Project Summary

The main theme and idea behind this project is to transfer data from one place to another using visible light. This technique is known as Li-Fi. Li-Fi is a latest and efficient technology of wireless communication between devices at a very high speed nearly upto 150gbps. This term was first introduced in 2011 by Harald Haas durind TEDGlobal talk in Edinburgh.

In its present state LED lamps can be used for transmission of data through visible light. This emerging technique is quite different from Wi-Fi and donot involve radiations for data transmission. By using this technique, we can transfer data of any kind internet, music and other, from one place to another within no time delay.

Using light to transmit data allows Li-Fi to offer several advantages like working across higher bandwidth, working in areas susceptible to electromagnetic interferences (e.g aircrafts cabins, hospitals) and offereing higher transmission speed. 

In this project, we are deploying it in open enviroment. We are transmitting an audio file from computer of one department to computer of another department using visible light within university. So, our project shall deployed at commercial level i.e within our university.

In the era of technology, where bandwidth and speed of internet is a major issue. Li-Fi works on a speed of light and bandwidth is not a issue in it. 

Further more light cannot penetrate through walls and door so if we design a lab using Li-Fi, the most important keypint will be security especially in those area where critcal and important data is handled.

As it is said that  Li-Fi is the future of Wi-Fi, so this project wil be the first step towards future. Its efficient, less costly and also it consumes less power for its working. 

Project Objectives

The main purpose of this technology is to transmit data at a very high speed nearly upto 150gbps within no time delay.

Further more security is also part of its objective as light cannot penetrate through walls and doors. Its much secure than Wi-Fi as no one can access data from outside the room.

In aircrafts we cannot use Wi-Fi because of its radiations, so   Li-Fi can be use there for data transmission.

Li-Fi is designed and deployed in close enviroment in the past years but we are deploying it in open enviroment i.e we are transmitting data from computer of one department to computer of another department using visible light within the university.

Project Implementation Method

In our project we shall transfer an audio file from computer of one department to computer of another department through visible light. We have two modules such as transmitting and receiving module. Both modules are placed in different departments, its means we are transferring data to one department to another within university. So we are deploying  it at a commercial level. 

Li-fi is being tested and deployed in closed enviroment in the past years but we are designing this project in open enviroment. 

First of all sender from computer A sends an audio file to Computer B of another department through visible light or LED. The arduino detects the data and  LCD shows data transmission process on its screen to assure that data is being transmitted. The transmitting module will convert the audio data coming from the laptop into light by encoding process and and transmit it to receiver. Then the receiving module detects the data is being received and LCD shows Data Received on its screen and it starts performs decoding process. After that amplification of audio data shall take place. Now, the audio file can be heard or played at the the receiver side.

Benefits of the Project

Using light to transmit data allows Li-Fi to offer several advantages like working across higher bandwidth, working in those areas which are susceptible to electromagnetic interferences (e.g aircraft cabins, hospitals) and offereing higher transmission speed.

In contast to radio frequency wave used by Wi-Fi, light cannot penetrate through walls and doors. This make it more secure and more easy to control access to a network.

Many treatments now involve multiple individuals, Li-Fi systems could be better system to transmit communication about the information of patients. Besides providing the higher speed, light waves also have little effect on medical instruments and human bodies.

Vehicles could communicate with one another via front and back lights to increase road safety. Street lights and traffic signals could also provide information about current road situation. 

Anywhere in industrial areas data has to be transmitted,      Li-Fi is capable of replacing slip rings, sliding contacts and short cables, such as Industrial Ethernet. Due to the real time capability of Li-Fi (which is often required for automation processs) it is also an alternative to common industrial Wireless LAN standards.

As it uses visible light for transmission and no radiations are linked with it, it will create green and clean bright future. 

Technical Details of Final Deliverable

The final deliverable sysyem is capable of wireless data transmission through visible light at a very high speed nearly upto 150gbps within no time delay.

We are transmitting data from the computer of one department to the computer of another departement at a distance so we are deploying it in an open enviroment. So we are commercially deploying our project within our university.

We are presented this project which is more secure, clean from radiation and have higher speed and bandwidth
