1. A method of managing power in a remote unit of a distributed communication system, the method comprising:
- installing at least one communication service module in the remote unit, the remote unit comprising at least one optical-to-electrical converter and at least one antenna;
connecting at least one power supply to the remote unit;
opening each of a plurality of switches located in the remote unit and associated with a plurality of communication services supported by the remote unit to deactivate all communication services in the remote unit such that no communication service is active in the remote unit;
measuring, using a power sensor located in the remote unit, a first power consumption level indicative of no communication services being active in the remote unit;
closing at least one of the plurality of switches to selectively activate at least one of the plurality of communication services in the remote unit that requires power for transmitting and receiving communication signals, where the at least one of the plurality of communication services consumes power such that a second power consumption level is generated;
measuring, using the power sensor, the second power consumption level, the second power consumption level being indicative of the at least one of the plurality of communication services being active in the remote unit;
calculating a maximum available power for the remote unit based at least in part on the measured first power consumption level and the measured second power consumption level;
comparing the maximum available power for the remote unit to an expected power demand of all communication services active in the remote unit; and
reducing transmission power for one or more communication services if the calculated maximum available power is insufficient.

Abstract
Power management techniques in distributed communication systems are disclosed herein. Related components, systems, and methods are also disclosed. In embodiments disclosed herein, services within a remote unit of the distributed communication system are selectively activated and power consumption is measured. From at least two measurements, a maximum power available may be calculated and compared to power requirements of the remote unit.
