<p>System for offering radio coverage in an environment enclosed for radio-transmission purposes, for the benefit of VHF-radiotelephone traffic, comprising a number of base transceiver stations which are mounted within said enclosed environment at a number of locations, and which are capable of simultaneous transmission. All base transceiver stations are connected to one another by way of a fixed internal four-wire house-telephone line, by way of a concentrator unit, and the transmitters of the base transceiver stations retransmit the signal of an identified transmitting radiotelephone, which signal is simultaneously received on one or more receivers of the base transceiver stations, at the same frequency on all locations, by way of the concentrator unit.</p> |
