Scientists Explore A Light Bulb-Based Based 10Gbps Li-Fi/5G Home Network (ispreview.co.uk) 12

Mark.JUK writes: Researchers at Brunel University in London have begun to develop a new 10 Gbps home wireless network using both Li-Fi (light fidelity) and 5G based mmWave technology, which will fit inside LED (light-emitting diode) light bulbs on your ceiling.

In simple terms, the Visible Light Communication (VLC) based Li-Fi technology works by flicking a LED light off and on thousands of times a second (by altering the length of the flickers you can introduce digital communications).

The article says it'd be more energy efficient (and faster) than a standard Wi-Fi network -- though both technologies have trouble penetrating walls, so "you'd have to buy lots of pricey new bulbs in order to cover your home..."

"It's probably not something that an ordinary home owner would want to install; unless you're happy with running lots of optical fibre cable around your various light fittings."
