It's a reasonable design choice. Probably the one I'd make as it's a can
of worms for little benefit.
There's not much uncompressed data by

Totally agree.
There is a room in the NBN offices in North Sydney.
It shows a number of different solutions.
The first is fibre to the premises. I

The idea that some places "just can't be reached by fibre" is just plain

I'm old enough to remember party lines and overhead wires across
paddocks. We ended up with underground copper in some pretty remote parts.
Where there's copper, why can

I'm pretty sure (but not actually sure) that that's wrong. Or maybe
half-wrong.
The original plan was to use 2.3GHz+, but that didn't pass the giggle

when the wifi gets congested, though, congestion-related latency will
cause it to
