Propagation environment estimation method propagation environment estimation system and propagation environment estimation device

A propagation environment estimation system that estimates a propagation environment of a radio wave using a scale model, the propagation environment estimation system comprising:

• a 3D printer that creates a scale model;
• an element mounter that installs, in the scale model, a light source regarded as a transmission station of a radio wave and a light receiving element regarded as a receiver;
• and
• a controller that causes the light source to irradiate a measurement range in the scale model and causes the light receiving element to measure a light reception level, wherein
• the controller is configured to execute calibration treatment of converting data of the light reception level obtained by the measurement into a reception level of the radio wave, the calibration treatment including calibrating the data of the light reception level on a basis of an attenuation characteristic of the radio wave corresponding to a propagation distance in a target area.
