Li-Fi is on its way to the public, as researchers have finally tested it in the real world, and it offers some pretty impressive results.
The technology transmits data using a technique called visible light communication, or VLC, and using the tech, scientists were able to transmit data at a pretty hefty 224 GB per second. Outside of the lab, scientists reported speeds of 1 GB per second, which is a lot less than in the lab, but still represents speeds that are 100 times speedier than the average Wi-Fi delivery.
Li-Fi as a medium uses visible light between 400 and 800 terahertz to transmit data, working basically like an advanced form of Morse code. Light is switched on and off much faster than the human eye can detect, which can be used to write things in binary code.
There are a number of benefits to Li-Fi that don’t have to do with data speeds. For example, Li-Fi networks are far more secure because they use light, which cannot pass through walls. Li-Fi networks will be the end of your neighbors trying to piggyback on your network.
