Руководство По Проектированию для Cisco Cisco Aironet 350 Mini-PCI Wireless LAN Client Adapter

The flexibility of Cisco Unified Wireless LAN solution leads to the following choices about where to 
locate WLCs:

Distributed WLC deployment—In the distributed model, WLCs are located throughout the campus 
network, typically on a per building basis, managing the APs that are resident in a given building. 
The WLC(s) is connected to the campus network using the distribution routers within the building. 
In this scenario the LWAPP tunnels, between APs and the WLC typically stay within the building. 

 shows a distributed WLC deployment.

Each of the distributed WLCs could be configured with as a separate RF group and mobility group, 
so long as the WLAN coverage is not overlapping between buildings.

Centralized WLC deployment—In this model, WLCs are placed at a centralized location in the 
enterprise network. This deployment model requires the AP/WLC LWAPP tunnels to traverse the 
campus backbone network. An example of a centralized WLC deployment is shown in 

Note in the example below that the centralized WLCs (a pair of WiSMs in Catalyst 6500's) are not 
shown in a specific building. A centralized WLC cluster is connected via a dedicated switch block
