It's hard to say how Super WiFi will shape up but current situation looking
for WiFi spot, getting login, always unpredictable bit rate is quite silly.
I think when it will be established hopefully the market forces will make it
reasonably "state of the art" otherwise will be a little use of it.

BTW, just wanted to add that this business about "super WiFi" is "super
silly."
What does "super" mean?
If you want to use low frequencies to go a very long distance, great, but
then you have to accept the *scaling* aspects of the problem. Just like
two-way DBS is not practical in dense market areas, the same applies to
WiFi.
Two-way comms require a high degree of frequency reuse, to scale effectively
in dense areas. The low frequencies and long range of TV spectrum can be
used for long range quite well, but by definition that won't allow for
frequency reuse.
What's so "super" about allowing, say, 100 MHz of WiFi spectrum for a
metropolitan area, when I already today have 40 MHz just in my own home?
