Patent ID: 7558604

Claim:
An apparatus comprising: an arrangement that facilitates network communication for at least one client which communicates with a wireless access point, wherein a wireless interface of said at least one client transitions between at least two power states, said arrangement that facilitates network communication traffic further comprising: an arrangement that determines a configuration of said at least one client for transitioning between said power states, wherein said arrangement is adapted to perform one or more of the following (a), (b) and (c): (a) ascertain a time of receipt of an initial beacon via: transmitting a probe packet; measuring a response delay of said at least one client subsequent to transmission of a probe packet; and continuing to measure response delays of said at least one client subsequent to transmission of additional probe packets until the response delay is substantially equivalent to a predetermined minimum round trip time; (b) ascertain at least one interval between which successive beacons are received by the at least one client via: transmitting a probe packet; measuring a response delay of said at least one client subsequent to transmission of a probe packet; calculating a new beacon multiple and awaiting a new beacon if the response delay is not substantially equivalent to a predetermined minimum roundtrip time; and continuing to measure response delays of said at least one client subsequent to transmission of additional probe packets until the response delay is substantially equivalent to a predetermined minimum roundtrip time; and (c) ascertain a client time interval for staying in active mode via: transmitting a pair of probe packets; measuring a response delay of said at least one client subsequent to transmission of a probe packet; adjusting a packet sent interval and awaiting a new beacon if response delays are not substantially equivalent to a predetermined minimum roundtrip time; and continuing to measure response delays of said at least one client subsequent to transmission of additional probe packets until the response delay is substantially equivalent to a predetermined minimum round trip time.
