20.1.2 Using WDS To Extend Network Beyond The Wired
Coverage Area
An ESS can extend the reach of the network into areas where cabling would be dif-
ficult, costly, or inefficient.
For example, suppose you have an access point which is connected to the network
by Ethernet and serving multiple client stations in one area (“East Wing” in our
example), but cannot reach others which are out of range. Suppose also that it is too
difficult or too costly to wire the distant area with Ethernet cabling. You can solve
this problem by placing a second access point closer to the second group of stations
(“Poolside” in our example in Figure 20.2 on page 201) and bridge the two APs with
a WDS link. This extends your network wirelessly by providing an extra hop to get
to distant stations (see Figure 20.2 on page 201).
