Building upon the results of experiments evaluating the ranging performance of Wi-Fi RTT with APs deployed in a multi-floor environment, the focus is on estimating ranging results with large ranging errors based on the RSSI of ranging data. A calibration model is constructed to compensate for ranging results, and the ranging performance as well as positioning performance are evaluated accordingly. As a result, by compensating for ranging results based on RSSI, this study successfully avoids the degradation of ranging performance in a multi-floor environment, thereby achieving positioning at a level where hierarchical identification is feasible.}, title = {多階層環境におけるWi-Fi RTT Laterationによる測位性能向上の一検討}, year = {2024} }
