    摘要: A technique is offered which is adapted for optimization computations and which makes it possible to carry out an estimation of the state of propagation of radio waves quickly and accurately during a search for the locations of wireless stations. During the optimization computations, sending points and receiving points are set using a parameter search technique. Propagation paths are computed using a far-field approximation technique for Maxwell's equations. A propagation path leading to a local area where the accuracy is low with the far-field approximation technique is extracted from the computed paths. The state of scattering previously calculated using a numerical analysis technique for Maxwell's equations is reflected in the extracted path to modify the propagation path. The communication characteristics of the modified path are evaluated. The steps S101-S105 are performed repeatedly a given number of times. A sending point and a receiving point producing optimum communication characteristics are output.

    摘要: 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.
