This paper describes a verification experiment on the communication coverage area of the low-power, wide-area network LoRaWAN in Ota City, Gunma Prefecture, Japan. The relationship between the topography and the communication coverage area was verified. As a result of the measurement, the relationship between RSSI and distance, and between SNR and distance were clarified. The case studies of LoRaWAN applications are introduced: the measurement of temperature and humidity, and the measurement of the amount of garbage.
