Nowadays wireless technology is in the trends and it becomes important communication process. The main way to transmit the data is by 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). Solution to this is data transmission using Visible Light Communication. A new wireless technology was introduce called Li-Fi. The technology is very new and was proposed by the German physicist Harald Haas in 2011 TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC). Li-Fi provides better bandwidth, efficiency, connectivity, and security than Wi-Fi and has already achieved high speeds larger than 1 Gbps under the laboratory conditions. In Li-Fi basically, we focus on transmitting multimedia data between two terminals using LED. It is a transmission of data through illumination. LED light bulb that varies in intensity faster than the human eye can follow. By leveraging the low-cost nature of LEDs and lighting units, there are lots of opportunities to exploit this medium.
