Overview of Wireless Networks
Once you have completed the ZoneDirector Setup Wizard, you have a fully functional
wireless network, based on two secure WLANs (if you enabled the optional guest
WLAN) with access for authorized users and guests. The default WLAN provides
Zero-IT connectivity to allow users to automatically provision their client devices with
WLAN settings the first time they connect. The guest WLAN provides visitors to your
organization with a connection to the Internet, but not to your internal corporate
network.
There are several scenarios in which you will want to create additional WLANs, in
addition to the default internal and guest WLANs:
• To limit certain WLANs to groups of qualified users, to enhance security and
efficiency (for example, an “Engineering” WLAN with a closed roster of users).
• To configure a specific WLAN with different security settings. For example, you
may need a WLAN that utilizes WEP encryption for wireless devices that only
support WEP-key encryption.
• To create special WLANs with different settings for specific purposes. For
example, a VoIP WLAN for voice traffic with Background Scanning and load
balancing disabled, or a student WLAN that is only available during school hours.
In the first scenario, specific WLANs (esp. regarding authentication and encryption
algorithm) can be set up that support specific groups of users. This requires a two-
step process: (1) create the custom WLAN and link it to qualified user accounts by
“roles,” and (2) assist all qualified users to prepare their client devices for custom
WLAN connection.
As a result, you will have the default WLAN for authorized internal users, a guest
WLAN for visitors and any needed WLANs that fulfill different wireless security or
user segmentation requirements.
The maximum number of WLANs configurable per ZoneDirector controller are as
follows:
