European Union Agency for Railways publishes report by LS telcom on co-existence of GSM-R system with future LTE system


Lichtenau / Baden, Germany – The European Union Agency for Railways has recently published a report by LS telcom on the possibility of using the ER/R-GSM spectrum by other radio communication systems for railways in coexistence with the existing GSM-R system operated in that frequency band. The objective of the study was to find out whether new spectrum is required for a successor system or whether band sharing during migration from GSM-R to its successor would be feasible.

Thomas Chatelet, ERTMS Project Officer at the European Union Agency for Railways, said, “Their study will contribute to informed decision-making for the railway industry’s future spectrum requirements. We were very satisfied with the work carried out by LS telcom and we look forward to working with them again.”

LS telcom reviewed several technologies, which met the rail industry’s needs, and identified LTE / LTE Advanced as the only feasible technology currently available. The study further showed that the implementation of an LTE system within the R-GSM band in co-existence with the current radio system is unlikely to be feasible unless a number of mitigating measures are taken.

LS telcom carried out feasibility and compatibility analysis, which were complemented by capacity and coverage simulations and by laboratory measurements made by the Dresden University of Technology.

The study concluded that the extent and necessity of the mitigation methods should be tested through field trials. Furthermore, an evaluation of the potential degradation of the quality and capacity of the existing GSM-R system should be conducted to identify whether the potential degradations caused by the implementation of an LTE carrier are acceptable. Future demand for data for rail services should also be examined to determine whether the resulting capacity is sufficient.

About European Union Agency for Railways
The European Union Agency for Railways, formerly known as European Railway Agency (ERA), was established in 2004 to devise the technical and legal framework for creating a Single European Railway Area (SERA) as mandated under European Union law. ERA’s core activities are creating a harmonised approach to safety, removing technical barriers, advancing the single European Train Control and Communication System (ERTMS), and promoting simplified access for customers for the European rail sector.

With the entry-into-force of the technical pillar of the 4th Railway Package in 2016, the mandate of the Agency has been extended to that of a European authority, issuing rail vehicle authorisations, safety certificates, and approval for ERTMS infrastructure. After a period of legal transposition into EU Member State law, these changes are expected to take effect by 2019/2020.
