RouterOS Wireless Networking

Hi all!
Our customer has SXT Sixpack bundle. He wants to realize such scheme. Central site with SXTG-5HPnD-SAr2 connected to LAN by trunk, remote sites with SXT-5HPnDr2 connected to LAN by access ports:

Tell, pls, this scheme can be made using SXT devices?
And other problem which I met is related with licenses. When I try to configure a Virtual AP, devices say that they have the wrong License.

Yes, you can set that. For Ap you need level 4 licence at least.
