Visible Light Communications


Chair: Luis NERO

Vice-Chair: Roger GREEN


Light Emitting devices, usually known as LEDs, are becoming ubiquitous devices. Since their early days as light indicators in electronic equipment, much has changed. Nowadays, LEDs are used mostly as illumination devices. Their longer lifetimes, promised energy savings and enhancedcontrollability have promoted their adoption as the future illumination devices. LEDs are currently applied for indoor illumination, automotive applications and public street illumination among others. Being solid state devices, LEDs support fast switching, a feature that is currently explored for dimming purposes. Fast switching can also play a key role in visible light communication (VLC) systems. There are several proof-of-concept examples showing the possibility of using LEDs for both illumination and communication. Most of these examples addressed applications concerning indoor scenarios and also automotive applications. It has been demonstrated that LEDs can support nearly 1Gbps transmission rates for indoor scenarios. These examples show that VLC technology has a great potential as a last mile access technology. Moreover, bearing in mind the fast growing LED market, a large number of synergistic opportunities may emerge in the near future.

The visible light communications special interest group, VLC-SIG, is an application-driven SIG. Integrated with the activities of the IC 1101 OPTICWISE COST action this SIG will address high potential applications of VLC technology. Contrary to the other OPTICWISE working groups (WG), the VLC-SIG will not address fundamental science or methodologies.
