未満に抑えられるため，推定精度は分類の際の閾値に比較的非依存であることを示す．一方，特に障害物が多い環境では BLE 信号は端末間の距離の大小関係を正しく認識できず，それに伴い位置推定誤差が 2～3m

estimates the locations of terminals by classifying the distance between terminals into two values, “close” and “far”, rather than the distance between terminals itself. Therefore, in applying this method, it is important to have a means for the binary classification of the distance between terminals as well as to determine a threshold value for the binary distance classification. In this paper, we experimentally verify the estimation accuracy of the proximity-based location estimation method when the binary classification is made by BLE signals. First, we show that if the distance between terminals can be accurately classified into “close” or “far” by the BLE signal, the location estimation error is less than 1 m. On the other hand, with the existence of many obstacles, the BLE signal cannot correctly classify the distance between terminals into “close” or “far”, resulting in the location estimation error of about 3 m.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2023-UBI-77"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:23:49.667728+00:00","id":224229,"links":{}}
