Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As another example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

Abstract: A first wireless communication device (UE device) associated with a certain user (or included in a specified set/group of UE devices) may establish a first communication link with an accessory device according to a short-range radio access technology, and transmit link (pairing) information associated with the first communication link to a server, such as a cloud-based server. The server may share this (first) link information with other UE devices associated with the same user (or belonging to the same specified group of UE devices as the first UE device). Link information associated with the other UE devices (i.e. second link information) may equally be shared with the accessory device, and the other UE devices and accessory device may use the first link information and second link information in establishing respective communication links between any of the other UE devices and the accessory device without having to undergo a pairing procedure.

Abstract: Embodiments described herein provide for a non-transitory machine-readable medium storing instructions to cause one or more processor to perform operations comprising establishing a wireless connection with a beacon peripheral, monitoring a connection state of the wireless connection, in response to detecting a loss of connection with the beacon peripheral, posting a separation notification for the beacon peripheral to a notification framework of the electronic device, deferring display of the notification during a reconnect interval, attempting to reconnect with the beacon peripheral during the reconnect interval, and displaying the separation notification via a user interface in response to a failure to reconnect with the beacon peripheral.

Abstract: This application relates to electronic devices configured to connect to a wireless local area network and communicate using a trigger-based access mechanism. An access point is configured to manage the wireless local area network. The access point includes a processing subsystem configured to select a channel associated with a communications medium for communicating with the set of electronic devices. The processing subsystem is also configured to monitor the channel to detect interference from radio frequency sources not connected to the wireless local area network, receive channel information for at least one additional channel associated with the communications medium from the electronic devices, and configure an interface circuit of the access point to communicate with the set of electronic devices on a new channel based, at least in part, on the channel information. Each electronic device can be configured to collect the channel information and transmit the channel information to the access point for analysis.

Abstract: Methods, systems, and apparatuses are presented to utilize Bluetooth (BT) radios to synchronize ultra wideband (UWB) radios, to allow the UWB radios to operate within narrow transmit/receive windows, which may lead to power savings. In some implementations, a transmitting UWB radio and a receiving UWB radio may synchronize the expected time of an UWB transmission based on BT events, such as receiving a BT advertisement, or establishing a BT connection. In some implementations, the transmitting UWB radio and the receiving UWB radio may synchronize the expected time of an UWB transmission based on synchronized event counters maintained by the BT radios. Information regarding UWB transmission start times may also be passed via BT communications, in some implementations.

Abstract: Embodiments of the current disclosure facilitate the creation of a wireless connection between a host device and an accessory device over a wireless medium. For instance, according to some embodiments, a method of connecting an accessory device to a host device includes transmitting a plurality of advertising beacons over a wireless medium. Each wireless beacon can contain information identifying a predetermined time when the accessory device will begin a page scan. The accessory device can begin the page scan at the predetermined time and can receive pages from a host device during a page scan window of the page scan over the wireless medium. The received pages can then be subsequently used to establish an ad hoc network connection between the accessory device and the host device.

Abstract: The presence of a wireless device and/or accessory that cannot maintain an independent network connection can be detected by network connected wireless devices and the location of the detected device and/or accessory can be reported to a device location service. As the wireless devices and/or accessories do not have independent network connections, periodic maintenance is performed on those devices by nearby owner devices to which the wireless devices and/or accessories are paired or associated. Described herein are systems, methods, and associated devices to maintain a locatable wireless device by a set of multiple owner devices for that wireless device.

Abstract: Disclosed herein are system, method, and computer program product embodiments for synchronizing the switching of different wireless platforms to different portions of a frequency band. An embodiment, at a first wireless platform, operates by receiving a band switch request message from a second wireless platform, wherein the band switch request message comprises a band switch delay period for the second wireless platform. The embodiment calculates a band switch time based on a band switch delay period for the first wireless platform and the band switch delay period for the second wireless platform. The embodiment transmits a band switch accept message comprising the band switch time to the second wireless platform. The embodiment sets a first filter to operate on a second portion of the frequency band based on the band switch time. The embodiment then operates on the second portion of the frequency band.

Abstract: Methods for aggregating Bluetooth profiles for faster connection and configuration are disclosed, including transmitting, subsequent to establishing a connection, a request message to a peer device that indicates support of a fast connection protocol for Bluetooth profiles configuration and receiving a response message from the peer device that indicates the peer device supports the fast connection protocol. After pairing with the peer device, a first list of profile descriptors for a plurality of Bluetooth profiles supported by the device may be transmitted to the peer device and a second list of profile descriptors for a plurality of Bluetooth profiles supported by the peer device may be received. A configuration of a plurality of Bluetooth profiles base, at least in part, on a comparison of the first list of profile descriptors to the second list of profile descriptors may be determined and transmitted to the peer device.
