Operations Communications and FRMCS

Mission-critical and FRMCS-ready

Frequentis brings control centre communications, mission-critical services and broadband technologies together in one integrated portfolio for rail operators and infrastructure managers. Built on a standard-compliant architecture and backed by decades of mission-critical railway communications experience, Frequentis provides a trusted, step-by-step path to FRMCS. This approach protects the installed legacy systems of current train operations while enabling a confident transition to next-generation railway communications.

Designed for those who keep railways running

The Frequentis Fixed Terminal System (FTS) is our proven GSM-R-based legacy dispatcher solution, built around real control-centre workflows and trusted for safety-critical railway voice communication. FTS integrates seamlessly into existing GSM-R infrastructures and provides reliable, standards-compliant operational communications for daily railway operations.

With the Operations Communications Manager (OCM), Frequentis introduces the next-generation dispatcher platform for the FRMCS era. OCM extends dispatcher capabilities into a fully digital, bearer-independent environment, enabling new mission-critical services, enhanced interoperability, and scalable capacity for modern rail operations. Together, FTS and OCM support a controlled and gradual transition from legacy GSM-R to next-generation FRMCS communications.

Built to evolve. Ready every day.

The modular FTS dispatcher adapts to evolving operational requirements while fitting seamlessly into existing GSM-R communication architectures. Its proven design ensures stable day-to-day operations while supporting ongoing digitalisation. OCM, the next-generation web-based dispatcher, enables the integration of new operational services and prepares control centres for future FRMCS communications – allowing operators to modernise step by step without disrupting existing operations.

Extending operations into the broadband era

This 3GPP‑compliant mission‑critical communication solution brings secure broadband voice, video and data to railway operations. Proven interoperability – validated through plug tests, proofs of concept and customer trials – supports a low‑risk evolution from GSM‑R to FRMCS via a fully standardised Interworking Function (IWF) aligned with the FRMCS architecture. With cloud‑native deployment capability where scalability matters and on‑premise installation where control is required, the Frequentis FTS ecosystem connects control rooms and field operations in real time – ensuring performance, continuity and future‑ready broadband capability.

Trusted evidence for safety-critical operations

Frequentis provides reliable and auditable recording of safety-critical railway voice communications for rail control centres. Clear capture and structured access to recordings support incident review, regulatory obligations and operational transparency – helping rail operators meet legal recording requirements.

Your route to FRMCS

The shift from GSM-R to the Future Railway Mobile Communication System (FRMCS) is transforming railway communication across Europe. Frequentis is enabling railway organisations to manage the transition safely.
