Abstract: Wireless communication technology has experienced analog communication, digital communication and now widely used broadband communication, In view of the evolution of private network communication from narrowband to broadband, it is introduced to the functions, comparison and interconnection of the metro radio dispatching communication system. The development status of rail transit in 5G era and the trend of trunking communication mode are discussed preliminarily.

Key words: radio dispatching communication system; TETRA; LTE; 5G
