PROBLEM TO BE SOLVED: To solve the problem that the conventional radiowave propagation simulator can not cope with the case for judging whether radiowaves reach each story of a building, and accurate simulation is impossible when a dense building group exists and reflected waves are considered. SOLUTION: This radiowave propagation simulator is equipped with a map data managing part for managing map data containing building information and altitude data, a two-dimensional map display for displaying map data two- dimensionally, an input for inputting coordinates of a simulation object region and a base station, a three-dimensional map forming part for forming a three- dimensional map from the data of the map data managing part, according to the input, a receiving level calculating part which obtains a radiowave propagation path between a transmitting point and a receiving point by using the three-dimensional map, and calculates the received level at a receiving point by using the path, and a three-dimensional map display for displaying the three- dimensional map. |
