Abstract
A radio wave propagation characteristic estimation apparatus includes at least a ray launching method calculation unit, an imaging method calculation unit, and a synthesis unit. The ray launching method calculation unit calculates a first piece of radio wave propagation characteristic estimation data in which a radio wave propagation characteristic from a radio wave transmission point to a building with a radio wave reception point is estimated, using a plan view data. The imaging method calculation unit calculates 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. The synthesis unit calculates pieces of indoor penetration data to the radio wave reception point within the building respectively for the first piece and the second piece, and synthesizes the pieces of indoor penetration data.
