BT / OR for whatever reason don't seem to fine tune what they already have. I think a good case for OR to stay as it is could be made by BT if they focused on improving current technology.
Everyone who signs up to FTTC is given an individual download estimate but for the same reason that not everyone who has ADSL2+ gets 24MB not everyone with VDSL will get 40 or 80MB (to do with the laws of physics!)
But what makes you think Openreach don't try and improve their existing service?
1. They launched G.INP on Huawei cabinets.
2. They have said they plan to extend this to ECI cabinets once they are happy with the stability of the necessary firmware. Should have they delayed doing it on the Huawei cabinets until then ? (I suggest not)
3. They are trialling vectoring which they see as enabling customers further from the cabinet to get a FTTC service. As their is a cost to rolling this out, I expect to see it in BDUK areas first to boost coverage targets.
Their latest update for VDSL modems on their network includes the need for them to support:
- both G.INP and Vectoring operating together; and that
- modems sync at 1800m and 2400m when vectoring is implemented
which I think gives a fair indication of their plans.
But even if they already fully rolled out all the improvements you mention, it still wouldn't stop the calls for them to be broken up.. nothing would.
On the question of would I pay abit more money for fibre. The short answer is yes.
Most won't which is just one of the many things which makes nationwide FTTP unviable atm
