3. 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.

4. 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.

11. Working process
LIFI 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

15. Advantages
 High Security
 Easy To Use
 Fast Data Transfer
 Reliable
 Harmless ness
 Low Cost

16. 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.
