Nice try at a diversion from your strawman but I will humour your ignorance
It doesn't give any reasons why it is warranted,
Your own strawman here. The question was about wireless. You've just done a switch to justifying the NBN. Naughty!

Classic lie of omission. The full quote is:
Quote:Re DSL technologies - yes, they will continue to get better - mostly
as a consequence of Moore's Law and the ability to throw more
processing capacity at the task of discerning signals against a noisy
background. However, the law of diminishing returns applies ... and
Shannon's Law is ultimately one of limitation, not exponential growth.
Copper will *never* compare to fibre in its capacity, and the key to
better performance lies in shortening copper distances - that is,
pushing fibre deeper into the network.
Quote:the latest VDSL2 chipsets can reliably deliver 80Mbps downstream and 20Mbps upstream over its cabling. That sort of bandwidth will satisfy most people for quite a while into the future.
And again. If you're going to lie, at least choose a different lie. The paragraph following that reads:
Quote:But with our trading partners moving to fibre, applications that
consume higher bandwidth *will* emerge and we will be caught short as
a nation if in the long term we don't have the infrastructure to
compete. I would contend that Australia needs a plan to evolve to
predominantly fibre infrastructure - not necessarily in a short a
timeframe as eight years, but certainly sometime over the next 20
years.
We might be able to delay the expense of the NBN, but not for long.
