White paper GPRS for ERTMS - General Packet Radio Sevice for European Rail Traffic Management System

The purpose of this document is to provide an outline assessment of the need to enhance GSM-R network capacity and to review the key technology solutions available. The GPRS for ERTMS White Paper provides the outline business case for supporting the use of the General Packet Radio Service (GPRS) for the European Rail Traffic Management System (ERTMS) and other data applications and it specifically considers the potential for introducing GPRS to support ETCS. The document also includes proposals for steps to be undertaken to prove whether GPRS (and the introduction of IP-based protocols) is feasible as future method for data transmission in the railway environment and it proposes an outline plan for the development of working systems.
