Claim:
1. A wireless communications system, comprising: a plurality of remote units; a head-end unit coupled to the remote unit over a plurality of optical communications paths, the head-end unit including a controller configured to: monitor a plurality of remote units in a first power configuration, wherein determine that each remote unit of a first subset of the plurality of remote units has a user activity level below the second predetermined threshold; in response to the determination that each remote unit of the first subset has a user activity level below the second predetermined threshold, determine a second power configuration wherein each remote unit of a second subset of the plurality of remote units has a second power state lower than the first power state of the respective remote unit, such that each remote unit of the second subset has a third coverage range smaller than the second coverage range of the respective remote unit, wherein the third coverage ranges of the remote units of the second subset and the first coverage ranges of the remote units outside the second subset cover all of the predetermined coverage area; and reduce power usage to each remote unit of the second subset of the plurality of remote units from the first power state to the second power state of the respective remote unit such that the plurality of remote units are in the second power configuration.
