Patent ID: 8031647

Claim:
A system for transceiving radio frequency signals, the system comprising: a multiplexing apparatus at a base of a tower and communicatively coupled to a cable, the cable being communicatively coupled to at least one antenna at the top of the tower, the multiplexing apparatus including a transmitter path, a portion of a receiver path, and a transceiver path portion, wherein the multiplexing apparatus includes: a transmitter filter communicatively coupled between the cable and a first-band base transceiver station, a band pass filter portion including at least one band pass filter communicatively coupled between the cable and at least one second-band base transceiver station, and a first receiver filter communicatively coupled between the cable and a low noise amplifier; a second receiver filter; and the low noise amplifier at the base of the tower, the low noise amplifier operable to amplify signals in a first spectral region, the low noise amplifier communicatively coupled to the portion of the receiver path of the multiplexing apparatus, wherein the multiplexing apparatus is configured to pass signals in the first spectral region between the cable and the first-band base transceiver station via the portion of the receiver path of the multiplexing apparatus and the low noise amplifier, and wherein the multiplexing apparatus is further configured to pass signals in a second spectral region between the cable and the at least one second-band base transceiver station via the transceiver path portion, wherein the transmitter filter is configured to pass signals in the first spectral region from the first-band base transceiver station to the cable, wherein the first receiver filter is configured to pass signals in the first spectral region from the cable to the first-band base transceiver station via the low noise amplifier and the second receiver filter, wherein each filter in the band pass filter portion is configured to filter and pass signals in respective portions of the second spectral region between the cable and a respective one of the at least one second-band base transceiver station.
