HD2, wifi 5GHz

Does the HD2 hardware revision 4 support 5GHz wifi?

Specs are right on peplink.com: https://download.peplink.com/resources/pepwave_max_hd2_datasheet.pdf

That datasheet is only valid for revision 6 and probably 5. I am asking about revision 4.

The internal AP will only use 2.4ghz. The software seems to be able to control an external AP though that may have 5ghz.

Wifi-Wan is additionally limited to 2.4ghz also. It will not pick a 5ghz signal at all.
