Integrated LiFi(Light Fidelity) for smart communication through illumination

Abstract

Wireless technology has bloomed to a great extent that it require wireless technology to transmit a lot of data every day. Nowadays, wireless communications has become important in communication process. The main way to transmit wireless data is by using electromagnetic waves i.e. radio waves. However, radio waves can support less bandwidth because of compact spectrum availability and intrusion. Solution to this is data transmission using Visible Light Communication (VLC). Wi-Fi deals with wireless coverage within premises, whereas Li-Fi is perfect for high compactness wireless data coverage in defined area and for mitigating radio interference issues. In Li-Fi basically we focus to transmitting multimedia data between two terminals using LED's. Li-Fi is a transmission of data through illumination, in which data can be sent through a LED light bulb that varies in intensity faster than human eye can follow. The light which we are using in our daily life is not only used for providing light but also for communication by illumination. Transmission of image through LiFi technology is done. Using visible light for data transmission including many advantages and eliminates the disadvantages of transmission of data through electromagnetic waves.
