Method and system for providing high speed communications on high speed railways

The invention relates to the field of communication, in particular to a method and a system for providing high-speed communication on a high-speed railway. The technical result is a better quality communication channel provided by a "vehicle-to-ground" class radio relay link. The claimed system for providing high-speed communications on high-speed railways includes internal and external data exchange networks. The internal network combines a tail radio frequency module (mounted at the rear of the train and equipped with a narrow directional antenna), a head radio frequency module (mounted at the front of the train and equipped with a narrow directional antenna) and a switching device (capable of processing signals from the modules and providing access to the network device associated with the device to an external data switching network). An external data exchange network combines a base station and a narrow directional antenna together, the base station being capable of establishing communication with tail a
