However, there is a danger that the spurious signal emitted other than this signal from the RFID interferes with the multi-channel main signal. In this research, guidelines such as tags and arrangement of readers when applying to retailing and disaster triage are derived by link design considering reflectance and diffraction by the spurious signal possessed by RFID in consideration of the interference distance of RFID Proposed. As a result of the experiment, we observed that the spurious signal does not receive further interference from this signal at -20 dB. By setting horizontal distance of minimum 0.9m on the ground and minimum 1.1m in space, we satisfied the DU ratio of 20 dB. Therefore, this study demonstrated the interference avoidance effect by this signal of RFID by the spurious signal.","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":"1","bibliographicVolumeNumber":"2019-MBL-90"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T00:59:35.996407+00:00","updated":"2025-01-19T23:26:29.456127+00:00"}
