With a strong background in signal procession, communication and information theory and in electronics, we are eager to connect to the further the wide range of local strengths in the human interaction with light, intelligent lighting systems, the Internet of Things (IoT), but also to the ambitions in LiFi, optical wireless communications and photonics.

Smart Lighting feeding our personal well-being and Smart Lighting as an ultra-dense IoT communication Infrastucture

We study novel concepts for Smart and IoT Connected Buildings and also for Wireless Optical Communication (LiFi). One of our success factors is that start by deeping the scientific understanding of lighting and communication via light. We develop effective, yet computationally-efficient non-linear equalizer structures to enhance LiFi, by first improving the models of the photonic response of LED junctions, studying semiconductor physics. We translate these new insights into efficient equalizer structures, optimized modulation methods and suitable electronic driver circuits. To make LiFi robust against interruptions of a light beam, we develop OFDM MIMO schemes in which multiple distributed light sources cooperate to boost reliability and performance.

Another research track is the translation of scientific insights in the human experience of light into computer-interpretable control algorithms that optimize acute effects on comfort and productivity jointly with the impact on circadian rhythms and sleep and energy efficiency. We study how such dynamic control systems can work with imperfect sensors and constrained IoT communication networks.

We cooperate internationally with major institutions and companies, in national and EU projects, and in particular we have a track record of cooperation with Signify (Philips Lighting).
