RttScan

Use WiFi Scans to determine properties of nearby Wi-Fi access points (APs), then estimate the distance to them using two-sided round-trip-time (RTT) if they support IEEE 802.11mc protocol, or,using one-sided RTT if they do not. Can be used to estimate the offset in RTT measurements in order to improve the accuracy of indoor localization with apps such as FTMRTT and WiFiLocator.
