In simple terms, Li-Fi enables internet and data transfer through light bulbs.<\/p>\n<p data-start=\"384\" data-end=\"757\">The concept was first introduced by the German physicist and professor <span class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\"><span class=\"whitespace-normal\">Harald Haas<\/span><\/span> during a TED Global talk in 2011, where he demonstrated how LED lights could transmit video data at high speed. Since then, Li-Fi has evolved into a promising alternative or complement to Wi-Fi, especially in environments where radio waves are limited or insecure.<\/p>\n<p data-start=\"759\" data-end=\"1063\">Li-Fi is based on the principle of Visible Light Communication (VLC), where LED lights are switched on and off at extremely high speeds\u2014so fast that the human eye cannot detect it. These rapid light fluctuations encode data that is received by a photodetector and converted back into digital information.<\/p>\n<hr data-start=\"1065\" data-end=\"1068\" \/>\n<h2 data-start=\"1070\" data-end=\"1101\"><span class=\"ez-toc-section\" id=\"2_What_is_Li-Fi_Technology\"><\/span>2. What is Li-Fi Technology?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"1103\" data-end=\"1267\">Li-Fi stands for Light Fidelity and refers to a bidirectional, high-speed, and fully networked wireless communication system that uses light instead of radio waves.<\/p>\n<p data-start=\"1269\" data-end=\"1438\">It uses LED bulbs as transmitters and photodiodes as receivers. The LED light intensity is modulated to encode data, and this modulation is decoded by a receiver device.<\/p>\n<p data-start=\"1440\" data-end=\"1617\">Unlike Wi-Fi, which uses radio frequency spectrum, Li-Fi uses the visible light spectrum (and sometimes infrared and ultraviolet bands), which is much larger and less congested.<\/p>\n<hr data-start=\"1619\" data-end=\"1622\" \/>\n<h2 data-start=\"1624\" data-end=\"1645\"><span class=\"ez-toc-section\" id=\"3_How_Li-Fi_Works\"><\/span>3.
