How is Li-Fi different than Wi-Fi?

What’s the difference between Li-Fi and Wi-Fi? How does Li-Fi work?
WiFi transmits data with the help of WiFi router using radio waves whereas Lifi transmits data with the help of LED bulbs using light. LiFi has less interference issues as compare to WiFi.
Li-Fi uses visible light communication to transmit data. Basically flickering a light on and off based on a specific pattern to transmit a message.
The big benefit of Li-Fi is its speed which is much faster then Wi-Fi permits. Estonian scientists were able to achieve 224 gigabits per second speeds in a lab environment. Another potential benefit is security. Because light is constricted to a specific area and doesn't pass through objects such as walls, someone from outside can't easily get onto the network.
