Abstract: In various embodiments, crowd sourcing techniques are provided to enable RTT-based positioning of UE. To address issues of discovering which beacons (e.g., Wi-Fi APs, cellular base stations, BLE transmitters, etc.) support measurement of RTT (e.g., according to IEEE 802.11mc, 3GPP Release 16, etc.), beacon RTT capabilities may be crowd-sourced from UE and maintained by a cloud-based location platform in a beacon database (or more specifically, a RTT database portion thereof). To address the issue of determining physical antenna positions, RTT measurements may be crowd-sourced from UE for those beacons that are RTT capable, and used by a trilateration algorithm (e.g., a WLS multilateration algorithm) to determine physical antenna positions, which also may be maintained in the beacon database. Accuracy of the trilateration may be enhanced by obtaining raw GNSS measurements (e.g., psuedoranges) from the UE, and performing a cloud-based RTK GNSS position fix for the UE.

Abstract: Apparatus, methods, and computer program products for providing location to a device are provided. An example method may include receiving a location request associated with a device. The example method may further include determining a current raw location and a device history associated with the device. The example method may further include determining, based on the current raw location and the device history, at least one processing algorithm. The example method may further include determining an adjusted location based on the current raw location, the device history, and the at least one processing algorithm. The example method may further include transmitting, for the device, a location response including the adjusted location.
