A Wi-Fi bridge is essentially a receiver for a Wi-Fi signal (i.e. connection) originating from a Wi-Fi hotspot (i.e Wi-Fi router) that it splits (or shares) with a number of units (e.g. desktops, printers) to which it is wired by ethernet cables.

The Wi-Fi bridge itself is connected to the hotspot by a wireless signal and not by an ethernet cable. So the word "bridge" in its name means that it serves as a "link" between two or more networks within which individual components are wired together by ethernet cables.

An important consideration is that the use of a Wi-Fi bridge makes it possible to share a single MAC address among a number of clients (e.g. individual computers, printers) for connecting to one IP (i.e. internet provider)
