Abstract
A proactive energy-saving processing in an access point (AP) device is described. The AP monitors/computes usage/operating parameters (load factors) of the AP, and based on the obtained parameters, adjusts one or more AP operating parameters to reduce power consumption. The process is proactive in the sense that the current conditions in the AP do not require scaling back AP functionality. Nonetheless, the AP can scale back some functionality to reduce its power consumption, proactively, despite the absence of a need to do so.
Claims24
A method for reducing power consumption by an access point (AP), the AP including a plurality of radios operating in different radio frequency bands, the method comprising:
- for each radio in the plurality of radios:
- making measurements of one or more radio usage parameters pertaining to the radio and/or one or more other radios in the plurality of radios;
- based on at least a portion of the measurements of the one or more radio usage parameters, adjusting one or more operating parameters of the radio from first respective operating states to second respective operating states, wherein the first respective operating states correspond to a full-function operating mode and wherein the second respective operating states correspond to a reduced functionality mode;
- making additional measurements of the one or more radio usage parameters pertaining to the radio and/or the one or more other radios;
- based on at least a portion of the additional measurements of the one or more radio usage parameters, adjusting the one or more operating parameters of the radio from the second respective operating states to third respective operating states corresponding to an increased functionality mode;
- and
- making measurements of one or more wired interface usage parameters pertaining to one or more wired interfaces of the AP, wherein:
- the adjusting of the one or more operating parameters of the radio from the first respective operating states to the second respective operating states is further based on the measurements of the one or more wired interface usage parameters, and
- the adjusting of the one or more operating parameters of the radio from the second respective operating states to the third respective operating states is further based on the measurements of the one or more wired interface usage parameters.
