High-speed maglev trains will be very competitive ground transportation tools in the future because of their high speed and convenience. However, high-speed maglev train-ground communication faces the Doppler effect caused by high-speed motion, frequent handovers, high real-time transmission requirements, and the requirements of carrying multiple services. In this paper, the adaptability of common civil communication and railway subway communication technologies such as Wireless Local Area Network(WLAN), 38 GHz millimeter wave and Long Term Evolution-Metro(LTE-M)/ 5G in high-speed maglev system is studied, and the analysis on the application of these communication technologies in the train-ground communication environment of high-speed maglev system is carried out. The direction and technical route of how to improve and apply these communication technologies are put forward.
