Not the best advert for G.Fast


[link to this post]
 
Stats for G.Fast have just appeared on the BT DSL checker (https://www.dslchecker.bt.com) for G.Fast at my exchange (Upton Park) but it looks like you need to almost live in the exchange for it to offer speeds above FTTC.

Stats are as follows:

VDSL Range A (Clean) 80 67.9 20 19 59 Available
VDSL Range B (Impacted) 80 55.4 20 17.1 40 Available
G.fast Range A (Clean) 69.6 52.6 12.9 10.1 42.7 Amber
G.fast Range B (Impacted) 45.7 22.4 6.5 3.4 20.8 Amber

Current ADSL stats

ADSL Link Downstream Upstream
Connection Speed 15997 kbps 1022 kbps
Line Attenuation 18.5 db 10.8 db
Noise Margin 8.9 db 9.1 db

Anyone got any idea on what I might get on FTTC?

Thanks

It's actually the distance to the FTTC/G.Fast cabinet that is the crucial parameter. You must be quite close to get those FTTC estimates and should get 80Mbps down, 20Mbps up. The G.Fast figures look poor, I wonder what "Amber" means, not available or a bit rubbish so don't bother.

I'm guessing "Amber" probably means almost set to go but a few bits to be done before it's fully live, those stats should improve hopefully by the time it does so, especially when you're getting top FTTC speeds.

As you are still on ADSL it probably won't have accurate results for G.Fast as they do take into account stats taken periodically from a FTTC connection.

The faster it goes, the less far it travels. The sharper the ‘drop off’ speed wise .....

Get to around 300m from the cab and there would be no point at all.

I agree, but to get those FTTC estimates the OP must be virtually next to the FTTC cab so why are the G.Fast figures so low?

Probably the usual story ... inaccurate checker.

you get 15 Mb/s on ADSL? if i could get that speed i would have stayed with ADSL, cheaper than fibre and would do for me.

Min 67.9/19 Max 80/20 only way to know for sure is to put your info into bt.com and find out what the guaranteed speed is. I agree with the others, G.fast is not worth it for you

If I never had FTTP and had to fall back to FTTC and then added G.Fast on my cabinet it wouldn't be worth it either going by the FTTC stats of my cabinet shown below:

I removed the non important info like ADSL and the far right side info.

We are about 470.85m from our cabinet going the route our cables are routed, hence the low FTTC Speeds.
So assuming they added G.Fast the speed for it would be a lot slower than what we would of got via FTTC.

The way I see it, they should be working on ways to increase the speeds of lines that are slow, not to increase speeds of lines close to the cabinet that may already have a good speed.
