Abstract: Methods, systems, computer-readable media, and apparatuses for obtaining a location fix for a mobile device are presented. In some embodiments, a method includes identifying a region in which the mobile device is located. The method further includes receiving assistance data pertaining to one or more access points within the region, wherein the assistance data is indicative of signal information pertaining to the one or more access points at multiple locations within the region. The method also includes generating, at the mobile device, a heatmap representative of multiple locations within the region as compared against the signal information pertaining to the one or more access points that are in communication range. The method additionally includes determining the location fix based at least in part on the generated heatmap.

Abstract: The present disclosure describes methods, systems, computer-readable media, and apparatuses for evaluating the suitability of AP signaling for RTT-based location calculation. Various evaluation methods are disclosed to enable the signaling to be tested for consistency and reliability. An AP may be analyzed by a mobile device or other communications mechanism to determine whether the AP is suitable for RTT-based location signaling. A mobile device receives multiple signals from an evaluated AP at various locations in the indoor area, and derives RTT data from the signals. The RTT data is analyzed to determine whether RTT data from the AP should be used by mobile devices in the process of calculating their location.
