Wireless Distribuon System (WDS)
IMPORTANT: Deploy ONLY mulple TEW-821DAPs in a single DS (distribuon system).
WDS may not work with other products due to its non-standard nature.
WDS stands for Wireless Distribuon System, a non-standard extension to the IEEE
802.11 standard to allow transparent Ethernet bridging on the staon and to implement
seamingless hand-over for wireless clients roaming between dierent access points.
WDS links create transparent bridges facilitate layer 2 seamless communicaon. You
don’t have to use WDS if you don’t need layer 2 services passing through TEW-821DAP,
such as MAC ltering, and 802.1X authencaon. You can simply use AP, Client Bridge,
and Repeater mode to t most of your network plan.
The 802.11 standard only uses three MAC addresses for frames transmied between the
Access Point and the Staon. Frames transmied from the staon to the AP don’t include
the Ethernet source MAC address of the requesng host and response frames are missing
the desnaon Ethernet MAC to address the target host behind the client bridge.
WDS AP and WDS Staon uses the 4 MAC address including complete source, desnaon,
WDS AP, and WDS Staon addresses. Data frame arriving WDS AP or WDS Staon will be
translated back to 802.3 data frame with real source address instead of WDS AP or WDS
Staon address. The 4 addresses design keeps the original data frame intact bridging to
the other side transparently.
You have to use mulple TEW-821DAPs to build WDS AP - WDS Staon pair or WDS
bridge mesh groups. Dierent model with same or dierent brand name may NOT work
together because of the dierent WDS implementaon details.
WDS Bridge
In this mode, the selected interface wirelessly communicate to other WDS bridges
to make a wireless backbone. You can make a simple mesh network with these WDS
bridges. To build a WDS link, you have to list the neighbor’s BSSID (the MAC address)
as next hop packet forwarding. Your neig, vice versa, has to list your BSSID (the MAC
Address) as its next hop. Make sure all access points are congured with the same SSID as
a single DS (distribuon system), wireless channel and wireless encrypon sengs have
to be the same as well.
