Seeing as its come up anyway…
I think BT are trialling a new product, basically you will be able to pay for a fibre to your premises. It will be expensive, but if you are considering satellite there is a possibility it could be affortable.
I think under *ALL* circumstances, if you have a phone line to the house, you can always buy a ‘dedicated’ line to be installed and use that for broadband, and you get a guaranteed speed. perhaps you need to look into ‘business’ options from BT and other phone providers (
Not that I know of, the only products I know of are two linked ISDN lines at 64kb each (compared to the maximum 56kb on a normal phone line), twinned up they will give an connection speed of 128kbs. (slow)
Business products will be provided over fibre if the copper can’t support a decent broadband speed, and you would pay for a dedicated 10 or 100mb connection (or lots more if you can afford it), no contention ratio but you would be looking at thousands in line rental, and if you are out in the sticks, thousands more for installation costs. This is the part of BT that I work for.
