LI-FI (Light Fidelity)-The Future Technology in Wireless Communication

Li-Fi is a new wireless technology to provide the connectivity with in localized network environment .As in practical term whether you’re using wireless internet in a coffee shop ,stealing it from the guy next door, or competing for bandwidth at a conference you may get frustrated at the slow internet speed you face when more than two device is tapped into a network. Now a days with the advent of technology,, communication became the backbone of ICT. ICT had made our globe like a town. Today everyone (Business , institutions ,organizations ,entrepreneurs )is thrust for getting right information at the right time and right place .Which, requires fast internet connectivity, Technology and large spectrum of channels. Present paper reflects the Future of Communication (LIFI) which may affect all lives. One German physicist , DR. Harald Hass , has come up with a solution he calls “ Data through illumination” taking the fiber out of a fiber optics by sending data through an LED light bulb that varies in intensity faster than the human eye can follow .DR. HASS says these invention, which he calls D-Light, can transfer data more than 500MBPS (30GBPS per minute) an alternative, cost effective and more robust and useful than Wi-Fi. The Visible light communication which may be the future of Internet.
