About WDS
WDS Device
Integrated Access Device provides the WDS functionality using an independent WDS Device
that sits between the Bridge and the Wireless Device and performs the following functions:
• Dynamically adding and removing WDS links with other APs.
• Adding/removing WDS remote AP’s MAC address from data packets.
A WDS device has several wds_x ports and one wds_local port. For each WDS link, bridge
opens a channel on a wds_x port and attaches the MAC address of the remote AP (in some
other BSS) to this wds_x port. The packets destined for any STA in the other BSS connected
by a WDS link, are exchanged with the bridge through these individual WDS ports. Bridge also
opens a channel on the filtering/filtermac compound device, which in turn opens a channel onto
the wds_local port.
WDS device uses this port for transmitting and receiving the packets belonging to its own BSS.
Typical WDS Scenario
Figure: Distribution System connecting two BSS’
In the above figure, there are two BSS’, viz., BSS-1 and BSS-2, placed in the radio range of
each other. Laptops and PCs with wireless stations are associated to the Access Points (APs)
controlling their respective BSS’. Using WDS feature, both the APs are connected to each other
‘wirelessly’.
Now, if a PC or a laptop (say PC-1) in the BSS-1 wants to send some data to a PC (say PC-2) in
the BSS-2, then this data transfer will take place using WDS feature between the two APs.
Integrated Access Device AP allows WDS links towards multiple (up to four) APs. In Integrated
Access Device, the WDS link operates on the same frequency channel as used by the
associated wireless clients.
