For a good line and where the take-up of fibre broadband is relatively low, we believe that these estimates are conservative so you may be able to achieve higher speeds up to the maximum of 80 Mbps. Sadly, this issue can result in significant declines in broadband speeds as the penetration of fibre broadband increases. What is particularly frustrating about crosstalk is the fact that it is essentially impossible to predict the extent to which a particular broadband user will suffer degraded performance.

This is because the level of crosstalk interference depends on the position of the pairs carrying VDSL2 signals with respect to one another.

So, one broadband user could experience significant degradation whereas another could be unaffected. This makes accurate predictions of broadband speeds impossible. The only thing that is certain is reduced speeds from crosstalk will become more significant as the penetration of fibre broadband increases. FTTC service rely on copper cables to carry broadband signals between premises and the street cabinet and these signals are susceptible to:. Crosstalk introduces a degree of uncertainty in speeds since some copper cables may be subject to increased interference from other cables.

Without vectoring, VDSL2 has the potential of delivering Mbps speeds but not at any practical distance from the street cabinet. Currently, BT limits the maximum connection speed to 80 Mbps as very few would be able to benefit from higher speeds without vectoring.

The short answer is not with current technology. However there is a lot of research work going on to increase FTTC capacity, with standards such as G.

Fast which promises to deliver speeds of to Mbps being trialled in the lab. Whether this performance translates to the real world is yet to be seen, particularly as high speeds are only achievable over relatively short distances.

In contrast, FTTH networks obviously have the capacity to carry this growth in traffic now, providing comparatively unlimited bandwidth that scales for the future. In the US, Far East and other parts of Europe, more and more FTTH networks are being deployed, creating gigabit cities where everyone has access to high speed broadband, with a huge impact on the economy, public services and the daily lives of citizens.
