Abstract
System-wide uplink band gain control in a distributed antenna system (DAS) based on per-band gain control of remote uplink paths in remote units is disclosed. In one embodiment, for each uplink band in the DAS, a gain control system receives remote uplink band power measurements for each remote uplink path for the uplink band. Based on these power measurements, the gain control system determines if the uplink gain of all of the remote uplink paths of the plurality of uplink paths of the uplink band should be adjusted. If the uplink gain of the remote uplink paths of the uplink band should be adjusted, the gain control system directs a remote uplink gain control circuit for each remote uplink path of the uplink band to adjust the uplink gain by a defined remote uplink band gain level.
