IntroductionIntroduction
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).

ITUITU
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’s roleICAO’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
ICAO Radio Spectrum Seminar MID Office, Cairo, 4 – 6 June 2006 9
Main goals for WRC-07Main 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
