Chapter 1 Introduction
This Wireless LAN Card is an IEEE 802.11b Wireless LAN PCMCIA adapter. It allows your
computer to connect to a wireless network and to share resources, such as files or printers
without being bound to the network wires. Operating in 2.4GHz Direct Sequence Spread
Spectrum (DSSS) radio transmission, the Wireless LAN Card transfers data at speeds up to
11Mbps. Both Peer-to-Peer Group and Infrastructure mode are supported. For network
security concern, 64/128-bit Wired Equivalent Protection (WEP) algorithm is used. In
addition, its standard compliance ensures that it can communicate with any 802.11b networks.
This User’s Manual contains information on how to install and configure your Wireless LAN
Card. Your Wireless LAN Card will allow you to connect your computer to other Wireless
LAN Card equipped computers.

Wireless LAN Basics
This section conations some Wireless LAN basics to help you better understand how the
product work together to create a wireless network.
Local Area Network (LAN)
Simply put, a LAN is a network that exists in a relatively limited area. A network is two or
more computers connected together sharing files and peripheral devices such as printers.
The Wireless LAN Card allows you to interact with other computers without having to run
cables normally associated with networks. This lets you move your computer around while
staying connected to your network.
There are two ways to use the Wireless LAN Card. One way is to connect directly to one or
more Wireless LAN Card equipped computers, forming an Peer-to-Peer wireless network. The
second way is to connect to an Access Point that gives you access to an existing wired LAN,
forming an Infrastructure wireless network.
Chapter 1 Introduction

Peer-to-Peer Group
The Peer-to-Peer Group offers peer to peer connections between workstations, allowing
communication between computers within range that have an 802.11b DSSS compatible PC
card installed. A wireless Peer-to-Peer Group can also access a wired LAN’s TCP/IP service
(such as e-mail and the Internet) by using a TCP/IP software router on an Ethernet equipped
PowerBook or notebook.
Infrastructure Network
The infrastructure network uses an access point (or several access points) as a gateway,
linking the wireless network to a wired LAN. As a result, portable workstations or desktops on
your wireless network have access to all of the features of your wired LAN including e-mail,
Internet access, network printers and files server.
Roaming
Multiple Access Points can be installed to extend the wireless service coverage area for
seamless wireless access. Within an extended service area, all Access Points and wireless
clients must have the same Service Set Identity (SSID). Roaming among different Access
Points is controlled automatically to maintain the wireless connectivity at all times.

? MAC Address
11Mbps Wireless LAN Card User Manual
30
The MAC address for the Wireless Network Interface of the Base Station.
? SNR
The Signal-to-Noise Ratio (SNR) is the primary diagnostic counter to diagnose wireless
performance. SNR indicates the relative strength of the received Signal Level compared
to the Local Noise Level.
In most environments, SNR is a good indicator for the quality of the radio link between
transmitter and receiver. A higher SNR value means a better quality radio link. The color
coding of the SNR-bar indicates the link quality.
? AP Names
The AP Names allows you to recognize the Base Station devices in your network more
easily, instead of identifying the units by the MAC Address of the Base Station devices.
To assign an AP names to the observed MAC address, refer to “Modifying or Adding a
Name to the Base Stations List “.
? Frequency Channel
Your wireless network uses a 2.4 GHz radio that supports multiple channels.
In a Base Station network, each Wireless Client Station will automatically adopt the same
channel.
In a Peer-to-Peer Group, each Wireless Client Station will automatically adopt the
channel of workgroup. If your computer is the first station to start the workgroup, it will

Chapter 3 Wireless Client Manager
31
? Signal Level
Signal Level indicates the strength of the wireless signal as received at the Wireless
Client Adapter. As the wireless system may perform quite well even when the signal
level is low, the primary indicator to diagnose the communications quality is the level of
SNR.
? Noise Level
Noise Level reflects the level of radio interference as measured at the Wireless Client
Adapter. Noise can be indicated as Local Noise or Remote Noise.
? Local Noise: The level of radio interference as measured in the vicinity of your
wireless computer.

IP Address An IP address is a 32-bit number that identifies each sender or receiver of information sent
across the Internet. An IP address has two parts: the identifier of a particular network on the
Internet and an identifier of the particular device (which can be a server or a workstation) within
that network.
ISP Internet Service Provider. An organization that provides access to the Internet. Small ISPs
provide service via modem and ISDN while the larger ones also offer private line hookups (T1,
fractional T1, etc.).
LAN Local Area Network. A communications network that serves users within a defined
geographical area. The benefits include the sharing of Internet access, files, and equipment, such
as printers and storage devices. Special network cabling (10BaseT) is often used to connect the
PCs together.
NAT Network Address Translation. The translation of an Internet Protocol address (IP address) used
within one network to a different IP address known within another network. One network is
designated the internal network and the other is the external. The internal network then appears
as one entity to the outside world.

communicates outside of your LAN, where it is routed out to the rest of the Internet. A Subnet
Mask that has the same first three components (for example, 255.255.255.0) is the routing
pattern for a Class C address.
TCP Transmission Control Protocol. The standard transport level protocol that provides the full
duplex, stream service on which many applications’ protocols depend. TCP allows a process on
one machine to send a stream of data to a process on another. Software implementing TCP
usually resides in the operating system and uses the IP to transmit information across the
network.
WEP Wired Equivalent Privacy. The optional cryptographic confidentiality algorithm specified by
802.11. The algorithm is being used to provide data confidentiality that is subjectively
equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic
techniques to enhance privacy..
