Abstract

Now-a-days, Wireless technology has bloomed to a great extent that it requires wireless technology to transmit a lot of data every day. Moreover, Wireless communications has become important in each and every communication process. The simplest way to transmit wireless data is by making using electromagnetic waves which is also known as radio waves. As we all know, Radio waves can support less bandwidth because of intrusion and compact spectrum availability. Visible Light Communication (VLC) is the solution to this is data transmission. Wi-Fi provides us with wireless coverage within premises, whereas Li-Fi is said to be perfect for high compactness wireless data coverage for defined area and also for mitigating radio interference problems. In Li-Fi, basically we deal with transmitting multimedia data between two terminals with the use of LED\'s. Li-Fi focuses on transmission of data through illumination, in which data can be sent through a LED light bulb which may varies in intensity faster than human eye can follow. The light which is used in our daily life is not only used in providing light but also helps in communication by illumination. Transmission of image through LiFi technology is done easily.
