What is the difference between Li-Fi and Wi-Fi?


Wi-Fi uses radio waves to broadcast its signal, whereas Li-Fi uses visible light provided by LED bulbs fitted with special chips and sensors.

Wi-Fi is best for general wireless Internet coverage, while Li-Fi works best in high-density coverage areas within confined areas where Wi-Fi does not operate properly. Because Li-Fi is transmitted via visible light, its signal cannot pass through walls or other barriers, and other sources of light may interfere with its signal.

Li-Fi has the potential to be much faster than Wi-Fi. It is estimated that Li-Fi's theoretical maximum speed could be 100 times that of Wi-Fi.

Although Li-Fi is currently undergoing testing, it is believed that it will become more widely used in coming years.
