Abstract: In the construction of a wireless network in a building, structure conditions such as the floor plan of the building and the shape of the floor, material conditions such as materials for structures, and the like have a great effect on radio wave propagation characteristics. This causes a problem that unless these pieces of information are taken into consideration, an accurate layout design of wireless base stations cannot be made. In the construction of a new wireless network in a building, a wireless network similar to structure conditions of a newly constructed building is extracted from structure conditions of past buildings in which a wireless network is constructed. The layout positions of wireless base stations used in the extracted wireless network are regarded as the layout positions of wireless base stations in the new wireless network.
