3650 mhz

The 3650 mhz frequency is a partially licensed band. Maybe better to say controlled band, where there is some control of who uses it. Not like a license. . . which means not free range, free anywhere like the ISM bands. Get the licensing out of the way, and the spectrum is useful for many situations, at low cost to license. For long range p2p connections, it maybe ideal. Check out Siemens products:
