A method includes moving an interrogation device through multiple geographical positions. At each geographical position of the interrogation device, a wireless communication terminal is solicited to establish temporary communication with the interrogation device, and a distance value indicative of a distance between the wireless communication terminal and the interrogation device as well as a velocity of the interrogation device is estimated using the temporary communication. A geographical location of the wireless communication terminal is calculated based on multiple estimated distance values and velocities of the interrogation device corresponding to the respective multiple geographical positions of the interrogation device.
