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.

  • Executive Summary of the ICAO Position for ITU WRC-15 Radio
    Executive Summary of the ICAO Position for ITU WRC-15 Radio frequency spectrum is a scarce natural resource with finite capacity for which demand is constantly increasing. The requirements of civil aviation as well as other spectrum users continue to grow at a fast pace, thus creating an ever-increasing pressure to an already stretched resource. International competition between radio services obliges all spectrum users, aeronautical and non- aeronautical alike, to continually defend and justify retention of existing or addition of new frequency bands. The ICAO Position aims at protecting aeronautical frequency spectrum for all radiocommunication and radionavigation systems used for ground facilities and on board aircraft. The ICAO Position addresses all radioregulatory aspects on aeronautical matters on the agenda for the WRC-15. The items of main concern to aviation include the following: identification of additional frequency bands for the International Mobile Telecommunications (IMT). Under this agenda item, the telecommunications industry is seeking up to 1200 MHz of additional spectrum in the 300 MHz to 6 GHz range for mobile and broadband applications. It is expected that a number of aeronautical frequency bands will come under pressure for potential repurposing, especially some of the Primary Surveillance Radar (PSR) bands. Existing frequency allocations which are vital for the operation of aeronautical very small aperture terminal (VSAT) ground-ground communication networks, especially in tropical regions, are also expected to come under pressure. Due to decisions made by a previous WRC, this has already become a problematic issue in Africa. WRC-15 agenda items 1.1 and 9.1.5 refer; potential radioregulatory means to facilitate the use of non-safety satellite service frequency bands for a very safety-critical application, the command and control link for remotely piloted aircraft systems (RPAS) in non-segregated airspace.

  • International Air Transport Association Position for the World Radiocommunication Conference (WRC - 12)
    International Air Transport Association Position for the World Radiocommunication Conference (WRC - 12) September 2009 Objectives of IATA Position The IATA Position) for the World Radiocommunication Conference (WRC 12) seeks to guarantee appropriate, secure radio spectrum to support current and planned CNS technologies and systems essential to meeting future growth in a safe and efficient manner. Due to the safety and global harmonization of airline operations, allocations for such radio spectrum are made at WRC’s, the outcomes of which have international treaty status. IATA believes such international coordination is essential and opposes the application of new, more market driven, regulatory measures to the spectrum aviation uses. The broad objectives of the IATA position are: • to maintain protection for the spectrum used for aeronautical radiocommunication and radionavigation systems required for current and future safety-of-life applications; • to ensure that spectrum is available for new technologies; • to ensure that the application of new regulatory measures does not impact on global operations or result in social or economic penalty to aviation without providing benefit. IATA has 226 member airlines carrying 93% of world’s international scheduled traffic (Available Seat Kilometres). In 2008, IATA’s members carried 1.6 billion passengers (scheduled) of which 708 million were international and 42.3 million tones of freight of which 28 million tonnes were international Introduction Aviation uses globally harmonised spectrum allocations for communications, navigation and surveillance in order to provide a safe and efficient global transport system. Hence the spectrum used by aviation must be free from harmful interference to guarantee the integrity of its systems.

  • WMO Position Onwrc-15 Agenda (March 2014)
    WORLD WEATHER WATCH COMMISSION FOR BASIC SYSTEMS WMO Position onWRC-15 Agenda (March 2014) 1 Introduction Timely warning of impending natural and environmental disasters, accurate climate prediction and detailed understanding of the status of global water resources: these are all critically important everyday issues for the global community. National Meteorological and Hydrological Services (NMHS) around the world are responsible for providing this information, which is required for the protection of the environment, economic development (transport, energy, agriculture,..) and the safety of life and property. Radio-frequencies represent scarce and key resources used by National Meteorological and Hydrological Services to measure and collect the observation data upon which analyses and predictions, including warnings, are based or processed, and to disseminate this information to governments, policy makers, disaster management organisations, commercial interests and the general public. Nowadays radio-based remote sensors (active and passive) are the main tools for environment and climate monitoring, disaster prediction, detection and mitigating negative effects of disasters. These sensors obtain environmental data by measuring level and parameters of natural and artificial radio waves that inherently contain information about the environment with which they have been in contact. Terrestrial and space-born remote sensing applications form the backbone of the WMO Integrated Global Observing System. WMO information systems also make extensive use of radiocommunication systems and radio- frequency spectrum, and although they are also using commercially provided services such as communication satellites, meteorological related radiocommunication systems are an essential and indispensable component of WMO’s critical data collection and distribution systems (e.g. Earth-to- space and space-to-Earth transmissions).

  • Canadian Table of Frequency Allocations (2018 Edition)
    Published April 2018 Spectrum Management and Telecommunications Canadian Table of Frequency Allocations (2018 Edition) Aussi disponible en français Innovation, Science and Economic Development Canada 2018 The revised Canadian Table of Frequency Allocations is available electronically on ISED’s Spectrum Management and Telecommunications website. i Foreword The Canadian Table of Frequency Allocations (Canadian Table) assigns the electromagnetic spectrum and establishes the frequency allocations available for radio services in Canada. The Canadian Table is based on the provisions of the Final Acts resulting from the various World Radiocommunication Conferences (WRC), including the 2015 WRC, convened by the International Telecommunication Union (ITU). The Canadian Table and the associated general information will, from time to time, need to be revised. Such revisions occur when changes to the ITU Table of Frequency Allocations (ITU Table) are made as a result of World Radiocommunication Conferences or particular Canadian radio service requirements. The Canadian Table reflects international changes while taking into account Canadian requirements to ensure that government, commercial and private users have full flexibility to develop new radio applications and systems. The Canadian Table is intended to respond to Canadian domestic spectrum requirements, and consequently reflects Innovation, Science and Economic Development Canada’s (ISED) spectrum allocation and utilization policies developed through public consultation. It should be noted, therefore, that the Canadian Table differs, where necessary, from the ITU Table. Canadian radio systems and spectrum utilization policies set the necessary elements for the use of frequency bands and/or radio services. Spectrum policies have traditionally designated the use of a radio service to certain applications in a particular frequency band, or bands.

  • Introduction to International Radio Regulations
    Introduction to International Radio Regulations Ryszard Struzak∗ Information and Communication Technologies Consultant Lectures given at the School on Radio Use for Information And Communication Technology Trieste, 2-22 February 2003 LNS0316001 ∗ [email protected] 2 R. Struzak Abstract These notes introduce the ITU Radio Regulations and related UN and WTO agreements that specify how terrestrial and satellite radio should be used in all countries over the planet. Access to the existing information infrastructure, and to that of the future Information Society, depends critically on these regulations. The paper also discusses few problems related to the use of the radio frequencies and satellite orbits. The notes are extracted from a book under preparation, in which these issues are discussed in more detail. Introduction to International Radio Regulations 3 Contents 1. Background 5 2.

The converging computer and communications technologies add “intelligence” to old applications and generate new ones. The enormous impact of radio on the society continues to increase although we still do not fully understand all consequences of that process. There are numerous areas in which the radio frequency spectrum is vital. National defence, public safety, weather forecasts, disaster warning, air-traffic control, and air navigation are a few examples only.
