Abstract
A method of communication between first and second controllers positioned in spaced relation along a length of a vehicle system includes establishing first and second wireless, parallel communication channels between the first and second controllers. The channels operate at different carrier frequencies. The first controller transmits common information 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 deactivated Subsequently, a single communication channel is established for communicating other, different information between the controllers.
