Indoor localization using distance to Wi-Fi access points only.

Finding position using FTM RTT distance measuring protocol supported by Android phones with respect to Wi-Fi access points (APs). NOT using signal strength (RSSI), "fingerprinting", "learning" or other methods that do not scale. All that is needed are the coordinates of the APs. In this latest example, the APs do not even support IEEE 802.11mc (which would get even more accurate results)! Also, the large box store environment (80 m x 120 m) is difficult because most measurements are not line-of-sight and are, as a result, dominated by refractive retardation.
