Background: GSM-R an European choice
 In Europe, existing standard technologies were considered for the new
digital radio technology, The choice of GSM was finalized in 1995.
 GSM-R standards were developed based on GSM R99 technology and
included all railways specific requirements and an allowance of a
specific additional frequency range
 Enhanced Location Dependent Addressing
(eLDA)
 Enhanced Railway Emergency Call (eREC)
 Short Message Service to Functional Number
 Functional Numbering
 Location Dependent Addressing
 High speed – up to 500 km/h
 Voice Group Call Service (VGCS)
 Voice Broadcast Service (VBS)
 Enhanced Multi Level Precedence and Preemption (eMLPP)
 All functionalities available for GSM-R including
 General Packet Radio Service (GPRS)
 Enhanced Data Rates for GSM Evolution

Functionalities ensured by GSM-R
GSM-R is a worldwide standard, developed within the frame of the
GSM ETSI standards to include Rail & Transport needs.
- It includes a dedicated radio spectrum for exclusive rail use, all
over Europe.
- It is the bearer for ETCS and Track-to-Train radio .
- It allows for evolution towards Packet Switching GPRS/EGPRS
- It includes features specific for Railways operations .
- It includes a dedicated European Frequency Band (876-880 / 921925 MHz) with extension possible within (873-915 / 918-960 MHz)
and other GSM frequency bands* such as the 1800 MHz for
worldwide application.
* As listed in ETSI TS 100 910

From an European standard
In most of the European Countries GSM-R is in operation and
ETCS L2 roll out is relying on GSM-R:
70,000 km of track are in GSM-R operation just in Europe and
84,000 km more are planned to be covered in addition.*)

To a worldwide standard
GSM-R is expanding worldwide: 138,000 km are planned to
be covered outside Europe. *

From the European Legislation perspective
MoU ERTMS– A Memorandum of Understanding ERTMS was
signed between the European Commission, European Railway
Agency and the Rail Sector Organisations :
 The Parties note the commitment of the GSM-R Industry
Group members to the long-term support of GSM-R
technology, at least until 2025. Nevertheless
telecommunications systems usually have a much shorter
life cycle than signalling systems. For this reason, it should
be possible to replace the 'telecommunications part of onboard equipment without this having an impact on the
'safety critical signalling path.
 Today ETCS applications work with GSM-R circuitswitched services. It does seem possible, however, to use
packet-switch systems (e.g. GPRS) and, in the longer
term, other IP-based standards, without impacting on the
ETCS specifications.

From the European Mandates perspective
 Two Mandates were notified and endorsed
by CEN/CENELEC and ETSI.
Mandate M/483 – Mandate for
programming and standardization
addressed to the European Standardization
Organizations under Directive 2008/57/EC
in the field of the interoperability of the rail
system within the European Union.
Mandate M/486 – Mandate for
programming and standardization
addressed to the European Standardization
Bodies in the field of urban rail.

Conclusion
 The analysis showed that communication technology
evolution is not complete, but the IP based technology is
the only stable platform.
 The worldwide evolution shows that GSM/UMTS is still a
long term technology for voice and preserves more than
80% of railways assets while evolving toward IP.
 The roadmap should be « railways needs evolution »
based, not « technology only » driven.
 It shall, if possible, address “all transport” needs, and if
feasible worldwide through a 3GPP type organization.
 GSMR-IP is Global, allows from the Shelves delivery,
ensures Multi-supplier environment, is Reliable, prepared
for Innovation and answers Promises.
