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. 2.2 Ad-Hoc M o d e The Ad-Hoc mode 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. Figure 1-1 Ad-Hoc Mode Wireless CF Card User Manual 2.3 Infrastruct u r e 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 2.4 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.
