We're a school district with approximately 25 sites in a metro ethernet configuration, and we're starting to roll out our wireless infrastructure (WCS 5.1/WLC4400s/1252s) on a pilot basis.
Our goal is to provide 3 SSIDs, organization-wide.
I'm told that many large orgs use a /21 and even a /20 for enterprise wireless VLANs.
Are there guidelines or best practices for subnet sizing of wireless VLANs?
We'd like to have the same SSIDs, organization-wide and keep configurations as simple as possible. It sounds like using larger VLANs might be the way to go.
Thanks in advance
