Abstract:
1. A distributed antenna system comprising: a hub unit configured to receive an original downlink signal comprising a plurality of downstream frequency bands, each of the plurality of downstream frequency bands associated with a respective radio frequency channel; and a remote antenna unit that is communicatively coupled to the hub unit; wherein the hub unit is configured to communicate a downstream transport signal from the hub unit to the remote antenna unit, wherein the transport signal is derived from the original downlink signal received at the hub unit; wherein the remote antenna unit uses the downstream transport signal to generate a downstream radio frequency signal for radiation from an antenna associated with the remote antenna unit, wherein the downstream radio frequency signal comprises at least a subset of the plurality of downstream frequency bands; wherein the remote antenna unit comprises automatic gain control functionality operable to automatically control at least one of a gain in the remote antenna unit and a slope in the remote antenna unit; and wherein the remote antenna unit uses a data structure comprising a plurality of entries, each of the entries associating at least one setting for the automatic gain control functionality in the remote antenna unit with a target level for a pilot tone included in the downstream transport signal; wherein at least one setting for the automatic gain control functionality in the remote antenna unit is derived from:
