• Most common SSID design for enterprise organizations includes 2-3 different SSIDs – Employee users – strong authentication and encryption suite – Application – devices not capable of strong authentication and
encryption levels – Guest access – will not run any encryption; requires
authentication

Deployment Considerations
• How big / how many subnets do you need to support your devices (not just users)?
• How will the APs discover the master controller?
• How will the installer let you know where the AP was mounted?
• How will RAPs be configured, IT or end user?
