basically there is noise still in the lines but this clever chap has a ma thematical model to reduce the interference
BT wont have any excuses soon, lol
I have my doubts. Even without any interferance in a test enviroment, copper as a material is absolutely terrible for supporting high frequency electrical signals. (No I dont mean bandwidth). Well I say terrible, but in comparrison to what is out there being used today as part of network backbones.
Though from reading that article I guess hes changed what is being sent in the channels at the current frequency range. The techincal mathematics behind it I dont understand.
Getting copper to support both POTS line and as an ADSL by seperating the frequency spectrums was a technical achievement. But really we should be moving getting on with nagging BT to pull the finger out and catch up with the rest of Europe, IE fibre optic. Not bodge jobbing an age old infrastructure.
In short....move on.
Your right it is horrible and we should all be on fibre by now or asap tbh But still Lazy BT may see this as an option and if it means getting just up to 50mbps for example and just software and a bit more hardware in exchanges then it would be a quick upgrade and its BT here so they will probably take it if it is available
Fibre, GREAT idea with BT. Get fibre, and forget about broadband form anyone but BT. They arent allowing 3rd parties to add their hardware at the moment, and IIRC you can;t get over 8Mb with FO because thye are being c***s. Thats an obscene joke by any standards.
It gives hope! has much hope one can get with BT at the helm!
TBH my parents would settle for 1Mb. 768K is all their line will do. This doesnt bother them much, but its a PITA for downloading linux distros.

Google BT and 21CN or 21st Century Network.
Fibre is already being rolled out nationwide. Cardiff will be the first to have it.
