However, in order to deploy the IEEE 802.11ax in a real campus, we should clarify both the effective usage of the channel bonding considering the total throughput and the throughput performance with coexisting of IEEE 802.11n/ac STAs (Stations). Therefore, in this study, we measured the throughput performance of IEEE 802.11ax with a different channel bonding and coexisting of IEEE 802.11n/ac by using iperf3 and multiple STAs. From measurement results, we derive the effective operation guideline of IEEE 802.11ax on campus wireless LANs.","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":"2021-05-06","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2021-IOT-53"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:12:14.161323+00:00","id":211041,"links":{}}
