Light to be used as future for wireless communication

2. Wi-Fi
Wi-Fi also called Wireless Fidelity, is a
wireless data transmission method using
radio waves between device and router
Discovered by Prof. John o’Sullivian
accidentally while discovering
exploding mini black holes

3. Wi-
FiToday Wi-Fi amounts for about 60 of total
Internet traffic in the world. Without it our
lives are hard to imagine with wires everywhere.
But Wi-Fi has security issues as it can
pass through walls and data
can be intercepted by anyone

4. Our
Need?We need something which is cheap, easily
available, secure and reliable.

5. Answer
LIGHT

6. Why?
Light has higher wavelength than radio waves used by Wi-Fi
Higher the wavelength greater the transfer rate of data

7. Why?
Wi-Fi is leads to security issues as radio wave can pass through walls
and poor network connectivity. Using light makes data transfer safe
and network strength more stronger

8. Li-
FiLi-Fi or Light Fidelity is the use of light in order to
transfer data wirelessly using visible light

9. Li-Fi Working

10. VLC
VLC Visible Light Communication is transfer of data using visible
light. It is the principle behind LiFi.

11. TV Remote
Tv remote uses a single transmission channel
to communicate

12. Li-Fi Driver
Li Fi uses a multiple transmission channel to communicate data at once

13. Uses
Li-Fi can be used underwater communication saving the cost of long
wires and simultaneously using it for navigation

14. Li-Fi can be used in traffic management by data transfer
between vehicles and on the go internet connectivity
without any router
Uses

15. Uses
LiFi can be used in aeroplanes where WiFi use can interfere
with the internal machinery of the aircraft
