Example 2: Roaming with WDS Access Points
Figure 54
WDS Roaming
Another common use for WDS is extending the range across a large wireless network but allowing roaming
connections between access points or being able to switch to the next access point when out of range of
the previous access point. Figure 54 shows a bridging network with a number of access points all with the
same SSID, and network structure, so the Stations can freely roam between access points.
Each access point then needs a separate connection to the next access point, which is provided using the
WDS virtual access points or stations. Site B is acting as a virtual access point for Site A and C, which in turn
are acting as virtual Stations. This setup can be replicated to extend the range and will allow any roaming
stations full connectivity across a network

Example 3: Adding Redundancy
In the example below, 4 x access points (A, B, C, and D) form a mesh network using only WDS bridge
interfaces. Each of the access points may also have its own associated clients. Each access point is
configured with a different SSID, which means that the clients associated with each access point are fixed.
