ISP WarwickNet first to deploy Vectoring on FTTC broadband

Friday, June 12th 2015

WarwickNet, the business ISP, has become the first internet service provider in UK to commercially deploy the VDSL2 Vectoring technology (ITU-T G.993.5). This technology improves performance by reducing crosstalk and interferences, on their superfast broadband lines (on FTTC).


Normally FTTC lines and their VDSL component have a problem. Owing to the heavy traffic on a busy cabinet, the copper lines can begin to cause interference for one another and thus reduces service speeds. This problem is solved by Vectoring (self- FEXT cancellation) solution. This tech works like a noise cancellation system like in headphones. It coordinates the line signals to remove most of the unwanted interference.


WarwickNet appears now to have overtaken BT to deploy this technology first, although BT had trialled this solution for almost 2 years, but is yet to deploy it commercially. On the other hand, WarwickNet hopes to gain an edge over BT and beat other FTTC based ISPs, to become first to deploy the technology. The solution helps the ISP to deliver over FTTC lines, download speeds of up to 100 Mbps and up to 40Mbps of upload speeds.


WarwickNet has built a number of FTTC street-cabinets across the county. Comparatively, the challenge of deploying Vectoring over a small number of Sub – Looped Unbundled (SLU) FTTC cabinets is less complex than that on a national scale, which is the difficulty BT faces. Recently, BT had taken some time to resolve the problems in their recent upgrade to G.INP, which is somewhat complementary to Vectoring. This experience may be a deterrent to their deploying Vectoring immediately.
