Li-Fi will be a great advanced technology in Upcoming High Speed Wireless World.This slide is a basic informational Slide about Li-Fi. I hope after reading this slide, You will get the basic knowledge about Li-Fi. This slide was made for my University Presentation. Information was taking from Google.

3. Going To Tell About…..
• Introduction
• History of Li-Fi
• How Li-Fi Works
• Architecture of Li-Fi
• Li-Fi v/s Wi-Fi
• Application of Li-Fi
• Advantages of Li-Fi
• Limitation of Li-Fi
• Conclusion
• Question Answering from Audience

4. Introduction….
• What is Li-Fi (Light Fidelity Technology)?
Delivering Data Through Light
Sensitivity is more than faster than Human Eye can follow
Fast Cheap Wireless Communication System which is optical version
of Wi-Fi

5. History of Li-Fi……
 Professor Harald Haas,from the University Of
Edinburgh in the U.K , is widely recognized as
the orginal founder of Li-Fi.
 The Term was first used in this context by
Harald Haas in 2011 TED Global Talk on
visible Light Communication.
 But, the technology was truly began during
the 1990’s in countries like Germany,Korea &
Japan, where they discovered LED’s could be
retrofitted to send information.

6. How Li-Fi Works…..
 Operational Procedure is very simple, if the LED
is on , then your device transmit a digit ‘1’ & if it
is off ,then your device transmit a digit ‘0’.
 The LED can be switched on & off very quickly,
which gives nice opportunities for transmitting
data.
 Hence, all that required is some LEDS & a
controller that code data into those LEDS.

7. Li-Fi vs Wi-Fi……

8. Application of Li-Fi…….
Vehicles & Transportation
Underwater
Communication
Aviation
Location Based
Services(LBS)
Hospital & Health Care
Mobile Connectivity
Smart Lighting
RF Spectrum Relief
Hazardous Environments

9. Advantages of Li-Fi………
It not impossible to achieve more
than 10 Gbps , theoretrically
allowing a high definition film to be
download in 30 second.
Mostly powered by LEDS so it is cost
efficient.
Transmission of data is fast & easy.
Not easy to Hackable.
Its main advantages is it’s Bandwidth
is 10,000 times than the radio
waves.

10. Limitation of Li-Fi…..
Li-Fi doesn’t work in the dark.
Li-Fi can’t pass through the
solid object like wall.
To connect with Li-Fi , your
device must be stayed under
the LED light which is
connected with Li-Fi.

11. > Conclusion <
Thus ,if Li-Fi technology can be put into practical use every bulb can
be used as an alternative to Wi-Fi & Hot spots. It provides simple ,
faster & efficient wireless data communication . Li-Fi will make us to
proceed towards the cleaner, greener , safer & brighter future.
