Cisco Aironet 802.11A/B/G Wireless PCI Adapter

The Cisco

Aironet

802.11a/b/g Wireless PCI 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 PCI 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).

The low-profile form factor and two-meter cable length provide significant flexibility for installation

in low-profile devices, such as slim desktops and point-of-sale (POS) devices. For versatility, both

a low profile and a standard profile bracket frame are included with the adapter. The attached

dual-band, 2.4/5-GHz, 1-dBi effective gain antenna has a two-meter cable that enables optimal

placement for maximum performance.

Enterprise-Class Security Solution

Designed with enterprise-class security requirements in mind, the Cisco Aironet 802.11a/b/g

Wireless PCI 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 PCI 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.
