What is LiFi?
Where our current WiFi stems from radio waves, LiFi (light fidelity) transmits data through LED light bulbs.
With visible light, LiFi is able to transmit information at seriously high speeds. Using a photo-detector, light signals are received, and then converted into ‘streamable’ content. All of this is naked to the human eye.
To put it more simply, data is fed into an LED light bulb, which can then transmit it through its beam at rapid speeds into a photo-detector, providing you with Internet.
