Object Localization Using RF Based IEEE 802.11 Frame Transceiving with FER Based RSSI Controlled Calibration

This thesis presents an approach of integrating single board computers as an access point and as a short-range object localization system. This is achieved by using open hardware and implementing IEEE 802.11 a/g/p based transceiving on low-cost Adlam Pluto Software Defined Radio (SDR), which operates in the S-band frequency range with Frame Error Rate (FER) controlled calibration. Experiments are conducted to investigate the effect of FER on the Received Signal Strength Indicator (RSSI) of IEEE 802.11 a/g/p transceiving, there by drawing the connection between the RSSI and the FER. Object localization is done based on the referenced RSSI and the real-time RSSI with FER based controlled calibration of RSSI. About 80% of accuracy can be expected from the implemented object localization system.
