The objective of the proposed activity is to develop a demonstration of a hybrid satellite communications and terrestrial network for use on trains.
The EOMST system developed by 21Net enables Internet services on board high-speed trains. The system uses multiple communication technologies to access the internet: cellular, WiFi and satellite. A Mobile Access Router manages the links depending on their availabilities.
The main objective of the SAET project is to define an engineered satellite-based network architecture for the provision of multimedia services on-board European trains.
In this project 21Net designed, built and trialled a Wi-Fi access system for use on trains with the capability to support broadband internet and intranet access as well as local multimedia content such as short films, up-to-the minute news, etc. The initial target market is high-speed trains in Western Europe where journey times allow for its use.
