Position Estimation Method Using RSSI Measuring Sensors

For device-downsizing and easiness of adaptation, we estimate position by using radio signal strength indication (RSSI). But, indoor environment, position estimation by using RSSI is difficult through multipath fading. In our study, to solve this problem and take advantage the RF communication, we propose RSSI measurement sensor using RSSI which is based on 125kHz, which is less subject to multipath fading, and we conduct position estimation experiment by using this sensor.
