Abstract :
The modernization of air/ground (A/G) communications in the very high frequency (VHF) band for Air Traffic Services (ATSs) and Aeronautical Operational Control (AOC) applications is becoming increasingly important as the competition for the existing frequency spectrum intensifies. The Federal Aviation Administration (FAA) is currently exploring various modernization alternatives ranging from channel splitting to an integrated digital voice and data system utilizing a single avionics unit that supports ATS and AOC. A mandatory aspect of ATS applications is the preservation of real-time response capabilities for critical services. This paper addresses technical tradeoffs in the areas of spectrum efficiency, throughput, and operational performance of viable system alternatives that could satisfy present and future needs
