1. A station placement design method comprising:
extracting candidates for an installation location of a wireless base station from point group data in accordance with designated conditions for an installation location of a wireless base station;
determining presence/absence of visibility between a plurality of designated wireless terminal stations and the candidates for an installation location of a wireless base station based on the point group data and generating a first list including information in which the candidates for an installation location of a wireless base station and wireless terminal stations determined to have presence of visibility for the candidates for an installation location of a wireless base station are associated with each other;
generating a second list including information representing combinations of the candidates for an installation location of a wireless base station that enable all of the plurality of designated wireless terminal stations to be accommodated based on the first list;
sorting the second list in order from the smallest number of the candidates for an installation location of a wireless base station to the largest;
estimating a transmission speed of a case where a communication system that is able to perform communication in a case where the visibility is absent for wireless terminal stations determined to have absence of visibility for the candidates for an installation location of a wireless base station is used; and
generating a third list including information in which the wireless terminal stations determined to have absence of visibility for which the estimated transmission speed is equal to or higher than a predetermined value and the candidates for an installation location of a wireless base station are associated with each other.
