Li-Fi (Light Fidelity) is a cutting-edge wireless communication technology that uses LED light to transmit data—offering speeds up to 100 times faster than traditional Wi-Fi.
Unlike radio wave-based Wi-Fi, Li-Fi transmits data using visible light, making it highly secure and free from radio interference. Since light can’t pass through walls, Li-Fi provides enhanced data privacy and limited signal leakage—ideal for sensitive environments like hospitals, banks, and defense facilities.
Li-Fi can also operate in RF-restricted areas and improve bandwidth efficiency in crowded networks. While still in early stages of consumer adoption, companies are exploring Li-Fi for smart lighting systems, office networks, and industrial automation.
Challenges include line-of-sight requirements and daylight interference, but advancements in infrared-based Li-Fi are addressing these hurdles.
As data demand grows, Li-Fi stands to revolutionize wireless communication with faster, greener, and safer connectivity.
