GSM-R Signal Interference & the GHAN 1.5 Filter

 

GSM-R communication in trains is susceptible to signal interference from cellular network towers placed in the vicinity of the tracks. However, the core safety proposition behind GSM-R warrants ultra-reliable communication at all times. With Tongyu's Ghan 1.5 Filter a functional, rapid and efficient solution is now available.

Key Filter Benefits

The most efficient solution for expanding the working life of currently installed cab radios, while taking ETSI requirements into consideration!
