Cisco Aironet 350 Series — Client Adapters

Cisco Aironet 350 Series — Client Adapters
Cisco Aironet 350 Series — Client Adapters
Product Overview
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 APs. 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.

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.
Industry-Leading Centralized Security Solution for the Enterprise
For installations that need to scale to hundreds or even thousands of users, all Cisco Aironet products feature an industryleading centralized security architecture based on the IEEE 802.1x standard. Central to this architecture is the Extensible
Authentication Protocol (EAP) that enables wireless client adapter manufacturers and Remote Access Dial-In User Service
(RADIUS) server vendors to independently develop interoperable client- and server-side security software. This new security
architecture provides centralized user-based authentication integrated with network logon via utilization of an EAP-enabled
RADIUS server such as the Cisco Secure Access Control Server 2000 Version 2.6. When the user supplies a username and
password, the client interacts with the RADIUS server through a Cisco Aironet AP. When the RADIUS server authenticates
the client, the server and client negotiate a single-session, single-user encryption key and the RADIUS server transmits the
key to the AP. With this centralized and standards-based architecture, wireless security scales to meet the requirements of
any organization. Cisco Aironet 350 Series Client Adapters support the standard wired equivalent privacy (WEP) security
architecture, and include 128-bit encryption keys.
The 802.1x architecture implemented by Cisco is the first enterprise-ready security system for
WLANs.

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 AP to which they associate. This feature enables a user to use a client adapter around the world while still
maintaining regulatory compliance.
Enhanced Client Network Management Features with Extended Client Support
All Cisco wireless client adapters include the Cisco Aironet Client Utility (ACU), a tool with an intuitive graphical user
interface that makes it easy to configure, monitor, and manage an adapter. The ACU includes site-survey tools that produce
easy-to-understand, detailed graphical information, including signal strength, to assist in the correct placement of APs. The
ACU now provides improved, quantifiable data, including signal-to-noise ratio measured in decibels (dB) and signal level
and noise level measured in decibels per milliwatt (dBm). Using the ACU, a user can create a profile of settings for each

environment, such as the office or home, making it simple for telecommuters and business travelers to reconfigure the adapter
when moving from one environment to another. A user can now configure channel selection, service set identifier (SSID),
WEP key, and authentication method for these different locations. A broad suite of device drivers provides support for all
popular operating systems, including Windows 95, 98, NT 4.0, Windows 2000, Windows ME, Windows CE, Mac OS Version
9.x, and Linux.
The Preferred Client Solution for Mobile Professionals
Cisco Aironet 350 Series Client Adapters deliver superior range, reliability, and performance for business users needing
information access anytime, anywhere. Combined with Cisco Aironet unique security services, this product ensures that
business-critical information is secure. Most importantly, the Cisco client solution is easy to use, making the benefits of
wireless mobility completely transparent.
