Pat...what exactly are they saying to you. It is not easy. You may have
to get a 3rd party engineering firm to tdo the analysis. I dealt with
COmsearch for awhile before I switched jobs. Comsearch did one or two
analysis' for a Wisp and I think that was it and they dropped it off
their offerings to be rethought out.

The FCC describes an alternative for determining a safe distance for
locating a station with in an FSS protection zone in Appendix D of the
Report and Order authorizing the 3.65 - 3.70 GHz band. You can read the full
document here:
http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-05-56A1.pdf
This is the intro to the appendix.
*********
APPENDIX D: A Methodology For Locating Fixed Stations Within The FSS Earth
Station
Protection Zone
The rules adopted herein require that fixed stations in the 3650-3700 MHz
band be located at least
150 km from any grandfathered FSS earth station unless all affected
licensees agree on closer spacing.
Below, we present as an example, one methodology that can be used to
determine a safe distance within
the FSS earth station protection zone where a fixed station can be located
without increasing the potential
of that station to cause harmful interference to the earth station. We
reiterate that this is being presented
only as an example of one methodology. We recognize that there are many
methods for providing the
required protection, such as locating the fixed station behind an
obstruction, and that licensees are free to
propose any method they deem appropriate.

I would assume that you could use this method to calculate the safe distance
for operating at 3.65GHz and present it to the FCC and the FSS earth station
operator.
I will need to do this for my WiMAX deployment which will have two mountain
ranges between the WiMAX network and the earth station.

Anybody else having any luck with these people. They're trying to tell
me I might have to clear all my customer sites for a proposed WiMax
deployment on a case by case basis. I'm at the edge of the 150km
exclusion zone and have a mountain range in between us. This is
getting
really annoying.
Thanks,
Pat
