Ratio under received power threshold is calculated by measuring the complex permittivity of a used desk and propagation loss characteristics along the surface of a desk plane. This calculation result shows Non LOS conditions existence even though line of sight is secured on the desk environment. Visibility estimation in the typical Japanese office is calculated using light emission method and shows high rate of Non LOS condition. In order to minimized Non LOS conditions, multi hop protocol is proposed. Terminal BER profile is used for finding to the most suitable extension point (EP). The use of twin link communications and an automatic handover mechanism, which are minimized to Non LOS condition, are proposed.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14990/00000075","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"甲南大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11561231","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13480383","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kuribayashi, Nobuhiko"}],"nameIdentifiers":[{"nameIdentifier":"318","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"岳, 五一","creatorNameLang":"ja"},{"creatorName":"ガク, ゴイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Yue, Wuyi","creatorNameLang":"en"}],"familyNames":[{"familyName":"岳","familyNameLang":"ja"},{"familyName":"ガク","familyNameLang":"ja-Kana"},{"familyName":"Yue","familyNameLang":"en"}],"givenNames":[{"givenName":"五一","givenNameLang":"ja"},{"givenName":"ゴイチ","givenNameLang":"ja-Kana"},{"givenName":"Wuyi","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"82","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50234175","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50234175"}]},{"creatorNames":[{"creatorName":"Kuribayashi, Nobuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"320","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-03-24"}],"displaytype":"detail","filename":"K00038.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"K00038","url":"https://konan-u.repo.nii.ac.jp/record/79/files/K00038.pdf"},"version_id":"90f32476-748b-4d85-8b4c-79f45481e3ed"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Millimeter wave band","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-hop protocol","subitem_subject_scheme":"Other"},{"subitem_subject":"Non LOS condition","subitem_subject_scheme":"Other"},{"subitem_subject":"propagation loss characteristics","subitem_subject_scheme":"Other"},{"subitem_subject":"Millimeter wave band","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-hop protocol","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Non LOS condition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"propagation loss characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Non LOS Conditions in Millimeter Wave Band and Proposed Multi-hop Protocol","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Non LOS Conditions in Millimeter Wave Band and Proposed Multi-hop Protocol"},{"subitem_title":"Non LOS Conditions in Millimeter Wave Band and Proposed Multi-hop Protocol","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"18","path":["33"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-24"},"publish_date":"2015-03-24","publish_status":"0","recid":"79","relation_version_is_last":true,"title":["Non LOS Conditions in Millimeter Wave Band and Proposed Multi-hop Protocol"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2025-02-27T05:09:02.309307+00:00"}
