PureVLC brings its first Visible Light Communication (VLC) product to the market. VLC transmits data wirelessly using visible light as its medium instead of radio waves.

He streamed a HD video to a screen using a LED light bulb as transmitter.

 

Using the visible light spectrum to transfer data wirelessly will ease the burden on the overcrowded radio frequencies. The visible light spectrum is 10,000 larger than that of radio. VLC can potentially realize ultra-high-speed transfer rates and high data density.
