INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Selective activation of communications services on power-up of a remote unit(s) in a wireless communication system (WCS) based on power consumption is disclosed. To avoid a remote unit drawing more power than is allowed and risking shutting down all of its communications services, after a remote unit in the WCS is powered-up to start its operations, the remote unit selectively activates its different communications services. The remote unit selectively activates communications services based on the power consumption of the remote unit to avoid the remote unit drawing more power than is allowed. If activating a next communications service would cause the remote unit to draw more power than is allowed, the remote unit discontinues activating additional communications services. In this manner, the already activated communications services in the remote unit can remain operational without risking powering down of the remote unit and discontinuing all of its communications services. ## Claims ### Claim 1 A remote unit for a wireless communication system (WCS), comprising: a plurality of communications service circuits each configured to process received respective communications signals for a respective communications service in the WCS;
