Chapter1 Overview
System Configurations
Security Features
The Cisco Aironet Wireless LAN Client Adapter employs Direct Sequence Spread Spectrum
Technology, previously developed for military anti-jamming and low probability of intercept radio
systems.
The access point must be set to the same SSID as all other devices on the wireless infrastructure. Units
with a different SSID cannot directly communicate with each other.
System Configurations
The Cisco Aironet Wireless LAN Client Adapter can be used in a variety of network system
configurations. Access points provide connections to your Ethernet networks or act as repeaters
increasing wireless communication range. The maximum communication range is based on how you
configure your wireless infrastructure.
Examples of some common system configurations are shown on the pages that follow, along with a
description of each.
Ad Hoc Wireless LAN
An ad hoc wireless LAN (Figure 1-1) is the simplest wireless LAN configuration. In a wireless LAN,
using an ad hoc network operating system (such as Windows for Workgroups), all devices equipped with
the PC Card can be linked together and communicate directly with each other
