          <datacite:description descriptionType="Other">近年，無線 LAN 機能を備えた情報端末がますます増加している．それにより，多くの無線端末が同一の無線 LAN アクセスポイントへの接続が集中することによる，スループットの低下が懸念される．そこで，周波数の利用効率を高めるため，通信品質を担保しつつ多くの端末の同時通信を可能とする通信システムを検討した．まず，Wi-Fi 通信モジュールマイコン ESP32 に備わるチャネルスキャン機能を用いて無線端末が事前にチャネルの利用状況を短時間で把握し，最も利用されていないチャネルを選択する．さらに ESP32 を AP モード端末と STA モード端末に分け， AP モード端末が STA モード端末に命令し，複数の STA モード端末からのデータを収集する．収集したデータは転送専用チャネルで一括転送する．以上の通信システムを提案し，実測によりそのフィージビリティを確認した．</datacite:description>
          <datacite:description descriptionType="Other">In recent years, information terminals equipped with wireless LAN functions are increasing more and more. As a result, it is expected that many wireless terminals will have more opportunities to connect to the same wireless LAN access point, and there is a concern that the throughput will decrease. Therefore, to enable the simultaneous communication of many terminals while ensuring communication quality, we investigated improving the frequency utilization efﬁciency. First, using the channel scanning function provided in the Wi-Fi communication module microcomputer ESP32, the wireless terminal grasps the channel usage status a short time in advance and selects the least used channel. Furthermore, ESP32 is classiﬁed into AP mode terminal and STA mode terminal, and AP mode terminals command STA mode terminals and collect data from multiple STA mode terminals. Collected data is transferred in a batch through a dedicated transfer channel. We proposed the above communication system and conﬁrmed its feasibility by actual measurements.</datacite:description>
