Performance Evaluation of AeroMACS using existing WiMAX System in Japanese High-Speed Trains

AeroMACS (Aeronautical Mobile Airport Communication System) is being developed in order to provide new broadband wireless communications on the airport surface. In this paper, results of experiments using existing WiMAX (Worldwide Interoperability for Microwave Access) systems and Japanese high-speed trains (Shinkansen) are reported. We consider the capability of the AeroMACS system in high-speed scenarios, e.g. take-offs and landings. The relationship among frequency offset, moving speed and throughput are analyzed. We found that transmission of movies during take-off and landing is possible if CINR on the runway is higher than about 24dB and the base station is set at an appropriate position to reduce the influence of the Doppler shift.
