Thanks Richard for quick reply and apologies for my late reply and additional questions
We are initially deploying 9 WAPs in one office. We have 3 offices and a Datacenter. connected over a MPLS network.
1- Is it recommended to place the controller in the Datacenter and just WAPs in the offices. So the connectivity between WAPs and controller is routed over MPLS
2- What are integrated controllers?
THis additional information might change recommendation to different WAP and controllers models.
