Abstract
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.
