| Yes, but my point is that you can keep milking the copper as long as you want, the technologies to do so are all over the place. The thing is, the people who own the copper are going to use DSL or run fiber at this point.
I just think these stories of achievements are nothing special, this article is just picking and choosing.
Everything over existing copper is "up to" because you cannot predict the quality of the copper. A T1 for example is run over existing copper, it is just repeated every 4,000 feet. You see the round small tub like things mounted on the telephone poles everywhere. A T1 can be stretched a lot farther, but they want to avoid that up to crap and just make sure it works.
And that is why DSL is so limited, quality of copper and why it has to be designed to scale back when needed. All xDSL modems will scale back when the copper is crappy, it has to or it will not work. A good example is heat, on a hot day your DSL speed may actually drop back because of resistance. |
