Using WDS to extend coverage in an area that does not have
Ethernet infrastructure
There are situations in which WLAN coverage is required in a warehouse, parking-lot, or similar area
that does not have any Ethernet infrastructure but has access to an AC supply. For such applications,
WDS can be used in combination with DC power bricks to efficiently provide WLAN coverage.
The deployment of the WDS APs should be performed in layers, starting with APs that can connect to
the wireless infrastructure via a single WDS hop, continuing with those requiring two WDS hops and so
on. Only consider using two or more hops if the coverage gap cannot be filled with APs that are only
one WDS hop away from the wired infrastructure. For each layer:
1 Identify the position of the child APs so as to maximize coverage while taking into consideration the
availability of a parent (see below).
2 Identify the preferred and back-up parents for every child AP. Take into consideration the following
factors:
The parents must be enough close to their children so as to guarantee max PHY rate.
●
It is better if every child has a different parent in order to distribute load evenly.
●
3 Identify the channels to be used by every WDS link. Investigate alternatives to avoid overloading a
single channel:
Keep neighboring WDS trees on different (non-overlapping) channels.
●
If you are using more than one WDS hop, try switching between radios every hop.
