Wireless Local Area Networks Give Users Mobility & Flexibility

By removing the limitations of wires or cables, wireless local-area networks - WLANs - allow users to define their workspaces with greater freedom and flexibility without sacrificing throughput or security.

Companies can enjoy the flexibility and cost savings offered by a line-of-sight, building-to-building bridge that avoids expensive trenches, leased lines, or right-of-way issues. Any company whose site is not conducive to LAN wiring -- older buildings, leased space, or temporary sites - can still enjoy the benefits of Ethernet and other LAN technologies.

Changes in floor plans and work spaces no longer depend on wiring constraints. Instead of using twisted-pair or fiber-optic cable, WLANs use either infrared light (IR) or radio frequencies (RF). Of the two, RF is far more popular for its longer-range, higher- bandwidth and wider coverage. Most wireless LANs today use the 2.4-gigahertz (GHz) frequency band, the only portion of the RF spectrum reserved around the world for unlicensed devices. The freedom and flexibility of wireless networking can be applied both within and between buildings.
