Chapter 1 Overview
This product is an IEEE 802.11b/g Wireless LAN Card with USB interface solution. This solution provides
compatibility with 802.11b and 802.11g standard devices. Now users have the flexibility to connect to
802.11b or 802.11g networks effortlessly.
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 54Mbps. BothAd hoc
and Infrastructure mode are supported. For network security concern, 64/128-bits Wired Equivalent
Privacy (WEP) encryption is used. In addition, its standard compliance ensures that it can communicate
with any 802.11b/g networks. It also supports Microsoft WHQL software for Windows XP.
Wireless LAN Basics
This section contains some Wireless LAN basics to help you better understand how the products work
together to create a wireless network.
Local Area Network (LAN)
LAN is a local network that exists in a relatively limited area. Within the network, two or more computers
are 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 anAccess Point that gives you access to an existing wired LAN, forming an Infrastructure
wireless network.
Ad Hoc Mode
An Ad Hoc network offers peer-to-peer connections between wireless stations that are in range of each
other. The stations communicate directly with each other without using an Access Point or any
connection to a wired network. This mode is useful for quickly and easily setting up a wireless network
anywhere that a wireless infrastructure does not exist or is not required for services. In an Ad Hoc
network, all wireless stations must have the same SSID, channel and WEP keys (if enabled) to
communicate with each other.

Infrastructure Mode
An Infrastructure wireless network consists of at least one Access Point connected to the wired network
infrastructure and a set of wireless end stations. The AP acts as a gateway, linking the wireless network
to a wired LAN.As a result, wireless stations have access to all of the features of your wired LAN
including e-mail, Internet, network printers and files server access.
Roaming
For large environments, multipleAccess Points can be implemented to extend the wireless service
coverage area for seamless wireless access. It allows wireless clients to roam from oneAP to another
while maintaining the wireless connectivity at all times. A wireless client wandering across multipleAPs
will automatically change the operating radio frequency as required.
In a roaming network, all APs and wireless clients must have the same Service Set Identity (SSID) and
security setting (if enabled).Alternatively the mobile station may use an SSID of “any” to associate with
any available AP, regardless of theAP’s SSID. Roaming among different Access Points is controlled
automatically to maintain the wireless connectivity at all times.
