I'll chime in with a few comments: I admit to having been frustrated by the requirements in the 3.65 GHz ruling by the ambiguity of the cooperation requirements and for sure there are no first in rights. However, what I am seeing thus far in practice is that first movers do enjoy a meaningful advantage in their markets. Since WiMAX does represent a more significant CAPEX investment on infrastructure, operators are reluctant to deploy aggressively in a market where several operators are already live. Second, since the rule does not define neither the nature nor extent of the cooperation, the first in operators seem to have a leg up with the next in folks needing to work around them to some extent. At a minimum, cooperation as it relates to 3.65 GHz is a boon for the lawyer class and since most WISPs are loathe to deploy an attorney to battle the first in's attorney, many opt to find greener pastures. Also, according to me Redline friends, we are learning that the FCC has rejected some registrations of multiple operators on the same tower site. So on balance, the interference risks in 3.65 GHz are minimal as compared to 5.x GHz and certainly the other ISM bands.
I do wish that the FCC would use some of the 3.65 HGz license fees to create an enforcement pool, as well as defining a more specific set of rules and procedures for the human side of 3.65 GHz cooperation.
