@answermaxx CPE can build point-to-point connection but it only has direction antenna. My suggestion is EAP225-Outdoor as the main Acess Point, it can send signal to all directions. And on the roof of each cabins you can add another EAP225-Outdoor to build the mesh network. You will also need a hardwrae controller to keep the mesh netwrok running.

If you still want to use CPE, here is another article: https://www.tp-link.com/us/support/faq/1225/

It mentioned WBS serious but I'm not sure if it is still available in the market. 

@Somnus Thank you very much for your advice.  I am going with two EAP225 and the controller.  I really appreciate your help and expertise.
