This Wireless LAN Card is an IEEE 802.11b Wireless LAN 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.
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.
L
Lo oc ca al l A Ar re ea a N Ne et tw wo or rk k ( (L LA AN N) )
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.
A
Ad d H Ho oc c N Ne et tw wo or rk k
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 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 on an
Ethernet equipped PowerBook or notebook.
I
In nf fr ra as st tr ru uc ct tu ur re e N Ne et tw wo or rk k
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.
R
Ro oa am mi in ng g
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.
