also @ TechSpot: Apple's iOS 7 to be "black, white and flat all over"
NSN manages to pull off the feat by creating phantom (virtual) channels that "supplement the two physical wires that are the standard configuration for copper transmission lines." First shown off by Alcatel-Lucent's Bell Labs in April 2010, the approach is called Phantom DSL and can boost bandwidth between 50 to 75 percent over existing bonded copper lines. "Laying down new optical fiber to the home remains costly, though it is capable of delivering very high speeds and is a definite solution for long-term bandwidth requirements,” Eduard Scheiterer, NSN's head of broadband access business line, said in a statement. "However, the innovative use of technologies such as phantom circuits helps operators provide an efficient last mile connectivity with existing copper wires."
It is quite surprising to see DSL technologies based on copper wiring staying competitive with cable broadband and fiber. Upgrades in DSL speeds are coming at a useful time: DSL has started to lose market momentum, and carriers don't want to just drop it after all the money they've already invested. While fiber networks are better in the long run, most phone companies need to squeeze out more from their copper networks without losing too much ground to cable broadband rivals as the world shifts to wireless networks. That being said, these new DSL technologies are still in the labs and may not work very well over long distances, not to mention all the other technical restrictions. Somehow we doubt you'll ever get 800Mbps at home, from DSL anyway.

Got something to say? Post a comment-
Ha.. and I just switched to AT&T's 3mbps for 14.95 a mo.(for first year) I wonder how much it will cost to get 875mbps?

500 meter is too short in most cities
500 meter to the phone/dsl company is way too short
( Seriousley dude, DSL/copper phone systems have high bandwidth distribution "hubs" all over the city. It doesn't all just originate from one single area!
Also at the moment normal DSL systems work at 2-10mb/s, if that could be upped to 20-30mb/s using this tech that would be a massive boost to overall infrastructure speeds. At that rate the distance would also be MUCH larger than just 400m
Don't stare yourself blind at the 825mb/s and think practical. I think this is great news for older cities that struggle to get fibre lines rolled out.
-
thats a nice theoretical maximum but realistically we would get less than half of that commercially.
-
I already profit from a 50mbps connection. Profiting by more sounds good even though I don't think it'll happen too soon. -
Very nice! Cable Internet companies practice of sharing bandwidth amongst neighbors may allow this new, faster form of DSL to thrive.
I can't help but wonder if land line phone companies will then further explore devices which use DSL lines for video/ audio calling. That is one niche calling market that cell-phones do not yet have an edge.

All these morons saying oh that's great if i lived 20 feet from the server need to realize it says 50-75% speed increase. So that's increase over whatever junk speed you have now if its 20mbit it might be 30-35mbit or more.
-
800mbps is a dream come true in India. Where we are still struggling to get even 1mbps connection you guys are talking about 800mbps. Our download truly su**s. I dont know when a revolution will come into place here
-
I think its more than probable to have such speeds over a single wire, or even more than 800mbit. Its possible to boost wireless speeds but you have to install fiber to boost wired ones?
-
That is quite awesome, but... 825 over 400 meters, and already down at 750 over 500? (or have i gotten it wrong?) Isn't that a bit useless?
-
I'm pretty sure just as with the internal components of a computer, the internet can only go as fast in a 2 way link as the slowest component or connection.

The problem is always between distances and speed. We need to find a technology where speed won't be affected by distances but this is hard to find since we are limited to the materials already installed. Wipe all these copper cables and turn it into optical fiber. We could pass everything through the fiber - radio, tv, internet, phone... without affecting the speed/distance

And currently fiber is the only medium we have that doesn't have a (major) speed over distance issue. With cable internet the number of connections between you and the hub changes speeds and with DSL pure distance changes the speeds.
But a fiber installation is extremely expensive. To install a fiber connection in my area to one building where the fiber is already at the street level costs almost $2000. To run fiber under one city street costs over $10,000. Upgrading and replacing all phone and cable lines with fiber for even one city costs millions of dollars. Now expand that to the entire infrastructure across a state, now the country, now the world.
Good luck.
It's a lofty goal, but not one likely to be achieved in our lifetimes. On top of simple costs you run into legal and political problems trying to do a project of that nature. Depending on the right of way clauses written into property titles, some specify exactly what may be done with the right of way easement. Others do not. It takes a team of lawyers to figure out the answers to just that one question but it must be answered for every property your line passes through. If the title specifies certain things but not fiber optic cabling then you're stuck, you need to take the people to court to get it added or permission to pass the cabling through their land. Now add to it cities and counties that have passed their own laws and restrictions on cabling, right of ways, infrastructure upgrades of any kind, etc, etc.
This is the exact problem the company I work for now is in. We want a direct fiber link from point a to point b. The city where point a is has a contract with another company to provide the fiber optic connections in and out of the city. On top of that the land we want to run the fiber through is county land and they will not provide a permit to add fiber optic cables in that area. So currently point a runs entirely on one fiber link and every time it gets cut the entire city loses all phone, internet, even cell service. But we can't get in there to provide our own backup fiber link, so everyone is stuck.

i guess nokia is not the provider of dsl no?
