Abstract

The concept of visible light communications (VLC), or Li-Fi has received a lot of attention in recent years, mostly due to the growing prevalence of LED lighting. Unlike incandescent and fluorescent bulbs, LEDs are solid-state electronics, meaning they can be controlled in much the same way as any other electronic component, and switched at a high speed. VLC is essentially Wi-Fi but using terahertz radiation (light) instead of microwaves (Wi-Fi). Instead of oscillating a Wi-Fi transmitter, VLC oscillates an LED bulb and of course, on the receiving end there's a photo detector instead of an antenna. LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission.
