Hello WiFi admins

In FAP-231K datasheet, the AP supports 802.3bt (PoE++), 802.3at (PoE+) and 802.3af (standard PoE).

What is the exact impact (on all aspects) if using .3at or .3af instead of .3bt?

On 802.3at, the AP will be fully functional. In 802.3af there are limitations:
1. 802.3at: Tx Power - Full, 2x2 MIMO
2. 802.3af : Tx Power- Full, 1x1 MIMO

Thanks Emirjon

So as long as it works we can use dot3af as a temporary workaround.
