ABSTRACT:
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.
