        Summary of Notice of Proposed Rulemaking
        1. In the Notice of Proposed Rulemaking (NPRM), the Commission proposed to amend parts 1, 2, 74, 78, 87, 90, and 97 of its rules to implement allocation decisions from the World Radiocommunication Conference (Geneva, 2007) (WRC-07) concerning portions of the radio frequency (RF) spectrum between 108 MHz and 20.2 GHz and to make certain updates to its rules in this frequency range. The NPRM follows the Commission's July 2010 WRC-07 Table Clean-up Order, which made certain non-substantive, editorial revisions to the Table of Frequency Allocations (Allocation Table) and to other related rules. The Commission also addressed the recommendations for implementation of the WRC-07 Final Acts that the National Telecommunications and Information Administration (NTIA) submitted to the Commission in August 2009. As part of its comprehensive review of the Allocation Table, the Commission also proposed to make allocation changes that are not related to the WRC-07 Final Acts and update certain service rules, and requested comment on other allocation issues that concern portions of the RF spectrum between 137.5 kHz and 54.25 GHz.
        2. Specifically, the Commission proposed to:
        • Raise the secondary amateur service allocation in the 1900-2000 kHz band to primary status, remove the Federal and non-Federal radiolocation service (RLS) allocations from this band, and remove this band from §§ 90.103, 97.301, and 97.303.

        • Allocate the 108-117.975 MHz band to the aeronautical mobile route (R) service (AM(R)S) on a primary basis for Federal/non-Federal shared use, limited to systems operating in accordance with recognized international aeronautical standards and Resolution 413 (Rev.WRC-07), and in the 108-112 MHz sub-band, to systems composed of ground-based transmitters and associated receivers that provide navigational information in support of air navigation functions. Further, the Commission proposed to prohibit the proposed AMR(R)S use from constraining the use of the 88-108 MHz band by stations in the broadcasting service (FM radio stations) operating in accordance with 47 CFR part 73.

        • Allocate the 156.4875-156.5125 MHz and 156.5375-156.5625 MHz bands to the fixed and land mobile services on a primary basis for non-Federal use, subject to not causing harmful interference to, nor claiming protection from, the maritime mobile VHF radiocommunication service, and with the licensing of this spectrum restricted to the area consisting of VHF Public Coast Station Areas 10-42. The NPRM also requested comment on whether additional areas can be licensed while fully protecting VHF Channel 70 reception.
        • Allocate the 156.5125-156.5375 MHz band to the maritime mobile service (MMS) on a primary basis for Federal and non-Federal use, restricted to the following types of operations: Distress, urgency, safety, and calling via Digital Selective Calling (DSC) techniques.
        • Make the frequencies 156.525 MHz and 156.8 MHz available for search and rescue (SAR) operations concerning manned space vehicles.
        • Make the frequency 156.3 MHz available for use by aircraft stations for the purpose of SAR operations and other safety-related communications, permit Federal ship and coast stations to operate on certain navigation frequencies (156.775 MHz and 156.825 MHz) on a primary basis, and simplify the U.S. Table by combining these proposed provisions with existing provisions in a new U.S. footnote (US52).

        • Allocate the 161.9625-161.9875 MHz (AIS 1) and 162.0125-162.0375 MHz (AIS 2) bands to the mobile-satellite service (MSS) on a secondary basis for Federal/non-Federal shared use for the reception of automatic identification system (AIS) emissions from stations operating in the maritime mobile service. The NPRM also solicited comment on whether the Commission should implement the WRC-12 allocation decisions with regard to the AIS 1 and AIS 2 bands, i.e., whether the Commission should allocate these bands to the aeronautical mobile (off-route) service (AM(OR)S) and the MSS (Earth-to-space) on a primary basis, restrict the use of these bands by the AM(OR)S to AIS emissions from SAR aircraft, and require that these operations not constrain the operation of allocated services in adjacent bands.
        • Amend the quiet zone rules in § 1.924(f) to reflect the areas listed in paragraph (a) of US270, limit its applicability to RLS systems, and move the revised text from paragraph (f) to paragraph (e).
        • Amend NG120 by revising “band 928-960 MHz” and “mobile operations” to “bands 928-929 MHz, 932-932.5 MHz, 941-941.5 MHz, and 952-960 MHz” and “associated mobile operations,” respectively, by deleting the phrase “as specified in 47 CFR part 101.”
        • Allocate the 960-1164 MHz band to the AM(R)S on a primary basis for Federal/non-Federal use to the 960-1164 MHz band and require that any AM(R)S systems operating in the 960-1164 MHz band not cause harmful interference to, claim protection from, or impose constraints on aeronautical radionavigation service (ARNS) systems operating in that band.
        • Remove the conditional secondary non-Federal fixed-satellite service (FSS) allocation from the 1390-1392 MHz and 1430-1432 MHz bands.
        • Delete the unused non-Federal aeronautical mobile telemetry (AMT) allocation in the 2310-2320 MHz band from US339 and remove non-Federal access to two unused frequencies (2312.5 MHz and 2352.5 MHz) that are available for telemetry or telecommand operations of expendable and reusable launch vehicles.
        • Update US203 to list the radio astronomy stations that observe in the 4800-4940 MHz and 14.47-14.5 GHz bands.

