Abstract:

Nowadays many people are taking interest as to accomplish their tasks through wired or wireless networks. As numbers of users get increased in wireless network the speed reduces proportionally. Though Wi-Fi gives us speed up to 150 Mbps as per IEEE 802.11n. it is still insufficient to accommodate desired no of users. To remedy this limitation, we are introducing the concept of Li-Fi. As per German physic Harald Haas “data through illumination” –taking the fiber out of fiber optic by sending data through an LED light bulb that varies in intensity faster than the human eyes can follow. It’s the same idea band behind the infrared remote controls but far more powerful. Haas says his invention, which he calls D-LIGHT, can produce data rates faster than 10 Mbps, which is speedier than average broadband connection. Twentieth century is an era of internet. Most of the communications happen over the internet. Wi-Fi is the currently most advanced technology that is being widely used for connecting to the internet. The speed and the number of users that can connect at a time are limited in Wi-Fi. Our project is about visible light communication. This communication happens using light as a medium. As light is going to act as a medium the speed will be tremendous for data transmissions. Not only speed but also the security in a closed environment will increase with the use of Li-Fi. Our project aims at exploring the use of Li-Fi also known as optical wireless communication.
