Patent ID: 8619652

Claim:
A method of power saving in a wireless network for transmitting uncompressed audio/video (A/V) data, the method comprising: detecting a low or no channel activity in the wireless network by a station; entering into a deep sleep power saving (DSPS) mode by the station, wherein the DSPS mode includes one or more periods of inactive state during which the station does not transmit a beacon, wherein the DSPS mode includes a first sub-mode and a second sub-mode, wherein the first sub-mode comprising a passive DSPS mode (PDSM) and the second sub-mode comprising an active DSPS mode (ADSM); adaptively computing a current sleep period for a current sleep window cycle based at least on a maximum allowed sleep period and one or more previous sleep periods by the station; and remaining in the deep sleep mode by the station for the duration of the computed current sleep period or until a new channel activity is detected in the wireless network, wherein the PDSM comprising: passively scanning for channel activity for K superframes during a scheduled wake period, wherein the station terminates the PDSM when channel activity is detected, otherwise the station returns to an inactive state, where K comprises an integer; and the ADSM comprising: announcing the ADSM to all stations in the wireless network by transmitting DSPS messages indicating DSPS status.
