Abstract: Systems, apparatus, and methods according to one or more embodiments are provided for encoding assistance data in locations technologies. In an embodiment, a method includes reading, by a processor, tile data of a database in a specific order, wherein the tile data comprises one or more reference data points and/or one or more empty spaces. The method also includes compressing, by the processor, the tile data based on the specific order using encoding. And the method further includes generating relative positions for each individual reference data point with respect to each other in the compressed tile data without specific location identification information for each reference data point.

Abstract: A distributed architecture provides the location of wireless transmitters to mobile devices for positioning, the location determined from at least one of crowdsourcing and wardriving. A server receives location data for wireless transmitters, such as an access point, a femtocell, Bluetooth Transmitter, radio-frequency identification (RFID) and near-field communication (NFC) station etc., from mobile devices. The server determines the locations of the wireless transmitters using the location data and provides the locations to the respective wireless transmitters. The wireless transmitters broadcast their identities and locations. Thus, a mobile device may receive the location directly from the wireless transmitter, eliminating the requirement of contacting a central server and downloading a regional almanac for positioning. This eliminates in a large number of scenarios the need to have data connectivity at the time of position calculation. Additionally, the wireless transmitters may transmit validation data to the server to validate or invalidate the determined location.
Abstract translation: 分布式架构提供无线发射机到移动设备的位置，用于定位，从至少一个众包和守卫确定位置。 服务器从移动设备接收诸如接入点，毫微微蜂窝，蓝牙发射机，射频识别（RFID）和近场通信（NFC）站等）的无线发射机的位置数据。 服务器使用位置数据确定无线发射机的位置，并向相应的无线发射机提供位置。 无线发射机广播其身份和位置。 因此，移动设备可以直接从无线发射机接收位置，消除了与中央服务器联系并下载用于定位的区域历书的要求。 这在大量情况下消除了在位置计算时具有数据连接性的需要。 此外，无线发射机可以向服务器发送验证数据以验证或使确定的位置无效。

Abstract: Techniques are provided for utilizing wireless devices for contact tracing, and more specifically for detecting a barrier between devices to enhance contact tracing applications. An example method for detecting a barrier between a first device and a second device includes determining, by the first device, a first range measurement with respect to the second device using a first positioning technique determining, by the first device, a second range measurement with respect to the second device using a second positioning technique that is different from the first positioning technique, and detecting the barrier between the first device and the second device based on the first range measurement and the second range measurement.

Abstract: Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by an emergency call server an indication of an emergency condition at a device, determining whether the device is to be tracked based, at least in part, on the indication of the emergency condition, and transmitting a triggering message from the emergency call server, in response to a determination that the device is to be tracked, to trigger at the device a tracking session to cause the device to periodically collect and send tracking session data to one or more servers. The tracking session, established between the device and the one or more servers, is separate from an emergency call session established between the device and the emergency call server.
