Abstract
One germen phycist. Harald Haas has come up with a solution he calls “data through illumination” –taking the fibber out of fibber optic by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. It’s the same idea band behind infrared remote controls but far more powerful. Haas says his invention, which he calls D- LIGHT, can produce data rates faster than 10 megabits per second, which is speedier than your average broadband connection.

Introduction
Li-Fi means “Light Fidelity”. At the heart of this technology is a
new generation of high brightness light-emitting diodes
It is possible to encode data in the light by varying the rate at which the LEDs flicker on and off to give different strings of 1s and 0s.

Working processLIFI offers an integrated light source that is straightforward to integrate into a projector. In this example LIFI consists of 5 primary sub-assemblies:
Printed circuit board (PCB) RF power amplifier (PA) Bulb Optics
Enclosure

Concussion
The possibilities are numerous and can be explored further. If his technology can be put into practical use, every bulb can be used something like a Wi-Fi hotspot to transmit wireless data and we will proceed toward the cleaner, greener, safer and brighter future.
