[ET Docket No. 02-305; FCC 02-261]

World Radiocommunication Conferences Concerning Frequency Bands Above 28 MHz

AGENCY:

Federal Communications Commission.

ACTION:

Proposed rule.

SUMMARY:

In this document the Commission proposes to amend our rules in order to implement domestically various allocation decisions from several World Radiocommunication Conferences ("WRCs") concerning the frequency bands between 28 MHz and 36 GHz and to otherwise update our rules in this frequency range. The following proposals are the most significant to non-Federal Government operations: implementing generic mobile-satellite service ("MSS") allocations in the bands 1525-1559 MHz and 1626.5-1660.5 MHz ("L-band"); allocating the band 1164-1189 MHz to the radionavigation-satellite service ("RNSS"); and removing unused and limited fixed-satellite and broadcasting-satellite allocations from the band 2500-2690 MHz. In addition, at the request of the National Telecommunications and Information Administration ("NTIA"), the Commission has proposed various allocation changes for the space science services and the inter-satellite service ("ISS"), most of which involve spectrum primarily used by the Federal Government. These proposals would conform the Commission's rules to previous WRC agreements and are expected to provide significant benefits to the American public.

DATES:

Written comments are due February 10, 2003, and reply comments are due March 10, 2003.

Summary of Notice of Proposed Rule Making

1. The Notice of Proposed Rulemaking ( "NPRM" ) proposes to provide for generic MSS allocations across the bands 1525-1559 MHz and 1626.5-1660.5 MHz. Specifically, we proposed to expand the primary allocation in the bands 1545-1549.5 MHz, 1558.5-1559 MHz, 1646.5-1651 MHz, and 1660-1660.5 MHz from the aeronautical mobile-satellite (route) service ("AMS(R)S") to all services within the MSS while preserving the requirements of AMS(R)S. The effect of our proposal is that the bands 1545-1559 MHz and 1646.5-1660.5 MHz would be made available to all types of MSS communications on a primary basis, rather than segmented for specialized use. This action will permit more efficient use of this radio spectrum and will facilitate the expansion of MSS use globally. In addition, because the bands 1530-1544 MHz and 1626.5-1645.5 MHz are currently allocated to the maritime mobile-satellite service ("MMSS") and the MSS on a co-primary basis, we proposed to remove superfluous MMSS allocations. We are also requesting comment on whether the secondary allocation for aeronautical telemetry should be removed from the band 1525-1535 MHz.

2. The Commission proposes to allocate the band 1164-1189 MHz to the RNSS for space-to-Earth ("downlink") and space-to-space transmissions in order to accommodate a new civil global positioning system ("GPS") signal. This action would permit the addition of a new GPS signal and support the safety-of-life requirements demanded by civil aviation. We also proposed to allocate the bands 1215-1240 MHz and 1559-1610 MHz, which are currently limited to RNSS downlinks, for RNSS space-to-space transmissions as well. This action would allow use of spaceborne RNSS receivers for scientific and commercial applications.

3. The Commission proposes to downgrade the primary flight test and radiolocation allocations to secondary status in the band 2320-2345 MHz because the Satellite Digital Audio Radio Service ("Satellite DARS") has been brought into operation. We also propose to delete limited allocations for the fixed-satellite service ("FSS") and the broadcasting-satellite service ("BSS") from the band 2500-2690 MHz in order to remove allocations that are not compatible with two-way, point-to-multipoint fixed uses.

4. The Commission proposes to implement domestically various allocation decisions concerning the space science services and the ISS from several WRCs that have not previously been addressed by the Commission. These proposals deal with the following issues:

• Raising secondary allocations for the Earth exploration-satellite service ("EESS") and the space research service ("SRS") to primary status in 1035 megahertz of spectrum in eight frequency bands and to specify that these allocations are to used for active sensor operations ("EESS (active)" and "SRS (active)"): 1215-1240 MHz, 1240-1300 MHz, 5250-5255 MHz, 5255-5350 MHz, 8550-8650 MHz, 9500-9800 MHz, 13.4-13.75 GHz, and 17.2-17.3 GHz.

