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.
