Along with development of IoT (Internet of Things), the importance of indoor location-based services is increases. Therefore, researches on beacon, which is widely used for indoor positioning, have been actively implemented. Among them, location positioning using Beacon's RSSI (Received Signal Strength Indication), which heavily used, but it is less accurate because it relies on the distance based on the signal strength. In this paper, Beacon transmits RF signal and specific frequency sound wave. The smartphone receives the two signals and converts them into distance values through the Time Difference of Arrival (TDoA) method. We propose a position location system that uses calculated distance values for trilateration in a smartphone. It is possible high accuracy even in existing smart phones. |