        • Allocate the 5091-5150 MHz band to the aeronautical mobile service on a primary basis for Federal/non-Federal shared use, restricted to surface applications at airports, AMT transmissions, and aeronautical security transmissions. The NPRM proposed to restrict AMT use of the 5091-5150 MHz band to the 52 flight test areas listed in new footnote US111, except that additional locations may be authorized on a case-by-case basis. The NPRM requested comment on whether aeronautical security transmissions should be excluded from the list of permitted uses. The NPRM proposed to remove the precedence that the Microwave Landing System (MLS) currently has over other uses of the 5091-5150 MHz band and to extend the date after which no new assignments may be made to earth stations providing feeder links for non-geostationary MSS systems to January 1, 2016.
        • Amend part 87 of the Commission's rules to bring the proposed AMT allocation in the 5091-5150 MHz band into immediate effect, remove all references to the 1525-1535 MHz and 2310-2345 MHz bands from part 87, and list the 2390-2395 MHz band in all appropriate rule sections.
        • Raise the secondary Federal RLS allocation in the 9000-9200 MHz and 9300-9500 MHz bands to primary status, allocate the 9300-9500 MHz band to the Earth exploration-satellite service (EESS) (active) and the space research service (SRS) (active) on a primary basis for Federal use, allocate the 9800-9900 MHz band to the EESS (active) and SRS (active) on a secondary basis for Federal use, require that the use of these proposed allocations not cause harmful interference to existing primary operations, and limit active sensor use of the 9300-9500 MHz band to systems requiring more than 300 MHz of bandwidth.

        • Allocate the 9300-9500 MHz and 9800-9900 MHz bands to the EESS (active) and the SRS (active) on a secondary basis for non-Federal use. The NPRM solicited comment on whether there is a non-Federal requirement for primary EESS (active) and SRS (active) allocations in the 9300-9500 MHz band.

        • Amend US401 and §§ 1.924, 74.32, and 78.19 of the Commission's rules by adding coordination areas in San Miguel, California and Guam for terrestrial operations in the 17.7-19.7 GHz band, consistent with a request by NTIA. The NPRM also proposed to amend US334 to limit primary Federal earth stations in the 17.8-18.3 GHz and 19.3-19.7 GHz sub-bands to the Denver, Colorado; Washington, DC; San Miguel, California; and Guam areas.

        • Amend §§ 1.924, 74.32, and 78.19 to bring better consistency between these rules and to update these rules, e.g., to remove the Morrison, Colorado location from § 78.19. The NPRM sought comment on whether the coordination requirements for Multichannel Video Programming Distributors (MVPD) operations in § 74.32, and references in § 1.924 to MVPD operations pursuant to parts 74 and 78, should be removed from the Commission's rules.
        • Allocate the 18-18.1 GHz band to the meteorological-satellite service for space-to-Earth transmission on a primary basis.

