Train Communication via Multiple Wireless Communication Links

Abstract:

A method of communication between first and second controllers positioned in spaced relation along a length of a train includes forming between the first and second controllers, first and second wireless communication channels operating at different carrier frequencies and causing the first and second wireless communication channels to be in communication in parallel, whereupon the first and second controllers are in communication via both the first and second wireless communication channels. The first controller then causes information to be transmitted in parallel on the first and second wireless communication channels to the second controller and the second controller receives the information transmitted in parallel on first and second wireless communication channels. The first and second wireless communication channels are then caused to be inactive, whereupon the first and second controllers are out of communication.
