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.
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.
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).
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.
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.
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.
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.
