RSS-Based DOA / DOD Estimation Using Bluetooth Signal and its Application for Indoor Tracking

This paper studies a tracking performance of the positioning technique using RSS-based direction of departure/arrival (DOD / DOA) estimation. The multiple DOD beacons are fabricated and deployed in a middle-sized meeting room, and Bluetooth signal was used so as that the commercially available smartphone can receive the beacon signals and estimates its location. The measurement results reveal that the RSS-based DOD beacons realize high accuracy in positioning even for the moving terminal node; the DOD estimation accuracy was 6.7°∼9.1°, and positioning accuracy was 0.65 m∼0.86 m at 50 percentile.
