  • 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.

  • 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.
