Wireless Local Area Networks (WLAN)
A wireless local area network, or WLAN, is a network that enables mobile users to connect to a LAN through a wireless radio connection. Mobile devices, such as laptops or PDAs, use radio frequencies (RF) rather than cables to transport data. Components of WLANs include client adapters and access points (APs) that are configurable through software, thus providing flexibility. WLAN technology can support freestanding wireless networks or extend the range and capabilities of an existing wired network.
There are several factors that drive commercial customers to WLAN technology. Technology maturity, cost effectiveness, quality of work life, and increased productivity and accuracy are all factors. Other factors include Wi-Fi technology adoption, security compliance, and seeking a competitive edge.
