WifiRttScanX

WifiRttScanX is an app for ranging to Wi-Fi access points (APs)

WifiRttScanX determines the distance to Wi-Fi access points (APs). It can do this for APs that support the IEEE 802.11mc FTM RTT protocol and those that do not (i.e. are not cooperative)..

WifiRttScanX makes it easy to measure the bias or offset of distance measurement required for indoor navigation, such as when using the FTMRTT app.

WifiRttScanX can record Wi-Fi scans and ranging information and share these files later.
