Claim 0:
1. A system of a machine, the system comprising:
a network of nodes distributed throughout the machine, the nodes operable to communicate using a plurality of electromagnetic signals through one or more waveguides;
a controller operable to communicate with the nodes using electromagnetic signals; and
a radio frequency-based repeater in the network between the controller and at least one of the nodes, wherein the radio frequency-based repeater is configured to extract power 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, wherein the onboard energy storage system is configured to extract and store a portion of energy received from a transmission to power the radio frequency-based repeater.
