Institute of Technology had upgraded the campus network in September 2019. Within this, the update of the wireless LAN system was based on both the survey results from the campus and five issues for improvement identified from the 2014-2018 usage trend survey. Specifically, the five issues were as follows: (1) increase the number of access points (APs) in expectation of an increase in the average number of terminals, (2) install IEEE 802.11ax APs in consideration of the dense environment, (3) increase the speed of the wired LAN in preparation for increased traffic, (4) control traffic not directly related to lectures,and (5) select APs based on usage trends. In this upgrade, the number of APs increased by 30% from 368 to 470. This paper describes our new wireless LAN system in detail and utilization trends for FY 2019. The effectiveness of the improvements then is examined by comparing wireless LAN usages before and after the upgrade.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"9","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌デジタルプラクティス（TDP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":219012,"links":{}}
