Railway Mobile Radio

Railway Mobile Radio (“RMR”) is a dedicated non-public radio communication system for voice and data services supporting railway operations. It comprises two radio systems: GSM-R (Global System for  Mobile Communications – Railways) and FRMCS (Future Railway Mobile Communication System) that may be implemented both at the same time or each of them independently.  Decision (EU) 2021/1730 requires Member States to designate and make available on a non exclusive basis the paired frequency bands 874.4-880.0 MHz, 919.4-925.0 MHz (the “900 MHz Band”) and 1 900 – 1 910 MHz (the “1.9 GHz Band”) for RMR (based on national demand).

ComReg Document 25/60 contains the RMR licensing guidelines and application process.

RMR licences are governed by the S.I. No. 417 of 2025 Wireless Telegraphy (Railway Mobile Radio Licence) Regulations 2025 (S.I. 417 of 2025).
