Abstract
A system for use in locating a sought device such as a smartphone or smart communication device. The system includes a sought device communicatively linked to a communications network. The sought device uses locating technologies to determine an approximate location of the sought device and operates to trigger a locating session and to transmit a message over the communications network including the approximate location. The system includes a seeker device communicatively linked to the communications network operable to receive a message over the communications network including the approximate location of the sought device. The sought device scans for broadcasts from the seeker device, and the seeker device broadcasts a wireless message. The sought device receives the wireless message, determines a signal strength, and transmits the signal strength to the seeker device. The seeker device processes the signal strength to generate an indicator of a location of the sought device.
