Increased mobility is the major motivation and benefit from Wireless LAN
ByA wireless local area network (WLAN) is a flexible-data communications system implemented as an extension to or as an alternative for, a wired LAN. Using Radio Frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the need for wired connections. Much like base stations for cellular technology, WLANs use Access Point (AP) to provide wireless access to mobile terminals (MTs) or other devices in the network. These APs are either connected to other APs, to other wired networks such as Ethernet or connected to a broadband access medium such as DSL, cable, T1, etc.
The major motivation and benefit from Wireless LANs is increased mobility. Undeterred from conventional network connections, network users can move about almost without restriction and access LANs from nearly anywhere. The other advantages for WLAN include cost-effective network setup for hard-to-wire locations such as older buildings and solid-wall structures and reduced cost of ownership-particularly in dynamic environments requiring frequent modifications, thanks to minimal wiring and installation costs per device and user. WLANs are a rapidly emerging market.
WLANs liberate users from dependence on hard-wired access to the network backbone, giving them anytime, anywhere network access. This freedom to roam offers numerous user benefits for a variety of work environments and business sectors, through that WLANs have a strong popularity in vertical markets such as telecommuting, SOHOs (Small Office/Home Office), health-care, retail, manufacturing, warehousing, and academia, where productivity gains are realized by using hand-held terminals and notebook PCs to transmit real-time information to centralized hosts for processing.
