MODEL- AIR-CB21AG-A-K9    VENDOR- CISCO

FEATURES- Cisco Aironet 802.11A/B/G Wireless Cardbus Adapter
       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.
       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
* Cisco Wireless Security Suite
   IEEE 802.1X support, including Cisco LEAP, PEAP-GTC, PEAP-MSCHAPv2, and
   EAP-TLS for mutual authentication with dynamic per-user, per-session
   encryption keys via TKIP enhancements. Full support for WPA. Ready for
   IEEE 802.11i/WPA2 AES support.
* Enhanced Client Network Management
   Bundled with comprehensive, easy-to-use client network management
   utilities to provide a secure, intuitive, and convenient way to manage
   and configure the adapter.
* Cisco LEAP Single Sign-on
   Convenient option to use login credentials for LEAP sign-on on the
   users network, eliminating the need to enter a second set of
   credentials.
* Cisco Wireless Domain Services (WDS)
   Cisco WDS is a collection of Cisco IOS  Software features that enhance
   wireless LAN client mobility and simplify wireless LAN deployment and
   management. Cisco WDS includes radio management aggregation, fast secure
   roaming, client tracking, and WAN link remote site survivability.
* Site Survey Utility
   The site survey utility can assist in conducting site surveys, as well
   as troubleshooting existing RF wireless LANs. The utility operates at
   the RF level and is used to determine the best placement and coverage
   (overlap) for the network's infrastructure devices.
* Fast Secure Roaming
   Allows authenticated client devices to roam securely from one access
   point to another, within or across subnets, without any perceptible
   delay during reassociation. Provides support for latency-sensitive
   applications such as voice over IP (VoIP), enterprise resource planning
   (ERP), and Citrix.
