Li-Fi is still a long way from being used commercially, but by way of illustration, using a 224Gbps speed would technically allow for 18 movies of 1.5GB each to be downloaded in a single second.

so it's through light? the nsa knows it, but didn't want to release it, because they prefer us to be exposed to emf from wifi... to have an edge over our children, they must destroy us and their mothers using all the tools of stealth warfare. Answer TW.

 so we would need to replace all lightbulbs with modified ones, and entire circuit from router to lightbulb to provide it with internet connection ? seams pretty impractical, or would the wifi signal go to bulb, and then be re-broadcasted through the bulb. Its amazing what they did, but i doubt we will see tech like this anytime soon in our houses.
Regarding the current issues with wifi, if ure scared of emf, just place cables to your computers, and eliminate need for wireless connection..

cheers

Camrips, evidently.


I remember about a decade ago there had been much ado about transmitting data through existing electrical networks. What happened to that technology, who knows? Didn't hear anything about it ever since.

Time for the FCC to tax LEDs as unfair too fast internet connection. Net neutrality needs to slow this down  for everyone...

Do you mean Power-line comm (http://en.wikipedia.org/wiki/Power-line_communication) technology? Here in Italy he's used by former electric monopoly to compete as an ISP against Telcos in some parts of the country. Also, AFAIK is deployed in some Home networks to avoid laying LAN cables while integrating Wi-Fi networks. Domotics applications also seems to use it.

And movie makers should have their share of the pie, obviously.


Yes, at that time this technology had been endowed with great prospects as the future of home networking ("Ethernet over power").

HomePlug. I know some people who didn't want to bother with laying cables and opted for it.
There are quite a lot of products in that category (https://www.komplett.no/search?bn=10273&category=10273_Nettverksprodukter&q=*%3A*&subcategory=10292_HomePlug%2FPowerline)

My guess is LiFi will be as common in homes as WiFi is in half the time it took WiFi. There is a great potential for a hybrid of WiFi and LiFI.

Such an hybrid network would require improved Wi-Fi set also; otherwise, You have a bandwith bottleneck due to the lower bandwith of Wi-Fi.

Even if you improve your wi-fi you'll need a faster network card in your pc. Even if you have a faster internet card you'll need a faster hard drive to deal with so much stuff to save.

 

That technology is in use. You can buy LAN adapters, but ISPs are not using (or rarely using) this technology. I guess the telco companies made some agrements with the utility providers.

Never heard of Li-Fi but 228 Gbps is insane. 18 movies in a second  :o

Why is Li-Fi considered greener in Wi-Fi?

HURRAY! It's about time someone came up with a solution to slow ass signals for the internet! It would absolutely be fantastic to not be limited by where you live etc. if you wanted to get a fast internet connection, hell, this kind of thing could make travelling fun. I take it Li-fi is similar to fibre optic where it uses light instead of electricity to send data? I don't know too much about this kind of technology.

I remember working on a project on it in university. Its definitely the future of connecting

I remember reading an article about this a while back, it's promising tech for sure. From what I remember the only downside is that as soon as the light beam is interrupted by any obstacle, like a wall for instance, you lose connection. It's definitely been over a year since I first came across this tech, hopefully they gonna figure out a way to implement it soon.

Why not then place a li-fi to wi-fi transmitter right into the bulb? Do I miss something, or will it just kill the whole idea behind this li-fi?

I think the limitation would be that it always has to be in direct site/line of view. Else it will fail. Does seem like a big limitation.

Don't be too excited. BT can surely slow down even light itself :).

Oh please, everyone know that's Virgin, they're capable of affecting ping for no reason.

It is easy to understand how data could be transmitted from a strong light source to a device in a room. How is data going to be transmitted from the slave device to the master? The room is likely to be filled with ambient light? They might be using invisible light spectrum for the return channel.

The usefulness of this Li-Fi is very limited. We need a clear line of sight, so devices are cannot connect when they are in bags and pockets. The only breakthrough I can see is fixing them on all street lamps and everyone gets free Li-Fi.

Well, Virgin is quite far from beeing perfect but since I moved out of Virgin service areas and have to use BT I'm often dreaming about the good old days with Virgin :). That was a real golden age, with amore or less working router and with a bit less stupid support :).

Nobody would need the Pirate Bay anymore. Movie companies would have to start charging in advance to make movies.
