6 Creating WDS links
Key concepts
The Wireless Distribution System (WDS) feature enables you to create point-to-point wireless
links between one or more M210s. These links create a wireless bridge that interconnects the
networks connected to the Ethernet port on each M210. For example, in the following figure,
M210 #2 and M210 #3 use the WDS to create a wireless link between the main office network
and a small network in a warehouse:
WDS links provide an effective solution for extending network coverage in situations where it is
impractical or expensive to run cabling. Each M210 can create up to four WDS links.
Note A network that includes WDS links should be distinguished from a group of clustered APs.
WDS enables wirelessly extending the network, whereas clustering is used to simplify AP
administration and optimize bandwidth use. See Clustering multiple M210s on page 81 for
more information.
Simultaneous AP and WDS support
The M210 simultaneously supports wireless communities and one or more WDS links. Although
this offers flexibility, note that the total available bandwidth on the radio is shared between all
WDS links and wireless users. This can result in reduced throughput if high volumes of traffic
are being sent by both wireless users and the WDS links.
