2 Network Configuration and Planning 2.1 Wireless LAN Basic The WLANs supports legacy Ethernet LAN network configuration options as defined by the IEEE 802.11b standards committee. The wireless LAN CardBus PC card can be configured as: ．Ad-Hoc for departmental or SOHO LANs. ．Infrastructure for enterprise LANs. ．LAN-Interconnection for point-to-point link as campus backbone. 2.
Infrastructure Wireless LAN The adapter provides access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an infrastructure configuration. A group of WLAN PC users and an Access Point compose a Basic Service Set (BSS). Each WLAN PC in a BSS can talk to any computer in the wired LAN infrastructure via the Access Point.
The use of a unique ID in a BSS is essential. All WLAN equipped PCs configured without roaming options in independent BSS must be configured with a BSS ID corresponding to the Access Point used in the BSS. Check your Access Point for its BSS ID or use the Access Point Browser Utility program to determine the BSS ID. The infrastructure wireless LAN configuration is appropriate for enterprise-scale wireless access to a central database, or as a wireless application for mobile users. 2.
