Mobile-Satellite Service above 1 GHz

AGENCY: Federal Communications Commission.

ACTION: Final rule.

SUMMARY: This document makes new spectrum available on a co-primary basis to the fixed-satellite service (``FSS''). These FSS allocations will provide necessary feeder link spectrum for a number of commercial Non-Geostationary Satellite Orbit Mobile-Satellite Service (``NGSO MSS'') systems. Specifically, we allocate the bands 5091-5250 MHz and 15.43-15.63 GHz for Earth-to-space transmissions (``uplinks'') and the band 6700-7025 MHz for space-to-Earth transmissions (``downlinks''). In addition, we grandfather two satellite systems and their associated earth stations at three sites in the downlink band 7025-7075 MHz. In accordance with international regulations, the use of these FSS allocations is limited to feeder links that will be used in conjunction with the service links of NGSO MSS systems. These actions are intended to facilitate the introduction of innovative global radiocommunication services, consistent with international allocations for these frequency bands, and will provide incumbent operations with adequate protection from harmful interference.

DATES: Effective May 10, 2002.

Summary of Report and Order

1. We are allocating 325 megahertz of spectrum on a co-primary basis for NGSO MSS feeder downlinks, with an additional 50 megahertz limited to two grandfathered satellite systems and their associated earth stations at three sites. The grandfathered sites are listed in footnote NG173. In addition, we are allocating 359 megahertz of spectrum on a co-primary basis for NGSO MSS feeder uplinks. A portion of this primary uplink allocation (59 megahertz) is temporary in nature. The need for this amount of feeder link spectrum is based on the amount of NGSO MSS service link spectrum that is available, the frequency reuse of the service link spectrum, the need for NGSO MSS feeder link earth stations (``gateways'') to service multiple satellites, and the need to coordinate with incumbent terrestrial operations. These allocations will be used exclusively by commercial NGSO MSS systems for the connection between their satellites and gateways. We have previously allocated spectrum for 2 GHz MSS and Big LEO service links. (Big LEO service links are at 1610-1626.5 MHz and 2483.5-2500 MHz and 2 GHz MSS service links are at 1990-2025 MHz and 2165-2200 MHz.) The adoption of these FSS allocations will allow us to remove conditions placed on Big LEO and 2 GHz MSS licensees' feeder links, which we have previously licensed by waiver.

2. The band 5000-5250 MHz is currently allocated to the aeronautical radionavigation service (``ARNS'') and to several aeronautical support services on a primary basis. ARNS is a radionavigation service intended for the safe operation of aircraft. The microwave landing system (``MLS''), an

   [[Page 17289]]

   ARNS system, is an all-weather precision approach and landing system that currently operates in the band 5030-5091 MHz. Prior to this action, MLS requirements had unencumbered use of the band 5000-5250 MHz over any other use, including other ARNS systems and other primary services.

3. To provide spectrum for NGSO MSS feeder uplinks, we are removing MLS's right of precedence over all other uses in the band 5150-5250 MHz, but are maintaining that right in the band 5000-5150 MHz. Consistent with international allocations, no new NGSO MSS feeder link assignments will be made in the band 5091-5150 MHz after January 1, 2008; and two years later, FSS use of this band becomes secondary to ARNS. In addition, MLS requirements that can not be met in the band 5000-5091 MHz take precedence over all other uses of the band 5091-5150 MHz. These requirements are codified at 47 CFR 2.106, footnote S5.444A, and are being adopted domestically in this Order. Together, these actions will accommodate first generation NGSO MSS feeder link requirements, while providing existing MLS stations, which operate in the band 5030-5091 MHz, and gateways, which will operate in the band 5091-5250 MHz, with non-overlapping spectrum. We are also removing unused and unneeded aeronautical support allocations. Specifically, we are removing the aeronautical mobile-satellite (R) service (``AMS(R)S'') from the bands 5150-5250 MHz and 15.4-15.7 GHz, the inter-satellite service (``ISS'') from the bands 5000-5250 MHz and 15.4-15.7 GHz, and the FSS to the extent that it is limited to aeronautical support functions from the bands 5000-5250 MHz and 15.4- 15.7 GHz.

4. Incumbent terrestrial users of the band 6700-7075 MHz raise several concerns with regard to sharing this band with NGSO MSS feeder downlinks. To resolve these concerns, we adopt the proposed power flux- density (``pfd'') limits and establish coordination procedures in the band 6700-6875 MHz using existing parts 25 and 101 rules. The pfd limits have been added to Sec. 25.208. If an NGSO MSS satellite transmitting in the band 6700-6875 MHz causes harmful interference to previously licensed co-frequency Public Safety facilities, then that satellite licensee is obligated to remedy the interference complaint. This requirement has been added as Sec. 25.147.

5. We will address coordination requirements in the band 6875-7025 MHz in a future proceeding, but as an interim measure specify that coordination in this band will be on an individual basis using existing parts 25 and 101 rules. The focus of that proceeding will be the issue of ``growth zones,'' the protection of incumbent mobile operations in their normal operating area; and the protection of receive earth stations from later-licensed mobile stations. In addition, we observe that terrestrial fixed users' concerns about effective and equitable use of spectrum in bands shared by the FSS and the fixed service are being considering in IB Docket No. 00-203.

