2. UIC ERTMS World Conference Istanbul, 2 April 2014 Robert Sarfati – SYSTRA UIC Operators Group Chairman 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  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 Pre- emption (eMLPP)  All functionalities available for GSM-R including  General Packet Radio Service (GPRS)  Enhanced Data Rates for GSM Evolution  Enhanced Location Dependent Addressing (eLDA)  Enhanced Railway Emergency Call (eREC)  Short Message Service to Functional Number Railway functional Requirements (EIRENE) GSM enhancements for railways ( ETSI EN301515) ) Standard GSM functionality l Applications

3. UIC ERTMS World Conference Istanbul, 2 April 2014 Robert Sarfati – SYSTRA UIC Operators Group Chairman 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 / 921- 925 MHz) with extension possible within (873-915 / 918-960 MHz) and other GSM frequency bands* such as the 1800 MHz for worldwide application. Functionalities ensured by GSM-R * As listed in ETSI TS 100 910

9. UIC ERTMS World Conference Istanbul, 2 April 2014 Robert Sarfati – SYSTRA UIC Operators Group Chairman 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 on- board equipment without this having an impact on the 'safety critical signalling path.  Today ETCS applications work with GSM-R circuit- switched 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. 9

10. UIC ERTMS World Conference Istanbul, 2 April 2014 Robert Sarfati – SYSTRA UIC Operators Group Chairman 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. 10

14. UIC ERTMS World Conference Istanbul, 2 April 2014 Robert Sarfati – SYSTRA UIC Operators Group Chairman 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.
