Claim 5:
6. A station installation design device comprising:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:, acquires point cloud data between a base station device and a terminal station device as a point cloud data group; calculates 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; scans a region specified by the radius at each position where the point cloud data group is acquired to detect the point cloud data, and extracts a non-line-of-sight region; calculates 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; estimates a received power based on the calculated ratio between the areas; and determines based on the received power whether or not there is a line of sight between the base station device and the terminal station device.
