Infrastructure Wireless LAN Configuration

For Infrastructure WLANs, multiple Access Points (APs) link the WLAN to the wired
network and allow users to efficiently share network resources. The Access Points not only
provide communication with the wired network but also mediate wireless network traffic in
the immediate neighborhood. Multiple Access Points can provide wireless coverage for an
entire building or campus. All communications between stations or between a station and a
wired network client go through the Access Point.
The Extended Service Set (ESS) shown in the next figure consists of a series of overlapping
BSSs (each containing an Access Point) connected together by means of a Distribution System
(DS). Although the DS could be any type of network, it is almost invariably an Ethernet LAN.
Mobile nodes can roam between Access Points and seamless campus-wide coverage is
possible.
