Access Point Naming

[evanp456]

I am interested to purchase a Catalyst Access Point like the Catalyst 9115. However I find many variations such as 
C9115AXE-E
C9115AXE-H
C9115AXE-EWC-E
C9115AXI-E
C9115AXI-EWC-E
What the letters AXE-E, AXE-H, EWC-E and so on mean?

I can simply say -X means regulatory domain ) 

AXE and AXI - External and Internal antenna

you can find more details in the specification section :