        • Update the list of radio astronomy stations in US388 that observe in the 81-86 GHz, 92-94 GHz, and 94.1-95 GHz bands by removing the Five Colleges Radio Observatory and by adding the Heinrich Hertz Submillimeter Observatory, which is located at Mount Graham, Arizona. The NPRM proposed to require coordination within 150 kilometers of the new observatory at Mount Graham.
        • Implement WRC-07's mandatory unwanted emission limits in the 22.55-23.55 GHz band for all new NGSO inter-satellite service systems, and requested comment on how these limits should apply to the incumbent licensees system on a going-forward basis.

        • Implement WRC-07's mandatory unwanted emission limits for non-Federal FSS earth stations that transmit in the 49.7-50.2 GHz and 50.4-50.9 GHz bands. The NPRM sought comment on how adoption of these mandatory unwanted emission limits for earth stations transmitting in the 49.7-50.2 GHz band will affect the implementation of the Commission's band plan for the 36-51.4 GHz band (V-band) and on whether and how these provisions should apply to existing licensees in these bands.

        • Urge licensees of fixed stations in the 31-31.3 GHz band to limit the maximum elevation angle of the antenna main beam to 20° and to employ automatic transmitter power control (ATPC). The NPRM solicits comment on whether the Commission should adopt WRC-07's mandatory unwanted emission limit for the 31-31.3 GHz band or whether an alternative emission limit would be sufficient. The NRPM also requested comment on whether the aeronautical mobile service allocation should be removed from the 31-31.3 GHz band.
        • Implement WRC-07's mandatory unwanted emission limits for future non-Federal fixed stations that transmit in the 51.4-52.6 GHz band.
        • Urge operators in the 1390-1395 MHz and 1427-1452 MHz bands to comply with the non-mandatory unwanted emission levels specified in ITU Resolution 750 (except that Wireless Medical Telemetry Service devices would be excluded).

        • Revise US265 by removing the phrase “per 250 kHz,” by adding the advisory language for fixed point-to-point systems, and by prohibiting point-to-multipoint use of the 10.6-10.68 GHz band. The NPRM also proposed to urge licensees to employ ATPC and to permit licensees holding a valid authorization as of the effective date of the Report and Order in this proceeding to continue to operate as authorized. The NPRM requested comment on whether the Commission should: (1) Prohibit fixed stations with main beam elevation angles greater than 20° from transmitting on frequencies in the 10.6-10.68 GHz band; (2) require fixed stations (using paired frequencies) to transmit on frequencies in the 10.6-10.68 GHz band using the lower elevation angle; (3) require the use of ATPC; (4) raise the maximum equivalent isotropically radiated power (EIRP) limit from 40 to 48 dBW; and (5) urge licensees to limit the off-axis EIRP above 20° to −10 dBW.
        • Implement the spectrum sharing criteria adopted at WRC-07 for the 36-37 GHz band (which is not currently licensed by the Commission).
        • Renumber various footnotes in accordance with Commission policy, to replace various placeholder footnotes with the international footnotes adopted at WRC-07, remove duplicative rule/unneeded text, correct grammatical/typographical errors in the Commission's rules, and otherwise update the Commission's rules.
        3. In addition, the Commission solicited comment on whether it should:
        • Allocate the 135.7-137.8 kHz band to the amateur radio service on a secondary basis, with amateur stations restricted to an EIRP of 1 watt and required to protect power line carrier (PLC) operations.
        • Remove a lightly-used primary non-Federal AMT allocation in the 2345-2360 MHz band and an unused primary radionavigation service (RNS) allocation from the 24.75-25.05 GHz band. If the Commission decides to remove the RNS allocation from the 24.75-25.05 GHz band, then it would amend NG167 by employing the international footnote 5.535 text in the 24.75-25.05 GHz band, remove the Part 87 cross reference from the Allocation Table, and remove the 24.75-25.05 GHz band from §§ 87.173(b) and 87.187(x).
        Initial Regulatory Flexibility Analysis
        4. As required by the Regulatory Flexibility Act of 1980, as amended (RFA),1

           the Commission has prepared this present Initial Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on small entities by the policies and rules proposed in this NPRM. Written public comments are requested on this IRFA. Comments must be identified as responses to the IRFA and must be filed by the deadlines specified in the NPRM for comments. The Commission will send a copy of this NPRM, including this IRFA, to the Chief Counsel for Advocacy of the Small Business Administration (SBA).2
           In addition, the NPRM and IRFA (or summaries thereof) will be published in the Federal Register.3

            1 See 5 U.S.C. 603. The RFA, see 5 U.S.C. 601-612, has been amended by the Small Business Regulatory Enforcement Fairness Act of 1996, (SBREFA) Pub. L. No. 104-121, Title II, 110 Stat. 857 (1996).

