  • Power management in a WLAN infrastructure
    Patent number: 7702303
    Abstract: A wireless local area network includes multiple access points with overlapping coverage, and modes of different power consumption are available to the access points. It is assessed whether the traffic load of the network may be adequately supported using fewer access points in an active mode. If so, the traffic load is redistributed from certain active access points among the remaining access points in the active mode. The certain access points are switched into a mode of lower power consumption than the active mode. Similarly, it is assessed whether the traffic load of the network is adequately supported by the current number of access points in an active mode. If not, certain access points which are in a mode of lower power consumption are switched to the active mode. The traffic load is redistributed among the access points in the active mode including the certain access points.
