Abstract
A method for searching for a lost asset equipped with a short-range wireless transceiver includes a finder service sending out a search request including a lost-asset identifier, this request being sent over a mobile radio infrastructure to a plurality of mobile devices. These devices transmit on the request in their immediate vicinity using short-range wireless transceivers. Upon a mobile device receiving back a response from the lost asset, it returns a found message over the mobile radio infrastructure to the finder service. This message includes location data concerning the whereabouts of the lost asset or the message enables such data to be obtained by the finder service.
