Client devices equipped with Cisco Aironet 802.11a/b/g Wireless Cardbus Adapters can roam freely throughout a facility via communications with multiple IEEE 801.11a/b/g access points
The Cisco® Aironet® IEEE 802.11a/b/g Wireless CardBus Adapter provides high-performance 54Mbps connectivity in the 2.4 and 5GHz bands. Whether configured to support single 802.11b coverage, single 802.11g coverage, single 802.11a coverage, dual-mode 802.11a/g coverage or tri-mode 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 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 is a key client-side component of the award-winning Cisco Wireless Security Suite. Based on the 802.1X standard for port-based network access, the Cisco Wireless Security Suite takes advantage of the Extensible Authentication Protocol (EAP) framework for user-based authentication. This solution also supports WPA, the Wi-Fi Alliance specification 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 Cisco LEAP, Extensible Authentication Protocol Transport Layer Security (EAP-TLS), Protected Extensible Authentication Protocol (PEAP-GTC), and Protected Extensible Authentication Protocol Microsoft Challenge Handshake Authentication Protocol Version 2 (PEAP-MSCHAP V2). A wide selection of RADIUS servers, such as the Cisco Secure Access Control Server (ACS) and Cisco Access Registrar (AR) server, can be used for enterprise-class centralized user management that includes:
Strong, mutual authentication to 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
Features:
Superior range and throughput
Secure network communications, with the Cisco Wireless Security Suite and support for Wi-Fi Protected Access (WPA)
Comprehensive utilities for flexible, easy configuration and management
World mode for international roaming
