Subpart A—General
§ 30.1 Creation of upper microwave flexible use service, scope and authority.
As of December 14, 2016, Local Multipoint Distribution Service licenses for the 27.5–28.35 GHz band, and licenses
issued in the 38.6–40 GHz band under part 101 of this chapter shall be reassigned to the Upper Microwave Flexible
Use Service. Local Multipoint Distribution Service licenses in bands other than 27.5–28.35 GHz shall remain in that
service and shall be governed by the part 101 of this chapter applicable to that service.

§ 30.2 Definitions.
The following definitions apply to this part:

    Authorized bandwidth. The maximum width of the band of frequencies permitted to be used by a station. This is
          normally considered to be the necessary or occupied bandwidth, whichever is greater. (See § 2.202 of this
          chapter).

    Authorized frequency. The frequency, or frequency range, assigned to a station by the Commission and specified
          in the instrument of authorization.

    Fixed satellite earth station. An earth station intended to be used at a specified fixed point.

    Local Area Operations. Operations confined to physical facility boundaries, such as a factory.

    Point-to-Multipoint Hub Station. A fixed point-to-multipoint radio station that provides one-way or two-way
           communication with fixed Point-to-Multipoint Service User Stations.

    Point-to-Multipoint Service. A fixed point-to-multipoint radio service consisting of point-to-multipoint hub
           stations that communicate with fixed point-to-multipoint user stations.

    Point-to-Multipoint User Station. A fixed radio station located at users' premises, lying within the coverage area
           of a Point-to-Multipoint Hub station, using a directional antenna to receive one-way communications from
           or providing two-way communications with a fixed Point-to-Multipoint Hub Station.

    Point-to-point station. A station that transmits a highly directional signal from a fixed transmitter location to a
           fixed receive location.

    Portable device. Transmitters designed to be used within 20 centimeters of the body of the user.

Upper Microwave Flexible Use Service

§ 30.103 License term.
Initial authorizations will have a term not to exceed ten years from the date of initial issuance or renewal.

§ 30.104 Performance requirements.
     (a) Upper Microwave Flexible Use Service licensees must make a buildout showing as part of their renewal
         applications. Licensees relying on mobile or point-to-multipoint service must show that they are providing
         reliable signal coverage and service to at least 40 percent of the population within the service area of the
         licensee, and that they are using facilities to provide service in that area either to customers or for internal
         use. Licensees relying on point-to-point service must demonstrate that they have four links operating and
         providing service, either to customers or for internal use, if the population within the license area is equal
         to or less than 268,000. If the population within the license area is greater than 268,000, a licensee relying
         on point-to-point service must demonstrate it has at least one link in operation and is providing service for
         each 67,000 population within the license area. In order to be eligible to be counted under the point-to-
         point buildout standard, a point-to-point link must operate with a transmit power greater than +43 dBm.

     (b) In the alternative, a licensee may make its buildout showing on the basis of geographic area coverage. To
         satisfy the requirements of using this metric, licensees relying on mobile or point-to-multipoint service
         must show that they are providing reliable signal coverage and service to at least 25% of the geographic
         area of the license. The geographic area of the license shall be determined by the total land area of the
         county or counties covered by the license. Licensees relying on fixed point-to-point links or other, low-
         power point-to-point connections must show that they have deployed at least one transmitter or receiver
         in at least 25% of the census tracts within the license area. All equipment relied upon in the showing,
         whatever type of service or connection it provides, must be operational and providing service, either to
         customers or for internal use, as of the date of the filing.

     (c) Showings that rely on a combination of multiple types of service will be evaluated on a case-by-case
         basis. Licensees may not combine population-based showings with geographic area-based showings.

     (d) If a licensee in this service is also a Fixed-Satellite Service licensee and uses the spectrum covered under
         its UMFUS license in connection with a satellite earth station, it can demonstrate compliance with the
         requirements of this section by demonstrating that the earth station in question is in service, operational,
         and using the spectrum associated with the license. This provision can only be used to demonstrate
         compliance for the county in which the earth station is located.

     (e) Failure to meet this requirement will result in automatic cancellation of the license. In bands licensed on a
         Partial Economic Area basis, licensees will have the option of partitioning a license on a county basis in
         order to reduce the population or land area within the license area to a level where the licensee's buildout
         would meet one of the applicable performance metrics.

     (f) Existing 24 GHz, 28 GHz and 39 GHz licensees shall be required to make a showing pursuant to this
         section by June 1, 2024.

Upper Microwave Flexible Use Service

§ 30.105 Geographic partitioning and spectrum disaggregation.
     (a) Parties seeking approval for partitioning and disaggregation shall request from the Commission an
         authorization for partial assignment of a license pursuant to § 1.948 of this chapter. Upper Microwave
         Flexible Use Service 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
               § 1.948 of this chapter 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) Spectrum may be disaggregated in any amount.

