Abstract
A relay device has the following configuration for quickly and easily acquiring highly accurate terminal position information and controlling the reconfigurable intelligent surface. The reconfigurable intelligent surface dynamically changes the reflection direction of the radio wave. The image sensor captures a use range of a terminal composed of a plurality of regions divided in a lattice shape. A control device controls the reconfigurable intelligent surface. In particular, the control device acquires image data of a use range of the terminal captured by the image sensor. The control device searches for a region where the terminal exists among the plurality of regions from the image data. The control device directs the reflection direction of the reconfigurable intelligent surface to a region where the terminal exists.
