WifiRttLocator App

The WifiRttLocator app can estimate a smartphone’s position to an accuracy of 1-2 meters. It requires the use of a Wi-Fi Access Point infrastructure that supports the IEEE 802.11mc protocol. At present this is not very common, but we expect it will be in the future. Google WiFi already supports this protocol, and can be used in combination with the WifiRttLocator, and is especially useful indoors where GPS is not available.

The application is designed as a demonstration and testing tool for developers, vendors, and universities, and can be used to validate the effectiveness of the Android Wi-Fi RTT API for positioning, navigation and retail applications. WifiRttLocator requires knowledge of the Access Point locations and operating parameters, which are read through a configuration file (.csv), and a floor plan file (.png). A full description of the application and the associated configuration file is provided in the user guide.
