What Does Power Line Ethernet Bridge Mean?
A power line Ethernet bridge is a device that is used to extend a local area network into other rooms within a house or building using the existing electrical grid within the building. A bridge plugged into an AC outlet is connected to the router using a network cable and, in a separate room, another bridge plugs into the outlet to provide an Ethernet port for another computer or router.
Techopedia Explains Power Line Ethernet Bridge
A power line Ethernet bridges serve to “bridge” the Ethernet standard with the power line to allow data to travel through already existing power lines within a building. This saves money and effort that would otherwise be put into running additional wiring in order to extend a network and allows one to quickly set up an extended network simply by plugging these devices into an AC outlet. These bridges are usually small rectangular devices that are just slightly bigger than standard wall chargers.
