Solving Regional Issuess Using the Low-Power, Wide-Area Network LoRaWAN

- Expansion of communication area in Ota City, Gunma Prefecture, and introduction of a case study of application to heat stroke alerts -

Abstract

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.
