If you allow EAP245s to be used as Root Nodes, then you can have EAP225s outside the building connected via wireless mesh.

Outside Canada, Russia, Japan, EU, Switzerland: yes.

In Canada, Russia, Japan, EU, Switzerland: no.

Reason is that U-NII-1 frequency band is allowed only indoor in listed countries, but not outdoor. You need to limit the channels in EAP225-Outdoor APs to those allowed for outdoor use (firmware/Omada Controller has a setting to avoid use of indoor channels on EAP225-Outdoor). So, EAP245 choosing indoor channels for the mesh can't be a root node for EAP225-Outdoor in countries listed above.

Thank you for your answer. Can you tell me where I can find this channelsetting in the OC200?

In OC200 firmware 1.1.1 it's in menu Wireless Settings → Advanced Wireless Settings → tab 5 GHz → Channel Limit

In previous (software) controller versions it is in EAP Configuration window → Radio → tab 5 GHz → Channel Limit   (only visible in the config window of an EAP225-Outdoor)

BTW: you could use an EAP225-Outdoor also indoors and enable channel limit, although I would recommend to mesh outdoor nodes with outdoor root nodes only. In my experience, meshing an outdoor EAP with an indoor EAP will probably attenuate the WLAN signal too much (depends on material of the walls and other obstacles in between the two EAPs).

I enabled the channels limit function as mentioned in your post. Still I can 't find the eap245 in the pending list. This eap245 isn't connected by utp (only for power).

Yes, as forrest wrote above EAP245v3 does not (yet) support meshing. I just wanted to point out in response to RMM949 that it's problematic to mesh outdoor EAPs with indoor EAPs (e.g. EAP225-Indoor) in countries where channel limits apply. I think TP-Link will soon publish a firmware for EAP245v3 which supports meshing - they usually do very detailed tests before releasing a new firmware and this takes some time.
