Method and system for a repeater network that utilizes distributed transceivers with array processing

A device comprises a plurality of distributed transceivers, a plurality of distributed beamformers, a baseband processor, and a network management engine. The distributed transceivers perform beamforming in a radio frequency band. The distributed beamformers, however, performs beamforming in an intermediate frequency band. Each of the distributed transceivers is coupled to a corresponding one of the distributed beamformers. Each transceiver-beamformer pair is coupled to the baseband processor utilizing a same communication medium such as a cable. For transmission, a data stream generated at baseband is converted to intermediate frequencies. With a low-power transmission, the distributed beamformers transmit the data stream wirelessly in the intermediate frequencies to a receiving device. With a normal-power transmission, the distributed transceivers transmit the data stream to the receiving device in the radio frequency band. The transceivers and the beamformers are turned OFF whenever not being used. A high-throughput communication link may be established through resource sharing.
