MULTI-RADIO WIRELESS TRANSCEIVER POWER CONSERVATION
A wireless transceiver having radios that support wireless communications with associated stations on a corresponding wireless local area network (WLAN). The wireless transceiver also includes: a utilization monitoring circuit, an association targeting circuit, and a power backoff circuit. The utilization monitoring circuit monitors communications between each of the radios and its associated stations. The association targeting circuit identifies, from the monitored communications of the utilization monitoring circuit, an underutilized one of the radios as a target radio for re-associating stations currently associated with at least one other radio and initiates the re-association with the target radio of the stations currently associated with the at least one other radio. The power backoff circuit reduces power to the at least one other radio.
1 . A wireless transceiver comprising:
a plurality of components coupled to one another to form transmit and receive chains of a plurality of radios each of which radios supports wireless communications with associated stations on a corresponding wireless local area network (WLAN);
a utilization monitoring circuit monitoring communications between each of the plurality of radios and its associated stations;
an association targeting circuit identifying, from the monitored communications of the utilization monitoring circuit, an underutilized one of the radios as a target radio for re-associating stations currently associated with at least one other radio among the plurality of radios, and initiating the re-association with the target radio of the stations currently associated with the at least one other radio; and
a power backoff circuit responsive to the association targeting circuit to reduce power to the at least one other radio of the plurality of radios.
