Configuration Guide Configuring FAT APs
Figure 1-2
Radio1 is the first RF interface of the FAT AP.
Client1 and Client2 are wireless clients.
The FAT AP and Client1 comprise BSS1 and BSS1 belongs to ESS1.
The FAT AP and Client2 comprise BSS2 and BSS2 belongs to ESS2.
Deployment
Run the IEEE802.11 protocol on the FAT AP, Client1 and Client2 to implement access and authentication of the
wireless clients.
Configure and manage the FAT AP.
Run 802.11a or 802.11b on the FAT AP because the FAT AP provides only Radio 1.
Create two WLANs on the FAT AP, namely, ESS1 and ESS2. Both the two WLANs are mapped to Radio1, namely
BSS1 and BSS2.
1.2.3 Configuring Single ESS and Multiple BSSs (Multiple RF Bands)
Scenario
A FAT AP may support more than one band in a single logic management domain. All bands support the same ESS, but
belong to different BSSs; therefore, their physical coverage ranges are different. This networking also applies to scenarios
where both 802.11a and 802.11b/g need to be supported.
As shown in Figure 1-3, Client1 accesses the 2.4 GHz band, and Client2 accesses the 5 GHz band. Client1 and Client2
belong to the same ESS1, but Client 1 belongs to BSS1 and Client2 belongs to BSS2.
