Nokia Siemens Networks says that it has successfully completed the fourth set of interoperability testing of its GSM-Railway (GSM-R) infrastructure with an unnamed supplier against requirements specified by the European Union (EU).
The EU has mandated interoperability of the GSM-R system in its “Technical Specification for Interoperability of the Control, Command and Signaling Subsystem” (CCS TSI) which, in addition to GSM-R, encompasses the European Train Control System (ETCS). GSM-R interoperability tests have been in place since 2002, and multivendor configurations have been validated in order to give railways access to a more competitive supplier market.
Although GSM-R is a complex system, interconnected GSM-R networks and multivendor GSM-R configurations work without any interoperability problems.
“Interoperability and standardization within the EU makes the railway sector more attractive for both passengers and freight transporters,” says Dirk Lewandowski, head of Railways Solutions at Nokia Siemens Networks. “The project underlines our global leadership role in building strong, interoperable railway communications network across the world and it strengthens our position as a leading mobile infrastructure provider.”
