I've posted how to do range calculations about 30 times in this
newsgroup. The circumstances vary depending on the situation but
there are some basics that need to be known.
1. What kind of antenna do you have?
2. What kind and length of coax the radio?
3. What tx power and rx sensitivity does the radio run and at what
speed? If you don't have these, the model number of the radiow will
suffice.
4. The same information a 1->3 except for your WISP provider.

An excellent idea. 2.4GHz does not go through anything with water
inside. Trees (foliage attenuation) are like a wall depending on
density.

For good reason. Can you guarantee line of sight and Fresnel Zone
clearances? If not, it won't work very well. But even if you had
these, there's still the possibility of interference, reflections,
multipath, and installation defects. That's too much to go wrong to
offer you an SLA (service level agreement) which seems to be what
you're expecting.

I once was I nice guy. Then, I helped start WISP. No more nice guy.
Same with becoming a landlord. It just goes with the territory. Don't
let it bother you.

Here's the way wi-fi channel loading works.
100 customers doing general web surfing and email.
10 business customers doing whatever business customers do.
1 file sharing user.
I originally wrote that as a joke, but it seems to be quite real. My
guess(tm) is that your un-named WISP doesn't have any bandwidth
management or bandwidth limiting in place. That means that one user
can hog the entire bandwidth.
Maybe it would be easier to chain saw the trees.
