China could soon be connecting to the internet through lightbulbs.
Scientists in Shanghai have invented a lightbulb which produces a 150 Mbps Wi-Fi signal and it’s believed that this technology could represent a more efficient method of connecting to the web.
The ‘Li-Fi’ bulbs have a microchip that produces web signals through light frequencies rather than radio waves. Up to four computers can get online using one bulb and they will enjoy speeds faster than the national average. It’s been suggested that the bulbs represent a cheaper and more energy efficient method of connecting to the web as well.
The researchers will demonstrate the technology at the China International Industry Fair in Shanghai on November 5.
According to dailymail.co.uk, the major stumbling block is that the lightbulbs need to be on in order to emit a Wi-Fi signal.
Nevertheless, University of Edinburgh professor Harald Haas, who played a key role in the original formation of the technology, believes that it could one day represent the primary method of connecting to the web.
Speaking to theregister.co.uk, he said: “In the future you will not only have 14 billion (LED) lightbulbs, you may also have 14 billion Li-Fi’s deployed worldwide for a cleaner, greener, and even brighter future.”
