How fast could BT Infinity go in the long term?

Theoretically how fast could BT Infinity technically go? (That is for residential users with fiber to the cabinet not premises).

There are people who already have maximum attainable rates of over 100Mb.

With a technology called vectoring this will be attainable by considerably more people.

Using the current settings, 17a, with vectoring, theoretically Infinity could do 120Mb Symmetrically, or have 246Mb split between upstream and downstream.

If BT were to increase the bandwidth to profile 30a, which requires regulatory approval, the bandwidth to split between upstream and downstream becomes 417Mb.

Please note that this is with a single copper pair. Nearly all homes have more than one pair, and with 2 physical pairs and a technology called 'phantom' DSL over 750Mb has been achieved at 500m from the cabinet.

So, for the majority of people, if you say 500Mb - 750Mb you're about there.

Thanks for the quick reply. I used to have VM 50mbit and got a nice 53mbit off it at my old house. I have just moved house and am with BT now and get 15mbit off the ADSL which isn't bad compared to what some people get. I really miss the fast cable connection. BT infinity is supposed to come to my area in about 4 months, can't wait for it.

If you are quite a heavy user and like your P2P / newsgroups you may want to consider Sky Fibre Pro. 80Mb/20Mb product with no shaping or caps.

I don't p2p or newsgroup at all. I do max out my connection quite a bit sometimes, for example I have just reinstalled my os and downloading all my games off steam which is circa 300gb. I also upload quite a few photographs being 8mb to 12mb per jpeg, whilst not to taxing doing the odd one or two but when you do a load it takes time.

The current split is 2741 downstream and 1245 upstream tones (not sure why/how there's an overlap) which gives about 164mbps down and 75mbps up, theoretically.
