Feasibility Analysis of 5091-5150 MHz Band Sharing by ANLE and MSS Feeder Links
Abstract
The Federal Aviation Administration plans to use the 5091-5150 megahertz band for the future Airport Network and Location Equipment (ANLE) system, which will provide an enhanced surveillance capability for airport surface environments. The same band has also been allocated on a co-primary basis to non-geostationary mobile-satellite-service (MSS) feeder uplinks, which must be protected against potential interference from ANLE transmissions. Our analysis demonstrates that if ANLE is based on the IEEE 802.11a or 802.16e standard, then compatibility with co-frequency MSS feeder links appears feasible by controlling the output power of ANLE transmitters, limiting their duty cycles, and distributing their frequency assignments among the three channels available in the band. Our results are contingent on the accuracy of our assumptions (which still need to be validated through field testing outside the scope of the present study) about the fading margins and path-loss exponents that apply to airport surface environments in the frequency band of interest.
