Experiment of indoor position presumption based on RSSI of Bluetooth LE beacon

Real-time indoor location estimation needs multiple signals from different sources. To ensure accuracy of estimation, adopting Bluetooth Low Energy (LE) beacon devices as signal sources is a reasonable solution. We have installed a number of Bluetooth Low Energy (LE) beacon devices in and around a room and observed beacons by portable devices with RSSI to achieve fundamental knowledge of beacons and feasibility of location estimation. By applying an estimation method, we have achieved over 95% of correct estimation rate and complete separation that a device is in a room or not.
