Abstract: According to the operation characteristics of high speed maglev of 600 km/h long main line and its demand for radio communication, an engineering scheme of "38 GHz millimeter wave plus DMR" radio communication system is proposed. 38 GHz millimeter wave is used to carry real-time safety data such as maglev train positioning data; DMR is used to realize voice communication for dispatching, passenger transport, operation and maintenance. According to the system business requirements, 38 GHz millimeter wave can also carry high-bandwidth services such as on-board PIS and on-board video. This scheme not only meets the real-time and reliability requirements of traction power supply and operation control system business, but also meets the voice communication requirements of dispatching and passenger transport required by the operation of long main lines while saving investment as much as possible and considering industrial support.

Key words: high speed maglev for long main lines, radio communication, 38 GHz millimeter wave, Digital Mobile Radio (DMR)
