TWT usage with optimum power consumption

A method of reducing power consumption in a low power Wi-Fi device, comprising:

• negotiating target wait time (TWT) parameters with an access point, wherein the TWT parameters include a TWT wake interval duration, an announce mode of operation and a TWT wake duration, wherein the TWT wake duration defines a duration of a TWT service period;
• estimating a tolerable latency period associated with an application executing on the low power Wi-Fi device, wherein the latency period is longer than the TWT wake interval and wherein a plurality of beacons are transmitted during each latency period;
• configuring the low power Wi-Fi device to exit a low power mode once per latency period to receive one beacon from the access point and remain in low power mode for others of the plurality of beacons;
• and
• returning to low power mode after receiving the one beacon.

A low power Wi-Fi device, comprising:

• a Wi-Fi network interface;
• a processing unit;
• and
• a memory device in communication with the processing unit comprising an application executing on the low power Wi-Fi device and also comprising instructions, which when executed by the processing unit, cause the low power Wi-Fi device to:
• negotiate target wait time (TWT) parameters with an access point, wherein the TWT parameters include a TWT wake interval duration, an announce mode of operation and a TWT wake duration, wherein the TWT wake duration defines a duration of a TWT service period;
• estimate a tolerable latency period associated with the application executing on the low power Wi-Fi device, wherein the latency period is longer than the TWT wake interval and wherein a plurality of beacons are transmitted during each latency period;
• configure the low power Wi-Fi device to exit a low power mode once per latency period to receive one beacon from the access point and remain in low power mode for others of the plurality of beacons;
• and
• return to low power mode after receiving the one beacon.
