Radio wave propagation characteristic estimating system, its method, and program

摘要

The amount of operation processing is reduced without largely degrading an estimation precision of radio wave propagation estimation. The radio wave propagation characteristic estimating system for estimating a radio wave propagation characteristic by taking into decision-theoretical consideration such a structure as a building or indoor furnishings includes the object selecting unit for selecting, from objects within a region to be analyzed, an object whose effect on an estimation precision is small by using position data of a transmission point, the number of constituent faces reducing unit for reducing the number of constituent faces of the selected object, and the radio wave propagation estimating unit for estimating radio wave propagation by using an object within the region to be analyzed which is not selected by the object selecting unit and an object whose number of constituent faces is reduced by the number of constituent faces reducing unit.
