LI-Fi is a new technology that uses LED lights to transmit data wirelessly. It works by switching the LED lights on and off very fast to transmit digital 1s and 0s. This provides opportunities to transmit large amounts of data wirelessly through lights. 5G technology will provide complete wireless communication with almost no limitations, allowing high definition video streaming and faster data transmission speeds than previous generations. Skinput uses sensors in an armband to detect vibrations on the skin from finger taps, allowing users to control devices by tapping on their arm. Ambient backscatter harvests existing signals in the air and converts them to power wireless communication devices without needing an internal power source.

5. WHAT IS LI – FI ?
 LI-FI is transmission of data through illumination
,sending data through a LED light bulb that varies in
intensity faster than human eye can follow

7. How LI-FI Works ???
• If the led is on, you transmit a digital 1, if its off you
transmit a 0.
• The LEDs can be switched on and off very quickly,
which gives nice opportunities for transmitting data.
• Hence all that us required is some LEDS and a
controller that code data into those LEDs.

27.  A world without INTERNET is unimaginable.
 What are the features of Next generation
Internets?

The answer is. .

28. Imagine ???
If I say a “Hi” to you and you hear it after
2 Hours !!!!!
This is the problem of
COMMUNICATION outside the
planet.

29. What is an IPN?
network that connects a series
of Internets.
These internets would be
located on planets and moons,
or aboard spacecraft.
Earth's nervous system
expands outwards across the
solar system and beyond.

ambitious mission
CHANDRYAAN…!?
and many more. .

31.  How does failure happen??
 It happens when communication with


satellite breaks.
What is a solution?
Answer is……

32. •End-to-end information flow across the solar system
•Layered architecture for evolvability and interoperability
•IP-like protocol suite tailored to operate over long round
trip light times
•Integrated communications and navigation services

35. Ambient
Backscatter

37. allows devices to interact and send data from one to
another without having any source of power
harvests all the existing signals in the air and converts
them into power for communication devices
absorbs all the different kinds of transmissions all
around us in the air, from radio waves, TV and cell
signals to mobile networks and Wi-Fi
transforms them to both a source of electricity and a
medium for battery-free communication.
