Firmware 2.5.3 Freq Update

We just upgraded one of our A5c’s to 2.5.3 and noticed this feature:
“A5/A5c, C5/C5c/C5x supports operation in the Experimental UNII-4 frequency band (5.850 - 5.895 GHz) in the United States.”
Was not available… Is this still not authorized?

No it is not authorized yet. The FCC is still considering OOBE limits for that band and we do not have complete technical rules to certify against. Until then, the only option is experimental STA application filings with the FCC which we’ll support if paperwork is provided to us as evidence that you’ve been granted a temporary license.
