Abstract
This disclosure provides methods and systems for locating wireless mobile devices in an area, for example, using an unmanned aerial vehicle. An unmanned aerial vehicle may receive a wireless signal with identification information from a mobile device. The unmanned aerial vehicle may fly in wireless communication range with the mobile device; measuring, representative parameters related to the received wireless signal and associating the value of measured representative parameters with the mobile device identification and with the location of the unmanned aerial vehicle at the time the wireless signal was received and estimating, the location of the mobile device in the area based on the value of measured representative parameters and the location of the unmanned aerial vehicle at the time it received the wireless signal. The measurement of the representative parameters may be time-stamped and the location of the unmanned aerial vehicle at the time the wireless signal was received may be calculated based on the time stamp and flight information of the unmanned aerial vehicle.
