  • Patent number: 10027592
    Abstract: A group of computing devices use a wireless channel for communication, resulting in congestion. Within that group, some devices may need to exchange time sensitive application data, such as data indicative of control inputs received from a user. A destination device may transmit a clear to send (CTS) frame over the channel that indicates a CTS interval indicative of a time to suspend transmission. Other computing devices respond to the CTS frame by suspending transmission for the specified CTS interval. However, a source device in the group of many computing devices receives the CTS frame and initiates transmission of application data instead of suspending transmission. As a result, the source device transmits while other computing devices are not transmitting. In some implementations a beacon frame may be transmitted before a CTS frame. The destination device may confirm receipt of the application data by transmitting an acknowledgement to the source device.

  • Patent number: 9998294
    Abstract: Described are techniques for configuring a group of audio devices to provide a synchronized audio output. Values indicative of the data throughput for communication between each audio device and the access point and between the audio devices themselves may be determined. A value indicative of the airtime that would be used to communicate data to other audio devices, via a multicast transmission, may be determined for at least a portion of the audio devices. Based on the airtime values, the audio devices may be divided into subsets, each including a master device configured to provide data to one or more slave devices via a multicast transmission. A global master device that receives audio data from a data source and provides the data to the other master devices may be selected based on the data throughput values for communication between each master device and the access point.

  • Patent number: 9929753
    Abstract: Techniques for harmonizing wireless communications performed by a computing device which communicates using varying wireless communication standards are described herein. For instance, a computing device may include multiple chipsets with associated antennas that are configured to perform wireless communications using separate wireless standards which operate at overlapping frequencies. To avoid performance degradation experienced in simultaneous use cases with communications operating at overlapping frequencies, the multiple chipsets may be configured with logic to determine which communications are prioritized when multiple chipsets attempt to communicate simultaneously. The multiple chipsets may be communicatively coupled to coordinate their communications by prioritizing certain types of communications over other types of communications to avoid simultaneous communications in overlapping frequencies.

  • Patent number: 9924438
    Abstract: Devices, systems and methods are disclosed for allowing a mobile device to roam from a first frequency band to a second frequency band for a dual band access point when a signal strength associated with the first frequency band improves. For example, the mobile device may store a first signal strength associated with the first frequency band when the mobile device first connects to the first frequency band and may monitor subsequent signal strengths to determine if they exceed the first signal strength. When a subsequent signal strength exceeds the first signal strength, the mobile device may use this as an indication that the mobile device is closer to the access point and within range of the second frequency band. The mobile device may then detect and connect to the second frequency band.

  • Patent number: 9894604
    Abstract: Approaches enable a device capable of wireless communication, such as a device having a wireless adapter, to automatically select and connect to an available wireless access point (AP) having favorable performance, security, and/or other attributes that may be ascertained through various parameters, despite the wireless AP not being the last-known and/or last-connected-to wireless AP. The wireless-enabled device may determine the wireless AP to connect to in a number of ways, such as by determining all available wireless APs in the vicinity of the device and identifying, ranking and/or scoring the parameters for some or all of the available wireless APs to determine a ranking of the wireless APs. Once a favorable wireless AP is identified, the device may automatically attempt to connect to the wireless AP. If the wireless AP is not available, the device may automatically attempt to connect to the next wireless AP in the ranked list, etc.

  • Patent number: 9819901
    Abstract: Devices, systems and methods are disclosed for enabling a device to act as a wireless extender and adaptively control a transmission power for capability messages. For example, when the device has the capability to relay traffic without affecting a local processing of the device, the device may transmit capability messages at a normal transmission power and may relay traffic between a network device and clients. However, when the device no longer has the capability to relay traffic without affecting the local processing, the device may transmit capability messages at a reduced transmission power. As clients use the capability messages to determine a signal strength of an access point, the reduced transmission power results in the device appearing to have a lower signal strength and thus decreases a desirability of the device as an access point.

  • Patent number: 9775069
    Abstract: Described are techniques for configuring a group of audio devices in communication with one another to provide an audio output. Test data may be communicated between a selected audio device and each audio device in the group to determine data throughput values for each communication. A value indicative of the airtime that would be used to communicate data to each audio device, using the selected audio device, may be determined. This process may be repeated for each audio device within the group. The selected audio device associated with the lowest airtime value may be designated as a master audio device. A maximum airtime value associated with distribution of audio data from the master audio device to the other devices may be determined based on the data throughput values for each device. If the maximum airtime value is less than a threshold airtime value, the audio data may be distributed.
