Patent ID: 7400912

Claim:
In a wireless data communication system, wherein mobile units associate with access points for data communication therewith, and wherein said data communication system operates according to a protocol wherein said mobile units are arranged to conserve power by signaling an associated access point that the mobile unit is entering power save mode, and wherein said associated access point buffers data packets for mobile units in power save mode until it receives a polling signal from a corresponding mobile unit, a method of communicating audio or video representative data between a mobile unit and an associated access point comprising: signaling said associated access point that said mobile unit is in a power save mode; powering down a transmitter and receiver of said mobile unit at intervals corresponding to a selected period of time corresponding to the duration of at least an audio or video signal forming an audio or video signal data packet; accumulating of at least audio or video signal data in said mobile unit for a time interval corresponding to said selected period of time to form at least audio or video representative transmit data packets; buffering at least audio or video representative receive data packets at said access point; and powering up said mobile unit transmitter and receiver for communication with said associated access point for a communication session, said communications sessions occurring at intervals corresponding to said selected period of time and including communicating said accumulated transmit data packets and said buffered receive data packets between said mobile unit and said associated access point.
