presentation about Li-Fi

Li-Fi is a light-based communication technology invented by Harald Haas in 2011. It transmits high-speed data using LED bulbs, where light dimming encodes binary signals decoded by photodetectors. Compared to Wi-Fi, Li-Fi offers faster and more secure connections but has a shorter range and light dependency. Its architecture includes LEDs and photodiodes enabling localized networks. Applications range from secure environments like hospitals to IoT systems and underwater communications. Li-Fi...
