Topology and reliability of GSM-R radio installation

On railway tracks equipped with ETCS level 2, the availability requirements on the GSM-R radio system is very high since it is essential for the transmission of the movement authority to the driver’s cab. To achieve the targets, the topology of the radio system (base stations, locations of antenna, repeater, connections to the base stations BSC and MSC, power supply and air conditioning) had to be updated. The enhanced topology has successfully been implemented and is in commercial operation in the Loetschberg base tunnel and on the main line between Mattstetten and Rothrist. It will be used as a standard for new radio installations on the SBB network.
