Li-Fi stands for Light-Fidelity. Li-Fi technology, proposed by the German physicist—Harald Haas, provides transmission of data through illumination by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. This paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues. Lifi is a visible light communications system. lifi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission. speed of 100 times faster in testing. large amount of radio spectrum.
Wireless converge, high density, 100 times faster testing, radio spectrum, bulb intensity.
