Delivering Broadband Internet Access for High Speed Trains Passengers Using the New WiFi Standard 802.11n for Train-to-ground Communications

摘要

This paper presents an experimentation carried out by SNCF and Orange Labs which aimed at e-valuating the performance of new generation WiFi IEEE802. 11n technology for the implementation of broadband trainto-ground communications solutions. The major results of the project are presented, showing 802. 11n potentialities for the foreseen services. This experimentation was part of the 'TGV Communicant programme' , launched by SNCF in 2003 in order to find technical solutions for the delivery of broadband Internet access services for passengers onboard its TCV high speed trains, and which was crucial in the validation of technical solutions having lead to the first commercial Internet service for passengers onboard SNCPs TCV, which will be open in Q4 2010 onboard the trains of the TCV East European Service.
