High Availability Train To Wayside Communication System For Subway Application Using 802.11X

Résumé

Wireless transmission for train to wayside communication is now a reality, including for the train control application. However subway applications entail specific constraints, such as environment, high speed mobility, need for a rugged data communication system with very high availability of the links and specific requirements in terms of quality. In addition, the operation of such system requires more throughputs for offering additional new services such as video or other data communication for other sub-systems. Finally, the life of the system shall be at least of 30 years. The challenge is to design a whole system and an architecture integrating products from the 802.11 family (WiFi). These products should be available on the market and they still have to meet all the requirements mentioned above. The present approach focuses on modularity, redundancy architecture and control of the link budget. Dedicated optimized algorithms address mobility features.
