  • Publication number: 20150208349
    Abstract: A station, a method performed by a station and a corresponding method performed by an access point (AP) of a network to allow the station to operate a wireless local area network (WLAN) radio in a sleep state until the WLAN radio is ready to receive a beacon from the AP. The station includes a low power (LP) radio configured to receive a wake up signal from an AP of a network to which the station is connected. The station further includes a WLAN radio configured to operate in a sleep state until the WLAN radio receives an indication from the LP radio that the wakeup signal has been received, wherein WLAN radio is further configured to operate in a fully awake state after receipt of the indication to receive a beacon from the AP indicating a data transmission is pending for the station.

  • Patent number: 8804685
    Abstract: Provided is dual mode operation by a communicating device in wireless network. The communicating device selects a radio frequency (RF) channel and a physical layer type. The communicating device processes signals received via the selected RF channel based on the selected physical layer type. The communicating device may determine whether a beacon frame has been detected base on the signals that were received via the selected RF channel and processed based on the selected physical layer type. When a frame is not detected, the communicating device may determine a signal energy level for the received signals. The communicating device may establish an association with an existing network based on detection of the beacon frame or the communicating device may transmit an originating beacon frame based on the determined signal energy level.

  • Patent number: 8638263
    Abstract: A technique to extend antenna coverage pattern of a planar antenna array. In one instance a reflector is disposed above the planar antenna array and in another instance a lens element is disposed above the planar antenna array. The reflection or refraction of RF signals allows antenna coverage pattern to be extended in a horizontal direction parallel to the planar surface of the antenna array and beyond a coverage pattern that is typically not available, without such reflection or refraction of the RF signal.