6. In order to permit (mobile) television pickup (``TVPU'') stations to continue to operate freely on two channels in essentially all of the country (in addition to two other channels, which will not share spectrum with gateways), we are limiting the use of the band 7025-7075 MHz to three gateways, two of which are operational and the other of which is undergoing testing. In addition, we recommend that, in the band 6875-7125 MHz, airborne TVPU stations use the channels 7075-7100 MHz and 7100-7125 MHz wherever possible. We find that these actions balance competing demands for spectrum and will mitigate interference between satellite and terrestrial services.

7. We explicitly require that applications for commercial earth stations in the bands 5091-5250 MHz and 15.43-15.63 GHz be coordinated with Federal agencies. In order to better protect MLS operations in the band 5000-5091 MHz, we recommend that non-Government tracking and telecommand operations be conducted in the band 5150-5250 MHz. These requirements are in footnotes US344 and US359 and in Secs. 25.202 and 87.173. The following table summarizes the existing domestic allocations versus the allocations we are adopting in this Order.

   Final Regulatory Flexibility Certification

8. The Regulatory Flexibility Act (``RFA'')\1\ requires that a regulatory flexibility analysis be prepared for notice and comment rulemaking proceedings, unless the agency certifies that ``the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities.'' The RFA generally defines ``small entity'' as having the same meaning as the terms ``small business,'' ``small organization,'' and ``small governmental jurisdiction.'' In addition, the term ``small business'' has the same meaning as the term ``small business concern'' under the Small Business Act. 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).

   \1\ The RFA, 5 U.S.C. 601 et. seq., has been amended by the Contract with American Advancement Act of 1996, Public Law 104-121, 110 Stat. 847 (1996) (``CWAAA''). Title II of the CWAAA is the Small Business Regulatory Enforcement Fairness Act of 1996 (``SBREFA'').

9. This Report and Order allocates the bands 5091-5250 MHz and 15.43-15.63 GHz for FSS uplinks on a primary basis, allocates the band 6700-7025 MHz on a primary basis for FSS downlinks, and limits the use of these FSS allocations to feeder links that would be used in conjunction with the service links of NGSO MSS systems. In addition, two satellite systems and three sites are grandfathered in the downlink band 7025-7075 MHz. We take this action on our own initiative in order to adopt domestically the NGSO MSS feeder link allocations that have been adopted internationally. These allocations will accommodate the growing demand for NGSO MSS services and will provide satellite operators with increased flexibility in the design of their systems.

10. The Commission has not developed a definition of small entities specifically applicable to the satellite services licensees here at issue. Therefore, the applicable definition of small entity in the satellite services industry is the definition under the Small Business Administration (``SBA'') rules applicable to Communications Services ``Not Elsewhere Classified.''\2\ This definition provides that a small entity is expressed as one with $11.0 million or less in annual receipts. According to Census Bureau data, there are 848 firms that fall under the category of Communications Services, Not Elsewhere Classified. Of those, approximately 775 reported annual receipts of $11 million or less and qualify as small entities.\3\ The Census Bureau category is very broad and commercial satellite services constitute only a subset of its total.

11. None of the NGSO MSS licensees is a small business because each has revenues in excess of $11 million annually or has a parent company or investors that have revenues in excess of $11 million annually.

12. The Commission did not receive any comments on its the initial regulatory flexibility certification. Nonetheless, we take this opportunity to explain a de minimus burden with regards to terrestrial users in the band 6700-7025 MHz. In the Notice of Proposed Rule Making, the Commission proposed to allocate the band 6700-7075 MHz to the FSS for satellite transmissions down to earth stations on a primary shared basis with incumbent users. Because such co-primary use implies coordination, the comments of the terrestrial users focused on limiting the impact of the allocation by placing restrictions on earth station use of the band, that is, the terrestrial parties requested that the normal coordination process not apply to this band. In the Report and Order, the Commission requires the use of the normal coordination process in the band 6700-6875 MHz, which is used by fixed point-to- point microwave licensees. If gateway applications are filedprior to the completion of an upcoming rule making that will deal with final coordination rules in the band 6875-7025 MHz, then case-by-case coordination will be required of the gateway applicants. Our action to limit the number of sites for earth stations in the band 7025-7075 MHz to three will also reduce future coordination costs. The Commission finds that, because of the limited number of receive earth stations to be deployed and their viable locations (that is, in rural areas), there will be minimal impact on potential

    [[Page 17291]]

    coordination costs. We therefore certify that this Report and Order will not have a significant economic impact on a substantial number of small entities.

13. The Commission will send a copy of the Report and Order, including a copy of this final certification, in a report to Congress pursuant to the Congressional Review Act, 5 U.S.C. 801(a)(1)(A). In addition, the Report and Order and this certification will be sent to the Chief Counsel for Advocacy of the Small Business Administration, 5 U.S.C. 605(b).
