Existing and Future Needs for Railways Applications
• Now:
– GSM-R is a major railway technology used for train-to-ground voice and data
communications, part of ERTMS (European Rail Traffic Management System)
– In France, GSM-R covers 16 000 km of lines, representing 80% of traffic flows
– GSM-R lifecycle coming to its end, with uncertain vendor support beyond 2030
• The Future:
– FRMCS (Future Radio Mobile Communication System) is the successor of GSM-R
– FRMCS could be based on 3GPP LTE/5G system in order to address a large set of
applications specified by “UIC FRMCS Project”:
1 - Critical Communications
2 - Performance Communications
3 - Business Communications
4 – Critical Support5 – Performance
Support6 – Business Support

Train-to-Everything Communication Project
– Securing the highest level of safety for people is SNCF’s 1st commitment
– SNCF in partnership with Qualcomm are evaluating the potential use of
C-V2X technology for railways applications

C-V2X Testing: Train-to-Railway Crossing and Car-to-Railway Crossing
– Tests conducted on SNCF rail route from Vitry to Montereau
– C-V2X communication system set-up on SNCF test train
– RSU setup close to Livry-sur-Seine train station
– C-V2X communication system set-up on a car

C-V2X Communication System on the Train
• The train is continuously sending and receiving CAM messages using
PC5
• All data is recorded by the DP and sent to the “Trial Server Platform”
using 4GAntenna Location
