Abstract

A computer system, which estimates a radio wave propagation characteristic in a space where a wireless communication system using structure data and system data is constructed, includes a computer having a processor and a storage apparatus and holds feature parameter information, which stores an entry that associates a parameter included in structure data, that is, a feature parameter which greatly contributes to an estimation result of the radio wave propagation characteristic in the space with a type of the space. When receiving a request for estimation of a radio wave propagation characteristic in a target space, the processor retrieves an entry associated with a type of the target space from the feature parameter information, and presents an interface to input a value of the feature parameter included in the retrieved entry as estimation structure data and an interface to input estimation system data.
