The world does not stand still, so do technologies, and the internet connection is not an exception. The rapid evolution of innovation technologies brings bad news for Wi-Fi: today a light bulb can help you surf on the web 100 times faster. That means the new development is able to offer up to one gigabit per second.
This wireless technology was invented by Harald Haas, professor from the University of Edinburgh. It is quite similar to Wi-Fi connection, however, it does not use radio waves but transmits information through light instead. Which means Li-Fi connection involves a light source like a LED bulb along with the internet access. Moreover, the technology has a number of significant advantages over its popular predecessor.
