INTERNET ACCESS
Internet Access
Providing an on board Internet access has become the new standard of comfort. For passengers, a Internet access allows a smooth and confort during their travel by train.
For train operators, this service is a competitive advantage and gives an additionalss argument to entice new passengers by upgrading their level of confort onboard.
Passenger Internet Access (PIA) system set up a wireless link between the train and the ISPs to provide internet access (WIFI) to the passengers and even a special access (superuser) to the crew.

NETWORK
Network
With the technical development of the on-board subsystems, there has been in parallel a demand for more reliable and powerful networks.
The network is really the frame on which the most advanced systems are assembled, supporting the transfer of multimedia information and all necessary data information to integrate everything on a train.
Networks need to provide a high bandwidth and capability to manage all the information that the other SEPSA’s onboard systems handle : Communication systems, Control systems, Passenger Information systems and Security systems, as well as other third party systems.
The particularities of the network of a train, when being a composition of vehicles which are in motion, make it should be able to handle the traffic and avoid IP conflicts, even if the train composition is reordered and physically modified.
