Abstract

See full text

An objective of the present invention is to use a calculation model to calculate, with good accuracy, behavior of electromagnetic waves within an actual service area. Provided is a radio environment evaluation method that includes constructing, within a computer resource, a structural model for an electromagnetic wave scatterer, and when calculating a characteristic of an electromagnetic field by using the structural model and a ray that simulates a radio wave traveling straight through real space, correcting, in accordance with electromagnetic wave vector measurement data for real space, a state of a polygon included in the structural model.
