Today, the internet is the most popular tool that a lot of people who have computers or other smart devices use to find information. This popularity can be attributed mainly to the speed of the internet when compared with other research sources. In most homes, the average wireless connection speed is about 11 megabits per second, which is much faster than going to the library and checking out books to obtain information. However, things are about to become even faster not through a better wi-fi speed, but through a laser light that transmits information into home devices including computers, smartphones, and tablets at 2 GB per second! That’s almost 1600 times faster than the average wi-fi connection! In fact, Samantha Cole, an author of the Popular Science magazine, explains, “They claim it’s able to move 2 GB per second, or the size of a feature-length movie, faster than it’s taken you to finish reading the last three words of this sentence.” The new technology is called Li-fi and was developed in Saudi Arabia as a visible light communication system. It works by transmitting binary code into devices by the rapid flickering of LED lights. This technology allows you to have a light source while also telling your TV to stream a movie on Netflix. Just think, in the future you may use the same light bulb to light up your room and also research ideas for an upcoming science fair project!
