摘要： A wireless network device includes a transceiver module, a beacon miss module, and a control module. The transceiver module is configured to transition the wireless network device from an inactive mode to an active mode at a wakeup time. The wakeup time is a predetermined time period before a time at which a delivery traffic indication message (DTIM) beacon is expected by the wireless network device. The beacon miss module is configured to count a number of DTIM beacons missed by the transceiver module during each of a first predetermined period and a second predetermined period. The first predetermined period is shorter than the second predetermined period. The control module is configured to selectively adjust the wakeup time during operation of the wireless network device based on the number of the DTIM beacons missed by the transceiver module during each of the first predetermined period and the second predetermined period.

摘要： A system includes a host interface module and a power management module. The host interface module is configured to receive configuration information from a host processor of a wireless device. The configuration information indicates that the host processor is to (i) operate in a power save mode, and (ii) in response to the wireless device receiving data of a predetermined category from a wireless network, transition from the power save mode to an active mode. The power management module is configured to generate a first signal in response to the wireless device receiving data of the predetermined category from the wireless network. The first signal transitions the host processor from the power save mode to the active mode in which the host processor processes the data of the predetermined category.
