I work in a theater that has a really crowded wifi spectrum and the
building is essentially a big metal box.
...
We have noticeable dropout issues all the time.

PS: If anyone has a good solution to this sort of crowding, I'd love to
hear it.
The point of unlicensed ISM band operation is you get a lot of freedom to
play with different protocols, etc. because the power is low enough it
only affects your own premises.
If you can't control the broadcasting devices on your premises, then you
need to change to licensed spectrum devices (like UHF band microphones).
Tried directional wifi antennas, and/or powerline networking, for
nonportable needs? Otherwise, indeed, licensed spectrum sounds to
me like the option. I would definitely take the crew comm off
2.4GHz off one way or another, there are a lot more options for comm
out there, and no matter what doing this will help things.
