WDS Frequent Asked Quesons
What is WDS?
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.
Should I use WDS or not?
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-753DAP, 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.
What problem WDS is resolving?
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.
What should I have to build WDS network?
You have to use mulple TEW-753DAPs 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.
