Abstract | A locomotive communication system includes a lead communication device wirelessly communicating command messages to remote communication devices onboard a rail vehicle system during a messaging cycle. The lead device receives reply messages from the remote devices during the messaging cycle in response to the command messages. The lead device receives a status signal from at least one of the remote devices during a guard interval that follows completion of the messaging cycle. The lead device communicates the command message and receives the reply messages using analog modulation or digital modulation. The lead communication device also receives the status signal using the other of the analog modulation or the digital modulation. The command messages, the reply messages, and the status signal are communicated using a designated frequency channel. |
