Box TGV: The OCEA Consortium Meets the Challenge of Internet Access in High-speed Trains

PARIS, January 18, 2011 /PRNewswire-FirstCall/ -- Launched on December 1 by France's SNCF rail company, the Box TGV service is now enabling passengers using the eastern route of its high-speed network to benefit from a unique multimedia and Internet service. Box TGV uses technology and infrastructure developed by the OCEA consortium, led by Orange Business Services and including Eutelsat, Alstom and Capgemini.

The technological achievements realised by the consortium have risen to the challenge of ensuring service at high speed in a high voltage electrical environment, and integrating the system's maintenance into the overall maintenance schedules of a high-speed network with no impact on the rotation of trains.

Assembling competence from four experts in their field

As prime contractor for the overall programme, Orange Business Services assured the integration of services and the communications infrastructure, and used the R&D teams of Orange to develop the mobile router for connectivity between the satellite and WiFi network. As the operator and integrator, Orange Business Services also provides access, operation and maintenance services of the on board WiFi network and the Internet access.

"Providing Internet connectivity at 320 kph was a new challenge that we are all proud to have successfully addressed for the SNCF," commented Philippe Roger, Vice President Large Accounts France at Orange Business Services. "The Internet access solution proposed by Box TGV is emblematic of our skills and our capacity to drive innovation that opens the benefits of the Internet to the broadest range of users."

Eutelsat is supplying the satellite component of the network. The satellite antennas installed on the roof of the trains were specifically developed to comply with available headroom, and can operate at speeds up to 360 kph in a high voltage electrical environment. The system operates via Eutelsat's ATLANTIC BIRD(TM) 2 satellite, using an advanced spread-spectrum technique, which makes it possible to layer up data flows transmitted to and from the trains. The service is available on the entire TGV East network serving France, Germany, Luxembourg and Switzerland, and currently supplies a total throughput of 30 Mbps, which can be increased as required.

Alstom brought its experience of railway standards and equipment integration. It is responsible for supply and installation of the Wi-Fi equipment and the servers which process and store the on board multimedia portals. Alstom also installed the LAN network, which is connected to the servers feeding the carriages of each train and the WiFI hotspots in each carriage.

Capgemini, through its Telecom & Media sector in France, carried out the end-to-end supervision application, from the ground servers to hardware and software equipments on board of each of the French high speed train wagons. The operators thus have a global vision of the working conditions of the system, and the necessary information to correct malfunctions. Capgemini has also developed geolocation softwares that can provide information on the speed and location displayed on the portal.
