Re: DSL Checker - G.Fast


[re: WWWombat] [link to this post]
 
Also considering on FTTPoD the 30mbit upstream speed is what everyone gets, whilst on g.fast congestion is automatically a lesser isue as various lines will have lower than 30mbit estimates, on kitz someone posted an estimate where the DS speed range was about 95-136 (not impressive) but the eye opener was that on the upstream the same line had 20 20 estimate for VDSL but less for g.fast.

A reminder that BT are currently running on early hardware, and estimates will use data appropriate to that. They need amendment 2 hardware before they can get close to their target ranges, so it is (slightly) pointless looking at actual speed estimates yet. Fun, but pointless.

And for G.Fast, the relative proportion of upstream to downstream can be altered on the fly. If they find the upstream is dropping away faster, they can alter it.

Relative proportion switching on a pod basis or per line basis?

lots of ifs and buts, we can only judge on what is actually happening now.

e.g. VDSL would be much better if only vectoring was deployed, but it is not.

There is no certainty existing equipment would be replaced and BT's history shows they dont like replacing stuff with a short life, instead they like to sweat it.

So what is more likely is the equipment that is deployed will stay as it is and if newer generation equipment becomes available that will be deployed to newer areas. Although granted these are only limited trial areas so may not be subject to normal rollout procedures, they may replace these as there is only very limited amounts deployed.

G.fast as with many other things is benefiting from the increased levels of processing power, and it is conceivable that more of the upgrades are software based these days e.g. improvements in how the vectoring operates and since G.fast had vectoring embedded from day 1 one would have a reasonable expectation that improvements that will a shift from vectoring 48 ports to 96 ports will be software based.

And the commercial reason for replacing them all is?

What was the commercial reason for installing them in the first place?
