Setting up a group of R510s is a controller needed?

[bdillard]

Hello,

I'm new to ruckus but have heard great things.    If I want to set up a warehouse with about 18 is a controller needed?   Should I get a different unit?   Some APs I've worked with need a controller, some need a special version of the AP with a controller built in - I'm not sure about Ruckus.

Thanks
