BssSIM - GSM-R Core and Radio Access Simulator

PRISMA’s solution for ERTMS testing is BssSIM-R, a single device test-bed simulating both the core and radio access of a real GSM-R wireless network. BssSIM-R  reproduces all kinds of normal and abnormal behaviour you can expect from a real network, such as overloads and allows the debugging of interworking issues.  It’s also used for live demonstration of the ERTMS application to customers  by using real terminals and any SIM profile (both live and test SIMs are available).



The European Railway Traffic Management System (ERTMS) is a major industrial project developed in close cooperation with the European Union. ERTMS aims at replacing the different national train control and command systems in Europe. The deployment of ERTMS will enable the creation of a seamless European railway system and increase European railway’s competitiveness.

An essential component of  ERTMS is the GSM-Railway (GSM-R), a  mobile communications standard for railway operations.

GSM-R is a radio system for providing voice and data communication between the track and the train, based on standard GSM using frequencies specifically reserved for rail application with certain specific and advanced functions.
