their smart phones, laptops and tabs to communicate with their loved ones through Wireless-Fidelity systems, and these technology is used in all nook and corner of the world including homes, malls ,restaurants, power plants ,industries, harbors, resorts and airports. Due to this wireless systems usage is increasing day by day. As a result radio frequency spectrum is reducing . The solution to this problem lies in light fidelity which overcomes the problem of bandwidth limitation and produces a safer, faster and a secured transmission.
Abstract- With the advancement of mobiles, Internet of
things, Automotive Industry, Live video streams and along with the demand of users, the call for Internet is growing exponentially. This era has advanced a lot such that from our television to satellite wishes a connection to the internet. This leads to questions like: Will there be sufficient bandwidth for a majority use of gadgets? Will the information available will be secure? Whether the information will be transmitted or received in high speed? Will there be good analysis on network traffic? Answers to all these questions will be tackled with the aid of using the upcoming generation technology, Li-Fi (a subset of VLC). Let us see what is Li-Fi. Li-Fi means Light Fidelity. This will be the subsequent generation of net, where light can be used as a channel for transmission. This paper aids to know the information about the future generation, LiFi.

Data will be transmitted with the help of LEDs using the light.
Data will be transmitted using a Wi-Fi router by using the radio waves
Transmission rate
224gbps
150mbps-2gbps
Security
Light can be blocked by any physical object hence this will provides the security.
There is no barrier for radio waves so we need to deploy more techniques to the achieve security.

400THz-800THz
3kHz-300GHz
Distance
About 10m
About 32m
of
It can easily work in any environmental condition .it is more adaptable.
Working environment should not contain any interference related issues
Requirements
LED, Photo detector
Routers, modems
Detector, Audio, Wi-Fi. Principle working
1. INTRODUCTION Light Fidelity, in short Li-Fi is a transmission of the information (text, audio) using the visible light communication technique that is by using the light as a communication medium of transmission. In the current generation, Wi-Fi and Bluetooth are the main means used for communication. Wi-Fi and Bluetooth uses the Radio Spectrum of Electromagnetic Radiation in order to transmit the information. But the spectrum of radio wave available for transmission is less to occupy the millions of users. Hence to cop up with the limited bandwidth of RF wave we need an alternative that is Li-Fi, where the bandwidth is 10000 times more than the RF spectrum. In Li-Fi the transmission of data takes place at 224 gigabits rate, which is 100 times faster than the current technology.
1.1 How Li-Fi is more advantageous than Wi-Fi?
Density Data
Transferring the information from one area to other is the main day-to-day activity. The current technology that we are using today, Wi-Fi and Bluetooth are very slow when many users are connected. As the number of users access the internet, the limited bandwidth get congested as a result the internet speed cuts down and we cannot enjoy the high speed data.in this digital era each and every users are using
