Interference analysis status and plans for aeronautical mobile airport communications system (AeroMACS)

Need to establish practical limits on AeroMACS transmissions from airports so that the threshold of interference into MSS and other C-band systems is not exceeded. Enable the development of standards under RTCA SC-223. Analyses have been started with Visualyse, a powerful and flexible interference analysis software tool. Visualyse results with omni-directional antenna transmitters agree very well with results from MITRE-CAASD. Near term plans to improve model realism with multi-sector antennas and subscriber stations.
