The Times of India reports that Chinese scientists have succeeded in developing a new and cheaper way of getting connected to the Internet.
This new technology, dubbed as ‘Li-Fi’, uses signals sent through light bulbs instead of radio frequencies which is currently used in Wi-Fi.
This new discovery is expected to radically change the process of online connectivity. According to the scientists four computers can be connected to Internet through a single one-watt LED bulb. By doing so the LED bulb will be used as a carrier. This light bulb, that has been provided with embedded microchips, can produce data rates as fast as 150 megabits per second, according to Chi Nan, an information technology professor at Shanghai’s Fudan University.
The Li-Fi technology is much more cost-effective as well as efficient compared to the currently used Wi-Fi technology. As professor Chi puts it: “Wherever there is an LED light bulb, there is an internet signal. Turn off the light and there is no signal.”
However he also states that there is still a long way to go to make Li-Fi a commercial success. The technology is still in a early stage of development.
