Same problems as before; there isn't enough wireless bandwith. Just the
same as the startrek teleporter being physically impossible.

There's this line
"Today, DIDO can handle 10 users with 10 DIDO access points working and
they are working “extremely well,”"
I think it will turn out not to be a coincidence that the number of
users equals the number of access points.
For example, with two access points, and two users, it's possible to
transmit two superimposed signals in such a way that where one of the
users is located, one of the signals cancels out by interference, and
where the other user is located, the other signal cancels out. That
would completely determine what was transmitted from each access point.
So it would not be possible to add a third user, because there would be
no scope for modifying the transmitted signals so as to make the signals
intended for the first two users both cancel out where the third user is
located. For that, you'd have to add another access point.

A few years back (I think "super G" had just come in)
I helped set a mate up in a small business selling
his expensive telstra (?) service to people in outlying regions around
Ballarat via wifi and some big panel antennas. He was certainly flooded with
interest at the time. Of course, "flooded" is a relative term.
I think he ended up signing a 100-200 customers at $10-20 a month.

Maybe that's because the Republicans come from more rural states that haven't
had any warming, man-made or otherwise.

let's be realistic here:
Wireless has it's place. Lots of people like having a mobile solution to
internet access. Wireless works for them (most of the time, when things are
not too congested). For others, a wired (or fibre) solution works best.
As for speed, face it: According to Nyquist, fibre can, theoretically,
manage around 150Tb/s. Wireless is quite long way behind that. When it's not
too congested. The best thing about fibre is that redundancy is dirt cheap.
Redundancy for wireless is horrendously expensive.
