The world will
probably never stop searching for faster Internet
connections. That drive is what pushed us from the modems of old to the
place where we are today: a place that involves broadband Internet via
DSL, cable, fiber optics, and satellites. But of course, fast is never
really fast enough, and while the bigger push today is getting basic
broadband services to rural communities, the race for more speed is
always ongoing in the background.
But it's not always brand new
technology delivering new speed records. Some companies are striving to
make more out of what we already have, which is a very cost effective
method compared to building out entirely new networks. Nokia Siemens
Networks is one of those companies, and today they have announced a new
technology that could drastically increase the data carrying capacity of
standard copper wires.
The company achieved data transmission speeds of 825 megabits per
second (Mbps) over 400 meters of bonded copper lines and 750 Mbps over
500 meters. Most DSL services available to consumers now top out at
30Mbps or 40Mbps, with some "extreme" cable services going as high as
100Mbps. But these rates are much, much higher, and they use the same
copper technology that is already widely available.
Networks used circuits that involve the creation of a virtual - or
’phantom’ - channel to supplement the two physical wires that are the
standard configuration for copper transmission lines. The approach,
known as Phantom DSL, is being showcased this week, and could hopefully
be used in a real world application in the future. The company has yet
to mention a time line for that, but the fact that it's being
demonstrated to the public is a great sign. We'd gladly take DSL at
those speeds, wouldn't you?

Nokia Siemens Networks has successfully tested a technology that
could drastically increase the data carrying capacity of standard copper
wires. The company achieved data transmission speeds of 825 megabits
per second (Mbps) over 400 meters of bonded copper lines and 750 Mbps
over 500 meters. At these speeds, network operators could optimize
existing, widely deployed copper infrastructure to provide
bandwidth-intensive services for years to come.
Nokia Siemens Networks used circuits that involve the creation of a

that are the standard configuration for copper transmission lines. The
approach, known as Phantom DSL is also being showcased during Broadband
World Forum 2010 in Paris,
October 26 - 28.
“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,” said Eduard Scheiterer, head of
broadband access business line, Nokia Siemens Networks. “However, the
innovative use of technologies such as phantom circuits helps operators
provide an efficient last mile connectivity with existing copper wires.”
Phantom DSL promises a bandwidth increase of 50-75% over existing
bonded copper lines. This prolongs the life of copper networks, delaying
the need for fiber rollout and protecting operator’s existing capital
investments. The promised high speeds will enable a whole new range of
end-user services and open up new revenue opportunities for operators.
The technology could be used to test initial demand for very high
Nokia Siemens Networks’ Phantom DSL will become an integral part of
the company’s DSLAM* products hiX 562x/3x.
