GSM – R

GSM-R is a digital communications system, based on the use of GSM technology, which has been developed to replace the existing analogue VHF/UHF rail network communications system. GSM-R, in contrast to public mobile GSM, constitutes a non-public communications network for use by European railway operators.

GSM-R licences are governed by the Wireless Telegraphy (GSM for Railway Licence) Regulations, 2013 (S.I. 213 of 2013).
