MIRRORING FUTURES: MCX VERSUS FRMCS
Of all the many disciplines covered under the Railway Systems umbrella, none has evolved so dramatically, and so rapidly, over the last two and half decades as has railway mission-critical telecommunications systems.
In the past five years, we have seen railway operators around the world begin to deploy new radio networks based on advanced radio mobile (LTE). A number of these implementations have followed the Mission-Critical Services (MCX) standards defined by 3GPP Releases 13 and 14 which are currently supporting railway operational voice services and Automatic Train Control applications.
At the same time, the International Railway Union has been working in defining a Future Railway Mobile Communications System as part of 3GPP Release 16 standards which is set to become the successor technology of GSM-R as the standard radio bearer for ETCS.
This white paper explores the relationship between these two mobile radio sets of standards, their differences and similarities, potential migration paths between them and the extent at which the 5G roadmap will impact each of the two.
Read on, and you’ll agree, railway telecommunications engineers have a most exciting decade ahead.
