著者：Eisuke Hanada題名：病院建築における無線通信基盤環境の向上に向けた提言発表情報：2021年新興通信技術に関する国際会議 ページ: 23キーワード：病院建築、ICT、無線通信、LAN概要：政府の調査によると、日本の病院の約90％は無線LANを導入しており、約80％の病院が医用テレメータを導入している。近年のCOVID-19の影響もあり、その他の無線通信の利用も拡大している。しかし、約半数の病院では通信障害などが発生している。その主な原因は、特定のエリアで電波が届かないことである。無線LANについては、アンケートの結果、「繋がらない、繋がりにくい」という回答が最も多かった。無線LANの転送速度は、端末が受信する電波の強さによって変化するため、接続しにくい原因の一つとして、弱い（減衰した）電波しか端末に届かないことが挙げられる。病院内の信号伝搬には様々な問題があるが、その多くは、設計段階で病院の建物部品の電波特性が十分に考慮されず、アンテナ配置への配慮不足に起因すると考えられる。そこで本発表では、大規模病院に無線通信インフラを設置する際に考慮すべき工事手順を説明し、情報通信施設の運用における問題点の解決策を検討する。抄録：According to a survey by the Japanese government, about 90% of hospitals in Japan have a wireless LAN and about 80% of hospitals have a wireless medical telemetry system. Due to the recent COVID-19 pandemic, the use of other types of wireless communication is also expanding. However, about half of the hospitals have experienced communication failures and other disruptions. The main cause is a lack of signal in certain areas. For wireless LANs, the most common response to a survey was "No connection or difficulty connecting to the wireless LAN”. The transfer rate of wireless LANs varies according to the strength of the signal received by the terminal, one of the causes of difficulty in connecting is that a weak (attenuated) signal is reaching the terminal. There are many problems in signal propagation in hospitals. We think that most of them are due to where the antennas are positioned when the radio characteristics of the hospital building components are not carefully taken into consideration in the design phase. In this presentation, we will discuss the construction procedures that should be considered for setting up a wireless communication infrastructure in a large hospital and consider solutions to problems in the operation of information and communication facilities.英語フィールド
