Mimosa WiFi 6/AX: 6ghz channel support

Due to AU compliance regulations as well as current software limitations, the Mimosa WiFi 6/AX products do not support the expanded 6GHz channels - 5925-6425 at this time.

The relevant Compliance document for Australia is the Radiocommunications (Low Interference Potential Devices) Class Licence 2015 item 63AB:

In short, the use of the the new channels is permitted, but at max EIRP outdoor limit of 25 mW of output power, or roughly 14dBm.

The Mimosa A6 radio has an integrated 16dBi antenna, therefore the lowest TX power we are able to operate this device is 5 dBm, which subsequently exceeds the total output allowed. The current A6 software revision, does not address the ACMA limitations, but future releases may add additional support.
