Next generation

The reliability and interoperability of GSM-R with the benefits of IP communication (MCX, FRMCS)

GSM-R has been the global communications standard for over 20 years. While GSM-R has progressively been a secure platform for voice and data communication, Siemens Mobility has also developed the hardware-ready platform that will support the next-generation requirements of FRMCS (Future Rail Mobile Communication System)

Highly configurable communication devices for the railway

The Siemens Mobility range of GSM-R cab radios, display panels, applications and accessories delivers safe and secure voice and data communications. The cost-effective products are designed for ease of installation, replacement, maintenance and operation. Siemens Mobility offers retro-fittable radios and standard rack-mounted units.

Cab radio products

Dual Mode Capability

All Airlink 600, 500 and 400 Series can be transformed into dual-mode radios by simply adding an additional processor card. Dual Mode Capability enables a seamless migration to 5G FRMCS and allows the following features:


  • GPS/GNSS module
  • 5G module (3GPP Rel.17)
  • Ethernet port
  • Embedded accelerometers
  • Wi-Fi module
  • Cab radio MTBF 100k hours
  • Optional additional LTE data module

Control panels: Relevant information and intuitive interaction at all times

Siemens Mobility's driver control panels benefit from long-standing development and research. All design decisions are founded on real-world operations. Train drivers' comments and assessments are being fed back into product development.


RailXplore smart applications

Airlink cab radios can be used as a platform for applications that offer completely new ways to support drivers, train staff and operators without requiring new hardware. If a Siemens Mobility cab radio is not in use, stand-alone devices are also available, enabling the use of applications independent of a cab radio system.

Cab Radio Remote Management Terminal

Allowing administrators to manage cab radios remotely

The Siemens Mobility Cab Radio Remote Management Terminal (CRMT) lets administrators manage cab radios remotely via an IP connection. This allows for easy updates of a cab radio’s software, phone book entries and message templates. The management terminal is able to keep track of a whole fleet’s cab radios via their types and serial numbers. Error logs and language files can also be administered. Maintenance and management tasks can be scheduled to run while a radio is idle, while automating certain tasks is also possible. Our Cab Radio Management Terminal is offered in two connectivity solutions to suit a customer’s needs.
