A novel wake-up communication system using solar panel and visible light communication

Abstract

One of the most promising energy-efficient communication methods is the use of wake-up receivers. In this paper, we propose and develop a novel wake-up communication system that uses Visible Light Communication (VLC) and an indoor solar panel as the receiver of the wake-up signal. After the reception of the wake-up signal, an interrupt generated by the wake-up receiver wakes up the wireless device attached. Through experiments we show the feasibility of the system and characterize its performances in terms of wake-up probabilities for different distances. We present two configuration options: an addressable and a broadcast-based wake-up configuration. We evaluate the effect of light interferences and show that the achieved wake-up distances under these conditions are reasonable for indoor scenarios.