• Allocating 550 megahertz of additional spectrum to the EESS (active) and SRS (active) on a primary basis in the bands 13.25-13.4 GHz and 35.6-36 GHz. We would also change the primary footnote allocation for active spaceborne sensors in the band 35.5-35.6 GHz to a direct Table listing.

• Allocating 110 megahertz of additional spectrum to the EESS (active) on a primary basis in the band 5350-5460 MHz.

• Upgrading the allocation status of EESS uplinks and meteorological-satellite service ("METSAT") uplinks in the band 401-403 MHz from secondary to primary.

• Allocating the band 410-420 MHz to the SRS on a primary basis for space-to-space transmissions.

• Allocating the band 7750-7850 MHz for METSAT downlinks on a primary basis, limited to non-geostationary satellite systems.

• Allocating the band 8400-8450 MHz for SRS downlinks from deep space on a secondary basis.

• Allocating the band 25.25-27.5 GHz to the ISS on a primary basis.

• Raising the secondary EESS allocation to primary status in the band 25.5-27 GHz and changing its directional indicator from space-to-space to space-to-Earth.

5. In addition, we proposed to: (1) Remove the primary ISS allocation from the band 32-32.3 GHz; (2) remove the secondary allocation for the aeronautical mobile-satellite (route) service ("AMS(R)S") from the band 136-137 MHz; (3) more than double the size of the geographic area in New Mexico and Texas where amateur stations in the band 420-450 MHz would be limited in power and where spread spectrum radiolocation systems in the sub-band 420-435 MHz should not expect to be accommodated; (4) reflect NTIA's recent action, which specified that Federal Government wind profiler radar systems ("wind profilers") will operate in the sub-band 448-450 MHz; (5) permit U.S. flagged ships to use more spectrum-efficient equipment for on-board mobile radiotelephony communications in areas outside the territorial waters of the United States; (6) remove unused allocations for the International Fixed Public Radiocommunication Services from the bands 2.1-2.2 GHz and 10.7-11.7 GHz; and (7) allocate the band 14-14.5 GHz to the mobile-satellite (Earth-to-space) except aeronautical mobile-satellite service on a secondary basis. The Commission also proposes to make numerous ministerial amendments to part 2 of our rules.

Initial Regulatory Flexibility Certification

6. The Regulatory Flexibility Act of 1980, as amended ("RFA"), 1 requires that an initial regulatory analysis be prepared for notice-and-comment rule making proceedings, unless the agency certifies that the "the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities. 2 The RFA generally defines the term "small entity" as having the same meaning as the terms "small business," "small organization," and "small governmental jurisdiction." 3 In addition, the term "small business" has the same meaning as the term "small business concern" under the Small Business Act. 4 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"). 5

Footnotes:

¹ See 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. 104-121, Title II, 110 Stat. 857 (1996).

² 5 U.S.C. 605(b).

³ 5 U.S.C. 601(6).

⁴ 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 ."

⁵ 15 U.S.C. 632.

7. The Notice of Proposed Rule Making ("NPRM") proposed to amend parts 2, 25, and 87 of the Commission's rules in order to implement domestically various allocation decisions from several World Radiocommunication Conferences concerning the frequency bands between 28 MHz and 36 GHz and to otherwise update our rules in this frequency range. These allocation proposals mainly affect Federal agencies.⁶Those proposals that are most significant to non-Federal Government operations are: (1) Implementing generic L-band MSS allocations; (2) allocating the band 1164-1189 MHz to the RNSS; and (3) removing unused and limited FSS and BSS allocations from the band 2500-2690 MHz. Concerning L-band MSS, currently there is only one U.S. licensee. Concerning the RNSS allocation, only one or at most a few large companies are expected to be able to launch and maintain RNSS systems, which are expensive. The last proposal merely deletes unused allocations, with no direct effect on licensees or regulatees.

Footnotes:

⁶ See paras. 5-6, supra.

8. We have determined that the rules proposed in the NPRM will not, if promulgated, have a significant economic impact on a substantial number of small entities. Accordingly, we hereby certify that this NPRM will not have a significant economic impact on a substantial number of small entities. The Commission's Consumer and Governmental Affairs Bureau, Reference Information Center, will send a copy of this NPRM, including this certification, to the Chief Counsel for Advocacy of the Small Business Administration.⁷
