Overview
This chapter provides an overview of the Cisco 526 Wireless Express Mobility Controller components
and features. It contains these sections:
• System Overview, page 1-1
• WLC526 Controller Overview, page 1-4
• Configuration Options, page 1-6
System Overview
The Cisco 526 Wireless Express Mobility Controller (also referred to as the WLC526 or just the
controller) is a network appliance that is optimized for secure transmission of data, voice, and video as
part of the Cisco Mobility Express solution of the Cisco Smart Business Communications System
(SBCS).
Some of the features available in the controller-based architecture of the Cisco Mobility Express
Solution include:
• Centralized management—Cisco Configuration Assistant (also referred to as CCA) enables users to
quickly and easily set-up and manage clients, access points, and network policies through a single
wizard interface and predefined configuration templates.
• Radio resource management—Features such as quality of service (QoS) and load balancing
optimize traffic of voice, video, and data, thus optimizing bandwidth.
• Up to eight virtual networks—This allows one physical infrastructure to be segmented for multiple
uses—such as by organization, security level, voice or data requirement, and so on. One network can
also be configured as a secure guest network.
• Mobility management—Allows movement from one access point to another without losing a
connection.
• Mobility services—Supports advanced mobility services traditionally reserved for enterprise
businesses, including:
– Standards-based security
– Secure guest access
– Optimized voice over Wi-Fi

System Overview
The Cisco Mobility Express Solution
The Cisco Mobility Express solution comprises access points, mobility controllers, and a configuration
assistant that is tailored to the needs of businesses with fewer than 250 employees.
Figure 1-1 shows the Cisco Mobility Express Solution elements.
Figure 1-1 Cisco Mobility Express Solution Elements
The Cisco 521 Wireless Express Access Point
The Cisco 521 Wireless Express Access Point is a single-band 802.11g access point that features
business-class management, security, and scalability. It supports high-performance wireless connectivity
in carpeted offices and similar environments. They can be deployed in two modes—standalone or
controller-based:
• Standalone (referred to as an AP521 access point)—Up to three AP521 access points can be
deployed to provide wireless connectivity between the devices and the rest of the network. In this
configuration, the access points are managed individually through the CCA.
• Controller-based (referred to as a lightweight or LAP521 access point)—Up to 12 LAP521 access
points (six per wireless LAN controller) can be deployed and become multifunctional. In addition
to offering connectivity, the access points allow the controller to monitor all wireless activities
through them. In this configuration, they are managed by the controller through the CCA.
Note Cisco 500 series access points can associate only with Cisco 500 series controllers. Because the needs
of Cisco Mobility Express customers are different than those of enterprise customers, these access points
do not operate with other controllers.
For more information about Cisco 521 Wireless Express Access Points, refer to the Quick Start Guide:
Cisco 521 Wireless Express Access Point.

Cisco 500 Series Wireless Express Mobility Controller Configuration Guide
OL-15283-01
Chapter 1 Overview
System Overview
The Cisco 526 Wireless Express Mobility Controller
The WLC526 controller is easy to deploy, use, and maintain. The CCA interface and the automated
Radio Resources Management (RRM) tool configure the access points automatically to avoid
interference or coverage gaps while maximizing the bandwidth available. If the controller detects an
access point failure or a point of interference, it immediately takes action tuning the radio power or
frequency of surrounding access points to compensate and maintain business continuity without
affecting the devices connected to the wireless network.
A single WLC526 controller supports up to six LAP521 access points. A second WLC526 controller can
be added to the network to support redundancy or to increase capacity to 12 access points, or both.
Cisco Configuration Assistant
The CCA is a PC-based user interface created specifically for small-to-medium businesses with limited
networking resources and IT expertise. CCA manages the entire Smart Business Communications
System portfolio, including Cisco Mobility Express devices (see previous section) and these SBCS
devices:
• Cisco UC500 series appliances (UC500)—The UC500 includes voice and messaging features,
Public Switched Telephone Networks and Internet connectivity, integrated network security, and an
optional integrated WLAN access point to provide basic WLAN coverage in a small office space.
• Catalyst Express 500 Series Switches (CE520)—These fixed-configuration, Layer 2-managed
Ethernet switches include wire-speed Fast Ethernet and Gigabit Ethernet connectivity, integrated
security, QoS, and Power-over-Ethernet (PoE) features.
• Cisco Unified IP Phones—The full Cisco Unified IP Phone portfolio is supported, including the
Cisco Unified IP Communicator and wireless IP phones.
Remote Configuring and Monitoring Capability
Cisco Monitor Director and Cisco Monitor Director Agent provide monitoring and reporting tools that
give network integrators real-time access to their supported customer networks. CCA supports remote
configuration. For more information about Cisco Monitor Director and Agent, refer to the Quick Start
Guide for Cisco Monitor Director 1.1 (Cisco Smart Business Communications System Release).

WLC526 Controller Overview
This section outlines the features and specifications of the WLC526 controller.
Features and Benefits
Table 1-1 lists the features and benefits of the WLC526 controller.
Table 1-1 Features and Benefits of the WLC526 controller
Features Benefits
Secure network access for guest users Secure guest access enables you to easily create and
manage a virtual guest network with a Web login
portal page for users such as customers, vendors, and
contractors. Visitors can have Internet access while
safely partitioned from the sensitive corporate LAN.
Support for Cisco voice-over-WLAN optimization Voice-over-WLAN optimization is a package of
features that deliver quality of service, call admission
control, and fast, secure inter-access-point handoff to
improve the quality of a wireless voice infrastructure.
Easy management tool Within CCA are Smart Assist features that enable
plug-and-play functionality and optimize network
settings.
Support for Cisco Lightweight Access Point Protocol
(LWAPP) Uses Cisco LWAPP for communication between
Cisco 500 series access points and WLC526
controllers to simplify deployment and management,
and to automate functions required for seamless
wireless coverage.
Support for up to 6 access points per controller and
up to 2 controllers per network for a total of 12
access points
The wireless network easily expands as business
requirements for additional wireless coverage and
mobility services increase.
Multi-access-point Radio Resource Management
(RRM) RRM automatically optimizes radio coverage and
capacity while working around potential points of
interference. This real-time radio coordination
simplifies deploying multiple access points.
Secure authentication mechanism support Supports a wide range of authentication mechanisms
to enable scalable security architectures and
minimizes security interoperability problems (see the
“Security/Authentication Standards” section on
page 1-5)
Wired/wireless network virtualization Supports the use of up to 8 SSID/VLANs so that one
physical WLAN infrastructure can be safely shared
by users, applications, or organizations with different
network and security requirements.
