ProSafe® 20-AP Wireless Controller WC7520 RF Management and Hole Detection Load Balancing and Rate Limiting Fast Roaming and Voice Over Wi-Fi Heat Maps and Triangulation Monitoring and Reporting Performance Supported Access Points 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.
