Methods and system for providing high-speed communication on high-speed railway

A method for providing high-speed communication on a high-speed railway, in which base stations connected to an external data transmission network are installed along a route of the train, the base stations being equipped with narrow beam antennas and being capable of communicating with head and tail radio frequency modules installed on the train, the head and tail radio frequency modules being equipped with narrow beam antennas and integrated into an internal data transmission network,

• the base stations location relative to the railway gauge provides for direct visibility between the antennas of the base stations and the antennas of the radio frequency modules installed on the train, and
• wherein a pre-determined distance between base stations is selected in accordance with a corresponding first Fresnel Zone calculation, the first Fresnel zone being free of obstacles, the method includes the following steps:
• emit radio waves in the range of short millimeter waves on the antennas of the base stations and the radio frequency modules of a moving train;
• establish communication channels between a first head module, a first tail module and the base station closest to them located behind, while establishing a communication channel between a second head module and a nearest base station located ahead;
• before the train head has passed by the base station located ahead, a communication channel is established between a second tail module and this base station located ahead of the train tail, with which the second head module was in communication;
• with radio signals, an exchange of which is carried out through the established communication channels, processed on a switching equipment connected with the radio frequency modules, and an access of network devices on the train to the external data transmission network is provided.

A system for providing high-speed communication on a high-speed railway, which includes

• internal and external data exchange networks, wherein the internal network combines tail radio frequency modules installed on a tail of the train, equipped with narrow beam antennas,
• head radio frequency modules installed on a head of the train, equipped with narrow beam antennas, and
• switching equipment capable of processing signals from the head radio frequency modules and the tail radio frequency modules and providing connected network devices with access to the external data exchange network;
• the external data exchange network combines base stations with narrow beam antennas,
• wherein the base stations are able to establish communication with the tail radio frequency modules and head radio frequency modules of the train and are installed along a route of the train in such a way that the location of the base stations relative to a railway gauge provides for direct visibility between the narrow beam antennas of the base stations and the narrow beam antennas of the radio frequency modules installed on the train;
• wherein a pre-determined distance between base stations is selected in accordance with a corresponding first Fresnel Zone calculation, the first Fresnel zone being free of obstacles,
• wherein the narrow beam antennas of the base stations and the radio frequency modules installed on the train are tuned to emit radio waves in a range of short millimeter waves.
