2. TYPES OF NETWORK CONNECTIONS > Powerline Networks

Powerline Networks

In a powerline network, computer data moves through a building's existing electric wiring. Each computer connects through a parallel port, a USB port, or an Ethernet port to a data adapter that plugs directly into an AC wall outlet. The same power transformer that feeds your house wiring also isolates your data network from your neighbors.

The most widely used standard for powerline networks is called HomePlug. The greatest advantage of HomePlug and other powerline networks is that the wires are already in place. Every AC wall socket in the house can double as a network connection point. It's also more secure than Wi-Fi, and it can reach greater distances than a Wi-Fi network with just one base station. Wi-Fi signals are often blocked by thick walls and other obstacles that make no difference to a powerline system.