        A. Need for, and Objectives of, the Proposed Rules

        5. The Commission proposed to amend parts 1, 2, 74, 78, 87, 90, and 97 of its rules to implement allocation decisions from the World Radiocommunication Conference (Geneva, 2007) (WRC-07) concerning the radio frequency (RF) spectrum between 108 MHz and 20.2 GHz and otherwise make certain updates to its rules in this frequency range. The rules proposed in this NPRM affect the frequency bands and radio services discussed in section D, below.
        B. Legal Basis
        6. The proposed action is authorized under sections 1, 4, 301, 302(a), and 303(b), (c), and (f) of the Communications Act of 1934, as amended, 47 U.S.C. 151, 154, 301, 302(a), and 303(b), (c), and (f).
        C. Description and Estimate of the Number of Small Entities to Which the Proposed Rule Will Apply
        7. The RFA directs agencies to provide a description of and, where feasible, an estimate of, the number of small entities that may be affected by the proposed rules, if adopted.4
           The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.” 5
           In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act.6
           A “small business concern” is one which: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the Small Business Administration (SBA).7

            4 5 U.S.C. 603(b)(3).

            5 5 U.S.C. 601(6).

            6 5 U.S.C. 601(3) (incorporating by reference the definition of “small-business concern” in the Small Business Act, 15 U.S.C. 632). Pursuant to 5 U.S.C. 601(3), the statutory definition of a small business applies “unless an agency, after consultation with the Office of Advocacy of the Small Business Administration and after opportunity for public comment, establishes one or more definitions of such term which are appropriate to the activities of the agency and publishes such definition(s) in the Federal Register.”

            7 15 U.S.C. 632.

        Small Businesses, Small Organizations, and Small Governmental Jurisdictions. Our action may, over time, affect small entities that are not easily categorized at present. We therefore describe here, at the outset, three comprehensive, statutory small entity size standards.8
           First, nationwide, there are a total of approximately 27.5 million small businesses, according to the SBA.9
           In addition, a “small organization” is generally “any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.” 10
           Nationwide, as of 2007, there were approximately 1,621,315 small organizations.11
           Finally, the term “small governmental jurisdiction” is defined generally as “governments of cities, towns, townships, villages, school districts, or special districts, with a population of less than fifty thousand.” 12
           Census Bureau data for 2011 indicate that there were 89,476 local governmental jurisdictions in the United States.13
           We estimate that, of this total, as many as 88,506 entities may qualify as “small governmental jurisdictions.” 14
           Thus, we estimate that most governmental jurisdictions are small.

            8 See 5 U.S.C. 601(3)-(6).

            12 5 U.S.C. 601(5).

            13 U.S. Census Bureau, Statistical Abstract of the United States: 2011, Table 427 (2007).

            14 The 2007 U.S. Census data for small governmental organizations are not presented based on the size of the population in each such organization. There were 89,476 small governmental organizations in 2007. If we assume that county, municipal, township, and school district organizations are more likely than larger governmental organizations to have populations of 50,000 or less, the total of these organizations is 52,125. If we make the same assumption about special districts and also assume that special districts are different from county, municipal, township, and school districts, in 2007 there were 37,381 special districts. Therefore, of the 89,476 small governmental organizations documented in 2007, as many as 89,506 may be considered small under the applicable standard. This data may overestimate the number of such organizations that has a population of 50,000 or less. U.S. CENSUS BUREAU, STATISTICAL ABSTRACT OF THE UNITED STATES 2011, Tables 427, 426 (Data cited therein are from 2007).

        Amateur Radio Service. Because “small entities,” as defined in the RFA, are not persons eligible for licensing in the amateur service, this proposed rule does not apply to “small entities.” Rather, it applies exclusively to individuals who are the control operators of amateur radio stations.
        Satellite Telecommunications and All Other Telecommunications. Two economic census categories address the satellite industry. The first category has a small business size standard of $15 million or less in average annual receipts, under SBA rules.15
           The second has a size standard of $25 million or less in annual receipts.16

            15 13 CFR 121.201, North American Industry Classification System (“NAICS”) code 517410.

