The problem is we don’t know what NBNCo wants! Or more importantly what they will allow. Because that will very much decide on how it can be connected in medium sized apartment blocks.
If we look at the Optus/Foxtel example, they simply dictated what they wanted in a ‘take-it-or-leave” manner. No back-bone to their exact standards meant no Foxtel for you. Optus were even harder to deal with.
Our building was just 1 year old when we tried to get Foxtel connected – with the cable just outside our door. We had a brand new TV distribution system, even cables going to any future satellite dishes on the roof.
Foxtel sent their techs and gave it the thumbs down. It didn’t meet their standards. They refused a cable connection and said we had to go satellite. Even then they refused to use out new cabling. We had to run a new back-bone – which we managed to do in a less than perfect way (and we still are not allowed Foxtel IQ). Anything else would have been enormously expensive or ugly.
So I’d want to be pretty sure about what NBNCo will require before doing too much installation. They might end up behaving like Optus/Foxtel and have pretty strict requirements.
