Classification: CPC H  F | IPC F  H

Claim 13:
14. A method of establishing electromagnetic communication through a waveguide system of a machine, the method comprising:
configuring a network of nodes to communicate using a plurality of electromagnetic signals, wherein the nodes are distributed throughout the machine;
initiating communication, by a controller, with the nodes using electromagnetic signals;
receiving a portion of the electromagnetic signals at a radio frequency-based repeater, wherein the radio frequency-based repeater is in the network between the controller and at least one of the nodes;
operating the radio frequency-based repeater using power extracted from at least one of the electromagnetic signals when a signal-to-noise ratio is above a threshold; and
operating the radio frequency-based repeater using 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.
