		The high-speed rail GSM-R communication system carries the data transmission of wireless automatic block signal on CTC-3 train, and it improves the reliability and safety of the system through the interlaced and covered network at base station. The TGZ-RG interlaced  repeater station is used for the weak field coverage of the GSM-R interlaced and covered system. It has high reliability by using the main, spare, three signals and module redundancy.
