Client devices supported for each AP

I’m Faisal from Libya, I work in WISP company
The company I work for works with UBNT devices and they are planning to Migrate to Mimosa
I have a question
What models of client devices are supported by the following Access Point :

The A5c supports all C5# (C5, C5c, C5x) devices as well as the planned C6 devices (depending on the wireless settings of both devices.

The A6x does not exist as far as I am aware.

The A6 will support C6 hardware, though may be able to support C5# devices depending on the wireless settings used.
