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.
