Li-Fi

Li-Fi, short for Light Fidelity, is a wireless communication technology that uses visible light, typically from LED bulbs, to transmit data. Unlike Wi-Fi, which relies on radio waves, Li-Fi sends information through rapid modulation of light signals, which are too fast for the human eye to notice. This allows for high-speed internet connections that are secure and less prone to interference. Li-Fi can be especially useful in environments where radio frequency signals are restricted or crowded, such as hospitals or airplanes. Overall, it offers a fast, reliable, and innovative way to connect devices through existing lighting systems.
