ProSAFE Wireless Controller
System Planning Concepts
This section includes the following subsections:
• Preinstallation Planning
• Before You Configure a Wireless Controller
Preinstallation Planning
Before you install any wireless controllers, determine the following:
• Number of access points required to provide seamless coverage
• Number of licenses required to cover all access points that must be managed
• Number of wireless controllers required
• 802.11 frequency band and the channels that are optimal for WiFi usage
We recommend that you perform a site survey:
• To determine the current RF behavior and detect both 802.11 and non-802.11 noise, run
a spectrum analysis of the channels of the site.
• To determine the maximum throughput that is achievable on the client, run an access
point-to-client connectivity test.
• Identify potential RF obstructions and interference sources.
• Determine areas where denser coverage might be required because of heavier usage.
Before You Configure a Wireless Controller
These sections assume that you deployed at least one wireless controller in your network
and are ready to configure the wireless controller. For information about how to deploy the
wireless controller in your network, see your model’s installation guide, which you can
download by visiting downloads.netgear.com.
For many configurations, you can use the default WiFi settings. The IP address, VLAN,
DHCP server, client authentication, and data encryption settings are specific to your
environment. Following are short sections that describe these settings (except for IP address
settings, which are self-explanatory). For information about how to configure these settings,
see the relevant sections.
Management VLAN
The management VLAN is the dedicated VLAN for access to the wireless controller. All traffic
that is directed to the wireless controller, including HTTP, HTTPS, SNMP, and SSH traffic, is
carried over the management VLAN.
If the management VLAN is also configured as a tagged VLAN (the most common
configuration), the packets to and from the wireless controller carry the 802.1Q VLAN header
with the assigned VLAN number. If the management VLAN is marked as untagged, the
