Claim Text:
1. An obstruction lighting and power line communication system, comprising: a first controller coupled to and configured to control a first light source; a first transceiver associated with the first light source and configured to transmit and receive telemetry data signals associated with the first light source; a power line cable coupling the first controller and the first transceiver; a power supply coupled to the power line cable and configured to provide power to the first light source over the power line cable; a system controller configured to exchange at least one of a control signal and a telemetry signal with the first controller over the power line cable; a second controller coupled to and configured to control a second light source; a second transceiver associated with the second light source and configured to transmit and receive telemetry data signals associated with the second light source, the power line cable coupling the second controller and the second transceiver, the power supply configured to provide power to the second light source over the power line cable, and the system controller configured to exchange at least one of an additional control signal and an additional telemetry signal with the second controller; a first isolation impedance coupled to the power line cable between the power supply and the power line cable, the first isolation impedance configured to isolate the power supply when the system controller provides at least one control and telemetry signal to at least one of the first and the second light sources; and a second isolation impedance coupled to the power line cable between the system controller and the power line cable, the second isolation impedance configured to isolate the system controller.
