unavailable in indoor environment, Bluetooth Low Energy (BLE) based localization is studied. BLE localization utilizes RSS (Received Signal Strength) measured on three advertising channels whose frequency is separated by up to 78MHz without channel recognition, suffering from low localization. We have developed separate channel fingerprinting in our previous work to improve localization accuracy, which still suffers from large error. In this paper, we present 2-step separate channel fingerprinting that combines unified channel localization and separate channel localizaion. We conducted experimental evaluation and demonstrated that the 2-step separate channel fingerprinting successfully improved localization accuracy by approximately 22.7 % compared to separate channel localization.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告モバイルコンピューティングとパーベイシブシステム（MBL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-02-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2019-MBL-90"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T00:59:36.220627+00:00","id":194557,"links":{}}
