The Cisco

Aironet

802.11a/b/g Wireless CardBus Adapter provides high-performance 54-Mbps connectivity in the 2.4-

and 5-GHz bands.

Whether configured to support single 802.11b coverage, single 802.11g coverage, single 802.11a coverage, dual-mode 802.11a/g coverage, or

trimode 802.11a/b/g coverage, the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter is Wi-Fi-compliant and combines the freedom of wireless

ENTERPRISE-CLASS SECURITY SOLUTION

Designed with enterprise-class security requirements in mind, the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter uses the 802.1X standard for

port-based network access. A full array of Extensible Authentication Protocol (EAP) types for user-based authentication, together with enterprise-

caliber Advanced Encryption Standard (AES) encryption, provide full 802.11i support. The adapter supports WPA2—the Wi-Fi Alliance

certification for interoperable, standards-based wireless LAN security.

The Cisco Aironet 802.11a/b/g Wireless CardBus Adapter supports the most common 802.1X authentication types, including EAP-Flexible

Authentication via Secure Tunneling (EAP-FAST), Cisco LEAP, EAP-Transport Layer Security (EAP-TLS), Protected Extensible Authentication

Protocol-Generic Token Card (PEAP-GTC), and PEAP-Microsoft Challenge Handshake Authentication Protocol version 2 (PEAP-MSCHAPv2). A

wide selection of RADIUS servers, such as the Cisco Secure Access Control Server (ACS) and Cisco Access Registrar server, can be used for

enterprise-class centralized user management that includes:

• Strong, mutual authentication to help ensure that only legitimate clients associate with legitimate and authorized network RADIUS servers via

authorized access points

• Dynamic per-user, per-session encryption keys that automatically change on a configurable basis to protect the privacy of transmitted data

• Stronger encryption keys provided by Temporal Key Integrity Protocol (TKIP) enhancements such as message integrity check (MIC), per-packet

keys via initialization vector hashing, and broadcast key rotation

• RADIUS accounting records for all authentication attempts

• IEEE 802.11i/WPA2 AES support
