Patent ID: 8289888

Claim:
A system for cellular communications comprising a switch subsystem and a base station subsystem which are interconnected therebetween, the system comprising Q base stations, where Q is an integer, which are interconnected with a controller of base stations, and mobile stations being coupled through radio channels of operating frequencies of the system for cellular communications with antenna input-output of operating frequencies of corresponding base stations; herewith each base station comprises a serially coupled antenna-feeder module of operating frequencies, a module of digital transceivers of operating frequencies and a digital unit of distribution and switching of messages whose first input-output is a first input-output of a connection of a base station with the controller of base stations via a corresponding communication line, wherein in the subsystem of base stations are introduced K groups of line repeaters with a transition of a channel capacity of the system, and in a structure of at least one base station is introduced a retransmission unit for outputting an additional channel capacity at frequencies of retransmission of radio channels of the system for cellular communications being interconnected by its first input-output with antenna input-output of the base station for its communication through radio channels at frequencies of retransmission being different from the operating frequencies with its corresponding groups of line repeaters with a transition of a channel capacity of the system, and by a second input-output being interconnected with a digital unit of distribution and switching of messages of the base station, wherein the antenna input-output of the module of operating frequencies is the antenna input-output of the base station for its communication at operating frequencies with the mobile stations, herewith, each group of line repeaters with a transition of a channel capacity of the system includes L intermediate line repeaters and M terminal line repeaters with a transition of a channel capacity of the system, wherein the intermediate line repeaters and the terminal line repeaters are interconnected therebetween through radio channels at frequencies of retransmission, and at operating frequencies being interconnected with the corresponding mobile stations directly or via an additional repeater of signals of operating frequencies of the system, where Lâ‰§1, Mâ‰§1, such that said retransmission unit comprises an additional transceiver operating in a frequency range other than operating frequencies to thereby expand the channel capacity of the base station without using the operating bands of frequencies of cellular communication.
