Thank you both for the very helpful details!
For question 1, we already have devices grouped according to specific SSIDs. The problem I am experiencing is how some of the mobile industrial devices will become "sticky" to the APs on the adjacent floor it may have been used on previously. How does the Cisco wireless system mitigate this issue?
There may not be an "easy button" the information may be cached on individual devices. You may have to clear caches of the individual devices by getting endpoint devices to forget those mac addresses of the APs they connect to.
For question 2, I have heard that there is almost like an approximate 3/1 ratio. That is, 3 data devices to 1 VoiP or Video device. Any thoughts on this?
Every AP coverage and capacity will be different. You'll have to look up the model and instead of making a generalized ratio, unless you know. The safe bet would be how I described in the earlier approach.
A follow up question I have is: What is Cisco talking about how the "Switching APs in a multi-subnet environment changes the roaming activity from a seamless Layer 2 roam to a Layer 3 roam," ? If you can please, I would like a deeper explanation of this.
A "multi-subnet" environment means that you have different subnets. As you move your wireless devices from one AP to another AP, all supporting multiple subnets. Applications that require persistence do not need Layer 2 when roaming across multiple access points but Layer 3. So as you move from an access point on floor to another floor, this allow for applications to maintain their connections, this is part of Mobile IP networks.
Cordially,
