Data Sheet Cisco Aironet 802.11A/B/G Wireless CardBus Adapter 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 connectivity 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 Adapter 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 All contents are Copyright © 1992-2007 Cisco Systems, Inc.
