must provide information to requesting Citizens Broadband Radio Service
         (part 96 of this chapter) operators to enable time division duplex (TDD) synchronization. Negotiations
         over the information must be conducted in good faith, with the goal of enabling synchronization between
         the relevant systems.

          (1) A Citizens Broadband Radio Service operator, whether a Priority Access Licensee or a General
              Authorized Access user (§ 96.1(b) of this chapter), may request information from a 3.45 GHz Service
              licensee to enable cross-service TDD synchronization if it provides service, or intends to provide
              service, in the same or adjacent geographic area as a 3.45 GHz Service licensee.

          (2) Upon request by an eligible Citizens Broadband Radio Service operator, the 3.45 GHz Service licensee
              must provide sufficient technical information to allow the Citizens Broadband Radio Service operator
              to synchronize its system with the 3.45 GHz band system. The 3.45 GHz Service licensee must keep
              this information current if its network operations change.

     (b) 3.45 GHz Service licensees are under no obligation to make any changes to their operations or proposed
         operations to enable TDD synchronization.
