Multi Locale Access Points into a single controller?

I will try to make this short. We use Ruckus. We are deploying Access points at remote locations in Europe and the Middle East (Kuwait), and management is wondering if we can manage them all with a single controller? I have no experience in this regard, but I know wireless certifications for the EU, and North America are different. I have reached out to Ruckus, and am awaiting a call back...but I am always suspicious of front line sales people.

Does anyone have any experience with such a scenario under any wireless vendor? I am wondering if we should just have two separate controllers to properly manage the different bands and frequencies. Thanks in advance!
