A New Type of Li-Fi Has Reportedly Cracked 40 Gbps, 100 Times Faster Than the Best Wi-Fi

If you’re frustrated with slow wi-fi, you might be one of the many people eagerly awaiting the commercialisation of li-fi (or light-based wi-fi), which promises to be up to 100 times faster than the connections we use today.

Most li-fi systems rely on transmitting data via LED bulbs, which means there are some limitations to how easily the technology could be applied to systems outside the lab. But researchers have come up with a new type of li-fi that uses infrared light instead, and it’s reportedly already cracked 40 gigabits per second (gbps) in early testing.

‘Li-Fi’ – A plan to turn every lightbulb into an ultra-fast alternative to Wi-Fi

Li-Fi doesn’t work in the dark or outdoors, but it only has to be a supplement to existing wireless networks to be valuable.

The more popular wireless networks become the slower they are. Fudan University researchers in Shanghai have just become the latest to demonstrate a technology that transmits data as light instead of radio waves, which gets around the congestion issue and could be ten times faster than traditional Wi-Fi.
