Abstract
A position identifying device calculates a plurality of estimated lines with base points at the monitoring devices and with radii equal to estimated distances from the monitoring devices to the wireless communication device, based on a transmission signal of a wireless communication device in a target area acquired from each of monitoring devices disposed around the target area, and, when first intersections of a standard estimated line with a base point at a standard monitoring device, and reference estimated lines with base points at reference monitoring devices, are located farther from the standard monitoring device than a virtual standard line connecting two of the reference monitoring devices, identifies, as a position of the wireless communication device, an inside of a first area inside the first intersections and second intersections of the virtual standard line and the reference estimated lines.
