Patent ID: 7272362

Claim:
A multi-sector in-building repeater in communication with a base station, the multi-sector in-building repeater comprising: a master transmitting unit for receiving multi-sector signals of a carrier frequency from the base station, mixing the multi-sector signals with different transmission intermediate frequency signals, and outputting the mixed multi-sector signals to a same transmission line; a plurality of slave transmitting units, each of which receives the mixed multi-sector signals, for extracting from the mixed multi-sector signals sector signals assigned to the multi-sector signals from the transmission line, converting the extracted sector signals into high frequency signals, and transmitting the high frequency signals through an antenna; a plurality of slave receiving units for mixing different receiving intermediate frequency signals with sector signals of carrier frequencies received from the antenna, converting the mixed signals into multi-sector signals of different receiving intermediate frequency bands, and outputting the converted signals to the same transmission line; a master receiving unit for mixing the multi-sector signals received from the plurality of slave receiving units, the multi-sector signals having been transmitted through the same transmission line from the plurality of slave receiving units and converted into different receiving intermediate frequency band signals, with different intermediate frequency band signals, separating each of the mixed multi-sector signals, converting the separated multi-sector signals into receiving carrier frequency signals, and outputting the converted signals to the base station; a master transmitting/receiving separator for separating transmitted/received signals of the master transmitting unit from transmitted/received signals of the master receiving unit; and a distributor for distributing the mixed multi-sector signals received from the master transmitting unit to the plurality of slave transmitting units, receiving the multi-sector signals of different receiving intermediate frequency bands provided from the plurality of slave receiving units, and transmitting the multi-sector signals of different receiving intermediate frequency bands to the master receiving unit.
