The second kill WiFi technology allows you to download 23 movies in one second

A new wireless Internet technology called Li-Fi features amazing ultra-fast speed, allowing you to "Download 23 DVD movies in 1 second ".

Li-Fi is short for Light Fidelity, a technology called "Light Fidelity" or visible Light wireless communication technology. It sends Internet data through LED Bulbs rather than wi-fi radio waves.

The LED bulb emits an optical frequency through high-speed flashing, which transmits data at an extremely high speed and can reach 200 GB per second.

"The speed at which Li-Fi transmits data is 100 times that of Wi-Fi ." Suat Topsu, founder of the French Li-Fi startup company Oledcomm, said.

At the global mobile exhibition, Oledcomm demonstrated its Li-Fi technology. It places a smartphone in the light of an LED bulb and downloads the video from the Internet. This smartphone is not connected to a Wi-Fi router or any device that provides network connections. It is only wirelessly connected to the light bulb.

In addition to high-speed Internet access, the Li-Fi technology has many advantages.

Li-Fi is safer than Wi-Fi because, unlike radio waves sent by Wi-Fi, light cannot penetrate the walls. This means that only people in the same room with the Li-Fi light bulb can connect to your internet, and others have no chance to get rid of the Internet.

Moreover, in some places, Wi-Fi radio signals may cause interference, while Li-Fi does not. For example, in hospitals, Li-Fi does not interfere with medical devices as Wi-Fi radio signals do.

Of course, everything has advantages and disadvantages.

First, your device needs to be directly exposed to the Li-Fi light bulb. If the light is blocked, you may not be able to access the Internet. For example, if you block your hand between your device and the Li-Fi light bulb, your signal will be interrupted. Let's take a look at the video of Velmenni, another Li-Fi startup company.
