INTRODUCTION 1. By this action, we realign allocations in the 50.2-50.4 GHz and 51.4-71 GHz frequency bands. This action continues our efforts to facilitate the commercialization of the "millimeter wave" spectrum. Until recently, commercial use of this spectrum was not economically viable. However, recent technological advances make this spectrum increasingly usable for commercial services and products. Therefore, we have reexamined potential uses of this spectrum and how best it can be allocated to further the public interest. The realignment of allocations that we adopt today will meet current demands for spectrum in this frequency range and is consistent with the international allocation changes the United States sought and obtained at the 1997 World Radiocommunication Conference ("WRC-97"). II. EXECUTIVE SUMMARY 2. We are providing a net increase of 2.27 gigahertz of spectrum allocated on a primary basis to the fixed and mobile services.1 This spectrum will be shared by Federal agencies and non-Federal Government licensees. Specifically, we allocate the 51.4-52.6 GHz and 58.2-59 GHz bands to the Federal and non-Federal Government fixed and mobile services, allocate the 64-66 GHz band to the Federal and non-Federal Government fixed and mobile except aeronautical mobile services, and delete the Federal and non-Federal Government fixed and mobile services from the 50.2-50.4 GHz and 54.25-55.78 GHz bands. We anticipate that much of this spectrum will be used by mobile service licensees to connect their base stations together and to connect their systems to other systems ("backbone infrastructure for mobile services"). We are also making the 57-59 GHz band available for use by Part 15 unlicensed devices.2 This 2 gigahertz of spectrum and the existing Part 15 unlicensed band at 59-64 GHz will operate under the same technical rules. We anticipate that this additional unlicensed spectrum (used either separately or in conjunction with the 59-64 GHz band) will be useful for very high speed and/or high bandwidth communications over short distances and for networking backbone purposes in congested areas. 3. We are also providing separate inter-satellite service ("ISS")3 allocations for Federal agencies and for non-Federal Government ("commercial") licensees. Specifically, we allocate the 65-71 GHz band to the non-Federal Government ISS and delete the non-Federal Government ISS allocation from the 56.9-57 GHz and 59-64 GHz bands. We also allocate the 64-65 GHz band to the Federal Government ISS. The net result of the ISS allocations and deletions is an increase of 0.9 GHz for commercial ISS and 1 GHz for Federal ISS. The remaining ISS allocations in this frequency range (54.25-56.9 GHz and 57-58.2 GHz) will be available for both Federal and commercial use. These ISS allocations will provide satellite licensees with the spectrum they need to interconnect satellites within their respective networks. The use of inter-satellite links are expected to make satellite networks more efficient, resulting in the provision of more enhanced services like video telephony, medical and technical tele-imaging, high speed data networks and "bandwidth on demand" to consumers. In addition, the use of inter-satellite links will enable satellite licensees to provide more efficient interconnections between their service areas.4 1 The fixed service is a radiocommunication service between specified fixed points. The mobile service is a radiocommunication service between mobile and land stations, or between mobile stations. 47 C.F.R. § 2.1(c). More specifically, 2 of the 2.27 gigahertz is not allocated to the aeronautical mobile service, i.e., the 64-66 GHz band is allocated to the mobile except aeronautical mobile service in order to protect inter-satellite links. 2 47 C.F.R. Part 15 - Radio Frequency Devices. 3 ISS is a radiocommunication service providing links between satellites. 47 C.F.R. § 2.1(c). 4 See joint Comments of Loral Space and Communications Ltd. and Globalstar, L.P. at 3. 2 Federal Communications Commission FCC 00-442 4. To provide spectrum for the above services, we are reducing the net amount of spectrum allocated to the Earth exploration-satellite (passive) and space research (passive) services by 1.9 gigahertz and are reducing the amount of spectrum allocated to the radio astronomy service by 4.65 gigahertz. According to NTIA, the deleted space research (passive) and radio astronomy allocations are unused and unneeded and the deleted Earth exploration-satellite (passive) allocations are unneeded. In sum, the realignment provides a significant increase in spectrum for fixed, mobile, and inter-satellite services and unlicensed devices, while improving the operation of passive sensors in the Earth exploration-satellite service ("EESS").5 The Table, below, summarizes the existing allocations versus the allocations as realigned in this Order.6 5 Passive sensor operations in the 54.25-59.3 GHz band are protected by generally limiting the use of the ISS allocations in this band to transmissions between satellites in geostationary orbit and by limiting the energy that can reach the passive sensor satellites, which operate much closer to the Earth's surface. 6 See 47 C.F.R. § 2.106 - Table of Frequency Allocations for the complete listing of existing allocations and footnotes to the Table. 3 Federal Communications Commission FCC 00-442 Existing vs Realigned Allocations (Federal and non-Federal Government allocations are identical, unless otherwise specified) Band Existing Allocations Realigned Allocations Summary of Major Changes (GHz) 50.2-50.4 EESS (passive) EESS (passive) Reduction of 0.2 GHz for fixed SPACE RESEARCH (passive) SPACE RESEARCH and mobile services.
