RF spectrum is a limited resource, and the FCC just made more of it available to connect the unconnected. But how do network operators make the best use of the new frequencies released by the FCC?
CBRS, or the Citizens Broadband Radio Service, is 159 MHz of spectrum in the 3.5 GHz frequency band. Ranging from 3550-3700 MHz, 80 MHz of the band is reserved for General Authorized Access (GAA). The base band technology that network operators choose to use when deploying CBRS is an important decision. The ROI for each technology is based on complex assumptions. However, when the network operator breaks it down to each of the issues and weighs the factors for each, the ROI calculation will make the right choice become obvious.

You mean the PMP450m 3GHz? It's available world-wide. CBRS however, is only for USA/FCC land.

What does a wisp need to run in this CBRS band ... besides the equipment of course.
Like do you need to apply for the license and/or Cambium help with that ?!

If you're planning to use Cambium equipment in CBRS, then the requirements are fairly simple.
You need to have at least one CPI (Certified Professional Installer) working for your organization. There are no "licenses", no applications, and no need to directly contact the FCC anymore...
Eric posted a link to the announcement, which certainly has additional information about this, but keep asking questions so we can clarify.
