Currently, the maximum transmission speed of mobile data communication services is limited to 64kbps. It is desired that higher transmission speed be supported in order to meet the requirement of mobile multimedia applications. For this reason, we have developed 384kbps-PHS experimental system, which can achieve maximum transmission speed of 384kbps by adopting 64kbps PHS data communication protocol (PIAFS) and multi-link protocol. This paper presents implementation of 382kbps-PHS experimental system and performance evaluation using FTP under various radio environments.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"40","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告モバイルコンピューティングとユビキタス通信（MBL）"}],"bibliographicPageStart":"33","bibliographicIssueDates":{"bibliographicIssueDate":"1999-10-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"80(1999-MBL-010)","bibliographicVolumeNumber":"1999"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
