Visible Light Communications

In last few years, we have seen a growing research in visible light communications (VLC), and the idea of using LEDs for both illumination and data communications. The main drivers for this technology include the increasing popularity of solid-state lighting, longer lifetime of high-brightness LEDs compared to other sources of artificial light like the incandescent light bulbs, high bandwidth/data rate, data security, no health hazards and low power consumption. The dual functionality provided by VLC (i.e., lighting and data communication from the same high-brightness LEDs) has created a whole range of interesting applications, including but not limited to home networking, high-speed data communication via lighting ...
