Li-Fi is Hundred Times Faster than Wi-Fi and Uses Light Instead if Radio Frequencies

A new way of sending data, called Li-fi, was successfully tested in an office. Unlike Wi-Fi that uses radio waves, Li-fi uses visible light to give internet access. Li-fi can be much faster, up to 100 times, than Wi-Fi, reaching speeds of 1Gbps (a lot of data per second).

Li-fi works with a light like a regular LED bulb, an internet connection, and a special sensor. A company called Velmenni from Estonia tried Li-fi in Tallinn. They used a Li-fi light bulb to send data at a speed of 1Gbps.

In lab tests, it reached speeds up to 224Gbps!They tested it in an office to give workers internet and in a factory for better lighting. Deepak Solanki, the boss of the company, said this technology might be available for people in “three to four years.”
