摘要

This manuscript discusses a new indoor positioning method called a fingerprinting trilateration method or FTM using BLE beacons. The strength of BLE signals, referred to as received signal strength indicators or RSSI, decrease as they travel through space. FTM employs a list of fingerprints of RSSIs and performs trilateration between the three closest fingerprints to locate a receiver's current position. An experiment in positioning performance is conducted in comparison with a traditional method of fingerprinting and the result shows that FTM could locate the current position with a positioning error of 0.615 m while it is 1.162 m for fingerprinting using a Between-points condition.
