Enabling Europe’s migration from GSM R to FRMCS:
Building the RF foundation for the digital rail era
Europe’s railway networks are preparing for a once‑in‑a‑generation transformation. After more than two decades of service, GSM‑R — the 2G‑based communication technology that has reliably supported operational safety across the continent — is approaching its end of life. To meet the growing demands for capacity, automation, resilience, and interoperability, the industry is now transitioning to the Future Railway Mobile Communication System (FRMCS). Powered by 5G technology, FRMCS is designed to unlock the next era of digital rail, enabling mission‑critical services.
