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.
Figure 1-2 Single BSS Network

Configuration Guide Configuring Fat AP
Multiple ESS
Multiple extended service sets (ESS) topology is used in the case of multiple logical management domains or ESS. When
a mobile subscriber joins a fat AP, it can join an available ESS. Figure 3 is the network of multiple ESS.
Figure 1-3 Multiple ESS Network

Configuration Guide Configuring Fat AP
Normally, a fat AP can provide multiple logical ESS at the same time. The fat AP broadcasts the information of ESS by
beacon packets or probe responses and help clients choose an ESS to join according to the situation.
You can configure different ESS domains on the same fat AP and enable the fat AP to announce and accept users that
have passed authentication.
Single ESS, Multiple BSS (In Case of Multi-Radio)
Figure 4 shows application of more than one radio in a single ESS. All radios support the same service set (within one
ESS), but as they belong to different BSS, the logical coverage differs.
Figure 1-4 Single ESS, Multiple BSS Network
The network of single ESS and multiple BSS is also applicable when both 802.11a and 802.11b/g are supported. Figure 4
shows two clients connecting to two radios while in the same ESS but different BSS.
