    摘要： A battery-powered WLAN communication device has an activity sensor operable to identify an available packet. A PHY module is awakened to begin receiving the packet. The PHY module decodes a full MAC address from a MAC portion of a header of the packet. A MAC address parser receives the MAC address and determines whether the packet is to be received by comparing the full MAC address to a MAC address of the WLAN communication device. The MAC address parser is awakened to perform the comparing and shutdown after. Packets to be received include beacon packets. A hardware centric MAC separate from the MAC address parser has a beacon processor capable of being awakened from a shutdown state to process a beacon packet. The PHY module, the MAC address parser, and the beacon processor module are operable to be awakened and shutdown independently of each other and of a microprocessor.

    摘要： Hardware-based beacon processing. A hardware-centric medium access control (MAC) device includes a packet receiver and a beacon processor. The packet receiver receives a plurality of packets comprising at least one beacon packet. The beacon processor receives packets of the plurality of packets and filters out unwanted packets of the plurality of packets without requiring the use of other components of the hardware-centric MAC device and without requiring the use of a microprocessor.

    摘要： An apparatus comprises a network physical layer and an activity sensor for sensing a packet and activating the network physical layer from shutdown. The network physical layer decodes a PHY header portion and a media access control header portion of a packet header. A MAC has a fixed hardware media access plane implementing IEEE 802.11 series MAC functionality and couples to a microprocessor. A MAC address parser receives the MAC header portion of the packet, for processing the MAC header portion of the packet, and for activating the MAC from a shutdown in response to recognizing a MAC address within the MAC header portion of the packet, such that the MAC is not activated if the MAC parser does not recognize the MAC address, wherein the MAC is operable, after activation, to perform MAC functionality without the microprocessor and to provide data from the packet to the microprocessor.
