PTP 850E - How Does the Licensing Work?

Since the PTP 805E are using licensed bands within the FCC region, you have to purchase licensing keys, along with selecting the frequencies within the design. How does that process work in terms of purchasing process? Does a reseller that is purchasing/designing the solution have to register/apply for those frequencies from the FCC first? Or is there different regional/local authorities that handle this licensing which the reseller must check with first before purchasing to make sure their is spectrum available?
