Radio systems

ÖBB-Infrastruktur AG plans, builds and operates various radio systems. We provide digital train radio (GSM-R, in future FRMCS) and operational mobile radio for rail operations. We also operate radio equipment for public communication (mobile radio, public WLAN) and emergency radio for emergency services (TETRA).

Communication in rail operations

Digital train radio and operational mobile radio form the basis for voice and data communication in rail operations, such as voice communication in train and shunting operations as well as data communication for ETCS (European Train Control System). The Europe-wide conversion of the radio standard from GSM-R to FRMCS is also driving forward and promoting digitalization in rail operations (e.g. automatic train operation, ATO).

GSM-R radio

GSM-R is currently the radio standard on European railroads. Here you will find further information and relevant documents on GSM-R, such as the network expansion plan, information on existing and planned startups and contact details for your inquiries. You can also find out how to order SIM cards.

FRMCS radio

The Future Railway Mobile Communication System based on 5G technology is the successor system to GSM-R and the future Europe-wide standard for mobile communication in rail operations. For further information, the implementation schedule and relevant documents, please click here.

Operational mobile radio

Here you will find further information on the types of application of the operational mobile radio as the basis for voice communication in train and shunting operations.

Mobile communication

As part of ÖBB Infrastructure AG's digitalization strategy, the range of Wi-Fi services and mobile network coverage is being continuously expanded and improved. Here you can find detailed information about public Wi-Fi at the station and the expansion of public mobile communication along the railroad lines.
