Technology

Introduction

Li Fi means “Light Fidelity”. At the heart of this technology is the new generation Of high brightness Light emitting diodes. It is possible to encode data in light by varying the rate at which the LEDs flicker on and off to give different string of 1’s and 0’s

Present Scenario

1.2 million 5 billion

Issues with radio waves

Electro magnetic spectrum

Different between the technologies

Working Process

LIFI offers an integrated light source that is straightforward to integrate into a projector. In this example consist of 5 primary sub-assemblies:

Printed circuit board(PCB)

RF power amplifier(PA)

Bulb

Enclosure

Users of LI-FI

Potential Application of LI-FITraffic lights

Intrinsically safe environment

Public internet Hotspot

On ocean beds

Advantages

High security

Easy to use

Fast data Transfer

Reliable

Harmless ness

Low cost

Conclusion

The possibilities are numerous and can be explored further. If his technology can be put in to practical use , Every bulb can be used something like a WI-FI hotspot to transmit wireless data and we will proceed towards the cleaner, greener ,safer and brighter future.
