which is not dependent from manufacturer, but physics, and more important 
in lower frequency. Calculations are easily found in the net.

and there are few meters to be counted too because earth is not flat.

it works if done precisely enough :)

  There is a ton of functionality and I actually use two of them for my core routers
at my current job.  I think for this project they are overkill and there is quite a
bit of a learning curve to get them up and running.  If you don't plan on deploying
anything else, I think that you will find that the tranzeo's are a 
simpler solution.

generally - simple radio bridges. you put one to DSL router, and other to 
computer/switch. that's all.
