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.