            16 13 CFR 121.201, NAICS code 517919.

        The category of Satellite Telecommunications “comprises establishments primarily engaged in providing telecommunications services to other establishments in the telecommunications and broadcasting industries by forwarding and receiving communications signals via a system of satellites or reselling satellite telecommunications.” 17
           Census Bureau data for 2007 show that 512 Satellite Telecommunications firms operated for that entire year.18
           Of this total, 464 firms had annual receipts of under $10 million, and 18 firms had receipts of $10 million to $24,999,999.19
           Consequently, the Commission estimates that the majority of Satellite Telecommunications firms are small entities that might be affected by our action.

        The second category, i.e. “All Other Telecommunications” comprises “establishments primarily engaged in providing specialized telecommunications services, such as satellite tracking, communications telemetry, and radar station operation. This industry also includes establishments primarily engaged in providing satellite terminal stations and associated facilities connected with one or more terrestrial systems and capable of transmitting telecommunications to, and receiving telecommunications from, satellite systems. Establishments providing Internet services or voice over Internet protocol (VoIP) services via client-supplied telecommunications connections are also included in this industry.” 20
           For this category, Census Bureau data for 2007 show that there were a total of 2,383 firms that operated for the entire year.21
           Of this total, 2,347 firms had annual receipts of under $25 million and 12 firms had annual receipts of $25 million to $49, 999,999.22
           Consequently, the Commission estimates that the majority of All Other Telecommunications firms are small entities.

