Vectoring to bring step change in speeds in Ireland
Eircom in Ireland is embarking on the massed roll-out of vectoring technology and with 150 of its fibre cabinets running vectoring already and the expectation that this will hit 3,000 by the end of March suggests they are happy with how G.993.5 vectoring works in the real world outside of the test labs.
Total Telecom suggests that with 700,000 homes in the FTTC footprint currently, that around 70% will benefit from a speed boost to offer services in the 70 Mbps to 100 Mbps region.
Ireland has around 1.65 million private homes, so with plans to extend high speed services to 1.4 million premises for 2016, it looks likely that a situation not unlike the UK will arise, i.e. arguments over where the operator has decided to deploy its services and why it is upgrading speeds for those that already can get the faster services.
For those wanting to see what sort of difference vectoring can make, then broadband-forum.org has a technical paper that goes into the technical aspects, but we have extracted one of the graphics that shows the benefits while largest for shorter lines does significantly boost the availability of faster speeds.
The 99% WC graph represents a worst case scenario for Profile 17a VDSL2 in terms of cross-talk, and explains why as take-up increases in areas people may see speeds dropping away. If the real world deployments can double speeds at 900m of telephone wire from the cabinet, then while this will be complained about as sweating the copper assets it is certainly an improvement worth having. 50 Mbps at 900m is significant as it means that 85% of telephones lines connected to a cabinet can get that sort of download speed.
Openreach has been trialing vectoring but it is unclear as to when it might launch or whether the intial trial areas have been expanded.
