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.

Abstract: Techniques are provided for utilizing one or more mobile devices to estimate distances between wireless access points (APs). Embodiments can, for example, enable mobile devices, wireless APs, and/or other systems to estimate a distance between two wireless APs using Round-Trip Time (RTT) measurements obtained by one or more mobile devices. The RTT measurements can be utilized based on whether one or more related Received Signal Strength Indication (RSSI) measurements exceed a threshold value. Embodiments can also utilize crowdsourcing to obtain distance estimation data (e.g., distance estimates, RTT and/or RSSI measurements, etc.) from one or more mobile devices and/or propagate a determined distance, based on the distance estimation data, to multiple devices.
