Link Unified Access System Topology | D-Link DWS 3000 instruction

1 Overview of the D-Link Unified Access System

Figure 1 shows an example of a floor plan and network with a D-Link WLAN Controller Switch that manages two APs. The graph also shows a peer switch and a rogue AP in the network.

Figure 1. Sample WLAN Visualization

The WLAN Visualization tool provides an AP power display with color-coded channels to help you determine where to physically place access points to reduce interference or increase coverage on your WLAN.

D-Link Unified Access System Topology

The WLAN network topology you use depends on the size and requirements of your network. Small-to-medium networks might require only one WCS that manages a few D-Link Access Points. For larger networks that need greater roaming capabilities for wireless clients, a deployment with multiple peer switches that each manage several APs might be appropriate.

Single WCS Deployment

When you deploy a D-Link Access Point, the D-Link WLAN Controller Switch can automatically detect the AP and assign a default profile, which includes automatic RF channel
