ABSTRACT
The Federal Aviation Administration (FAA) is considering the use of the 5091-5150 MHz band
for a future Airport Network and Location Equipment (ANLE) system. ANLE is visualized as a
high-integrity, safety-rated wireless local area network (WLAN) for the airport surface, with
terminals on the ground and on taxiing aircraft. In this analysis, The MITRE Corporation's
Center for Advanced Aviation System Development (CAASD) has identified potential classes of
sensors and other fixed and mobile applications that may participate in such networks. We have
derived approximate upper bounds on the aggregate data rates and total bandwidth requirements
of those potential applications. These upper bounds will provide a basis for estimating the total
amount of radio spectrum that may be needed by an operational ANLE system.
