I'm working on a big project. We want to create a wireless network throughout the building with 15 floors. My idea is that we should set up one unified wireless access point at least in each floor...in case of signal attenuate, we use Access point extender/repeater. I selected DWL-6600AP from among D-Link industrial access points. I want to implement a single wireless LAN throughout the building.

Is it possible to combines multiple DWL-6600 access points to achieving just a single WLAN? Can a wireless switch controller do this task? Can these Access Points interfere with each other? What is the solution? I read D-Link website's learning materials, but I am still confused.

My other question is around the connecting these APs to Wireless Switch Controller - Is it possible to use power line for connecting DWL-6600 to Wireless Switch Controller device?

My main goal is that clients with portable devices such as laptops should be easily connected to the network to share & have communication without any more manual configuration as they are already connected to a single network.
