Cisco Wireless Solution is designed to provide 802.11 wireless networking solutions for enterprises and service providers. Cisco Wireless Solution simplifies deploying and managing large-scale wireless LANs and enables a unique best-in-class security infrastructure. The operating system manages all data client, communications, and system administration functions, performs radio resource management (RRM) functions, manages system-wide mobility policies using the operating system security solution, and coordinates all security functions using the operating system security framework.
This figure shows a sample architecture of a Cisco Wireless Enterprise Network:
The interconnected elements that work together to deliver a unified enterprise-class wireless solution include:
Access points (APs)
Network unification through Cisco Wireless Controllers (WLCs)
Beginning with a base of client devices, each element adds capabilities as the network needs to evolve and grow, interconnecting with the elements above and below it to create a comprehensive, secure WLAN solution.
A Cisco Wireless network consists of the following core components:
Cisco Wireless Controllers—Controllers are enterprise-class high-performance wireless switching platforms that support 802.11a/n/ac and 802.11b/g/n protocols. They operate under control of the operating system, which includes the radio resource management (RRM), creating a Cisco Wireless solution that can automatically adjust to real-time changes in the 802.11 RF environment. Controllers are built around high-performance network and security hardware, resulting in highly reliable 802.11 enterprise networks with unparalleled security.
The following controllers are supported:
Cisco Aironet Access Points (APs)—Cisco Aironet series wireless access points can be deployed in a distributed or centralized network for a branch office, campus, or large enterprise. For more information about APs, see https://www.cisco.com/c/en/us/products/wireless/access-points/index.html
Cisco Prime Infrastructure (PI)—Cisco Prime Infrastructure can be used to configure and monitor one or more controllers and associated APs. Cisco PI has tools to facilitate large-system monitoring and control. When you use Cisco PI in your Cisco wireless solution, controllers periodically determine the client, rogue access point, rogue access point client, radio frequency ID (RFID) tag location and store the locations in the Cisco PI database. For more information about Cisco PI, see http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-infrastructure/tsd-products-support-series-home.html.
Cisco Connected Mobile Experiences (CMX) / Cisco Mobility Services Engine (MSE)—Cisco Mobility Services Engine (MSE) acts as a platform to deploy and run Cisco Connected Mobile Experiences (Cisco CMX). Cisco MSE is delivered in two modes—the physical appliance (box) and the virtual appliance (deployed using VMware vSphere Client) . Using your Cisco wireless network and location intelligence from Cisco MSE, Cisco CMX helps you create personalized mobile experiences for end users and gain operational efficiency with location-based services. For more information about Cisco CMX/Cisco MSE, see https://www.cisco.com/c/en/us/support/wireless/connected-mobile-experiences/tsd-products-support-series-home.html.

Overview of Cisco Mobility Express
The Cisco Mobility Express wireless network solution comprises of at least one 802.11ac Wave 2 Cisco Aironet Series access point (AP) with an in-built software-based wireless controller managing other APs in the network.
The AP acting as the controller is referred to as the master AP while the other APs in the Cisco Mobility Express network, which are managed by this master AP, are referred to as subordinate APs.
In addition to acting as a controllers, the master AP also operates as an AP to serve clients along with the subordinate APs.
Cisco Mobility Express provides most features of a controllers and has the capability to interface with the following:
Cisco Prime Infrastructure—For simplified network management, including managing AP groups
Cisco Identity Services Engine—For advanced policy enforcement
Connected Mobile Experiences (CMX)—For providing presence analytics and guest access using Connect & Engage
