PLC (power line communication) extenders are devices that allow you to extend your home network over the existing electrical wiring in your home. They work by transmitting data over the power lines in your home, allowing you to connect devices to your network in areas where it would be difficult or impossible to run Ethernet cables. PLC extenders can be particularly useful in large homes or buildings with multiple floors, where it can be difficult to get a strong wireless signal in every room. PLC extenders are also a convenient and cost-effective way to add network connectivity to devices that don’t have built-in Ethernet ports, such as smart TVs, game consoles, and security cameras.
