APは様々な通信規格のSTAにその存在を知らせるため、100msごとに低レートでビーコンを発信している。その結果、Airtimeが長いビーコン送信が、チャネルボンディングのように帯域幅を拡大するような高速化技術に対して、特に市街地などの稠密環境において悪影響となる可能性がある。本研究では、未使用APのビーコンによる他の無線LANへの通信性能の影響を調査する事前調査として、まず、2019年12月に実施された市街地における無線LANの普及／利用状況の調査結果を用いて、市街地における未使用APの調査を行う。","subitem_description_type":"Abstract"}]},"item_23_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2021年電子情報通信学会ソサイエティ大会,
