A group of scientists in China have invented the world's first lightbulb that emits its own wifi signal.

Researchers at Fudan University in Shanghai, have developed a prototype for the new technology, which they have aptly named Li-Fi.

Experts claim the micro-chipped LED bulb works even better than the average wireless internet connection in China.

As many as four devices near the lightbulb can connect to its signal using light frequencies rather than radio waves, according to Gizmodo.

The bulb itself is embedded with a microchip that produces its signal, which at 150 megabites per second, is considerably faster than the average wifi connection in the country.

Next month researchers will unveil 10 sample lightbulbs and their accompanying kits at the International Industry Fair in Shanghai next month.

Experts suggest that this faster, cheaper and more energy efficient way of connecting to the internet could become common practice in Chinese homes, where more and more people are abandoning traditional lightbulbs in favour of LEDs.

I don't know about this. This would mean you'd have to implement protocols in each and every lightbulb? I also can't imagine this being cheaper than wired Internet.

faster, cheaper, more energy efficient...

all i see is an incapability to be used through walls and susceptibility to interference from other light

Standard wifi frequencies also have susceptibility to interference, I wouldn't think there would be a problem there.

But yeah, I'd imagine there would be huge problems with the properties of light, like you mentioned not being able to go through/around obstacles.

yes, but standard wifi uses frequencies that are uncommon for other things to use (unlike light, which the sun sort of uses the same frequency)

Standard WiFi uses 2.4ghz just like microwaves, RC-cars and other gadgets. Its a very common frequency.

This seems to be a popular topic according to the stats. I wonder if something has advanced in this or something has been posted on the Internets about it.
