Requirements for Wireless Technology on Rolling Stock

摘要

This paper gives an overview of railway specific requirements on wireless technologies and discusses the influence of different product life cycles in railway industry and communication technology. The main challenges are the heterogeneous communication infrastructure at the wayside and the specific requirements on vehicle speed and geographical characteristics. The current state of European research and international standardization activities for on-board communication equipment is summarized and the need for a standardized application interface on the railway vehicle and at the wayside is explained. Finally, challenges for future research and development in railway applications are identified.
