Access Point AP Peer-to-Peer Ad Hoc Wireless LAN WLAN Ethernet network LAN network This Users Manual contains information on how to install and configure your Wireless LAN Card. From now on, we will guide you through the correct configuration steps to get your device up and run. V Chapter 1 Introduction This Wireless LAN Card is an IEEE 802.11b Wireless LAN (Mini-)PCI 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, 40/104-bit Wired Equivalent Privacy (WEP) algorithm is used. In addition, its standard compliance ensures that it can communicate with any 802.11b networks. 1 11Mbps Wireless LAN Card User's Manual 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. 2 Chapter 1 Introduction 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 LANs TCP/IP service (such as e-mail and the Internet) by using a TCP/IP software router on an Ethernet equipped PowerBook or notebook. Figure 1-1 Ad-Hoc Mode 3 11Mbps Wireless LAN Card User's Manual 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. Figure 1-2 Infrastructure Mode 4 Chapter 1 Introduction 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.
