Abstract (in Japanese) (See Japanese page) 
(in English) A versatile variable-range IoT communication system using the VHF-high band, Diversified-Range IoT (DR-IoT)is being considered as an enabling technology for digital self-managed radio networks to enable multiple disaster response organizations to efficiently collect, share, analyze information and make decisions when the existing communication infrastructure is Not available due to a large-scale disaster. In DR-IoT system, there is communication between multiple mobile Nodes and base stations, which enables information sharing, Node management, and overall understanding under disaster conditions. In this paper, we estimate the K-factor of Nakagami-Rice fading using the moment method on the outdoor measured data to clarify the fluctuation characteristics of received power and to consider the accuracy of the estimation.
