How does it actually work?

SNCF has equipped each TGV Lyria train with antennae which enable the 4G network to be picked up from providers. But did you know that at high speed, the connection to the signal lasts less than one minute?

This is why Internet access points have been installed every 3 km on all the main high-speed lines. This means there are more than 1,000 antennae to ensure the connection.

By way of explanation

Imagine several hundred people in your front room, most of them connected to your wireless box. This would be a large number, and gives you an idea of the way it works on the train.

The more people who are connected, the lower the speed. To ensure that all passengers benefit from the free Wi-Fi with a good flow rate, we offer some advice.
