摘要： Methods and apparatus to manage power consumption in wireless devices are disclosed. A disclosed example apparatus comprises performing a first received signal strength indicator (RSSI) scan to determine a beacon interval and a first beacon time for a wireless channel, calculating a second beacon time for the wireless channel based on the beacon interval and the first beacon time, and performing a second RSSI scan for the wireless channel during a time interval that includes the calculated second beacon time. In some examples, the wireless channel is a wireless channel that was previously identified as active, is a wireless channel that previously had the highest received power level, and/or is selected from a list of popular or frequently used channels. Additionally or alternatively, when a wireless channel with sufficient signal level is identified, scanning for additional channels is not performed.

摘要： A method provides forward compatibility hooks for DFS and TPC for WLAN, so that the same mechanisms can be employed (with only minor changes/additions) for other regulatory domains, other bands, and/or other purposes. The current IEEE 802.11 h standard defines mechanisms for dynamic frequency selection (DFS) and transmit power control (TPC) that may be used to satisfy regulatory requirements for operation in the 5 GHz band in Europe. The present method provides a format to allow other bands, and relates to the supported channels element, channel switch announcement element, and the Basic/CCA/RPI histogram request/report. The method optionally reserves more than 3-bits in the Basic report (Map subfield).

摘要： A novel and useful apparatus for and method of improving idle connection state power consumption in wireless local area network (WLAN) system using variable Beacon data advertisements. The invention takes advantage of the fact that Beacon contents to not change significantly between consecutive messages. Access points determine the size of the variable portion of their Beacon messages and include this size information in a special Variable Beacon Data Information Element in the Beacon message itself. The station reads the contents of this information element and uses the size information to determine at what point it is able to abort the reception of the Beacon message and turn off it's receive radio thereby saving power.
