Wireless Controllers
Contact UsContact UsContact Us

Award-winning wireless appliances provide an exceptional user experience, regardless of location.

Our Wireless Controllers are simple to deploy and manage, yet provide advanced functionality to allow organizations to define how wireless voice/video/data traffic is processed without architectural constraints and in accordance with the business needs.

The Wireless Appliance portfolio includes:
  • The C35 supporting up to 250 APs
  • The V2110 supporting up to 1,050 APs
  • The C5210 supporting up to 2,000 APs
  • The C5215 supporting up to 2,000 APs

Virtual and physical appliances have resiliency built in from the start; no additional software to add or purchase. Running as active-active pairs, if an appliance happens to fail the other appliance is able to take over the full load while maintaining access point connectivity. Failover occurs within milliseconds; access points continue running without interruption to existing or new client connections.

  • Scalable to 2,000 Access Points per wireless appliance with unified management of 802.11ac and 802.11n Access Points
  • Seamless roaming with centralized and distributed forwarding
  • Integrated wireless IPS to proactively protect against security threats
  • High-availability architecture for real-time voice/video/data applications, included at no additional cost

Virtual Network Service (VNS) – an adaptive WLAN architecture.

Wireless Virtual Network Services control traffic flow by allowing traffic to be backhauled to a wireless appliance or switched locally at the AP on a per SSID basis. With local switching, the AP is still managed centrally by the wireless appliance, but data is not backhauled to the wireless appliance. This improves responsiveness and ensures that traffic does not unnecessarily traverse costly WANs or contribute to bottlenecks at aggregating switches. A VNS also provides role-based policies providing security, NAC, mobility, and QoS priority that can be implemented on a per user and per application basis.

Integrated management and control across wireless and wired networks.

  • Web-based centralized management via Wireless Assistant
  • Multi-appliance management
  • Integrated security

High performance and high availability.

  • High scalability
  • Fast and secure roaming for seamless voice and data mobility
  • High availability and self-healing

Wireless APs also feature dynamic radio management, which enables the network to automatically adapt to changes in the RF environment or failure of any individual APs, ensuring availability and performance to users. Each wireless AP continuously monitors channel use, signal-to-noise ratio (SNR) for interference, and the receive power of neighboring APs ( or third party) to adjust their channel and transmit power.

Business alignment
  • Support for demanding voice/video/data applications to enhance mobile worker productivity and convenience
  • Role-based grouping of users, devices, and applications to deliver priority, QoS, and security in accordance with business needs
  • Integrated management, security, and QoS features reduce operating cost and ensure a consistent user experience regardless of location
  • Key element of mobility solutions that enable VoWLAN and dual-mode devices
Operational efficiency
  • Centralized visibility and control to simplify management, accelerate problem resolution, optimize network utilization, and automate response to wireless threats
  • Integrated wired and wireless management and role-based access control greatly reduce administration time and effort
  • Adaptive architecture reduces complexity and optimizes information flow for each application
  • Authentication and authorization functions include role-based access control using 802.1X, MAC authentication, and captive portal
  • Standards-based encryption (WEP,TKIP, WPA, WPA2, WPA-PSK, WPA2-PSK, and AES)
  • External captive portal allows full customization for guest access
  • Integrated wired and wireless intrusion prevention
  • Denial of Service (DoS) protection for management, control, and data traffic
Support and service
  • Industry-leading customer satisfaction and first-call resolution rates
  • Personalized services, including site surveys, network design, installation, and training
