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 standard 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-bits Wired Equivalent Privacy (WEP) encryption is used. In
addition, its standard compliance ensures that it can communicate with any 802.11b/g networks.

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.
Note: Using the 802.11g card in Ad hoc mode, your target peer can be 802.11b or 802.11g compatible wireless station. But you cannot connect to an
802.11a wireless station since 802.11a devices are not compatible with 802.11b/g devices.

Figure 1-1 Ad Hoc Mode
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.
Note: Using 802.11g card, you can connect to 802.11b or 802.11g compatible Access Point. But you cannot connect to an 802.11a Access Point since
802.11a devices are not compatible with 802.11b/g devices.

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.
