Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired
systems. WLANs are flexible and easy to setup and manage. They are also more economical than
wired LAN systems.
WM821-M-LS MiniPCI Module —Introduction
2
Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs com-
bine data connectivity with user mobility. For example, users can roam from a conference room to their
office without being disconnected from the LAN.
Using WLANs, users can conveniently access shared information, and network administrators can con-
figure and augment networks without installing or moving network cables.
WLAN technology provides users with many convenient and cost saving features:
• Mobility: WLANs provide LAN users with access to real-time information anywhere in their or-
ganization, providing service opportunities that are impossible with wired networks.
• Ease of Installation: Installing is easy for novice and expert users alike, eliminating the need to
install network cables in walls and ceilings.
• Scalability: WLANs can be configured in a variety of topologies to adapt to specific applications
and installations. Configurations are easily changed and range from peer-to-peer networks suit-
able for a small number of users to full infrastructure networks of thousands of users roaming
over a broad area.

Network SSID Network SSID label (i.e., Network Name). The Network Name is a text string of up to
32 characters.
Network Type Type of environment connected to: • Infrastructure Mode In this mode, wireless clients send and receive in-
formation through APs. When a wireless client communicates with another, it transmits to the AP. First the AP
receives the information and rebroadcasts it, then other devices receive the information. The APs are strategi-
cally located within an area to provide optimal coverage for wireless clients. A large WLAN uses multiple APs to
provide coverage over a wide area. APs can connect to a LAN through a wired Ethernet connection. APs send
and receive information from the LAN through the wired connection.
