Copper Tech

Ericsson recently did what few thought was possible. The guys (and gals) at Ericsson have successfully tested some new technologies that will ultimately allow copper wire to transmit data at speeds of up to 500 Mega bits per second (Mbps). Yes, that is two zeros.

What is even more surprising is that this is a form of DSL technology. DSL, usually much slower than cable and even more slower than the new fiber optic networks being laid down, can become a wave of change when this technology hits manufacturers and internet providers. To accomplish this, Ericsson used a technology called VDSL2 or Vectorized DSL2. In more layman's terms, it is also called crosstalk cancellation. (That didn't help me out either)

What VDSL2 or Crosstalk Cancellation means is the interference and data loss usually associated with copper wire is removed or taken out of the equation. What you end up with is pure data without any interference. This means that the bandwidth usually taken up by the noise and interference can now be used to transmit more data.

I think its best if we don't delve into the technicalities of the matter.


Here is a video to better understand bandwidth.

Either way, be sure to expect much higher bandwidth in the not so distant future.
