From the earliest days of the internet, the one thing we’ve always complained about is slow connection speeds. But now, there’s a new technology that promises internet connectivity that’s cheaper, more secure and crucially, a hundred times faster than broadband. Known as Li-Fi, it uses light waves emitted by LED light bulbs. (Illuminating, Tim).
Developed by German physicist Harald Hass, Li-Fi transmits data via flickering light beams from an LED bulb. These fluctuations are detected by a solar panel connected to a computer which acts as a receiver.
Estonian tech company Velmini is the first to test the technology in the real world. It’s reporting data transmission rates of 1 gigabit per second (Gbps), but under lab conditions recorded speeds have been as high as 224 Gbps.
The agonising wait for web pages to load is over. We have seen the light.
