Abstract (in Japanese) (See Japanese page) 
(in English) Wireless communication is expected to improve the flexibility of equipment layout or of the factory IoT. A simple predicting system of the wireless environment is required for high quality wireless communication. The authors have acquired environmental information using LPWA and IoT sensors, analyzed the fluctuation correlation between the wireless environment and the physical environment using machine learning, and controlled transmission using the created learning model. It was shown that the error can be reduced by 95.5%. In this paper, we analyzed the dynamic environment in the factory by ray tracing and tried to consider the relationship between learning results and propagation environment changes.
