in that case you are right in deploying a WLC at each site.

One thing to keep in mind that I like to do in my remote locations is, assuming you are using PoE to power the APs, make sure you note the switchport that you have them plugged into in case they ever get hung and WCS/WLC cannot talk to them. A simple shut/no shut on the port will reboot it and that nearly always corrects my issue.

When I 1st deployed the wireless network I didn't document very well and when one got hung up and I couldn't see it in the CDP neighbor table I had to call users and ask them to do me favors. Much easier to do it myself.

had one more question. I am building this to scale with the default network being 802.11n. Using the same access points, can i have multiple wireless vlans i.e a vlan for guest, vlan for certain applications.

Yes. You can have multiple WLANs being broadcast out of each AP. We have four being broadcast out of each of our APs.

so the final take is one acs and multi wcs for my install