        D. Description of Projected Reporting, Record Keeping, and Other Compliance Requirements
        8. In the following paragraphs, we describe the proposals and their expected impact on small entities. First, we describe the proposed deletion of unused non-Federal allocations. Second, we describe all other proposed changes. We request comment on our analysis.
        9. Deletion of Unused Allocations. The NPRM proposed to delete the following unused allocations: (1) the radiolocation service (RLS) from the 1900-2000 kHz band; (2) the fixed-satellite service (FSS) from the 1390-1392 MHz and 1430-1432 MHz bands; and (3) the aeronautical mobile service (AMS) (telemetry) from the 2310-2320 MHz band. Because there are no licensees operating stations in the aforementioned radiocommunication services and frequency bands, the proposed deletions will have no impact on small entities.
        10. The NPRM also solicited comment on deleting the aeronautical mobile service allocation from the 31-31.3 GHz band. Because there is no part 87 equipment authorized above 20 GHz, we believe that it is unlikely that this service would be used in the foreseeable future. Therefore, we believe that the proposed deletions will not affect small businesses.
        11. 135.7-137.8 kHz. The NPRM sought comment on whether this band should be allocated to the amateur service on a secondary basis. The only non-Federal use of this band is by Part 15 devices, such as Power Line Carrier (PLC) systems. If the band is allocated to the amateur service, amateur stations and PLC systems that operate PLC systems on electric transmission lines will most likely require coordination. We believe that any additional coordination requirements would have a de minimis impact on electric power companies.
        12. 156.4875-156.5625 MHz. The NPRM proposed to allocate the 156.4875-156.5125 and 156.5375-156.5625 MHz bands to the fixed service (FS) and land mobile service on a primary basis for non-Federal use, subject to not causing harmful interference to, nor claiming protection from, the maritime mobile VHF radiocommunication service. The NPRM also proposed to reallocate the 156.5125-156.5375 MHz band to the MMS (distress, urgency, safety and calling via digital selective calling). Because all existing MMS licensees would be protected from any interference caused by the proposals, the only possible impact would be to the 20 call signs authorizing land mobile service use. Because 18 of these call signs are held by the State of Arizona; one is held by the County of Los Angeles, California (CA); and one is held by the City of La Mesa, CA, which has a population of 57,065 (2010 census), none of these licensees are small governmental jurisdictions.
        13. AIS satellite reception. The NPRM proposed to permit satellites to receive Automatic Identification System (AIS) transmissions. Because this use will not be protected from harmful interference due to the operation of terrestrial services, no small entity will be negatively impacted. We believe that there may be a positive impact on Orbcomm Inc., which is a small business, if this allocation is adopted.
        14. 108-117.975 MHz. The NPRM proposed to allocate the band to the aeronautical mobile route service (AM(R)S) on a primary basis and to add new footnote US197A to the U.S. Table. US197A states that AM(R)S use of the 108-117.975 MHz band must not: (1) Cause harmful interference to the aeronautical radionavigation service (ARNS) (see Resolution 413); and (2) constrain the use of the 88-108 MHz band by FM radio stations operating in accordance with 47 CFR part 73. Because all incumbent licensees would be protected from interference caused by the new allocation, there can be no significant economic impact on small entities.
        15. 960-1164 MHz. The NPRM proposed to allocate the band to the AM(R)S on a primary basis and to add RR 5.327A to the U.S. Table. RR 5.327A states that AM(R)S use of the 960-1164 MHz band is limited to systems that operate in accordance with Resolution 417, which states that AM(R)S must not cause harmful interference to the ARNS. Because all incumbent licensees would be protected from interference caused by the new allocation, there can be no significant economic impact on small entities.
        16. 5091-5150 MHz. The NPRM proposed to allocate the band to the AMS on a primary basis and to add RR 5.444B to the U.S. Table. RR 5.444B, inter alia, restricts AMS use of the 5091-5150 MHz band to: (1) AM(R)S systems operating in accordance with international aeronautical standards, limited to surface applications at airports, and in accordance with Resolution 748, which states that this AM(R)S use may not cause harmful interference to the ARNS; (2) AMT transmissions from aircraft stations in accordance with Resolution 418, which requires that AMT operations use the spectrum sharing criteria set forth in Annex 1 of that Resolution; and (3) aeronautical security transmissions in accordance with Resolution 419, which states that administrations, in making assignments, shall ensure that AM(R)S requirements take precedence over AMS applications. Currently, non-Federal use of the 5091-5150 MHz band is limited to feeder uplinks for non-geostationary satellite orbit systems in the mobile-satellite service. No harmful interference is expected to the receivers on board the space stations.
        17. 1390-1395 and 1427-1435 MHz. The NPRM proposed to encourage licensees of stations authorized pursuant to parts 27 and 90 of the Commission's rules that transmit in the 1390-1395 MHz and 1427-1435 MHz band to comply with WRC-07's non-mandatory maximum values. The Commission has issued 64 call signs to 1 licensee (TerreStar 1.4 Holdings LLC) for the 1390-1395 MHz band and 13 call signs to 2 licensees (TerreStar 1.4 Holdings LLC and Mississippi State University) for the 1432-1435 MHz band. The Commission has issued 129 call signs to 47 licensees in the 1427-1432 MHz band. We believe that many of the licensees operating in these bands are small entities and that any costs and/or administrative burdens associated with the proposal will not be significant or otherwise unduly burden those small entities.
