Light Conversation – Visible Light Communication by Craig Dilouie

Wi-Fi is not the only means of transmitting data these days. Another unique method you may not have heard of is visible light communication (VLC). VLC is a free-space optical wireless communication technology that uses visible light to transmit data across distances. The advent of light-emitting diode (LED) technology in general lighting is creating new opportunities for VLC in the built environment, and major new product offerings are under development.
The principle of optical communication using modulated light is simple. Varying the pattern of a light beam’s intensity encodes information. The light then transmits that information over distances at a speed of 186,000 miles per second.
