We have an applicaiton that is sensitive to network speeds. Is there a way to guarantee a minimum wireless network speed such as 100 MBs utilizing a 5508 controller and 2602e APs?
Not easy. Wireless is a shared medium. This means if one client talks, everyone else has to stop and wait for their turn.
It's like doing video. Video is time-sensitive. If you put a single AP in a room (granted you've got full 1Gbps ethernet access all the way), and you get 25 people continuously streaming videos, then you'll see some impact. Bring the number down to say, 8 to 10 and you'll see improvements.
What kind of application are we talking about here?
