Abstract:
1. A band combiner unit (BCU) to be utilized for a plurality of carriers, comprising: a plurality of carrier modules (CMs) each configured to be connected to a single corresponding base transceiver station (BTS) or bi-directional amplifier (BDA) for a corresponding one of the carriers, wherein the CMs of the BCU are each configured to be connected to a different corresponding BTS or BDA than each of the other CMs of the BCU, and wherein each of the CMs is configured to transmit downlink signals from the corresponding BTS or BDA, to adjust the downlink signals, and to transmit the downlink signals to a first combiner, and to receive uplink signals from a second combiner, to adjust the uplink signals, and to transmit the uplink signals to the corresponding BTS or BDA; the first combiner configured to combine the downlink signals transmitted from each of the CMs, and to transmit the combined downlink signals to a distributed antenna system (DAS); the second combiner configured to split a combined uplink signal transmitted from a DAS, and to transmit the split uplink signals to corresponding ones of the plurality of CMs according to the respective carrier; and a band combiner unit controller (BCUC) for monitoring and controlling the plurality of CMs.
