  • Publication number: 20230120992
    Abstract: A method may include determining, by an access point, which stations among multiple stations are permitted access to a wireless communication medium in a subsequent uplink frame. The method may also include broadcasting an uplink map to the stations, where the uplink map identifies a first station of the multiple stations as permitted access to the wireless communication medium. The uplink map may also identify an allocation of the subsequent uplink frame for the first station. The method may also include, during the allocation of the subsequent uplink frame allocated to the first station, receiving: an acknowledgment (ACK) of downlink data transmitted to the first station, uplink data, a resource allocation request from the first station requesting access to a second subsequent uplink frame, and/or combinations thereof.

  • Patent number: 11128544
    Abstract: An example method may include receiving, from a wireless sniffer, sniffer data for a window of time, where the sniffer data may include wireless signal data. The method may also include obtaining corresponding access point data from an access point in a wireless network for at least part of the window of time for which the sniffer data is received. The method may additionally include analyzing the sniffer data and the corresponding access point data to assess performance of the wireless network.

  • Patent number: 11070994
    Abstract: A wireless access point (WAP) configured to supporting wireless communications with station nodes on a selected communication channel of an associated wireless local area network (WLAN). The WAP includes multiple multiple-input multiple-output (MIMO) transmit and receive paths. The WAP is to intermittently switch one of the multiple MIMO receive paths to concurrently process both communications on a selected communication channel together with monitoring communications on unselected channels of the multiple communication channels associated with the WLAN.

  • Patent number: 10321341
    Abstract: A wireless access point (WAP) configured to support a wireless home network among multiple wireless devices over a shared wireless communication medium on a selected channel. In an embodiment of the invention the WAP includes a channel tracker configured to track performance metrics over time for at least the selected channel; and to predict based on the tracked performance metrics at least one of: a predicted time of an impending channel changeover requirement in which a projected demand for the selected channel exceeds a projected capacity thereof and a predicted time of an impending monitoring interval for monitoring an unselected channel with relatively minimal disruption of communications on the selected channel. In another embodiment of the invention the WAP includes receive path components configured to concurrently process both communications on the selected channel together with monitored communications on an unselected channel.

  • Patent number: 9082400
    Abstract: Techniques for generating a video sequence of a person based on a text sequence, are disclosed herein. Based on the received text sequence, a processing device generates the video sequence of a person to simulate visual and audible emotional expressions of the person, including using an audio model of the person's voice to generate an audio portion of the video sequence. The emotional expressions in the visual portion of the video sequence are simulated based a priori knowledge about the person. For instance, the a priori knowledge can include photos or videos of the person captured in real life.

  • Patent number: 8599780
    Abstract: A technique for expanding the range of coverage for a wireless local area network (WLAN) involves locating a wireless access point (WAP) away from an interworking unit (IWU) at the edges of the WLAN and a (typically) wired network. The WAP, when located away from the IWU, can be referred to as an untethered access point (UAP) because it communicates with the IWU on a wireless channel. Stations on the WLAN will be capable of communicating with the WAP, whether or not it is a UAP, via a known or convenient wireless protocol, such as Wi-Fi, and may or may not be capable of communicating with one another via a direct station-to-station protocol.

  • Patent number: 8432826
    Abstract: A method and apparatus to select the best channel of a wireless network for data communication at any given time, during normal operation of the network, is described. The network may be an IEEE standard 802.11 compliant network. Channel scanning may be performed in any station on the wireless network, such as an access point (AP) or a mobile station, or both. Channel scanning may be performed during data communication idle time, or simultaneously with data communication on the network. The technique can be implemented in a multiple-input multiple-output (MIMO) communication system, where the antenna or antennas used for channel scanning can be selected dynamically during operation, to optimize one or more performance characteristics.
