CISCO AIRONET 350 SERIES CLIENT ADAPTERS
Wireless client adapters are the key to adding mobility and flexibility to an enterprise—increasing productivity by enabling users to have network
®
and Internet access anywhere within a building without the limitation of wires. The Cisco Aironet 350 Series Client Adapters are a complement
to Aironet 350 Series infrastructure devices, providing an enterprise-ready solution that combines mobility with the performance, security, and
manageability that people have come to expect from Cisco.
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. Available in PC Card (PCMCIA) and Peripheral Component Interconnect (PCI) form factors, Cisco Aironet 350 Series Client Adapters
quickly connect desktop and mobile computing devices wirelessly to all network resources. With this product, you can instantly add new employees
to the network, support temporary workgroups, or enable Internet access in conference rooms or other meeting spaces (see Figure 1).

Client devices equipped with wireless client adapters can roam freely throughout a facility via communications with multiple access points.
ETHERNET SPEED AND IMPROVED RANGE
With a full 100 milliwatts (mW) of transmit power and the best receive sensitivity in the industry, the Cisco Aironet 350 Series Client Adapters
provide the longest range and best reliability available for wireless clients. Advanced signal processing in the Cisco Aironet 350 Series helps manage
the multipath propagation often found in office environments. Intelligent filtering addresses ambient noise and interference that can decrease
network performance. Building upon Cisco leadership in wireless LAN (WLAN) performance, the Cisco Aironet 350 Series Client Adapters provide
the greatest throughput available so users can enjoy virtually the same connectivity they gain from wire-line connections. Based on direct sequence
spread spectrum (DSSS) technology and operating in the 2.4-GHz band, the Cisco Aironet 350 Series Client Adapters comply with the IEEE
802.11b standard—ensuring interoperability with all other compliant WLAN products.
CISCO STRUCTURED WIRELESS-AWARE NETWORK
The Cisco Aironet 350 Series Client Adapter is a key component of the Cisco Structured Wireless-Aware Network (SWAN). Cisco SWAN is a
framework to integrate and extend wired and wireless networks to deliver the lowest possible total cost of ownership for companies deploying
WLANs. Cisco SWAN extends “wireless awareness” into important elements of the network infrastructure, providing the same level of security,
scalability, reliability, ease of deployment, and management for wireless LANs that organizations have come to expect from their wired LANs.
Wireless domain services (WDS) is introduced with the Cisco Structured Wireless-Aware Network. WDS is a collection of Cisco IOS Software
features that expand WLAN client mobility, simplify WLAN deployment and management and enhance WLAN security. These services—supported
®
on access points, client devices, and the Cisco Catalyst 6500 Series Wireless LAN Services Module (WLSM) today and other Cisco LAN switches
and routers in 2005—include radio management aggregation, fast secure roaming, client tracking, and WAN link remote site survivability. WDS
radio management aggregation supports radio frequency (RF) managed services such as rogue access point detection for WLAN Intrusion Detection
System (IDS), interference detection, assisted site surveys and self-healing wireless LANs. For more information on Cisco SWAN, visit:

Fast secure roaming is supported by Cisco and Cisco Compatible client devices in conjunction with Cisco Aironet, Cisco IOS Software-based 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).
Figure 2.
Fast Secure Roaming
ENTERPRISE-CLASS WIRELESS LAN SECURITY
Wireless LAN security is a primary concern. Cisco Aironet products secure the enterprise network with a scalable and manageable system featuring
the award-winning Cisco Wireless Security Suite. Based on the 802.1X standard for port-based network access, the Cisco Wireless Security Suite
takes advantage of the Extensible Authentication Protocol (EAP) framework for user-based authentication (Figure 3). This solution supports Wi-Fi
Protected Access (WPA), the Wi-Fi Alliance certification for interoperable, standards-based wireless LAN security. Cisco Aironet WPA Migration
Mode, an access point setting that enables both WPA and non-WPA clients to associate to an access point using the same SSID, is supported by the
Cisco Aironet 350 Series Client Adapter.
The Cisco Wireless Security Suite interoperates with a range of client devices. It supports all 802.1X authentication types, including Cisco LEAP,
Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling (EAP-FAST), EAP-Transport Layer Security (EAP-TLS),
Protected Extensible Authentication Protocol-Generic Token Card (PEAP-GTC), Protected Extensible Authentication Protocol-Microsoft
Challenge Handshake Authentication Protocol Version 2 (PEAP-MSCHAP V2), EAP-Tunneled TLS (EAP-TTLS) and EAP-Subscriber Identity

Module (EAP-SIM). A wide selection of Remote Access Dial-In User Service (RADIUS) servers, such as the Cisco Secure Access Control Server
(ACS), can be used for enterprise-class centralized user management. Enhanced features such as Temporal Key Integrity Protocol (TKIP) per-packet
key hashing, message integrity check (MIC) and broadcast key rotation are integral to the Cisco Wireless Security Suite.
Figure 3.
The Cisco Wireless Security Suite is an Enterprise-Class Security System Based on the 802.1X Architecture
WORLD MODE FOR INTERNATIONAL ROAMING
Cisco simplifies deployment for international travelers and multinational corporations with a new client adapter setting called world mode. When
placed in this mode, client adapters automatically inherit channel configuration properties directly from the Cisco Aironet access point to which they
associate. This feature enables a user to use a client adapter around the world while still maintaining regulatory compliance.

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.
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).

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.

Benefit
Industry-Leading Security
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)
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.
Hardware-Accelerated WEP
Encryption
Minimum degradation when encryption is enabled, resulting in maximum throughput.
Quiet Mode
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.
