Abstract
An information processing system includes: an acquisition unit configured to divide a target area into a plurality of meshes of a predetermined size, and acquire mesh data indicating the environment of the target area with height information about the plurality of meshes on a per-mesh basis; a first ray tracing unit configured to determine a two-dimensional ray trace from a transmission point to a reception point on the basis of the mesh data, a radio wave being transmitted at the transmission point, the radio wave being received at the reception point; a second ray tracing unit configured to determine a three-dimensional ray trace corresponding to the two-dimensional ray trace, on the basis of the mesh data, and height information about the transmission point and the reception point; and a radio field intensity calculation unit configured to calculate an intensity of the radio wave at the reception point, using one or more three-dimensional ray traces determined by the second ray tracing unit.
