MULTI-CARRIER INTEGRATION APPARATUS FOR DISTRIBUTED ANTENNA SYSTEM

摘要

A band combiner unit includes a plurality of carrier modules (CMs) each configured to be connected to a base transceiver station (BTS) or bi-directional amplifier (BDA) for corresponding ones of the carriers, wherein each of the CMs is configured to transmit downlink signals from the corresponding BTS/BDA, adjust the downlink signals, and transmit the downlink signals to a first combiner, and to receive uplink signals from a second combiner, adjust the uplink signals, and transmit the uplink signals to the corresponding BTS/BDA, the first combiner configured to combine the downlink signals from the CMs, and transmit the combined downlink signals to a distributed antenna system (DAS), the second combiner configured to split a combined uplink signal from a DAS, and transmit the split uplink signals to corresponding ones of the CMs, and a band combiner unit controller for monitoring and controlling the CMs.
