Abstract
A system for tracking cargo containers contained within a terminal includes a tag transmitter adapted to be positioned on container handling equipment and operative for transmitting a wireless RF signal based on an event affecting the location of a container handled by the container handling equipment. A plurality of spaced apart access points are positioned at known locations within the terminal that receive the wireless RF signals from the tag transmitter. A processor is operatively connected to the locating access points for geolocating the tag transmitter and determining the container location at the time the event occurs.

A system for tracking cargo containers contained within a terminal comprising:
- a tag transmitter adapted to be positioned on container handling equipment and operative for transmitting a wireless RF signal based on an event affecting the location of a container handled by the container handling equipment;
- a plurality of spaced apart access points positioned at known locations within the terminal that receive the wireless RF signal from the tag transmitter;
- and
- a processor operatively connected to the locating access points for geolocating the tag transmitter and determining the container location at the time the event occurs.
A system for tracking cargo containers contained within a terminal comprising:
- an antenna mast adapted to be supported by container handling equipment;
- a tag transmitter supported by said antenna mast and operative for transmitting a wireless RF signal having data identifying the container handling equipment;
- a plurality of spaced apart access points positioned at known locations within the terminal that receive the wireless RF signal from the tag transmitter, wherein said tag transmitter is supported by the antenna mast at a height above the stack height of any containers permitting line of sight transmission of a wireless RF signal to any locating access points;
- and
- a processor operatively connected to the locating access points for geolocating the tag transmitter and determining the container location based on the location of the container handling equipment.
