Cisco Aironet 340 Series Client Adapters and Access Points

Product Overview

The Cisco Aironet 340 Series is a comprehensive family of client adapters and access points that enables organizations to integrate the freedom and flexibility of wireless local-area networking into their information systems.

The Cisco Aironet 340 Series offers

11 Mbps Performance
Security equivalent to wired networks
Wireless freedom and flexibility
IEEE 802.11b interoperability

The Cisco Aironet 340 series client adapters and access points are designed to meet the mobility, performance, security, interoperability/management, and reliability requirements of in-building wireless local-area networks (WLANs) within enterprise-wide information infrastructures or as free standing all-wireless networks. The Aironet 340 series products provide value-added features that are ideal for:

IT professionals or business executives who want mobility within the enterprise, as an addition or alternative to wired networks
Business owners or IT directors who need flexibility for frequent LAN wiring changes, either throughout the site or in selected areas
Any company whose site is not conducive to LAN wiring because of building or budget limitations, such as older buildings, leased space, or temporary sites

Key Features and Benefits

The Cisco Aironet 340 series is a comprehensive family of client adapters1 and access points2 that enables organizations to integrate the freedom and flexibility of wireless local-area networking into their information systems.

The Aironet 340 series includes a complete line of client adapters, including PC Card, Personal Computer Interface (PCI), and Industry-Standard Architecture (ISA) cards for both notebook and desktop wireless connectivity. Aironet 340 series access points offer unprecedented management features, including a full-featured Web interface to simplify the navigation of the network, and a variety of antenna options to fit virtually any environment.

Based on direct sequence spread spectrum (DSSS) 3 technology and operating in the 2.4 GHz band, the Aironet 340 series provides an Ethernet-like data rate of up to 11 megabits per second (Mbps). The high speed and throughput of the Aironet 340 series enables the wireless transfer of bandwidth-intensive data such as multimedia streams and large data files within the enterprise.

Understanding the security requirements of both small businesses and the enterprise, Cisco provides up to 128-bit Wired Equivalent Privacy (WEP), an optional security mechanism defined within the 802.11 standard that is designed to make the link integrity of the wireless medium equal to that of a cable. WEP is integrated with standard authentication features, providing a level of data security equal to traditional wired LANs.

For investment protection, the Aironet 340 series conforms to the IEEE 802.11b standard, ensuring interoperability with equipment available from a variety of vendors. The Aironet 340 series is fully compatible with most popular network operating systems and delivers both Simple Network Management Protocol (SNMP) and Web-based management features. The Aironet 340 series can be seamlessly integrated into wired Ethernet networks, as a complement or alternative to the best-of-class wired LAN products offered by Cisco Systems.

Aironet 340 Series Client Adapter

Cisco Aironet 340 series client adapters couple the mobility, freedom, and flexibility of wireless local-area networking with the bandwidth required by enterprise-wide information systems. With wireless-enabled client PCs, users with laptop, notebook, and hand-held devices can move freely within a campus environment while maintaining uninterrupted access to centrally located data. With wireless PCI and ISA adapters, desktop PCs can be quickly added to a LAN without expensive, time-consuming, and often impractical cable runs and drops. With wireless, as an organization grows, reorganizes, or even changes location, clients can be quickly relocated without a loss of productivity.

Now with 11 Mbps of bandwidth,5 the benefits of wireless do not come at the expense of the data rate and throughput required by data-intensive applications. With the Cisco client adapters, users don`t sacrifice anything; they experience the network performance they have come to expect — without the constraints and inflexibility of a wired connection.

All Aironet 340 series adapters feature antennas that provide the range and reliability required for data transmission and reception in larger indoor facilities. The internal dual diversity antennas6 of the PC adapter automatically toggle to select the antenna receiving the strongest signal as the user moves within a facility. The fixed, integrated antenna is rugged enough to withstand the rigors of mobile computing and compact enough to stay out of the way, extending only an inch outside the PC Card slot. The external antenna, standard with the PCI and ISA adapters, is optimized for transmission from a stationary system and fits neatly behind the PC.

Up to 128-bit wired equivalent privacy (WEP) encryption security is available to provide data security that is comparable to traditional wired LANs. Cisco includes a complete set of device drivers to make installation trouble-free in a full range of systems. Easy-to-use site survey tools produce graphical information, including signal strength. To further facilitate installation, Cisco provides a suite of integrated utilities for Windows-based configuration, management, and diagnostics.

Aironet 340 Series Access Points

Cisco Aironet 340 series access points perform functions similar to a hub in a wired network; in addition, they add the vital, price/performance benefits of security, management features, and mobility services. For example, the innovative roaming functionality provided by Aironet access points enable users equipped with wireless client adapters to freely move throughout a facility while maintaining seamless, uninterrupted access to the network. The Aironet 340 family of access points features easy integration to a wired network backbone, flexible configuration, management capabilities, and a wide range of product configurations.

The Aironet 340 series access points integrate easily into 10 and 100 Mbps Ethernet networks via a single autosensing RJ-45 port. The access point acts as a bridge, forwarding at media speed between the Ethernet CSMA/CD protocol and the wireless CSMA/CA protocol, seamlessly integrating wireless functionality into a wired infrastructure. The Aironet 340 series access points may be configured locally via serial port or remotely over the LAN; they provide the option of a Web browser or console management interface.

The Aironet 340 management system offers IS professionals complete control over access-point settings and operational information. Setting security levels, addresses, transmission channels, data rates, and other options can be done quickly through either management interface. The management system captures vital operational data that may be viewed as an event log within the management system or exported to a Management Information Base (MIB) for analysis by an SNMP-compliant system.

Every in-building wireless deployment presents different transmission considerations: varying building sizes, construction materials, and interior divisions impact the deployment of a wireless LAN. To ensure maximum network coverage efficiency in a variety of information systems and facilities, Cisco offers access points with three distinct antenna configurations. For small to medium-sized businesses and similar organizations, Cisco provides an access point with a single, integrated, external antenna that is designed to combine needed features with more stringent budget requirements. For larger organizations, Cisco provides access points with integrated, dual-diversity, external antennas that address the multipath7 problems associated with larger facilities. Finally, for the most challenging installations, Cisco provides access points with dual reverse polarity8 TNC connectors. These connectors allow the planner to select from more than 20 different omnidirectional, patch, yagi, and parabolic antennas to engineer the coverage needed within almost any facility. To meet the security needs of organizations around the world, access points are available with up to WEP-128 encryption.
