This is my first time into the wireless side. I need to scale a solution for a large campus. I have an idea of the number of APs required to cover the area, but I don't know how many end users can connect to a given AP, and presume there is some limit? I'm particularly interested in how to do this in auditoriums where it is a large open space, but with many delegates. So is there a general rule of thumb on "not more than x users per AP"? The plan is to have all APs linked together using a WLAN controller.
Other question: is there any functional difference between having dedicated 4402 / 4404 WLAN controllers and using a WISM service module in a Catalyst 6500 series switch?
Thanks in advance.
