Abstract

The present invention relates to the field of communications, and more particularly to methods and a system for providing high-speed communications on a high-speed railway. The technical result is a better quality communication channel provided by train-to-ground radio relay links The claimed system for providing high-speed communications on a high-speed railway comprises an internal and an external data exchange network. The internal network unites tail-end radio frequency modules mounted in the rear part of a train and equipped with narrow-band antennae, head-end radio frequency modules mounted in the front part of the train and equipped with narrow-band antennae, and switching equipment capable of processing signals from said modules and of providing network devices connected to said equipment with access to the external data exchange network. The external data exchange network unites base stations equipped with narrow-band antennae, said base stations being capable of establishing communication with the tail-end and head-end radio frequency modules in the train and being arranged in proximity to the railway clearance along the path of travel of the train. The antennae of the base stations and of the radio frequency modules in the train are configured to radiate radio waves in a short millimeter wave band.
