Classification: CPC H  F | IPC F  H

Claim 7:
8. A system for a gas turbine engine, the system comprising:
a network of nodes distributed throughout the gas turbine engine, each of the nodes associated with at least one sensor or effector of the gas turbine engine;
a controller of the gas turbine engine; and
a radio frequency-based repeater is in the network between the controller and at least one of the nodes, the radio frequency-based repeater comprising a means for extracting power from at least one electromagnetic signal of the network when a signal-to-noise ratio is above a threshold and using stored energy when the signal-to-noise ratio is below the threshold, wherein the means comprises an onboard energy storage system configured to extract and store a portion of energy received from a transmission to power the radio frequency-based repeater, and the system is a waveguide system.
