A wireless LAN (WLAN) is a cellular computer network that facilitates
communication with radio signals instead of wires. Wireless LANs are used
increasingly in both home and corporate environments. Innovative ways to
utilize WLAN technology are helping people to work and communicate more
efficiently. Increased mobility and the absence of cabling and other fixed
infrastructure has proven to be beneficial for many users.
WLAN users can use the same network applications they use on an Ethernet
LAN. WLAN adapter cards used on laptop and desktop systems, support the
same protocols as Ethernet adapter cards. For most users, there is no
noticeable functional difference between a wired Ethernet desktop computer
or mobile WLAN workstation other than the added benefit of the ability to
roam within the WLAN-cell. Under many circumstances, it may be desirable
for mobile network devices to link to a conventional Ethernet LAN in order
use servers, printers or an Internet connection supplied through the wired
LAN. The Wireless Access Point is a device used to provide this link.
People use wireless LAN technology for many different purposes.
