低電力・広域ネットワークLoRaWANを利用した地域問題の解決

―群馬県太田市におけるエリア拡充と熱中症アラートへの適用事例紹介―

抄録

In this study, we verified the communication coverage area by installing LoRaWAN gateways in Ota City, Gunma Prefecture. We confirmed that the LoRaWAN gateways (antenna base stations) installed in elementary schools in Ota City have good signal conditions. In addition, by installing LoRaWAN-compatible temperature and humidity sensors in the gymnasiums of elementary and junior high schools, we constructed a system that enables stable measurement. The discomfort index was calculated and made available to each elementary and junior high school, and the system was also constructed so that the Ota City Board of Education could view and manage it all together.
