Abstract (in Japanese) (See Japanese page) 
(in English) The Low power wide area (LPWA) technology is employed as wireless internet access from remote Internet of Things (IoT) devices. The LPWA is superior to other radio interfaces in terms of both power consumption and radio coverage, and the multiple-input and multiple-output (MIMO) transmission is widely used in wideband and reliable radio connections. This article considers a radio relay configuration for the MIMO transmission to decrease the radio dead zone where it arises in a mountainous area. This article also discusses a compensation method for channel capacity degradation in MIMO transmission when it passes through a coupled channel of wireless-wired-wireless.
