OpenVLC platform for research in Visible Light Communication Systems

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. The idea is very simple: 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 other terms, VLC is “like sending Morse code signal with a torch, but a much faster rate and using the alphabet that computers understand,” says one expert.
