III
Chapter 1 Introduction
This Wireless LAN Card is an IEEE 802.11b Wireless LAN PCMCIA/USB 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 Ad-Hoc 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.
11Mbps Wireless LAN Card User's Manual
Wireless LAN Basics
This section contains 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
Ad-Hoc 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.
Ad-Hoc Mode
The Ad-Hoc Group offers peer-to-peer connections between workstations, allowing communication between computers within range that have a
Wireless LAN Card installed. A wireless Ad-Hoc network 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.
Figure 1-1 Ad-Hoc Mode
Chapter 1
Introduction
Infrastructure Mode
The Infrastructure network uses an AP or several APs 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 file
server.
Figure 1-2 Infrastructure Mode
11Mbps Wireless LAN Card User's Manual
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.
Figure 1-3 Roaming Across Multiple Access Points
Chapter 2 Installing the Wireless LAN Card
This chapter describes the installation process of the driver and software for the Wireless LAN Card. Proper driver installation is to allow the device to
operate on your host computer while the utility software, Wireless LAN Utility, is to help you configure and monitor your Wireless LAN Card.

A network composed solely of stations within mutual communication range of each other (no
Access Point connected).
Basic Service Set. A set of stations controlled by a single coordination function.
A medium used to pass protocol data units that can be used simultaneously in the same volume
of space by other channels of the same physical layer, with an acceptably low frame error ratio
due to mutual interference.
Extended Service Set. A set of one or more interconnected Basic Service Sets (BSSs) and
integrated Local Area Networks (LANs) can be configured as an Extended Service Set.
Ethernet
The most widely used medium access method, which is defined by the IEEE 802.3 standard.
Ethernet is normally a shared media LAN; i.e., all the devices on the network segment share
total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10BaseT
cables.
Gateway
A network component that acts as an entrance to another network.
IEEE 802.11
Infrastructure
The IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and
Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification for
CSMA/CD-based Ethernet networks or 802.5, the specification for token ring networks. 802.11
defines the standard for wireless LANs encompassing three incompatible (non-interoperable)
technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum
(DSSS), and Infrared. IEEE standards ensure interoperability between systems of the same
type.
A wireless network centered about an Access Point. In this environment, the Access Point not
only provides communication with the wired network but also mediates wireless network
traffic in the immediate neighborhood.

IP
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.
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.
Radio
Frequency
RF, Terms: GHz, MHz, Hz —The international unit for measuring frequency is Hertz (Hz),
equivalent to the older unit of cycles per second. One megahertz (MHz) is one Million-Hertz.
One giga hertz (GHz) is one Billion-Hertz. The standard U.S. electrical power frequency is 60
Hz, the AM broadcast radio frequency band is 0.55–1.6 MHz, the FM broadcast radio
frequency band is 88–108 MHz, and wireless 802.11 LANs operate at 2.4GHz.
SSID
Service Set ID. A group name shared by every member of a wireless network. Only client PCs
with the same SSID are allowed to establish a connection.
Subnet Mask
A value that defines whether your computer communicates only within your LAN or
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
44
Internet Protocol. The standard protocol within TCP/IP that defines the basic unit of
information passed across an Internet connection by breaking down data messages into packets,
routing and transporting the packets over network connections, then reassembling the packets
at their destination. IP corresponds to the network layer in the ISO/OSI model.
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..
