Abstract
A communication apparatus includes an operation module configured for communication with a wireless message repeater, e.g., a rail vehicle distributed power message repeater. The wireless message repeater is of the type having an antenna system, a receiver for receiving an incoming message, and a transmitter for transmitting a repeat message of the incoming message. The operation module is further configured to assess operation of the message repeater by comparing a feedback signal to the incoming message. The feedback signal may comprise part of a signal energy of the transmitted repeat message as received by the receiver. Alternatively or additionally, the operation module is further configured to assess operation of the message repeater by comparing at least one signal power associated with the transmitted repeat message to at least one threshold.
