Trials of FRMCS, the New Railway Communications Standard to Begin in 2025—2026

The impending trials of FRMCS (Future Railway Mobile Communication System), a groundbreaking 5G-based communication standard, signify a pivotal step forward in railway communication technology.

While considerable progress has been made, challenges persist as CEPT (European Conference of Postal and Telecommunications Administrations) has standardized the 1900 MHz band for FRMCS, yet its adoption remains incomplete across member countries. Notably, the UK is currently navigating the process of reclaiming spectrum from incumbent Mobile Network Operators (MNOs) to facilitate FRMCS deployment.

To fully leverage the potential of the new 1900 MHz band alongside the existing 900 MHz band, railway infrastructure operators will need to enhance network density.

In a recent article, Richard Haas-Journalist/Analyst @PolicyTracker, delved into the potential of spectrum sharing beyond traditional trackside areas. By leveraging exclusion zones that can extend up to 50 miles or more, depending on the context, there is optimism about enabling the sharing of the 1900 MHz band allocated for FRMCS deployment across Europe. This innovative approach could pave the way for enhanced connectivity and efficiency in railway communications systems.

Historically, regulatory and governmental interest in spectrum sharing with railways has been minimal. However, with the identification of the 1900 MHz band for FRMCS, new avenues for collaboration emerge, signaling a paradigm shift in spectrum management.
