ABSTRACT:
A passenger location system comprises a plurality of radio transceivers at predetermined locations in a passenger terminal facility. At least one transponder is associated in use with a passenger. The transponder is adapted to transmit a radio signal in response to receiving a signal from one or more of the transceivers. The transponder signal is capable of being received by more that one transceiver. The passenger location means is adapted to determine the position of the transponder by determining the location of the one or more transceiver that have received the transponder signal.
