LED lights with LIFI, LAN data transmission up to 3Gb per second

Recently, the German Fraunhofer Henrich Hertz Institute (hereinafter referred to as HHI) announced in a laboratory environment, the use of ordinary LED lighting, the successful implementation of the data transmission speed of 3Gbps, the scene in real life (such as exhibition), the system can reach the speed of 500Mbps.

Visible light communication (Visible Light, referred to as VLC), and sometimes it is also known as LIFI (Communications). In recent years it has received a lot of attention, a very important reason is that LED lighting is becoming increasingly popular.

Unlike incandescent and fluorescent lamps, LED is a solid-state electronic device, which means that it can be controlled like other electronic components, and to achieve high-speed conversion. VLC is essentially WiFi, but it uses a terahertz radiation (light), rather than microwave (WiFi), of course, its receiving terminal is a photodetector, rather than an antenna.
