Abstract (in Japanese) (See Japanese page) 
(in English) The authors have proposed a method for estimating the interference power and occupancy of other systems using chirp demodulation for the Long Range-Wide Area Network (LoRa-WAN), which is a low power wide area (LPWA) standard. In this paper, we investigated a method of adaptive channel switching based on the same channel interference power and occupancy estimation. The effect of expanding the channel utilization rate was clarified when the channel with the maximum expected channel utilization opportunity was selected based on the same channel interference power and occupancy rate estimation.
