Abstract
There is described a system and method for locating, and optionally monitoring the status of, a mobile entity in a given area fitted with a radio beacon. In one embodiment, the system features a network of bi-directional radio beacons which transmit on the same frequency at random intervals. A method for processing and relaying unique message identifiers throughout the system is disclosed which allows the vicinity of the mobile entity to be determined from any beacon in the network.
