Abstract:
1. A method for reducing handoff latency in a mesh wireless local area network, the method comprising: in anticipation of a probable handoff by a mobile station currently associated with a particular mesh access point in said network, sending an activation alert from said particular mesh access point to one or more other mesh access points in said network; determining at said particular mesh access point that the quality of a wireless link between said mobile station and said particular mesh access point has dropped below a predetermined threshold, thus anticipating said probable handoff; if a receiving mesh access point of said one or more other mesh access points is in a low-power state upon receipt of said activation alert, entering a higher-power state in said receiving mesh access point upon receipt of said activation alert; and if said receiving mesh access point is not in said low-power state upon receipt of said activation alert, refraining from entering said low-power state in said receiving mesh access point upon receipt of said activation alert.
