PURPOSE: To provide the installation pattern decision method of a PHS base station capable of efficiently deciding the installation place of the base station in the case of considering both quality and costs and preparing the installation plan of the base station and the maintenance plan of the base station. CONSTITUTION: In this installation pattern decision method of the PHS base station, the plural different installation patterns of the PHS base station are prepared 1 for a prescribed service plan area and the simulation of electric field strength distribution is performed 3 for the respective installation patterns. The ratio of the area of a communicable area to the area of the service plan area is calculated 4 as a quality evaluation value on the basis of a simulated result for the respective installation patterns, a cost evaluation value is calculated 5 for the respective installation patterns and the installation pattern for the service plan area is decided from all the installation patterns on the quality evaluation values and the cost evaluation values for the respective installation patterns. |
