OK, so it will take 8 years and reach 90% of premises. What happens in
the interim? What happens at the edges?
Could DSL technologies be employed to provide bandwidth higher than
wireless can manage beyond the limits of the fibre, both as it pushes
out and where it eventually stops? I have 9.5 km of copper between my
home and a RIM (see entry dated Monday, 2 February 2004 in
<http://david.boxall.id.au/ISDN.html>). It's possible the fibre that
currently stops at the RIM will be extended to within DSL distance of my
place. Then again, Telstra owns that infrastructure, so maybe not.
What about other fibre that Telstra's installed over the years (see
entry dated Friday, 30 January 2004 at the same URL and entries dated
from 9 August 2003 in <http://david.boxall.id.au/Phone1.html>)? There's
no commercial incentive for Telstra to donate their asset to a network
it won't control. Unless the government's going to commandeer it.
Looks like a lot of infrastructure will be duplicated. That seems a bit
of a waste, but might be the path of least resistance.
Wireless is of limited use in my (mountainous) area. For example, I'm
less that 3 km from a Telstra tower, but 3G (or NextG) service is weak
to none. For my neighbours, 100 metres away, it's reliably none.
