· Objective: tranferring data through an LED bulb

· Description:

Imagine a world where you can connect to high-speed internet by just flicking on your light switch. In simpler terms, LiFi is considered to be a VLC (visible light communication) wifi which uses light instead of radio waves to transmit information. LiFi is used to deliver a couple of advantages such as working in areas susceptible to electromagnetic interference like hospitals and aircraft cabins and working across higher bandwidth while offering higher transmission speeds. The technology makes a LED light bulb emit pulses of light that are undetectable to the human eye and within those emitted pulses, data can travel to and from receivers. Then, the receivers collect information and interpret the transmitted data. This is conceptually similar to decoding Morse code but in a much faster rate — millions times a second.
