Abstract

As time passes, the optical wireless communication systems (OWC) are seeing more and more technological advancement. The complete replacement of conventional lighting with LED based solutions seems to be in sight. Technology and its development always match the world's current needs, and as the whole economy is shifting towards ecology and sustainability, moving towards low consumption LEDs would seem to be a good approach. The LED's ability to switch on and off at a fast rate enables the possibility of developing new optical communication systems. In Visible Light Communication (VLC) systems, the LEDs represent the transmitter and the photodetectors represent the receiver. A similar technology to VLC, known as Optical Camera Communications (OCC) uses image sensors as the receiver. The paper investigates the performances of different OWC technologies and provides a detailed overview of the areas and applications in which they can be found.
