I am in the process of purchasing a 6500 and I need to understand if I need to purchase a wism and if it is relevant to my wireless network. I have 3 controllers at 3 diff sites. Each manage approx 20 access points. I plan on rolling out more controllers to my other sites and somewhere down the line expand the number of access points per site.
My question is, if I place a wism in my core switch, I will not need to purchase addiitonal controllers as I deploy wireless solution to futrue sites? From my understanding I thought best practice was to place a contoller at each site in on your wan.
