Abstract: A system in which a device may automatically provision another device with credentials, at the behest of a cloud-based service, based in part on the physical proximity of the device to be provisioned. The provisioning device and the device to be provisioned may use a radio access technology (RAT) with a limited radio range. Account information associated with the device to be provisioned is known to the cloud-based service, which authenticates the device to be provisioned via the device with credentials.

Abstract: Described are techniques for distributing audio data to multiple audio devices for generation of a synchronized audio output. A master device may receive audio data from a content server or other remote data source and store the audio data in a local cache. The master device may provide the audio data to multiple slave devices using a single multicast transmission. In some cases, the master device may also provide the audio data to individual slave devices unable to receive the multicast transmission using a network connection. Each slave device may store the audio data in a local cache. To generate the audio output, each audio device may retrieve the audio data from the associated local cache, which may enable the audio data to be distributed without modifying the commands used by audio applications to generate the audio output.

Abstract: Described are techniques for configuring a group of devices to distribute and receive data in a manner that reduces consumption of network resources. A larger group of devices may be divided into subsets of devices, each subset including a master device that provides data to multiple slave devices via a multicast transmission. A master device may be determined based on the respective signal quality between the audio devices and an access point, and the number of other audio devices to which each respective audio device may provide data. Other devices having respective signal quality for communication with the master device that exceeds a threshold may be designated as slave devices. Once a first subset is formed, the remaining devices may be grouped into additional subsets. Remaining devices that are not a part of any subset may receive data via communication with an access point.

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.

Abstract: Described are techniques for modifying the data rate used to transmit audio data from a master device to slave devices. After receiving a signal, each slave device requests transmission of one or more packets and reports an individual error rate. A cumulative error rate may also be determined based on the individual error rates and the retransmission requests. If any individual error rate or the cumulative error rate exceeds a maximum threshold, the data rate used to transmit the audio data is decreased. If an individual error rate is less than a minimum threshold, the data rate may be increased. If an error rate exceeds a critical threshold, the data rate may be reduced to a minimum value supported by the devices.

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. In this way, multiple chipsets that communicate using different standards at overlapping frequencies may avoid performance issues experienced in simultaneous use cases, while performing the communications which are of a highest priority level.

Abstract: Devices, systems and methods are disclosed for allowing a mobile device to connect to a network based on data rates. For example, the mobile device may select from available networks based on data rates associated with the available networks. In addition, the mobile device may determine to roam from a current network based on data rates. For example, the mobile device may roam when an expected throughput exceeds an actual throughput or when an anticipated throughput requirement exceeds the actual throughput.
