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.
