After understanding your security requirements, you can then define the zones (and interfaces) and VAPs that provide the most effective wireless services to these users. The following are examples of ways you can define certain types of users.
WEP & PSK – Moderate trust wireless zone. Comprises two virtual APs and subinterfaces, one for legacy WEP devices (for example, wireless printers, older hand-held devices) and one for visiting clients who use WPA-PSK security.
Guest Services – Using the internal Guest Services user database.
LHM – Lightweight Hotspot Messaging enabled zone, configured to use external LHM authentication-back-end server.