        18. 1435-1452 MHz. The NPRM proposed to encourage operators of aeronautical mobile telemetry (AMT) stations that transmit in the 1435-1452 MHz band to comply with WRC-07's non-mandatory unwanted emission level. The NPRM also request comment on whether AMT operators that can not meet this unwanted emission level should be required to seek their operational requirements in the 1452-1525 MHz band prior to operating in the 1435-1452 MHz band. As of April 24, 2012, the Commission has issued 23 calls to 13 licensees for stations in the Aeronautical and Fixed Service to operate in the 1435-1452 MHz band. We believe that at most 4 of these licensees are small businesses and that any costs and/or administrative burdens associated with the proposal will not unduly burden or have a significant economic impact on those limited number of small entities.
        19. 9000-9200 MHz. The NPRM proposed to raise the secondary Federal RLS from secondary to primary status. Because non-Federal RLS use is authorized on the condition that it not cause harmful interference to the secondary Federal RLS, the upgrade of the Federal RLS can have no significant economic impact on small entities.
        20. 9300-9500 MHz. The NPRM proposed to raise the secondary Federal RLS from secondary to primary status and to also allocate the 9300-9500 MHz band to the Earth exploration-satellite service (EESS) (active) and space research service (SRS) (active). Because non-Federal RLS use is authorized on the condition that it not cause harmful interference to the secondary Federal RLS, the upgrade of the Federal RLS can have no significant economic impact on small entities. We also believe that the proposed EESS (active) and SRS (active) allocations will have no significant economic impact on small entities.
        21. 9800-9900 MHz. The NPRM proposed to allocate the 9300-9500 MHz band to the EESS (active) and SRS (active) on a secondary basis. Because non-Federal RLS use is on a secondary basis to Federal RLS, we do believe that the proposed additional uses will have no significant economic impact on small entities.
        22. 10.6-10.68 GHz. The NPRM proposed to limit the power supplied to the antenna to −3 dBW (instead of −3 dBW/250 kHz) and to add advisory language for fixed point-to-point systems. The NPRM also solicits comment on whether more stringent operating requirements should apply to future fixed stations operating in this band. Because most licensed fixed stations already meet the proposed −3 dBW requirement, we do not believe that this proposal will affect a substantial number of small entities. We also do not believe that the advisory language and more stringent operating requirements would affect a substantial number of small entities.
        23. GOES Expansion. The NPRM proposed to allocate the 18-18.1 GHz band to the meteorological-satellite service (space-to-Earth) on a primary basis. The use of this allocation is expected to be limited to three locations. This band is allocated to the non-Federal FS on a primary basis. If adopted, this proposal would limit future FS licensing near the receiving earth stations. We do not believe that this proposal will affect a substantial number of small entities.
        24. 22.55-23.55 GHz. The NPRM proposed to adopt the WRC-07's mandatory unwanted emission limits from all new non-geostationary satellite orbit systems in the inter-satellite service transmitting in the 22.55-23.55 GHz band, and requested comment on how these limits should apply to the only incumbent licensee's (Iridium's) satellites on a going-forward basis. We do not believe that this proposal will affect a substantial number of small entities.
        25. 31-31.3 GHz. The NPRM proposed to urge licensees of fixed stations transmitting in the 31-31.3 GHz band to limit the maximum elevation angle of the antenna main beam to 20° and to employ automatic transmitter power control. The NPRM also requested comment on whether the Commission adopt WRC-07's mandatory unwanted emission limits for these stations. As of April 24, 2012, the Commission has issued 852 call signs to operate in the 31-31.3 GHz band: 109 licenses (777 call signs) in the Local Multipoint Distribution Service (LMDS); 19 licensees (23 call signs) in the Common Carrier Fixed Point-to-Point Microwave Service (CF) to 19 licensees; 9 licensees (9 call signs) in the Local Television Transmission Service (CT); 5 licensees (6 call signs) in the Microwave Public Safety Pool (MW); and 1 licensee (the State of Nevada, with 37 call signs) in the Microwave Industrial/Business Pool (MG). We believe that many of the LMDS licensees are small businesses, that at most 2 of the CF licensees are small businesses, that at most 3 of the CT licensees are small businesses, that at most 1 of the MW licensees are small governmental jurisdictions, and that the sole MG licensee is not a small entity. We do not believe that any costs and/or administrative burdens associated with the proposal will unduly burden or have a significant economic impact on those limited number of small entities.
        26. 36-37, 49.7-40.2, 50.4-50.9, and 51.4-52.6 GHz. The NPRM proposed to adopt WRC-07's: 1) Spectrum sharing criteria for stations in the fixed and mobile services transmitting in the 36-37 GHz band; 2) mandatory unwanted emission limits for earth stations in the fixed-satellite service transmitting in the 49.7-40.2 and 50.4-50.9 GHz bands; and 3) mandatory unwanted emission limits for fixed stations transmitting in the 51.4-52.6 GHz band. Because the Commission has not issued licenses for the 36-37 GHz, 49.7-40.2 GHz, 50.4-50.9 GHz, and 51.4-52.6 GHz bands, these proposals will have no significant economic impact on small entities.
        E. Steps Taken To Minimize Significant Economic Impact on Small Entities, and Significant Alternatives Considered
        27. The RFA requires an agency to describe any significant alternatives that it has considered in reaching its proposed approach, which may include the following four alternatives (among others): (1) The establishment of differing compliance or reporting requirements or timetables that take into account the resources available to small entities; (2) the clarification, consolidation, or simplification of compliance or reporting requirements under the rule for small entities; (3) the use of performance, rather than design, standards; and (4) an exemption from coverage of the rule, or any part thereof, for small entities.23

