Li-Fi Technology: Where there is light, there is a network.

What is Li-Fi technology? It means that you only need to tap the light switch to connect to the ultra-high-speed Internet. Li-Fi technology uses visible light for data transmission and uses LED lights as a carrier for wireless transmission. With the help of existing LED equipment, a small chip or module is implanted on the light bulb to turn it into a Li-Fi AP, so that after the Li-Fi AP is connected to the network, other Li-Fi-enabled devices can access the network within range.

Compared with Wi-Fi, Li-Fi is safer. As long as the curtains are closed to prevent the LED light from passing out of the room, the Internet swipe cannot connect to your home's Li-Fi at will, and our personal information will not be intercepted or leaked by criminals.

Most importantly, in places where there is no Wi-Fi signal, such as on planes and in underwater environments, Li-Fi can achieve communication. Besides, Li-Fi can also be used in high-density environments, such as grabbing a red envelope or tickets.

However, it also has a disadvantage. once the light source is cut off, the signal will disappear. If the lights are turned off at night and there is no light source, the network will be disconnected. This is why Li-Fi is still not popular.
