Chapter 1 Introduction
This Wireless LAN Card is an IEEE 802.11g wireless LAN adapter. 802.11g is the latest in
the series of 802.11 specifications for wireless local area networks (WLANs) and provides
data transfer of up to 54 Mbps.Since 802.11g operates on the same frequency of 2.4 GHz as
802.11b, so it is backwards compatible with existing Wi-Fi devices!
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. 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/g networks.

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 networkthat 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 LANCard 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 LANCard. 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.
