Today's corporations and WLAN service providers recognize the importance to provide secure mobile network services to their staffs or customers to build differentiation, increase productivity and foster competitive advantage. The 4ipnet Secure WLAN Controller series (WHG-series) is built to scale network management capabilities for your WLAN deployments of all sizes - in enterprises, institutes, or hotspots - to provide centralized WLAN management and comprehensive secure network protection.

The WHG-series integrates "secure access control", "seamless mobility", "visitor account provisioning", "flexible accounting and billing", and "centralized WLAN management" into one box to provide a unified, high performance solution for converged data and voice applications. Following 802.11 b/g standards, the WHG-series Controllers are capable of managing from 12 to 150 access points centrally to cover different scales of WLAN deployments.

Features and Benefits:

Excellent Compatibility with Existing Network
No restructuring of existing network is required. 4ipnet's WLAN Solution is optimized to support 802.11 b/g standards and can be easily deployed as an overlay, leveraging existing infrastructure to preserve time and money on IT investments.

Secure Wired/Wireless Connections
The Controllers provide excellent, well thought-out wireless LAN protection that integrates with your existing security devices to satisfy all your network needs. Support standard-based data encryption such as WEP, WPA, WPA2, 802.1X, and IPSec VPN. No additional installation of client software or difficult configuration is required to setup IPSec VPN tunnels. Other features include built-in DoS protection and flexible firewall rules to prevent malicious hackers from collapsing the network.

Multiple Authentication Methods
The Controllers support multiple authentication methods. Built-in local and on-demand database can act as a standalone authentication server. In addition, they support external authentication servers such as RADIUS, POP3, LDAP, Windows Active Directory, and SIP registrar. Each Controller not only works as a standalone gateway for a single WLAN, but also supports cross-location roaming for larger deployments, such as in chain stores, with a backend authentication server like RADIUS.

Centralized Access Point Management
Offer centralized remote control and monitoring of managed APs via web-based administration interface, including AP's system settings, online status, enabling/disabling, reset, and firmware upgrade. Periodically monitors APs and notifies the administrator when APs disconnect.

Seamless Secure Mobility
Account roaming and AP roaming provides unlimited freedom of connectivity for mobile users and devices to securely access Internet or enterprise network.

Resilient Identity-based Access Control and User Management
Role-based access control and policy enforcement offer management of privileges for different user groups. Service Zone function partitions a physical network into multiple virtual networks, each with its own definable access control and group policy profiles. Allow hotspot owners to provide customized services for different levels of users. Individual user bandwidth, session, and login schedule management enables flexible traffic control and fair network resource utilization.

Instant & Managed Guest Access
For corporations, the Controllers can instantly generate secure, manageable guest accounts for visitors. The Controllers also support IP Plug and Play (IP PnP) function so visitors can connect to the corporate WLAN without changing their TCP/IP settings when they use Static IP.

Account Provisioning and Flexible Billing
To fulfill the needs of hotspot business operation, the Controllers are equipped with instant account generation and flexible billing capabilities. The instant account generation feature allows hotspot operators to generate one-time accounts for coming customers. The built-in billing profiles enable operators to charge different rates based on connection time and data volume. Customers can obtain and pay for Internet service online using their credit cards through Authorize.net or PayPal.

Support for VoIP
By acting as a SIP Proxy, the WHG-series Controllers can support VoIP calls, without the need to reconfigure VoIP devices such as SIP-based WiFi handsets. To ensure quality of service (QoS), the Controllers can further assign high-level of bandwidth utilization for voice and video packets. For call control, they can be set to only redirect SIP call requests to up to 4 trusted SIP Registrars.
