What GSM-R?

GSM-R stands for Global System for Mobile Communications – Railways. It is an international wireless communications for railways that is used for traffic control. GSM-R ensures smooth movement of trains. it delivers digital and secure communications between the train and the railway regulation control centres.

How many exclusive channels are offered by GSM rail for voice and data traffic?

The GSM-R network is a cellular-structure radio system with 19 frequencies for the traffic from the radio base stations to the mobile radio communications systems (down link) and 19 frequencies for the traffic from the mobile radio communications systems to the radio base stations (up link).

What is difference between GSM and GSM-R?

GSM-R, however, was modified from GSM, a public radio network standard, for use in railway operations – a private mobile radio environment. Public radio networks, however, cater to a totally different audience, being designed for general public use and individual calls, with no requirement for fast call set-up times.

What frequency does GSM use?

GSM-900 and GSM-1800 are used in most of the world. GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing of 45 MHz is used.
