PCT No. PCT/FI96/00050 Sec. 371 Date Sep. 25, 1996 Sec. 102(e) Date Sep. 25, 1996 PCT Filed Jan. 25, 1996 PCT Pub. No. WO96/23370 PCT Pub. Date Aug. 1, 1996The coverage area of the base station of a cellular radio system is expanded in a very simple and easily implementable way by utilizing the cabling present in a community antenna system, so that the community antenna system and a repeater connected thereto are used for transmitting telecommunication signals between the base station and a subscriber unit served by the system. The base station can also transmit on the control channel to the repeater information as to which radio channel and which power level the repeater should at each time repeat the signals it receives, to ensure that the signals intended for a specific subscriber unit are repeated on a traffic channel and power level suitable for the purpose. The base station can reduce the power level used by the repeater to such a level that a plurality of repeaters utilizing the same traffic channel can be placed close to one another without disturbing one another. |
