Abstract
A radio communication system, more especially for mobile handsets in a microcellular system, wherein a single TDMA transceiver (10) connects to a plurality of separate RDPs (14, 16, 18), one at a time, in different timeslots, so that secondary stations (20, 22) within the coverage area of an RDP can communicate with the shared transceiver during the timeslot allotted to that secondary station.
Claims
1. A radio communication system comprising signal feeder cable means for connecting a base-station TDMA transceiver to a plurality of geographically separate RDPs wherein, one at a time, the RDPs are connected to the shared transceiver during different timeslots so as to allow secondary stations within the coverage area of an RDP to communicate with the shared transceiver via the RDP antenna during the ti eεlot allotted to that secondary station, the shared transceiver transmitting a unique and different identity from each different RDP.
2. A system according to claim 1, wherein the signal broadcast by an RDP contains information to advise secondary stations of the time slots available on the RDP.
3. A system according to claim 1 or claim 2, wherein signals on the feeder cable means are transmitted at the same radio frequency as that used between the secondary station and the RDP.
4. A system according to any of claims 1 to 3, having antenna diversity at the RDP which is remotely controlled.
5. A system according to any of claims 1 to 4, when appendant to claim 2, having amplifier means in the feeder cable means being either a bi-directional switched Tx/Rx transmission amplifier or unidirectional trans¬ mission amplifiers.
6. A system according to any of claims 1 to 5, wherein signals on the feeder cable means are transmitted at an optical frequency modulated by the radio frequency signal.
7. A system according to any of claims 1 to 6, wherein the feeder cables are either arranged in a bus or star configuration, or in a hybrid configuration of the two.
8. A system according to any of claims 1 to 7, having base-station or secondary station signal quality measurement means enabling transfer of a secondary station in use from one RDP to another.
9. A system according to claim 8, wherein the base- station samples the signal qualities of RDPs neighbouring the one in use during the synchronisation period in order to make a handover decision.
10. A system according to any of claims 1 to 9, wherein additional transceivers can be added to an existing or new feeder cable.
11. A system according to any of claims 1 to 10, wherein control signals are multiplexed onto the feeder cable means or carried on an auxiliary cable.
