Data Sheet

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 peerto-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 802.11i, Wi-Fi

Protected Access 2 (WPA2), WPA, and numerous Extensible Authentication Protocol (EAP) types. WPA and WPA2 are the Wi-Fi Alliance certifications for interoperable, standards-based WLAN security. These certifications support IEEE 802.1X for user-based authentication, Temporal

Key Integrity Protocol (TKIP) for WPA encryption, and Advanced Encryption Standard (AES) for WPA2 encryption. These certifications help to ensure interoperability between Wi-Fi-certified WLAN devices from different manufacturers.

Figure 1. Client devices equipped with 802.11a wireless client adapters can roam freely throughout a facility via communications with multiple IEEE 802.11a access points and dual-mode access points.

FAST SECURE ROAMING

Fast secure roaming is supported by Cisco and Cisco Compatible client devices in conjunction with Cisco Aironet access points. With fast secure roaming, authenticated client devices can roam securely from one access point to another, within or across subnets, without any perceptible delay during reassociation. Fast secure roaming supports latency-sensitive applications such as wireless voice over IP (VoIP), enterprise resource planning

(ERP), or Citrix-based solutions (Figure 2).

Cisco Aironet 5 GHz Wireless LAN Client Adapter. Enhanced client network management features include:

Site-survey tools—Easy-to-understand detailed graphical information to assist in the placement of access points (Figure 3)

Troubleshooting facility—Step-by-step details on the process of connecting to an access point that highlights why a connection failed (Figure 4)

Profile Manager—Create specific profile settings for various environments, such as the office or home, making it simple for telecommuters and business travelers to move from one environment to another

Customized Profile settings—Individually select channel, service set identifier (SSID), WEP key, and the authentication method for different locations

Cisco LEAP authentication status screen—Status updates regarding the Cisco LEAP authentication process

Autoselection of Cisco LEAP profile—Automatic selection of a Cisco LEAP profile without having to store the Cisco LEAP username and password in the profile

System Tray icon—Easy access to wireless LAN connection information and one-click access to common actions such as selecting the right profile for a wireless LAN (Figure 5)

Client firmware, drivers, utilities and security modules are easily installed using the Cisco Aironet Wireless LAN Client Adapter Installation Wizard for Microsoft Windows operating systems. The wizard can run in an interactive mode or in an automated “silent mode” without user interaction, triggered by existing IT software distribution tools. The wizard image file is a self-extracting executable (.exe) file (Figure 6).

ENTERPRISE-CLASS PERFORMANCE

Cisco’s innovative radio and antenna design delivers industry-leading 802.11a enterprise performance. It provides for maximum capacity and scalability across the enterprise through eight non-overlapping channels in the UNII-1 and UNII-2 bands. The integrated 5 dBi gain patch antenna optimizes range. The –68 dBm receive sensitivity at 54 Mbps provides high-data-rate range performance. Advanced signal processing in the Cisco

Aironet 5 GHz Wireless LAN Client Adapter helps manage the multipath propagation often found in office environments and intelligent filtering addresses ambient noise and interference that can decrease network performance. Various transmit power settings on the Cisco Aironet client adapter enable you to select range capabilities.

Industry-Leading Security

Benefit

WPA Certified Cisco Wireless Security Suite includes IEEE 802.1X mutual authentication with Cisco

LEAP, EAP-FAST, PEAP-GTC, PEAP-MSCHAP V2, EAP-TLS and EAP-SIM, Cisco TKIP, and WPA

TKIP support.

Multiple Transmit Power Settings

(20 mW/(13 dBm), 10 mW/(10 dBm), and 5 mW (7 dBm)

Hardware-Accelerated

WEP Encryption

Quiet Mode

Provides flexibility to limit RF coverage. Multiple transmit power settings are especially useful when coupled with one of the broad antenna offerings to direct or limit RF coverage.

Minimum degradation when encryption is enabled, resulting in maximum throughput.

Forces the client adapter to become quiet (to passively scan or listen) when its associated access point is turned off. The client generates radio frequency energy only in direct response to an access point transmission. It applies to individual cards rather than profiles and can be set differently for different cards remaining in effect across Aironet Client Utility sessions and computer reboots.
