Cisco Aironet 5 GHz 54 Mbps Wireless LAN
Client Adapter (CB20A)

The Cisco Aironet

5 GHz 54 Mbps Wireless LAN client adapter is an Institute of

Electrical and Electronic Engineers (IEEE) 802.11a-compliant CardBus adapter that

operates in the UNII-1 and UNII-2 bands. The client adapter combines performance

and mobility with the security and manageability that enterprises require.

Wireless LAN client adapters can increase productivity by enabling mobile users to have

network and Internet access anywhere within a building that is equipped with a wireless network

infrastructure. Wireless client adapters connect a variety of devices to a wireless network either in

ad hoc peer-to-peer mode or in infrastructure mode with access points. With this client adapter,

you can quickly add new employees to a network, support temporary workgroups, or enable

Internet access in conference rooms or other meeting spaces (Figure 1). And the Cisco Aironet

client solution is easy to use, making the benefits of wireless mobility completely transparent.

Enterprise-Class Security

The Cisco Aironet 5 GHz Wireless LAN Client Adapter is part of the award-winning Cisco Wireless

Security Suite, which supports WPA and numerous Extensible Authentication Protocol (EAP)

types. WPA is the Wi-Fi Alliance certification for interoperable, standards-based WLAN security.

These certifications support IEEE 802.1X for user-based authentication, Temporal Key Integrity

Protocol (TKIP) for WPA encryption. These certifications help to ensure interoperability between

Wi-Fi-certified WLAN devices from different manufacturers.
