Understanding Fat AP
Figure 1-1 Typical Application of Fat AP
Overview
A fat access point (AP) is a wireless device that controls and manages wireless clients. It serves as a bridge between
the client and the local area network and forwards frames between the wired and wireless interfaces.
Working Principle
Single BSS
The area covered by an AP is called a basic service set (BSS). Each BSS is identified by a basic service set identifier
(BSSID). The simplest WLAN comprises one BSS and all wireless clients reside in the same BSS. If these clients are
granted the same authority, they can communicate with each other. Figure 2 is the network of a single BSS. These clients
can communicate with each other and also can access hosts on the network. Clients within the same BSS communicate
with each other through a fat AP.
