Indoor CW916x APs do not have integrated GPS. However, a GPS is not required for AP Auto Locate! AP Auto Locate works by using RF to accurately measure distances between your APs, and then using that information to determine each AP's relative position to one another. We then ask you to manually place a few "anchor" APs and the rest will automatically position themselves on maps.
It works on the following AP models in Meraki mode, and there is no dependency on Cisco Spaces:
CW9166, CW9164, CW9162, MR57, MR56, MR36, MR36H, MR78.
If you have tried it, I'd like to hear about your experience with the feature!
