Abstract
A system of a machine includes a network of nodes distributed throughout the machine. Each of the nodes is operable to communicate using a plurality of electromagnetic signals. A controller is operable to communicate with the nodes using electromagnetic signals. The system also includes a plurality of waveguides configured to guide transmission of the electromagnetic signals between the controller and one or more of the nodes. A radio frequency-based repeater is coupled to at least two of the waveguides in the network between the controller and at least one of the nodes. The radio frequency-based repeater is configured to operate using power extracted from at least one of the electromagnetic signals when a signal-to-noise ratio is above a threshold, and the radio frequency-based repeater is configured to use energy stored in an onboard energy storage system when the signal-to-noise ratio is below the threshold.
