Propagation characteristic estimation device, propagation characteristic estimation method, and propagation characteristic estimation program

A propagation characteristic estimation device for estimating a propagation characteristic of radio waves between a transmitting station and a receiving station that perform wireless communication, the propagation characteristic estimation device comprising:

• a processor;
• and
• a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
• based on input information from an external source, extract position information regarding the transmitting station and the receiving station and a frequency of radio waves transmitted by the transmitting station;
• calculate a three-dimensional distance between the transmitting station and the receiving station and a free space loss of radio waves based on the position information and the frequency;
• perform processing for, with use of a two-dimensional image of a region that includes the transmitting station and the receiving station, extracting an edge of a structure that reflects radio waves in the two-dimensional image;
• generate input data for use in machine learning, based on the position information, the three-dimensional distance, the free space loss, and the edge;
• and
• perform machine learning to estimate a propagation characteristic of radio waves between the transmitting station and the receiving station with use of the input data generated by the generation unit.
