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.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告高度交通システムとスマートコミュニティ（ITS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-02-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2024-ITS-96"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":232670,"links":{}}
