Using 3.65GHz For Wireless Surveillance?

While 2.4Ghz and 5.8Ghz are the most well known bands for wireless systems used in surveillance, another band exists (at least in the US) that some say can and should be used for surveillance - the 3.65Ghz band. I am curious if anyone is making use out of it?

Here's an excellent survey article on 3.65Ghz and a key extract:

"The 3.65 GHz band is licensed on non-exclusive basis; hence, it is referred to often as semi or lightly licensed. Operators obtain a license from the FCC and register their systems parameters and coordinates in a database (a license can be obtained for nominal fee of $260 for 10 years). Operators have the responsibility to minimize the potential of interference to deployed systems. The process to resolve interference is left to the operators themselves. The FCC requires that all systems implement a contention based protocol (CBP) which would stop transmission if the system detects transmissions from other systems."

Biggest benefit is less risk of contention. However, there are evidently some geographical restrictions typically in urban US areas where Fixed Satellite Services (FSS) space-to-earth operations have been grandfathered in.

Anyway, I am hoping others can share experiences of why they did or did not use this band for surveillance.
