Design and implementation of zero power wake-up for PLC modems in smart street lighting systems
One of the main challenges of the smart grid applications is relying on efficient communication infrastructure and service. Important applications, such as smart lighting, use Power line communication (PLC) on the pre-existing infrastructure. Nevertheless, this protocol is not energy efficient when communication is sporadic. In this paper, we propose a method to eliminate the energy consumption in street lights during the stand-by mode. The proposed wake-up system permits to avoid waste of energy of the PLC modem when communication is not present on the line. Experimental results compare different design choices to achieve an optimized design.
