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.
For those who missed the li-fi hype, the communications system was first invented in 2011, based on the idea of transmitting data via the imperceptible flickering of LED light - think morse code happening so fast, it's invisible to the human eye.
Lab-based tests have shown that this type of li-fi can achieve speeds of 224 gbps. In real-world testing back in 2015, that speed was slowed down to a still-impressive 1 gbps, getting people excited about the possibility of li-fi in their homes and offices - all you need is an LED bulb.
But there are some challenges with LED-based li-fi. Obviously, the fact that it requires a light to be turned on in order to work means you can forget lying in bed in the dark and scrolling through Facebook at breakneck download speeds). And just like regular wi-fi, existing LED li-fi systems use one bulb to beam data to all connected devices, so it slows down the more devices that are connected to it
