Provided is a wireless environment estimation system that stores stationary structure data including structure data of a stationary structure in a wireless communication area, moving object data including structure data of a moving object in the wireless communication area, and observation region data related to an observation region of an electromagnetic field, uses the stationary structure data and the observation region data to generate a first electromagnetic field analysis model for analyzing an electromagnetic wave reflected by the stationary structure in the observation region, sets a primary wave source at a position of a wireless station, generates a secondary transmission point from an electromagnetic field that is obtained by calculation using the first electromagnetic field analysis model and that reaches the observation region, uses the moving object data and the observation region data to generate a second electromagnetic field analysis model for analyzing an electromagnetic wave emitted from the secondary transmission point, and uses the second electromagnetic field analysis model to calculate an electromagnetic field caused by an electromagnetic wave emitted in a direction opposite to that of an electromagnetic wave reaching the secondary transmission point.
