Li Fi Technology Abstract

Present scenario 14 million 5 billion 4. Li fi is transmission of data through illumination sending data through a led light bulb that varies in intensity faster than human eye can follow german physicist dr.

How Lifi Will Make Common Wifi Problems Obsolete

Li fi is a new exemplar for photosensitive wireless technology to provide unprecedented connectivity within a localized data centric environment.

Li fi technology abstract. This paper attempts to clarify the difference between visible light communication vlc and light fidelity lifi. Li fi is a vlc visible light communication technology developed by a team of scientists including dr gordon povey prof.

Li fi is a label for wireless communication systems using light as a carrier instead of traditional radio frequencies as in wi fili fi should not be confused with the more general term visible light communications vlc which is the use of the visible light portion of the electromagnetic spectrum to transmit information.

There has been a complete shift in wireless technology due to increase demand for faster and more secure and protected data transmission. That is it uses light instead of radio waves to transmit information. Li fi is a wireless optical networking technology that uses light emitting diodes leds for transmission of data.

What is li fi. Li fi or light fidelity refers to 5g visible light communication systems using light emitting diodes as a medium to high speed communication in a similar manner as wi fi13 in the days where internet has become a major demand people are in a search for wi fi hotspots. And instead of wi fi modems li fi would use transceiver fitted led lamps that can light a room as well as transmit and receive information.

The term li fi was coined by prof. In simple terms li fi can be thought of as a light based wi 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.
