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.
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.

11Mbps Wireless LAN Card User's Manual
Wire les s 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 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 Network
The Ad Hoc network offers peer to peer connections between workstations, allowing
communication between computers within range that have an 802.11b DSSS compatible PC

Chapter 1 Introduction
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.
Infras tructu re N e tw o rk
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.

An IEEE standard (802.3) for operating 10 Mbps Ethernet networks (LANs) with twisted pair
cabling and a wiring hub.
An internetworking device that seamlessly connects wired and wireless networks. Access Points
combined with a distributed system support the creation of multiple radio cells that enable
roaming throughout a facility.
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.
An Ethernet address mode that treats the entire Ethernet packet as a whole and places it inside
an 802.11 frame along with a new header.

IP Address
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.
A network component that acts as an entrance to another network.
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.
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.
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
geograp
t ha t ne t w o rk.
Internet Service Provider. An organization that provides access to the Internet. Small ISPs
ISP
provide service via modem and ISDN while the larger ones also offer private line hookups (T1,
fractional T1, etc.).

LAN
NAT
Local Area Network. A communications network that serves users within a defined
hical 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.
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.

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 frequenc
band is 88–108 MHz, and wireless 802.11 LANs operate at 2.4GHz.
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.
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.
Transmission Control Protocol. The standard transport level protocol that provides the full

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.
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..
