Simply Light Fidelity. This technology has a facility to transmit data with the help of light. A German phycist Harlad Hass came up with this Light Fidelity.
We know data can be transmitted in two ways. It can be done through wired cable and by wireless. In the past olden days data transmission took with the help of electronic signals. Days passed away, and came up with wired transmission. The people doesn't satisfied with this wired transmission. Then wireless network came in to existence. It has a wide range of applications. Without connecting a wire we can transmit data. So people not satisfied with this innovation. Many researchers trying to implement many ideas to transmit data in many ways. This German phycist Harlad Hass chosen electrical data transmission.
What is Light Fidelity?
In Light Fidelity the data can be transmitted with the help of lights. This is called as data through illumination. Sending through an LED light bulb that varies in intensity faster than the human eye can follow.

Main advantage of this LiFi is it can be used in RF restricted areas. Because data transmission of wireless is done through radio spectrum. And we can also use this in ocean beds, in aircrafts, down under the street lamps.
Remember about one thing, light cannot travel through a solid content For example wall, metal, steel etc. This is the only disadvantage of this LiFi.
But its not a big deal to scientist. Lot of happened in this universe only by humans. Research have been going through to get rid of this issue.
