Abstract
Power management in a distributed communications system, such as a distributed antenna system (DAS), that includes determining user activity at remote units of the DAS. When user activity in one or more remote units falls below or above a specified threshold, power usage by the one or more remote units is reduced or increased accordingly. The power usage may reduced and/or increased by turning select remote units on or off, by increasing or reducing an operating voltage of one or more power amplifiers, and/or by turning select multiple-in, multiple-out (MIMO) front ends on or off. Power may be reduced such that wireless coverage within a specified area is maintained.
Claims22
A method of managing power in a distributed antenna system (DAS), comprising:
- determining that at least one remote unit of the DAS is experiencing user activity below a first predetermined threshold;
- and
- in response to the determination that the at least one remote unit is experiencing user activity below the first predetermined threshold, causing power usage by the at least one remote unit to be reduced.
A controller configured to be connected to at least one of a head-end unit or a first remote unit of a plurality of remote units of a distributed antenna system (DAS), the controller further configured to:
- determine that at least one remote unit of the plurality of remote units is experiencing user activity below a first predetermined threshold;
- and
- in response to the determination that the at least one remote unit is experiencing user activity below the first predetermined threshold, reduce power usage by the at least one remote unit.
A non-transitory computer-readable medium having instructions for directing a processor to perform a method, comprising:
- determining that at least one remote unit of a distributed antenna system (DAS) is experiencing user activity below a first predetermined threshold;
- and
- in response to the determination that the at least one remote unit is experiencing user activity below the first predetermined threshold, reducing power usage by the at least one remote unit.
