 20-AP Wireless Controller 
WC7520
RF Management and 
Hole Detection
With integrated RF planning tools, an administrator can input floor plans, building dimensions, 
and desired coverage. The planning tools compute the predicted RF characteristics of the 
building, and display predicted coverage. Automatic control of AP transmit power and channel 
allocation ensures coverage by minimizing interferences. Automatic WLAN healing after loss of 
AP or due to RF interferences adapts the power and channel of the other APs around the area. 
Scheduled automatic channel allocation authorizes enterprise-class reliable Wireless experience.
Load Balancing and 
Rate Limiting
Automatic load balancing of clients across APs is provided based on number of clients per AP, 
and signal strength threshold/data rate threshold of clients on the BSS. Rate limiting is provided 
by SSID. Load balancing and rate limiting ensure fair bandwidth allocation among all clients for 
robust wireless connectivity. 
Fast Roaming and 
Voice Over Wi-Fi
The NETGEAR ProSafe 20-AP Wireless Controller supports rapid mobility across VLANs and 
subnets including 802.11i pre-authentication and fast roaming support (FRS). Seamless L2 and 
L3 roaming provides support for latency-sensitive applications such as video, audio and voice 
over wireless. Wi-Fi Multimedia (WMM) advanced prioritization extends Wi-Fi’s high-quality 
end-user experience to voice applications (VoWi-Fi). 
Heat Maps and Triangulation
AP heat maps by wireless band, wireless channel and signal strength allows real-time view 
of the wireless network status. Administrators can easily locate known APs, rogue APs, and 
associated clients on the heat map directly from the monitoring page.
Monitoring and Reporting
The WC7520 has a heartbeat mechanism between the controller and the AP. It is monitored 
based on several factors, such as RF interference, clients, error levels, etc.
Each AP is constantly monitored (number of clients, traffic load, RF interference, packet error 
levels and retransmission statistics). Statistics provide reliable metrics per AP, per client, per floor 
and for the entire wireless network.
Performance
The best of centralized and distributed architectures are implemented by the NETGEAR ProSafe 
20-AP Wireless Controller for outstanding Wireless-N performance. Local traffic is automatically 
switched at the access points level for fastest processing, when roamed L3 traffic is processed at 
the controller level with advanced data control. Real-time applications such as VoWi-Fi require 
perfect inter subnet/inter VLAN mobility: WC7520 encryption tunneling delivers enterprise-class 
fast roaming without any impact on Layer 2/Layer 3 performance.
Supported Access Points
Supporting standard NETGEAR access points, the WC7520 Controller enables customers to 
select the right access points for their needs, even mixing models to provide the right coverage. 
The standard access points are converted to dependent access points. Supported models include 
professional-class ProSafe access points WNAP210, WNAP320 (single band) and WNDAP350, 
WNDAP360 (dual band), all with Power over Ethernet capabilities and lifetime warranties.
Example of Wireless-N configuration with 120 access points (AP) and one redundant controller.
