An introduction to Visible Light Communication
OpenVLC is the first open-source, software-defined, flexible, low-cost VLC platform

Visible Light Communication (VLC), sometimes also referred to as “Li-Fi”, uses standard off-the-shelf visible light LEDs to transmit data using the visible light spectrum.
VLC is one of the ground-breaking technologies that IMDEA Networks researchers are working on. A research team led by Dr. Domenico Giustiniano is carrying out an important research project called OpenVLC. But, how does it work? The idea is very simple: VLC combines light with data transmission. The light emitted by standard LED luminaries is modulated to transmit data at such high speed that the human eye cannot perceive light changes.
In this video, Ander Galisteo, PhD Student at IMDEA Networks and Universidad Carlos III de Madrid and an awardee of a La Caixa scholarship, provides a simple explanation of the great potential of VLC, a technology in the area of telecommunications that is still in an experimental phase.
Galisteo also explains the benefits of using OpenVLC, the first open-source, software-defined, flexible, low-cost Visible Light Communication platform, which has been designed by IMDEA Networks researchers. At this moment, the research group is looking into scientific problems related to VLC. “We have developed a localization system for cars that only uses light, we have helped to set up and study realistic VLC deployments in other countries and we are measuring the behavior of this technology in dynamic scenarios”, said Galisteo.
