Although the SNCF offers a wifi service on board its Inoui TGVs, accompanied by a portal giving access to services and content (press, films, games, podcasts, etc.), the quality of this service is often criticised for insufficient bandwidth, blackouts, white zones<\/strong>... \" Wifi doesn't work!<\/em>\"This is a phrase that is frequently heard on board our trains. Even though the situation has improved considerably since the system was deployed ten years ago, with the carrier having invested tens of millions of euros in this technological area.<\/p>\n\n\n\n

Wifi on board, a technological feat<\/h2>\n\n\n\n

The rail company has therefore decided to remedy these malfunctions. The TGV trains are currently equipped with antennae on the roofs and fibre optics that pick up the 4G\/5G networks of the telecoms operators from terminals located close to the different railway lines and spaced about 3km apart. Visit complexity<\/strong> for the modems and Sim cards on the train lies in the fact that the train travels at 100 metres per second, changing towers every 30 seconds. In addition to speed, SNCF is constrained by the operators' coverage of the country and the number of frequencies they make available. The poor quality of the bandwidth is also correlated with the number of users on board, as a train can carry up to a thousand passengers, of whom around 400 will be connected.<\/p>\n\n\n\n
