An electronic device includes a first receiver configured to receive a first wireless signal, and a first timing module configured to wake up the first receiver from a first sleep state and to generate a synchronization signal indicating a wakeup time of the first receiver. The electronic device also includes a second receiver configured to receive a second wireless signal, and a second timing module configured to receive the synchronization signal and to wake up the second receiver from a second sleep state based on the synchronization signal.

Synchronizing wakeup operations in electronic devices

An apparatus and method for improving WLAN spectrum efficiency and reducing interference by flow control comprising determining if at least one data packet is entering a receive buffer; determining if the utilization of the receive buffer is greater than an overflow threshold; determining if a wireless device is in power save mode, wherein the wireless device comprises the receive buffer, a WLAN transceiver and a send buffer for storing packets from an interface module to the WLAN transceiver; determining if the send buffer is empty; setting a power management bit to '1' in either a top-most packet in the send buffer or a NULL packet; and using the WLAN transceiver for transmitting either the top-most packet or the NULL packet to an access point.
