UDcast ensures performance and security of Internet service on TGV's high-speed trains in France

SOPHIA-ANTIPOLIS, France, April 8, 2008 – UDcast, a leading provider of wireless IP broadcast solutions, announced today that its UDgateway® satellite-delivered Internet access appliance is installed in the Wi-Fi equipment and servers as part of a mobile Internet trial in three trains of the TGV East of SNCF (High-Speed Trains, East of the French National Railway Network).

The trial is a hybrid satellite Wi-Fi solution created specifically for the needs of the SNCF services portal. The solution assures service continuity up to 320 km/h (173mph), as well as maximizes flow, allowing a higher number of users to log in to the service at the same time. Orange Business Services are the official contractors for the project, encompassing service integration, communication structure and part of the portal's content. UDcast is Orange's provider for the trial.

'UDcast solutions enable satellite Internet services that are efficient and low cost in several mobile environments such as civil and military ships, trucks and other mobility projects,' said Jas Saini, CEO of UDcast. 'We are very happy to participate in the trial with Orange contributing to the service on board of High-Speed Trains in France.'

The services portal offered in SNCF trains is based on a non-stop Internet connection that is highly secured and efficient. These aspects are ensured thanks to UDcast UDgateways that are integrated by Orange Business Services into their servers.

In terms of performance, the UDgateway enhances IP transmissions that are otherwise slowed by the satellite's delay. UDcast's equipment adapts protocols like TCP and HTTP in order to optimize the bandwidth and increase the rapidity of file sending; the data compression mechanisms allow faster data exchanges and use less bandwidth. The UDgateway can encrypt all the communications and transmissions established between TGV and the satellite Internet service provider, as well as integrate a firewall function protecting onboard networks from eventual Internet attacks.
