The Electronic Railway and FRMCS. A Substitution for GSM-R

The thought of the electronic railway arrived into getting with the first operational implementation of GSM-R in 1999. The Intercontinental Union of Railways (UIC) explain GSM-R as ‘the bearer for the first Digital Railway Radio Communications System’. GSM-R is a next generation (2G) electronic radio method centered on the professional GSM cell telephony technique tailored for use on railways. Firms such as Motorola modified their pretty productive 2G terrestrial mobile infrastructure merchandise to assistance GSM-R. GSM-R has been hugely profitable across Europe, currently being employed in more than 20 countries throughout 100,000km of tracks. The selection of modern railway communications methods is anticipated to enhance in the future several many years due to the ongoing installations throughout the earth together with locations this kind of as Algeria, Saudi Arabia, India, China and Australia.

GSM-R know-how is now around 20 a long time outdated, and suppliers are actively setting up to conclusion-of-lifestyle help for equipment. This means that software updates and hardware replacements will cease at the close-of-existence date. The most up-to-date 5G technologies have been designed to assistance flexible cellular broadband programs, supporting the two minimal bit charge and quite higher little bit level connections.

Enter, FRMCS – Future Railway Cellular Communications Procedure. Commenced in 2012 with the publication of a UIC named the Person Prerequisite Specification (URS) to capture the user prerequisites for communications in the railway throughout the world. FRMCS is a lot more than are placement for GSM-R, it represents a opportunity to revolutionise communications in a modern-day railway technique.

At the time of writing, the most recent URS is FU 7100-v5.., posted in May 2020. These user specifications are translated into Functional Necessity Specification (FRS) and in transform the Program Prerequisite Specification (SRS). The SRS is vital to satisfy the European Directives with regard to interoperability throughout European railways. Next, the use situations can be presented to ETSI and 3GPP for ‘gap analysis’.

Even though the UIC states that FRMCS must be technology agnostic, it isn’t going to make sense to create a new technological innovation when 3GPP have a suite of expectations focused on Mission Critical Communications (MCX).

The FRMCS project is well underway with a FRMCS demonstrator planned for 2023 and the very first countrywide trials beginning in 2024. The positive aspects of FRMCS are quite major to a rail operator, nonetheless the timescales are incredibly shorter and there are a selection of troubles experiencing the effective implementation of FRMCS.

FRMCS is one more area of Vital Nationwide Infrastructure in which Wray Castle are intercontinental industry experts. We have been serving to telecommunications industry experts maintain on the foremost edge of at any time modifying know-how because 1958.
