Radio wave propagation characteristic estimation apparatus and computer program

A computer program which causes a computer to execute:

• an estimation process which estimates a characteristic related to propagation of a radio wave from one radio wave transmission point to one radio wave reception point in a specified zone;
• a reading process which reads information on buildings in the specified zone from a building database which has information on shapes, heights, orientations, and locations of buildings;
• a plan view data generation process which generates plan view data on the buildings in the specified zone, using the information on the buildings in the specified zone;
• a vertical cross-sectional view data generation process which generates vertical cross-sectional view data being data on cross-sections of the buildings in the specified zone taken along a vertical plane comprising a line that connects the radio wave transmission point with the radio wave reception point, using the information on the buildings in the specified zone;
• a ray launching method calculation process which calculates by a ray launching method a first piece of radio wave propagation characteristic estimation data in which a radio wave propagation characteristic from the radio wave transmission point to a building with the radio wave reception point is estimated, using the plan view data;
• an imaging method calculation process which calculates by an imaging method a second piece of radio wave propagation characteristic estimation data in which a radio wave propagation characteristic from the radio wave transmission point to the building with the radio wave reception point is estimated, using the vertical cross-sectional view data;
• and
• a synthesis process which calculates pieces of indoor penetration data to the radio wave reception point within the building respectively for the first piece of radio wave propagation characteristic estimation data and the second piece of radio wave propagation characteristic estimation data, and synthesizes the pieces of indoor penetration data.
