VDSL Vectoring still in the smoke and mirrors phase

Vectoring has the potential to boost speeds for VDSL services, by helping to mitigate the crosstalk that the higher frequencies of VDSL use. Alas while there have been numerous press releases around the world from manufacturers the reality may be that the UK position of trials in a handful of locations reflects accurately what is going on elsewhere.

Dave Burstein of DSL Prime who watches the world broadband news sums the situation up nicely with 'Vectoring: too much hype, but very close'. The figures are such that Alcatel has shipped 1 million lines and Huawei 1.2 million, but in actual fact almost none of these are turned on, with the few tens of thousands running actually being used for debugging systems.

In the UK if vectoring and other tweaks were to allow a retail provider like BT Retail to show that 10% of its customers can get above 120 Mbps, then the speed war with Virgin Media may be re-ignited. For those users generating content, or simply making use of cloud services for photo backup, the current FTTC services already beat Virgin Media by a long way.


isnt this a load of rubbish anyway - if tweaking gets bt retail to improve their speed - the asa will need to clamp down on misleading advertising - curerently 10% threshold and your allowed to advertise this speed - virgin exceed this by 5-9 times this threshold regardless of any traffic management -which if came to would probably be dropped once full modification of their dsl network onto same infrastructure is carried out.

I'm sure there's a sentence in all those words trying to make itself known to readers, but I'll be damned if I can work out what your point is.

All the equipment manufacturers are still attending interworking plugfests for vectoring, ironing out compatibility issues.

That means any live equipment needs to be in tightly-controlled trials, with modems known to be compatible. No public availability, for sure.

But the hype isn't surprising. The kind of change that could come from this is like inventing DSL in the first place. It adds another decade or two onto the life-expectancy of copper - and that is worth a bob or two.

"I'm sure there's a sentence in all those words trying to make itself known"

Hahaha, yes, exactly what I was thinking. Did that whole item actually mean anything??

I can't believe the money they're wasting on HS2. Imagine if it was spent on FTTH for all. Governments are so fecking stupid!

@ahockings: Totally agree, vectoring is more of a dream than reality. And of course WWWombat still believes in its goodness, just as he thinks that VDSL copper is the non-plus ultra, and that there is no money for a proper FTTP rollout.

Evening to you too Juergen

I don't think @ahockings states anything about vectoring there. You're inventing things to agree with.

And inventing the English language too - like the first comment. What is "non-plus ultra"?

Money is indeed the thing stopping an FTTP rollout, it ain't a technology hold-up. BT can't get the money off investors; their competitors can't afford it; the government don't have it either, but most of all - the public won't part with it. They want to spend £2 on Tesco, or £6 at TalkTalk.

Don't rage at me. Rage at Tesco & TalkTalk.

And no point in talking about various european countries that have large FTTH/B, because the level of subsidy or use of government owned infrastructure is major factor. Or more pertinently, they were building residential fibre networks a decade before OFCOM allowed BT to.
