Interesting video. This video must sent to to the government of UK and BT Openreach to learn from this lesson!
You'll find that a lot of countries are very interested in Openreach's brownfield deployment of FTTP, such to the extent that a number of teams have been out to the Middle East on a number of occasions to demonstrate their deployment.
If Openreach could financially deploy FTTP to every single house, flat, building, business, they would. The problem is it is just not financially viable for them to do so.
