• Secure Mobility—Maintains the highest level of security in mobile environments with Cisco Proactive Key Caching (PKC), an extension to the

802.11i standard and precursor to the 802.11r standard that facilitates secure roaming with Advanced Encryption Standard (AES) encryption and

RADIUS authentication.

• Guest Tunneling—Provides additional security for access to the corporate network by guest users. It helps ensure that guest users are only able

to access the corporate network by passing through the corporate firewall.

Real-Time Application Support

The Cisco Unified Wireless Network provides best-in-class performance to support real-time applications such as voice. Cisco WiSM enables

rapid handoff between access points and multiple modules and/or controllers, providing smooth mobility with no interruption in service to the client.

Intelligent queuing and contention management schemes provide effective resource management in the air space. The Cisco WiSM 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.

Mobility

The Cisco WiSM 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 WiSM does not require any modifications to existing infrastructures or client devices to enable

mobility (mobile IP, for example).
