World-First VDSL2 Demo Gets 500Mbps Data Transfers
pnorth writes "Ericsson has achieved data transfer rates of more than 500Mbps in what it said is the world's first live demonstration of a new VDSL2-based technology. The demonstration achieved data rates of more than 0.5 Gbps over twisted copper pairs using 'vectorized' VDSL2. Vectoring decouples the lines in a cable (from an interference point of view), substantially improving power management, and reduces noise originating from the other copper pairs in the same cable bundle."
Now I know what will be deployed around here 300 years from now. I can't wait.
"I use a Mac because I'm just better than you are."
"Where the technology does have great applications is among Fibre-to-the-Building deployments in commercial areas.
"You might have fibre connected from the DSLAM to the basement of an office building," Goodwin said. "You can then run bonded VDSL2+ up into all the other floors.""
Apparently it's cheaper to roll out fibre to the home these days for new installs and the existing copper to the home is insufficient for last mile where there is fibre to the street (junction)...so looks like it's great for business use or specific regions which fit into some window of installation where they put in redundant copper to the home with fibre to the street.
A fool throws a stone into a well and a thousand sages can not remove it.
FTA: "It showed aggregated rates of above 0.5Gbps at 500 metres, bonding six lines."
So if you happen to have six unused lines lying around and happen to be within half a kilometer of the fiber node and nothing else goes wrong you could get 500Mbps. Realistically you won't be that close to the node, you won't have that many spare lines, and for the sake of a "consistent user experience" (hi AT&T!) you'll get the same craptastic service that someone at least 1km out with at most two pairs would get.
But some PHB will decide to deploy it because his spreadsheet says that FTTH is too expensive, even if it is a one-time expense, and marketing swears that most people can't tell that their upstream is slow and their HDTV channels have been recompressed into mush. The only people who would notice are the ones who'd buy high-end service tiers if they didn't suck...
It will just be throttled.

Around here, cable internet is absolute crap due to all the students sucking the bandwidth dry. I don't care what they claim to provide speed wise, it was always slow. The connection would also just disappear for over an hour at a time most nights around 10PM. DSL doesn't provide the theoretical rates of cable, but what it does provide is a fixed rate and the phone company, as much as they suck, sucks a lot less than the cable company when it comes to reliability.
Well lets go back in time to get a perspective.
We are talking about Average Home use not corporate high end use.
1992 9600bps 3 megs an hour
1994 14.4k became the norm. 6 Megs and hour.
1996 28.8k became the norm. 10 megs an hour (after 14.4k we rarely ever got full speed connection over the modem)
1998 56.6k became the norm. 13/14 megs and hour that much more flaky.
2000 Cable Modem/DSL started to enter the market. In my area peak speed was about 500kbs so about 225 Megs an hour
2002 1mbs
2004 2mbs
2006 4mbs
2008 8mbs
2009 we are at about 10mbs/15mbs (with paying extra for 15mbs)
So roughly we double in speed every 2 years. So I doubt we will see 500mbs for home use until...
2010 16mbs
2012 32mbs
2014 64mbs
2018 128mbs
2020 256mbs
2022 512mbs
2022 Wow. All my predictions are seeming to fall in 2022 lately, Real Time Ray Tracing, Dukenukem forever, Now home use at 500mbs. 2022 will be a cool year.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
VDSLv2 gives you 100mbps. Technically, they would only need 5 lines to reach 500mbps, but I imagine ther "500mbps" is actual throughput, thus the requirement of a 6th line to reach this figure. However, this is with bonding. They could have just as easily claimed 10gbps speeds, by bonding 20 lines. VDSL2 bridges are readily available and bonding isn't anything special. The summary, the article, and the whole press release is just bull.
As for if this is good idea or not, it depends on the distance. This only makes sense for distances between 100m and 300m. Otherwise, there are better options. If your distance is shorter, run Ethernet. If your distance is longer, you're either going to lose performance or consider running fiber.
Not so spread out. Examine a map of population distribution. Note all the white and yellow around the middle and all the blue along the coasts and readjust your math.
It's not as dense as Japan by any means, but upgrading infrastructure is plenty feasible, provided you can dislodge the incumbent interests.
upon the advice of my lawyer, i have no sig at this time
