This frequency band is suitable for mobile platforms. And, it can be easily expected that many users will desire the new type of information services (IS), which has 1.broadband, 2.mobility, 3.asymmetric, and 4.multicast features, near future. In order to effectively provide these IS, this paper proposes the novel mobile information platforms using both digital communication systems and digital TV broadcasting systems, where the digital TV broadcasting radio will be utilized as the broadband download links. The UHF band broadcasting radio will be expected high mobility in the proposed mobile IS platforms. In order to construct the proposed mobile platforms, it is necessary to investigate the radio propagation characteristics in UHF band. This paper also describes the UHF band radio propagation characteristics based on our measurement results using the existent TV broadcasting wave and GPS, and shows that the approximation of the received level can be evaluated using the terrain LOS area.","subitem_description_type":"Abstract"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_3_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110002664535","subitem_relation_type_select":"NAID"}}]},"item_3_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"情報処理学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ipsj.or.jp/","subitem_relation_type_select":"URI"}}]},"item_3_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意：本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
