Cisco UWN Architecture

With the explosion of wireless solutions in and out of the enterprise, designers must create solutions that provide mobility and business services while maintaining network security. The Cisco Unified Wireless Network (UWN) architecture combines elements of wireless and wired networks to deliver scalable, manageable, and secure WLANs. As shown in Figure 4-2, the Cisco UWN architecture is composed of five network elements:

■ Client devices—These include laptops, workstations, IP phones, PDAs, and manufacturing devices to access the WLAN.

■ Access points—These devices provide access to the wireless network. APs are placed in strategic locations to minimize interference.

■ Network unification—The WLAN system should be able to support wireless applications by providing security policies, QoS, intrusion prevention, and radio frequency (RF) management. Cisco WLAN controllers provide this functionality and integration into all major switching and routing platforms.

■ Network management—The Cisco Wireless Control System (WCS) provides a central management tool that lets you design, control, and monitor wireless networks.

■ Mobility services—These include guest access, location services, voice services, and threat detection and mitigation.
