Why don't voice radio communications use FM?
Larry Dighera wrote:
Because it is unlikely the FCC will agree to allocate additional frequency spectrum for the proposed new communications system. The frequency allocation would need to be changed or added to on an international scope, so I believe the operative organizations would be the ITU and the ICAO or IATA - the FCC would simply enforce the change within the U.S. Like you, I would have thought new allocations or changed allocations would be hard, but changes are made every four years and in the GHz range they seem to been more readily done; e.g.: http://www.boeing.com/connexion/news...r_030707j.html |
