Abstract
A method for routing data between at least one guided vehicle and a ground network, wherein said vehicle moves on a track between at least a first and a second communication terminal arranged on the ground along the track. The terminals are capable of exchanging data streams between a ground network and at least one routing module onboard the vehicle. A transmission quality measurement for a first signal between the first terminal and the routing module is carried out periodically, a transmission quality measurement for a second signal between the second terminal and the routing module is carried out periodically, a measurement of the available data flow rate for the first signal between the ground network and the routing module is carried out periodically, a measurement of the available data flow rate for the second signal between the ground network and the routing module is carried out periodically, a routing path for at least a portion of the data between the ground network and the routing module is also periodically determined via at least one of the communication terminals if it has a measured signal quality higher than a predetermined threshold and a data flow rate higher tha…
