Abstract
An access point coupled to an Ethernet port detects whether it is using power over Ethernet, and if so, adjusts its operation to maintain its power requirements within those capable of being supplied by power over Ethernet. The access point might include a detector capable of determining if external power is available, or if that access point is operating using power over Ethernet. If the access point is operating using power over Ethernet, it adjusts the operation of its radios, gracefully degrading those radios from (first) both radios operating in 3x3 mode, to (second) a first radio operating in 3x3 mode and a second radio operating in 2x2 mode, to (third) both radios operating in 2x2 mode. The power adaptation circuit may also throttle clock speeds in the system (processor or peripherals), or shut down or idle various peripherals to lower power consumption for the duration consumption is high.
