年に最初の無線 LAN 規格 IEEE 802.11 が策定されて以来，伝送レートを高速化するために数年ごとに新しい規格が登場し，現在では第 6 世代と言われる IEEE 802.11ax の標準化が完了している．標準化は後方互換性を維持しながら進んだため，最新規格 IEEE 802.11ax の AP (Access Point) でも IEEE 802.11a/b 対応機材は接続し通信を行うことができる．この後方互換性と比較的短い年月での世代更新により，キャンパス無線 LAN では多様な IEEE 802.11 規格が混在している．しかし，異なる規格の混在はスループット特性が低下する Performance Anomaly 問題の発生を招くため，可能な限り規格の混在を回避する運用が望ましい．そのためにはまず全接続に対する無線 LAN 規格の混在状況を把握する必要がある．そこで本稿では九州工業大学のキャンパス無線 LAN を利用する端末の規格を調査し，得られた知見から混在を回避するための運用方法を述べる．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Since the first wireless LAN standard, IEEE 802.11, was established in 1997, all standards provide backward compatibility, so the APs (Access Points) of the latest IEEE 802.11ax can be connected from legacy IEEE 802.11a/b terminals. However, using the different transmission rates in the same APs causes the performance anomaly that degrades the throughput performance drastically. In order to provide the stable operation for campus wireless LAN, it is vital to classify the wifi connection according to the IEEE 802.11 standards as much as possible. In this paper, we analyze the variety of the wireless LAN standards and examine how to avoid or mitigate the sharing the same AP with the different standards.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-07-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2021-IOT-54"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T17:39:36.829905+00:00","created":"2025-01-19T01:12:57.876750+00:00","links":{}}
