Re: BT Infinity and line length


[re: allofus] [link to this post]
 
allofus -
"The BT Openreach engineer said that BT Infinity which uses VDSL2 performance drops off dramatically (like a cliff were his words) when the copper line length exceeds around 300Mts."
- either you misheard him or he is talking out of his comglomeration point... Infinity uses VDSL which does not 'drop off a cliff' at 300m like what VDSL2 does. It fades gently to oblivion around 1500m

No, Infinity uses VDSL2

Ok - my mistake, but he was still wrong about 300m was he not?

he shoudl get some ulpft up to around 1.4 - 1.5km depending on his line quality of line and local conditions and distance from DP to premise

Perhaps you didn't notice this is the BT Broadband forum.

Post codes can be a bit coarse. In my case the centre of the postcode area (according to Google) is 250 metres closer to the cabinet. In addition, there's the distortion caused by those on capped packages, either by capped sync speed or by throughput (as happens on some offerings). Unless compensated for, they will skew the results.

Oops. I didn't read the question properly. In that case, the right answer is that using VDSL2 doesn't decrease reach, it just increases the speed for shorter reach lines (a little bit simplified of course, as the profile and power masking also factors in).

Judging by my (approx) 650-700m line, then I think your stats are pretty well in line with what I'd expect apart from upload, but you've explained why.

And I can get an 18+ upload if I changer router. Max attainable UP 23Mbps

An earlier set of result before the restriction: http://www.thinkbroadband.com/speedtest/button/13919...
