54 mbs that's brilliant, all we get is 47kbs ffs.BT spouting on about this new Infinity service, what they really should be doing is updating all of their old exchanges. But will they? Well i'm not going to hold my breath on that one.
Rant over
Part of your problem here is the way BT is split up. In a way it's easier to think of them as a couple of separate companies. Open Reach maintain all the wiring between your house and the exchange.
BT Retail (the people you pay for your broadband services etc.) merely send your services along that wire.
For BT Infinity to work, the dodgy copper wiring that serves your house is ripped up from the exchange to the cabinet (the green thing you see kids loitering on) and replace it with a fibre optic cable. This is great for sending data around the place, but when you consider that you can have 10,000+ homes on a local exchange, and hundreds of street cabinets, you can see that the costs are going to get pretty high pretty quickly.
BT Retail have no real direct bearing on 'making' Open Reach do this. They will need to give that division the cash to perform the work. Where's that cash coming from?
On top of this, fibre isn't the be all and end all. If it went all the way to your house it would be, but it won't. It goes to your local cabinet, and from then on you still have the dodgy old copper that was installed when your house was built/added to the phone network.
So you can still be affected by distance of the wire between the cabinet to your house, quality of the wire, outside interference etc. etc. If you look closely at the BT Infinity literature you'll see the words "up to" 40mb. That's because until they switch you on they won't know for sure what speeds you can achieve. If the line between the cabinet and your house was crap before the upgrade, it will still be a crap internet service. Just the way these things work.
Now Asia... they have it right... just went straight to fibre. Must be bliss.
