WDS

When two rooms, two buildings, or two ends of a yard need to be connected without pulling cable, and the remote side has cameras, industrial devices, printers, or a switch, the requirement is often called wireless bridging. It looks similar to “make Wi-Fi usable farther away,” but it solves a different problem.

Bridging is not mainly about adding another wireless entry point. It is about connecting two Layer-2 networks over a wireless link so remote devices can behave as if they are still on the same LAN.
