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
connectivity with 802.11i/Wi-Fi Protected Access 2 (WPA2) encryption for the performance,
security, and manageability that businesses require (Figure 1).

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.
Support for Management Frame Protection (MFP) is now available on the Cisco Aironet
802.11a/b/g Wireless CardBus Adapter. MFP adds security to the MAC management layer
of 802.11 connectivity by cryptographically hashing the management frames and generating
a Message Integrity Check (MIC) during network connection.
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
