Page 1 of 7Cisco Aironet 802.11A/B/G Wireless CardBus AdapterThe Cisco® Aironet® 802.11a/b/g Wireless CardBus Adapter provides high-performance54-Mbps connectivity in the 2.4- and 5-GHz bands.Whether configured to support single 802.11b coverage, single 802.11g coverage, single 802.11acoverage, dual-mode 802.11a/g coverage, or trimode 802.11a/b/g coverage, the Cisco Aironet802.11a/b/g Wireless CardBus Adapter is Wi-Fi-compliant and combines the freedom of wirelessconnectivity with 802.11i/Wi-Fi Protected Access 2 (WPA2) encryption for the performance,security, and manageability that businesses require (Figure 1).Figure 1. The Cisco Aironet 802.11a/b/g Wireless CardBus AdapterEnterprise-Class Security SolutionDesigned with enterprise-class security requirements in mind, the Cisco Aironet 802.11a/b/gWireless CardBus Adapter uses the 802.1X standard for port-based network access. A full arrayof Extensible Authentication Protocol (EAP) types for user-based authentication, together withenterprise-caliber Advanced Encryption Standard (AES) encryption, provide full 802.11i support.The adapter supports WPA2, the Wi-Fi Alliance certification for interoperable, standards-basedwireless LAN security.Support for Management Frame Protection (MFP) is now available on the Cisco Aironet802.11a/b/g Wireless CardBus Adapter. MFP adds security to the MAC management layerof 802.11 connectivity by cryptographically hashing the management frames and generatinga Message Integrity Check (MIC) during network connection.The Cisco Aironet 802.11a/b/g Wireless CardBus Adapter supports the most common 802.1Xauthentication types, including EAP-Flexible Authentication via Secure Tunneling (EAP-FAST),Cisco LEAP, EAP-Transport Layer Security (EAP-TLS), Protected Extensible AuthenticationProtocol-Generic Token Card (PEAP-GTC), and PEAP-Microsoft Challenge HandshakeAuthentication 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 associatewith legitimate and authorized network RADIUS servers via authorized access points● Dynamic per-user, per-session encryption keys that automatically change on a configurablebasis to protect the privacy of transmitted data
