Özyeğin University is a private, non-profit university in Istanbul founded in 2007. Along with ten other institutions and industrial companies, Özyeğin is a partner in the EU-funded VISION ITN project, based in Marseille, France. VISION—an acronym for "visible light-based interoperability and networking"—aims to train a new generation of early-stage researchers in the emerging area of visible light communication (VLC) and equip them with the latest research.

The main goal of the VISION's VLC research is to develop technical and practical insights into the use of light fidelity (Li-Fi), a VLC technology that offers an alternative to Wi-Fi by running wireless communications based on light-emitting diodes (LED) transmission. Channel modeling for a VLC system—especially in outdoor applications—must account for a wide variety of possible obstructions in order to provide meaningful input into a system design.