            23 See 5 U.S.C. 603(c).

        28. As we have explained in detail in section D, we do not expect that our proposals will have a significant economic impact on small entities. However, the NPRM requested comment on interference mitigation techniques, other than those adopted at WRC-07, which would lessen the long-term impact on all licensees in the 10.6-10.68 GHz, 22.55-23.55 GHz, and 31-31.3 GHz bands, while fully protecting passive sensor operations.
        F. Federal Rules That May Duplicate, Overlap, or Conflict With the Proposed Rule
        29. None.
        Ordering Clauses

        30. Pursuant to sections 1, 4, 301, 302(a), and 303 of the Communications Act of 1934, as amended, 47 U.S.C. 151, 154, 301, 302(a), and 303, and section 553(b)(B) of the Administrative Procedure Act, 5 U.S.C. 553(b)(B), this Notice of Proposed Rule Making is hereby adopted.

            § 87.303
            Frequencies.

            (d) Aeronautical mobile telemetry (AMT) operations are conducted in the 1435-1525 MHz, 2345-2395 MHz, and 5091-5150 MHz bands on a co-equal basis with U.S. Government stations.
            (1) Frequencies in the 1435-1525 MHz and 2360-2395 MHz bands are assigned in the mobile service primarily for aeronautical telemetry and associated telecommand operations for flight testing of aircraft and missiles, or their major components. The 2345-2360 MHz band is also available for these purposes on a secondary basis. Permissible uses of these bands include telemetry and associated telecommand operations associated with the launching and reentry into the Earth's atmosphere, as well as any incidental orbiting prior to reentry, of objects undergoing flight tests. In the 1435-1525 MHz band, the following frequencies are shared on a co-equal basis with flight telemetering mobile stations: 1444.5, 1453.5, 1501.5, 1515.5, and 1524.5 MHz. In the 2360-2395 MHz band, the following frequencies may be assigned for telemetry and associated telecommand operations of expendable and re-usable launch vehicles, whether or not such operations involve flight testing: 2364.5, 2370.5 and 2382.5 MHz. All other mobile telemetry uses of the 2360-2395 MHz band shall be on a non-interfering and unprotected basis to the above uses.
            (2) Frequencies in the 5091-5150 MHz band are assigned in the aeronautical mobile service on a primary basis for flight testing of aircraft. AMT use of these frequencies is restricted to aircraft stations transmitting to aeronautical stations (AMT ground stations) in the flight test areas listed in 47 CFR 2.106, footnote US111.
            (3) The authorized bandwidths for stations operating in the 1435-1525 MHz, 2345-2395 MHz, and 5091-5150 MHz bands are normally 1, 3 or 5 MHz. Applications for greater bandwidths will be considered in accordance with the provisions of § 87.135. Each assignment will be centered on a frequency between 1435.5 MHz and 1524.5 MHz, between 2345.5 MHz and 2394.5 MHz, or between 5091.5 MHz and 5149.5 MHz, with 1 MHz channel spacing.

            19. Section 87.305 is amended by revising paragraph (a)(1) to read as follows:

            § 87.305
            Frequency coordination.
            (a)(1) Each application for a new station license, renewal or modification of an existing license concerning flight test frequencies, except as provided in paragraph (b) of this section, must be accompanied by a statement from a frequency advisory committee. The committee must comment on the frequencies requested or the proposed changes in the authorized station and the probable interference to existing stations. The committee must consider all stations operating on the frequencies requested or assigned within 320 km (200 mi) of the proposed area of operation and all prior coordination and assignments on the proposed frequency(ies). The committee must also recommend frequencies resulting in the minimum interference. The Committee must coordinate in writing all requests for frequencies or proposed operating changes in the 1435-1525 MHz, 2345-2395 MHz, and 5091-5150 MHz bands with the responsible Government Area Frequency Coordinators listed in the NTIA “Manual of Regulations and Procedures for Federal Radio Frequency Management.” In addition, committee recommendations may include comments on other technical factors and may contain recommended restrictions which it believes should appear on the license.
