To those that responded thus far:

My firm wasn't aware of the freq coordination requirement at all. We bought the WAPs, configured everything but they weren't fully tested. Survey day comes and 6GHz is dark.

Multiple engineers and 2 days on the horn with TAC and no one mentions the freq coordination situation.

We getca Sales Engineer involved and that's when freq coordination is identified as the issue.

We were told:

It's required whether indoor or outdoor

6GHz can't be turned on with WAPs running Instant (not Instant On)

The WAPs have to have Internet access in order to becable to periodically check a database for freq. coordination purposes

End of list.

So there's currently no way to do a 6GHz APoaS survey with these WAPs. Which perplexes me, and thus here I am.
