Wi-Fi alternative Li-Fi proves to be 100 times faster

The Wi-Fi alternative tech, Li-Fi, has finally been tested in a real world setting, where it was reportedly able to send data at speeds 100 times faster than current Wi-Fi tech.

According to IBTimes, Estonian startup Velmenni, which has developed smart LED bulbs that can implement Li-Fi tech, is testing the tech in offices and industrial settings.

 

During pilots tests, Velmeni was able to send data through the Li-Fi touting light bulbs at up to 1GBps, which basically equates to downloading a HD film in a just seconds, according to the report.

"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light," Deepak Solanki, CEO of Velmenni, told the publication.

"We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the internet in their office space."

Lights for speed

Invented by Professor Harald Haas from the University of Edinburgh, Li-Fi, or light fidelity, transfers data over the visual spectrum rather than via radio waves.

It uses light bulbs that flash on and off exceptionally quickly, sending binary information to a recipient.

The fastest speed on record for the tech in a lab setting had been 3Gbit/s during the development of the tech, but two years ago, researchers began using specially developed LED bulbs that could separat the light into parallel streams, to triple the speed.

While these speeds are impressive in a lab setting, until now, results of Li-Fi tech in a real in a real world setting hasn't been really revealed.

Haas believes Li-Fi could eventually be used to power a future generation of network in conjunction with Wi-Fi, providing more consistent coverage within buildings, as well as making for a potentially more secure network as Li-Fi can penetrate walls.

 

Yikes.

Imagine the information age when speeds are at 3GB per second.  And this will be soon.  In the coming decades one could absorb all the information ever recorded in human history in minutes.  But we're going to blow it all on super-realistic virtual porn or something.

I will definitely be blowing it all on something whenever I have access to super-realistic virtual porn... a lot.

Is it too much to ask for both?

I don't pretend to be an expert in the field, but the bolded confuses me.  We're dealing with lights here, and presumably low-energy lights.  I wonder how it will go through walls, and if it does, how it would be secure, since how would the signal be protected from unwarranted access.  My initial thought is you would need line-of-sight to the router, which would make it more secure, but obviously would mean walls were an issue.

Interesting news, although the tech jump doesn't surprise me.  Media quality will expand to fill the bandwidth, as it has always done.  And that's a good thing too.

Walls are an issue and it has to be within line of sight to the router but they argue that since this is the case that it will be more secure than the wireless data now. I believe that in terms of practicality they will likely make some sort of hybrid wi/li-fi rather than completely substituting wifi altogether.

Is it also going to be 100x cancer inducing?

Since it's just light I seriously doubt it unless they are using UV rays to transmit the data then I suppose the risk of skin cancer may slightly increase.

We don't need it.

There were those that said we didn't need the power loom or printing press, the telescope or television... the interwebs... progress has always, throughout time, faced this exact opposition.

No it ain't.  We have to wait for things that are digitized.  Wait times for that should be near zero.  We have better things to do.

Therein lies the crux of the problem. The speed will never be good enough because the incessant need to have things faster.

I meant we don't NEED faster internet. The current speed of internet access is acceptable.

Really depends on what the future brings. Do we need it now? Maybe not. Will we need it in the future as technology progresses? Quite possible.

I believe this need predated the interwebs, but i think Kragar noted something important, the quality of media will merely increase to fill the bandwidth.  But to get all this cool new digital stuff we'll need faster and faster speeds, more and more storage.

Faster, or more efficient, or cheaper to produce.  Innovation comes in many forms, and spawns further innovation.

What exactly is the "problem"?
