Abstract:
A multi-sectorized base transceiver station system for increasing system capacity in a mobile communication system by sectorizing base transceiver stations covering a particular coverage area within a cell, said multi-sectorized base transceiver station system comprising:a first base transceiver station having a first narrow beam directional antenna, a second narrow beam directional antenna, and a third narrow beam directional antenna, where said first, second, and third antennas serve first, second, and third sector areas of said particular coverage area, respectively, and where said first, second, and third antennas are separated by 60Â° with respect to each other; and a second base transceiver station having a fourth narrow beam directional antenna, a fifth narrow beam directional antenna, and a sixth narrow beam directional antenna, where said fourth, fifth, and sixth antennas serve fourth, fifth, and sixth sector areas of said particular coverage area, respectively, where said fourth, fifth, and sixth antennas are separated by 60Â° with respect to each other, said first base transceiver station and said second base transceiver station are separated by 180Â° with respect to each other, and where none of the sector areas overlap.
