Abstract: Embodiments are disclosed for compressing radio maps of fingerprint-based positioning systems using different compression models. In an embodiment, a method comprises: receiving, by a computing device, access point (AP) data from a plurality of mobile devices operating in a geographic region, the AP data including signal strength measurements of AP signals received at a plurality of reference locations in the geographic region and uncertainty measurements associated with the signal strength measurements; determining a level of accuracy with the first compression model; responsive to the determining, selecting one of the first compression model or a second compression model to compress the AP data, the second compression model being different than the first compression model; compressing the AP data using the selected compression model; and responsive to a request from a mobile device operating in the geographic region, sending a data packet including the compressed AP data to the mobile device.

Abstract: Embodiments described herein provide for an electronic device comprising a set of classifiers that can determine whether the electronic device is likely on an airplane. Upon a determination that the electronic device is likely on an airplane, one or more wireless radios on the electronic device (e.g., an ultra-wideband ranging radio, a cellular radio, etc.) may be disabled or a prompt can be displayed to enable a user to place the device into airplane mode.

Abstract: An example method includes obtaining a plurality of data items. Each data item includes an indication of a particular location, an indication that a wireless signal from a first access point was observed at that location, and an indication of a time at which the wireless signal from the first access point was observed at that location. The method also includes determining a locational stability of the first access point based on the data items. Determining the locational stability of the first access point includes clustering the plurality of data items into one or more clusters based on the locations indicated in the plurality of data items, determining whether the N most recent data items are associated with a common cluster, and determining whether a time span between the N most recent data items exceeds a threshold period of time.

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: In some embodiments, an electronic device displays visual indications to a user when an electronic device is associated with a particular user account. In some embodiments, an electronic device displays notifications of a separation with a remote locator object (and/or device). In some embodiments, an electronic device utilizes a first or second locator process for locating a device or a remote locator object based on the device or remote locator object being located. In some embodiments, an electronic device facilitates finding associated components that are at one or more physical locations. In some embodiments, an electronic device facilitates display of location information of associated components that are at one or more physical locations.

Abstract: Portable electronic devices can be used to perform tracking functionality through the exchange of proximity messages. Based on the payload in these messages, a mobile device can detect whether a portable electronic device is likely performing unwanted tracking. The mobile device user may wish to identify an account that is associated with the portable device. In response to a request from the mobile device, the portable electronic device can provide a partial identifier that can be used to determine an associated account. The portable electronic device can also provide information that the mobile device can use to locate disablement instructions that can show how to stop the portable device from performing tracking functionality.
