Abstract
A position-discovery method is provided for a mobile device equipped with non-wired short-range communication means for receiving locally-transmitted messages. At least some of the messages include position data concerning the originating point of the message. The device determines its position as being that of the most common originating point for messages in a set of most recently received messages.
