Final rule.


In this document, the Commission reallocated spectrum in the 76-81 GHz frequency band and the frequency bands above 95 GHz to conform the United States Table of Frequency Allocations with recent changes to the International Table of Frequency Allocations maintained by the International Telcommunication Union. In order to protect passive services in the 55.78-56.26 GHz band, the Commission also adopted a limit on the maximum power spectral density that can be delivered to a fixed service transmitter antenna.

Summary of the Report and Order

1. In the Report and Order, the Commission amended part 2 of the Commission's rules to realign spectrum in the 76-81 GHz frequency band and the frequency bands above 95 GHz to conform the United States Table with international allocation changes made at WRC-2000. The Commission also set a maximum power spectral density limit in the 55.78-56.26 GHz band to protect passive services.

2. Above 76 GHz. The Commission found that implementing the allocation changes from WRC-2000 in these bands was necessary to provide EESS and RAS operations with the flexibility to operate in spectrum suited to meet their needs. This action also promoted consistency between the U.S. Table and the International Table.

3. Regarding the 76-77 GHz band, the Commission recognized that vehicular radar operations in this band may be able to increase the level of safety on highways and benefit the public. The Commission agreed with commenters that sharing between RAS and SRS and vehicular radar operations was possible. Therefore, the 76-77 GHz band was allocated to the RAS on a primary basis and to the SRS on a secondary basis, as proposed.

4. In addition, the Commission found evidence of potential interference conflicts between the amateur-satellite service and vehicular radar systems. On this basis, it was anticipated that an amateur earth station could either receive interference to its operations or cause interference to a passing vehicular radar device. Therefore, the proposed secondary amateur-satellite allocation for the 76-77 GHz band as not implemented. However, the existing secondary amateur service allocation was retained, noting that the existing secondary amateur service allocation in this band was currently suspended and restricted until technical sharing criteria was developed to address potential sharing problems in this band. The Commission also found that not allowing amateur operations in the 76-77 GHz band was not a significant burden on this service because amateurs typically do not operate at these higher frequencies and they are permitted to operate in the adjacent 77-81 GHz band.

5. Regarding the 77-81 GHz segment, the Commission adopted domestically the RAS and SRS allocations as proposed in the Notice of Proposed Rule Making (NPRM), 68 FR 33043, June 3, 2003. Also, the Commission adopted the proposal set forth in the NPRM to realign spectrum in the bands above 95 GHz. This realignment would have little impact on the small number of systems that are currently implemented in these bands and no parties filed comments opposing these changes. It was found that potential interference conflicts between allocations or development of technical sharing criteria would be addressed, as appropriate, as future applications are developed or through the development of service rules.

6. Finally, the Commission deleted the seven United States footnotes that were adopted in the Table Clean-up Order in DA No. 02-1872, 67 FR 59601, September 23, 2002, for the purpose of maintaining the status quo for the U.S. Table, since the Report and Order adopted the realignment of WRC-2000, these footnotes no longer applied.

7. Maximum Power Density in the Band 55.78-56.26 GHz. The Commission found that the current state of the art output power for fixed systems operating in this spectrum was still several dB less than the power that Start Printed Page 13747would be permitted under the output power limit of −28.5 dB(W/MHz) that was recommended. It was noted that no licenses had been issued for operation in the fixed service in the 55.78-56.26 GHz band and that the Commission had only granted a few experimental licenses in this spectrum. Therefore, to protect EESS from unaccepted interference from fixed and mobile operations, footnote US379 was adopted, which limited the maximum power density delivered to fixed service transmitter antennas to −28.5 dB(W/MHz)

Final Regulatory Flexibility Analysis

8. As required by the Regulatory Flexibility Act (“RFA”),[1] the Commission incorporated an Initial Regulatory Flexibility Analysis (“IRFA”) in the Notice of Proposed Rulemaking and Order (“NPRM”), ET Docket No. 03-102.[2] The Commission sought written public comments on the proposals in the NPRM, including the IRFA. The Final Regulatory Flexibility Analysis (“FRFA”) in the Report and Order conforms to the RFA, as amended by the Contract With America Advancement Act of 1996 (“CWAAA”), Public Law 104-121, 110 Stat. 847 (1996).

9. 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 action taken.[3] The RFA generally defines the term “small entity” as having the same meaning as the terms “small business,” “small organization,” and “small governmental jurisdiction.”[4] In addition, the term “small business” has the same meaning as the term “small business concern” under the Small Business Act.[5] A small business concern is one that: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) meets any additional criteria established by the Small Business Administration (“SBA”).[6] A small organization is generally “any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.”[7] Nationwide, as of 1992, there were approximately 275,801 small organizations.[8] Finally, “small governmental jurisdiction” generally means “governments of cities, counties, towns, townships, villages, school districts, or special districts, with a population of less than 50,000.”[9]

10. The Commission will send a copy of this Final Regulatory Flexibility Analysis, along with this Report and Order, in a report to be sent to Congress pursuant to the Congressional Review Act, 5 U.S.C. 801(a)(1)(A). In addition, the Commission will send a copy of this Report and Order, including this FRFA, to the Chief Counsel for Advocacy of the Small Business Administration.
