Introduction
 Aircraft operation would neither be safe nor be
capable of meeting the global demand for rapid and
cost-effective transport without aeronautical radio
services.
 Radio spectrum is a scarce natural resource with
finite capacity limits and constantly increasing
demands.
 Radio frequency spectrum congestion imposes the
need for an efficient and effective spectrum and
frequency management system.

Spectrum and Frequency
Management
 Spectrum management is the combination of
administrative and technical procedures necessary to
ensure the interference-free and efficient operation of
radio services (e.g. Radionavigation).
 Frequency management deals with the assignment of
frequencies to transmitting and/or receiving stations
(e.g. airborne radio station).

ITU
 The International Telecommunication Union (ITU) is
the specialized agency of the United Nations for
telecommunications matters where international
agreements are made on the use of the radio
frequency spectrum
 ITU Radio Regulations provide a basis for the
regulation of radio frequency spectrum between 9
kHz and 275 GHz

ICAO
 Was created in 1944 to promote the safe and orderly
development of civil aviation in the world
 Specialized agency of the United Nations, sets
international Standards and Regulations necessary
for the safety, security, efficiency and regularity of air
transport…

ICAO’s role
 Analyze the agenda of ITU WRC’s (World
Radiocommunication Conferences)
 Develop an ICAO position
 Work with ITU and Regional Telecommunications
Organizations (APT, CEPT, CITEL…)
 Submit the approved position to States and ITU
 Participate in WRC’s

Main goals for WRC-07
 Protect airborne weather radar and primary radar
systems for short-range applications including
precision approach radar and airport surface
detection equipment (ASDE)
 Protect high frequency (HF) bands used for
aeronautical communications and to review
regulatory and operational provisions for maritime
mobile service identities (MMSIs) on search and
rescue aircraft
 Introduce additional global spectrum allocations to
accommodate new applications to satisfy future air
traffic management (ATM) and potential aviation
security requirements

States
 Assist in the development of the ICAO position
 Participate with aviation experts in the work of ITU
and Regional Telecommunications Organizations
 Send aviation experts to WRC’s (A32-13)
 Support ICAO position (Assembly Resolution A32-13)
 WRC-2007 – Geneva Switzerland, October 2007
