1. A station installation design method comprising: a point cloud data acquisition step of acquiring point cloud data between a base station device and a terminal station device as a point cloud data group; a Fresnel zone radius calculation step of calculating a radius of a first Fresnel zone defined by the base station device and the terminal station device at each position where the point cloud data group is acquired; a non-line-of-sight region extraction step of scanning a region specified by the radius at each position where the point cloud data group is acquired to detect the point cloud data, and extracting a non-line-of-sight region; an area ratio calculation step of calculating a ratio of a total area of all the extracted non-line-of-sight regions to an area of a region constructed by the first Fresnel zone; a received power estimation step of estimating a received power based on the calculated ratio between the areas; and a line-of-sight determination step of determining based on the received power whether or not there is a line of sight between the base station device and the terminal station device.
