The first proposed propagation they gave me of a 5Ghz tower looked like a full circle with 99% coverage. This is with rolling hills and a handful of trees. Even well above EIRP that wouldn't be realistic. I asked them to tone it down (I forget the exact terms) and they came back with a much more realistic map. All other towers seemed more accurate, but are much smaller AGL.
Also, it is fixed wireless broadband =) Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Thu, Aug 4, 2011 at 4:38 PM, Brian Webster <[email protected]>wrote: > Let me state that Connected Nation does a great job of working to map fixed > wireless operators in the states they have contracts from what I have seen. > The work I am doing in Illinois is a handoff of the work Connected Nation > did prior to their contract expiring.
