Radio planning and transmission network design of GSM-R system for the railway line

One of the biggest projects aimed at integration of the infrastructure of the European Union is the implementation of the European Rail Traffic Management System on the railway network of the Member States. Its goal is to unify the railway traffic control system in European countries, increase safety as well as ensure the interoperability of rail transport. One of its main components is ERTMS/GSM-R subsystem. This article presents the structure of the GSM-R system as well as associated systems. Services offered by the system are discussed. The rules of planning radio networks including the propagation model are described. The final part of the paper contains an example of radio planning for GSM-R system for selected railway line covering computations as well as simulation tests. The simulation of the radio coverage was prepared with the usage of ICS Telecom software.
