Preliminary Study on Indoor Localization using Smartphone-Based IEEE 802.11mc

Indoor localization using a smartphone-based technique is the next generation of indoor navigation and tracking, leveraging the IEEE 802.11mc WiFi-based fine time measurement (FTM) capabilities. The technique enables GPS-like operation indoor by using smartphone devices embedded with WiFi round trip time (RTT) enabled chipset. FTM allows timestamping of send and receive events at the hardware level which in turn allows calculation of very accurate RTT to estimate distance. The technique is independent of infrastructure and is capable of networking and communicating through the formation of device clusters. Our indoor localization algorithms provide a localization error of less than 1.5m in 95% of the cases in typical university campus environments.