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

           (4) For purposes of partitioning and disaggregation, part 30 systems must be designed so as not to
               exceed the signal level specified for the particular spectrum block in § 30.204 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 § 30.103.

§ 30.203 Emission limits.
     (a) The conductive power or the total radiated power of any emission outside a licensee's frequency block
         shall be −13 dBm/MHz or lower. However, in the bands immediately outside and adjacent to the licensee's
         frequency block, having a bandwidth equal to 10 percent of the channel bandwidth, the conductive power
         or the total radiated power of any emission shall be −5 dBm/MHz or lower.

     (b)

           (1) Compliance with this provision is based on the use of measurement instrumentation employing a
               resolution bandwidth of 1 megahertz or greater.

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

           (3) The measurements of emission power can be expressed in peak or average values.

     (c) For fixed point-to-point and point-to-multipoint limits see § 30.404.

§ 30.204 Field strength limits.
     (a) Base/mobile operations: The predicted or measured Power Flux Density (PFD) from any Base Station

                  (i)   In any 1 MHz band, the center frequency of which is removed from the assigned frequency by
                        more than 50 percent up to and including 250 percent of the authorized bandwidth: As
                        specified by the following equation but in no event less than 11 decibels:

                        A = 11 + 0.4(P−50) + 10 Log10 B. (Attenuation greater than 56 decibels or to an absolute power
                        of less than −13 dBm/1MHz is not required.)
                 (ii) In any 1 MHz band, the center frequency of which is removed from the assigned frequency by
                      more than 250 percent of the authorized bandwidth: At least 43 + 10 Log10 (the mean output
                      power in watts) decibels, or 80 decibels, whichever is the lesser attenuation. The authorized
                      bandwidth includes the nominal radio frequency bandwidth of an individual transmitter/
                      modulator in block-assigned bands. Equipment licensed prior to April 1, 2005 shall only be
                      required to meet this standard in any 4 kHz band.

                 (iii) The emission mask in paragraph (a)(2)(i) of this section applies only to the band edge of each
                       block of spectrum, but not to subchannels established by licensees. The value of P in the
                       equation is the percentage removed from the carrier frequency and assumes that the carrier
                       frequency is the center of the actual bandwidth used. The emission mask can be satisfied by
                       locating a carrier of the subchannel sufficiently far from the channel edges so that the emission
                       levels of the mask are satisfied. The emission mask shall use a value B (bandwidth) of 40 MHz,
                       for all cases even in the case where a narrower subchannel is used (for instance the actual
                       bandwidth is 10 MHz) and the mean output power used in the calculation is the sum of the
                       output power of a fully populated channel. For block assigned channels, the out-of-band
                       emission limits apply only outside the assigned band of operation and not within the band.

§ 30.405 Transmitter power limitations.
On any authorized frequency, the average power delivered to an antenna in this service must be the minimum
amount of power necessary to carry out the communications desired. Application of this principle includes, but is
not to be limited to, requiring a licensee who replaces one or more of its antennas with larger antennas to reduce its
antenna input power by an amount appropriate to compensate for the increased primary lobe gain of the
replacement antenna(s). In no event shall the average equivalent isotropically radiated power (EIRP), as referenced
to an isotropic radiator, exceed the following:

                                    Maximum Allowable EIRP

§ 30.406 Directional antennas.
     (a) Unless otherwise authorized upon specific request by the applicant, each station authorized under the
         rules of this subpart must employ a directional antenna adjusted with the center of the major lobe of
         radiation in the horizontal plane directed toward the receiving station with which it communicates:
         provided, however, where a station communicates with more than one point, a multi- or omni-directional
         antenna may be authorized if necessary.

     (b) Fixed stations (other than temporary fixed stations) must employ transmitting and receiving antennas
         (excluding second receiving antennas for operations such as space diversity) meeting the appropriate
         performance Standard A indicated in the table to this section, except that in areas not subject to
         frequency congestion, antennas meeting performance Standard B may be used. For frequencies with a
         Standard B1 and a Standard B2, in order to comply with Standard B an antenna must fully meet either
         Standard B1 or Standard B2. Licensees shall comply with the antenna standards table shown in this
         paragraph in the following manner:

           (1) With either the maximum beamwidth to 3 dB points requirement or with the minimum antenna gain
               requirement; and

           (2) With the minimum radiation suppression to angle requirement.

2Stations authorized to operate in the 38,600–40,000 MHz band may use antennas other than those meeting the Category A standard. However, the
Commission may require the use of higher performance antennas where interference problems can be resolved by the use of such antennas.
