WiMax frequency range confusion...any help?

R. Ticle
Okay - after spending at least half an hour with "technical support"
from Sympatico WiMax unplugged, trying to figure out the range at
which this abomination operates (so as to know if I'm gonna be able to
measure for better areas with what I've got), I get told by the rep
that it operates at 30 to 3000 khz, which translates into 0.03 to 3 MHz.

Huh? Say what? That's like ULF, or VLF, isn't it? Like Ultra, or Very
Low Frequency? That's not even measurable by conventional gear. In
fact, I don't believe that even falls into the range of "microwave" at
all!

Is it possible that they operate at that, thus rendering any meter
unusable to find, or was I given some obscure and incorrect piece of
information by a tech support guy who'd never been asked that question
before and had to consult a manual (as may have been the case from the
long periods I was on hold on the phone for)?

My assumption was that WiMax or any such wireless internet service
operates at higher frequencies, 2.4 GHz or higher.

What's going on? Tell me that it was just technical incompetence, and
that, not that I want to have to, but if I needed to, I could check
areas for non-cell phone (instead, wireless internet, be it called
WiMax or otherwise) signals, with currently available equipment.

Any thanks hugely appreciated!

Cheers,

R.

Wimax may be at several different frequencies, and the signal may be pulsed
or even not-pulsed, according to waht the provider thinks best.

But normally, we measure it between 3.410 and 3.594 MHz, or 3,4 -3,5 GHz.
The used bandwidth may be 3,5 or 7 MHz.
