dido

I wouldn't put money on it.

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

No.

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.

No , but it will offer a viable alternative at reasonable cost

How would wifi cover remote areas? It won't, of course.

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.

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.

I very much doubt it. Have a look at this critique:
