FRMCS (Future Railway Mobile Communication System)

  • , par Paul Waite

It is the next-generation global standard for railway communication, developed by the International Union of Railways (UIC) to replace the current GSM-R (Global System for Mobile Communications – Railway), which is based on 2G technology.

Key Points About FRMCS:

  1. Purpose:

    • Provide a modern, future-proof mobile communication system for railways.

    • Support operational communications (train control, signaling, voice, and data).

    • Enable advanced digital rail services (e.g., automated train operation).

  2. Technology Base:

    • Built on 3GPP (3rd Generation Partnership Project) 5G standards.

    • Uses Mission Critical Services (MCX) like Mission Critical Push-To-Talk (MCPTT), Mission Critical Data (MCData), and Mission Critical Video (MCVideo).

  3. Benefits Over GSM-R:

    • Higher bandwidth for real-time video and data.

    • IP-based, enabling flexible and secure communication.

    • Longer lifecycle, avoiding obsolescence (GSM-R is being phased out globally).

    • Support for automation and digital signaling systems like ERTMS/ETCS.

  4. Deployment Timeline:

    • First specifications released by 3GPP and UIC in recent years.

    • Pilot projects underway in several countries (e.g., France, Germany, Finland).

    • Expected large-scale deployment across Europe in the late 2020s or early 2030s.

Let me know if you want a comparison between FRMCS and GSM-R or an overview of how FRMCS integrates with signaling systems like ERTMS.
