Spectrum Protection refers to the management of the radio-frequency spectrum in order to protect particular interests. The spectrum includes not only communications and datalink applications, but also navigation and other uses. Aviation is just one of the many users of the spectrum. The useable spectrum expands with technological advances however there are often competing demands for particular frequency bands. States decide on spectrum use at World Radio-communication Conferences (WRC) organised by the International Telecommunications Union (ITU).
IFATCA Policy is:The radio-frequency spectrum shall be managed in a manner that at all times ensures the safety of current aviation activity and allows for future safety-of-flight applications. Existing spectrum allocations for exclusive aviation use shall not allow other uses until it is thoroughly proven that aviation safety will not be compromised by the shared use of the spectrum allocation. Prior to aviation use of shared spectrum allocations, it shall be thoroughly proven that safety-critical aviation requirements are not compromised. Adequate protection against harmful interference to aviation spectrum use shall be ensured. IFATCA encourages the development of technology which utilizes the frequency spectrum more efficiently. |
