A new technology called LiFi can transfer data using LED lights. In this video, we’ll watch a demo of a LiFi system made with off-the-shelf-parts, as it streams a vide.

LiFi is a light communication technology which is theoretically capable of transmitting data at high speeds over different media, such as the visible light, ultraviolet, and infrared spectrums.

Light might be the preferred option for transmitting data over long distances via cables, but when it comes to short range wireless, radio waves rule in the form of Wi-Fi and Bluetooth. Now ...
