5.1.1 WLAN Overview

This section describes the concepts and application of WLAN.
Introduction to WLAN
A wireless local area network (WLAN) connects two or more computers or devices by using
the wireless telecommunication technology to provide fast Ethernet access. It allows terminals,
such as computers, to access a network through a wireless medium but not a physical cable. This
facilitates network construction and allows users to move around without interrupting
communication. Compared with a wired access network, a WLAN is easier to construct and
requires lower maintenance cost. One or more access points (APs) can provide wireless access
for a building or an area.
A WLAN uses wireless multiple access channels as the transmission media to provide LAN
services. Data is transmitted by radio waves on the WLAN. WLANs are popular on campus and
in business centers, airports, and other public areas.
WLAN Application
A WLAN system is not all wireless. The user access network is a wireless network, whereas
servers and the backbone network are deployed on a wired network.
