Abstract: An address of each of three or more distance measurement devices, to which a communication packet of a target device is to be transmitted, is acquired. The distance between the target device and a distance measurement device is calculated, for each of the three or more distance measurement devices, based on a communication packet that the target device transmitted to the address of the distance measurement device. A location result for predicting a located position of the target device is generated based on positions of the three or more distance measurement devices and distances between the target device and the three or more distance measurement devices.
