Abstract:
1. An integrated circuit comprising: a transceiver module configured to, at predetermined times, transition a wireless network device from an inactive mode to an active mode, and wherein the predetermined times are based on a clock used by the wireless network device while operating in the inactive mode; a beacon miss module configured to count a number of delivery traffic indication message (DTIM) beacons missed by the transceiver module during each of a first predetermined period and a second predetermined period, wherein the first predetermined period is shorter than the second predetermined period, and wherein the predetermined times at which the wireless network is transitioned from the inactive mode to the active mode do not occur during either of the first predetermined period or the second predetermined period; and a control module configured to adjust the predetermined times at which the wireless network device is transitioned from the inactive mode to the active mode based on the number of the DTIM beacons missed by the transceiver module during each of i) the first predetermined period and ii) the second predetermined period.
