Q: What is a Wireless LAN (WLAN)? A: A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and transmit data. It is a flexible data communication system implemented as an extension to or as an alternative for, a wired LAN. Q: What are the benefits of using a WLAN instead of a wired network connection? A: l Increased Productivity - WLAN provides "untethered" network and Internet access. l Fast and Simple Network Set-up - There are no cables to install at a users desk or work area. l Installation Flexibility - WLANs can be installed in places where wires can't, and they facilitate temporary set-up and relocation. l Reduced Cost-of-Ownership - Wireless LANS reduce installation costs because there is no cabling; as a result, savings are greatest in frequently changing environments. l Scalability - Network expansion and reconfiguration may be less complicated than expanding a wired network, Q: Are Intel WLAN products interoperable with other product brands? A: Yes. Intel WLAN products are compatible with products from different vendors employing the same technology (i.e., IEEE 802.11a, 802.11b, or 802.11g); Choosing products that are Wi-Fi* certified will help insure compatibility Q: What is Wi-Fi*? A: Wi-Fi* is the trademarked name that the Wi-Fi Alliance uses to signify WLAN product interoperability. The name stands for "wireless fidelity." Wi-Fi Alliance performs elaborate tests on WLAN products and those that pass the tests are awarded the Wi-Fi logo.
