Gfast at 360 meters

Andrew managed to get my line added on the DSL checker for gfast (big thanks) and i've had it installed today. I knew I was on the limit and the line is about 70 ish meters longer than I first thought.

Estimate was between 120mbs and 144mbs and I'm syncing at 116mbs down and 13mbs up.

Is this a little low for a 360 ish meter line or about right?

Pretty rubbish indeed. Go back to VDSL if I were u. The upload u lose more than VDSL

That’s the thing isn’t it ..... it nose dives very quickly as it reaches its operational boundries.

Not sure if its worth worrying over 4 Mb/s, ie getting 116 Mb/s instead of 120+. Unless your CP has guaranteed you a minimum speed of 120 Mb/s on gfast and will let you leave penalty free if your line isn't able to achieve that?

I see your upload has decreased from 20 Mb/s on vdsl2 to 13 Mb/s on gfast What were your estimated upload speeds?

I'd say it's good for that line length. G.fast uses only the higher frequencies (to avoid those used by ADSL and VDSL) and those are the ones which suffer the most from attenuation over distance.

Check your contract to see if you have a speed guarantee. Consider how much extra you're paying for G.fast, and whether it's worth it for a small increase in download speed and a loss in upload speed.

The sync speed that you get could change over time based on factors such as temperature and humidity - even on VDSL I find I get 4.5-5Mbps upload in winter and 3.5-4Mbps upload in summer (that's on an estimated 800-900m line length)

It's actually cheaper for me to have upgraded to gfast due to the black friday deal and other discounts on my account.

We estimate your line could support between:

120.1 and 144.2 Mbps download speed
7.0 and 19.3 Mbps upload speed

You should expect a Guaranteed Minimum Download Speed of 100.0 Mbps.

If the drop in upload speed is OK and the extra download speed is good for you then its stay with it.

As for expectations, its in line with what I'd expect

The upload doesn't really bother me too much. The engineer did say this is the longest he has seen it work and he nearly didn't bother even installing it be was suprised by the sync. he said my line is 332 meters to the DP.

Hopefully BT deploy the unused spectrum between VDSL and Gast to get a better range of speeds.

Fair enough, though I imagine most people wouldn't bother upgrading from FTTC 80/20 to G.Fast 116/13, especially if asked to pay extra.

This ^^ 116/13 from 80/20 is not worth the extra cost! If the cost the same as VDSL then it worth it but not worth it because of poor upload speed.
