| Summary: | [ANGLÈS] One of the most promising energy-efficient communication methods is the use of wake-up receivers. In this work we propose and develop a wake-up communication system that uses Visible Light Communication (VLC) and an indoor solar panel with two functions: act as the receiver of the wake-up signal and harvest power from the light. After the reception of the wake-up signal an interrupt generated by the wake-up receiver wakes up the wireless device attached. Two configuration options are presented: an addressable and a broadcast-based wake-up configuration. In addressable configuration, after the reception of the wake-up signal a comparison is made with the identification code configured in the device; as consequence only the device with the match code is woken up. In broadcast-based wake-up configuration the wireless node attached wakes up after the detection of the carrier burst frequency, allowing use this system for wake up several nodes at once. Two options of configuration for the receiver are presented, and also the design of a transmitter who copes with flickering mitigation. Through experiments the feasibility of the system is shown and its performances is characterized in terms of wake-up probabilities for different distances. The effect of light interferences is evaluated, which shows that the achieved wake-up distances are reasonable for indoor scenarios. |
