3. Abstract
One germen physicist. 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 lightemitting 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.

9. 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

Low Cost

11. Concussion
LI FI will make our lives more
technology driven in the near future.
With its magic of light it can make
our world a greener , safer ,cleaner
and moreover a brighter place to live.
