"An automated frequency
coordination system will prevent standard power access points from operating where they
could cause interference to incumbent services. " and it looks like it's also allowing higher power, 41.3 dBm ?
Looks and smells like CBRS/SAS :(
You won't be seeing that on ePMP via a firmware upgrade. Also, I don't believe any of the antennas on the integrated radios will work at the higher frequencies. The ePMP 3000 sector is listed as 4.9 GHz to 5.97 GHz , no firmware upgrade will change that.
You can get a Special Temporary Authority from the FCC right now to use 5850-5895 and a firmware upgrade from Cambium will enable it on the radios once you have the STA.
