Simple and Secure Wireless Deployment and Management for Small and Medium-Sized Businesses and Enterprise Branch Offices.
The Cisco® Wireless LAN Controller Module allows small and medium-sized businesses (SMBs) and enterprise branch offices to cost-effectively deploy and manage secure WLANs. The module provides unparalleled security, mobility, and ease of use for business-critical WLANs, delivering the most secure enterprise-class wireless system available. As a Cisco Integrated Services Router module, it delivers centralized security policies, wireless intrusion prevention system (IPS) capabilities, award-winning RF management, quality of service (QoS), and Layer 3 fast secure roaming for WLANs. The Cisco Wireless LAN Controller Module manages up to six Cisco Aironet® lightweight access points and is supported on Cisco 2800/3800 Series integrated services routers and Cisco 3700 Series routers.
The Cisco Wireless LAN Controller Module is a member of the Cisco Wireless LAN controller product family. It works in conjunction with Cisco Aironet lightweight access points, the Cisco Wireless Control System (WCS), and the Cisco Wireless Location Appliance to support mission-critical wireless data, voice, and video applications.
The Cisco Wireless LAN Controller Module provides zero-touch access point deployment and configuration, making it easy for IT managers to extend secure wireless networks to branch offices. The Cisco Wireless LAN Controller Module eliminates the need to individually configure, manage, and monitor each access point. In conjunction with Cisco Lightweight Access Point Protocol (LWAPP)-enabled access points and the Cisco WCS, the Cisco Wireless LAN Controller Module minimizes deployment and operational costs, allowing businesses with limited IT staffs to easily deploy and manage wireless networks across hundreds of remote sites.
The Cisco Wireless LAN Controller Module enables enterprises to create and enforce policies that support business-critical applications. From voice and data services to location tracking, the Cisco Wireless LAN Controller Module provides the manageability and performance that IT managers require to extend their secure enterprise-class 802.11 wireless networks to branch offices (Figure 2).
The Cisco Wireless LAN Controller Module is easy to deploy and cost-effective to own and operate. It provides maximum flexibility to deploy in SMBs and in enterprise branch offices. It supports zero-touch deployments that do not require manual or pre-configuration of the access points.
When deployed with the Cisco WCS, the Cisco Wireless LAN Controller Module supports enhanced monitoring and troubleshooting features, including intuitive heat map displays, alarm filtering, event correlation, and granular reporting tools. It also supports template-based configuration management via Cisco WCS Software (optional). These intuitive templates enable the quick application of systemwide security configurations, QoS policies, mobility groups, back-end services, and other configurations via the easy-to-use, award-winning Cisco Unified Wireless Network user interface.
The Cisco Wireless LAN Controller Module is equipped with embedded software for adaptive real-time RF management. The Cisco Unified Wireless Network uses Cisco's patent-pending Radio Resource Management (RRM) algorithms that detect and adapt to changes in the air space in real time. These adjustments create the optimal topology for wireless networking in much the same way that routing protocols compute the best possible topology for IP networks. Cisco RMM creates an intelligent RF control plane for self-configuration, self-healing, and self-optimization of the wireless network (Figure 3).
Cisco RRM algorithms improve wireless LAN operations; tighten wireless security by creating a "defense shield" that helps prevent unauthorized access from outside the RF domain; and enable businesses to deploy mission-critical wireless applications such as voice.
Specific intelligent RF capabilities managed by the Cisco Wireless LAN Controller Module include:
In the Cisco Unified Wireless Network, access points simultaneously
act as air monitors and data forwarding devices. This allows access
points to communicate real-time information about the wireless
domain, including RF noise floor measurements, interference, and
potential security threats
to Cisco Wireless LAN controllers, without interrupting service. All security threats are rapidly identified and presented to network administrators via the Cisco WCS, where accurate analysis can take place and corrective action can be taken.
Cisco Systems® provides the only wireless LAN system that offers
simultaneous wireless protection and wireless LAN service delivery.
helps to ensure complete wireless LAN protection, with no unnecessary overlay equipment costs or extra monitoring devices. The Cisco Unified Wireless Network can be deployed initially as a standalone wireless IPS, and reconfigured later to add wireless LAN data service. This allows network managers to create a "defense shield" around their RF domains, containing unauthorized wireless activity until an organization is ready
to deploy wireless LAN services.
Cisco addresses wireless LAN security by offering multiple layers of protection (Figure 4), including:
The Cisco Unified Wireless Network provides best-in-class performance to support real-time applications such as voice. The Cisco Wireless LAN Controller Module enables rapid handoff between access points, providing mobility to the client. Intelligent queuing and contention management schemes provide effective resource management of the air space, helping to ensure that voice and data traffic are reliably serviced out of a single wireless network. The Cisco Wireless LAN Controller Module also supports QoS capabilities that are Wi-Fi Multimedia (WMM)-compliant and closely mirror the emerging IEEE 802.11e standard. Full compliance with the finished standard will be achieved via a software upgrade when the final standard is ratified.
The Cisco Wireless LAN Controller Module for integrated services routers allows users to roam between access points and across bridged and routed subnets without requiring changes to the underlying infrastructure. Security and QoS context information follows users wherever they roam, helping to ensure that mobility does not compromise performance, reliability, or privacy. The Cisco Wireless LAN Controller Module does not require client devices to load any special software to enable mobility (Mobile IP clients, for example).
|Integrated Into Cisco Routers|
The Cisco Wireless LAN Controller Module eliminates the need to individually configure, manage, and monitor each access point. It provides zero-touch LWAPP-enabled access point configuration and is ideal for environments with limited onsite IT support, such as branch offices within a distributed enterprise. By managing all access points as a complete wireless LAN system, the Cisco Wireless LAN Controller Module provides complete wireless LAN control and maximizes wireless LAN performance.
|Centralize Management Across Many Branches||
A single Cisco WCS can manage 100 wireless LAN controller modules located across several remote sites. The Cisco Wireless LAN Controller Module can also be managed without a Cisco WCS, using a CLI or an intuitive Web interface.
Integrated wireless intrusion prevention preserves the
integrity of wireless networks
The Cisco Wireless LAN Controller Module creates an intelligent RF control plane for self-configuration, self-healing, and self-optimization.
