With a powerline adapter, you can turn any outlet in your house into a network connection or WiFi hotspot. You can do that without pulling cables. With a set of 3 powerline adapters, you can create a network connection or hotspot in 2 locations. This way, you provide WiFi or a network connection in extra rooms or multiple floors. For example, you can go online in your home office or provide a network connection in your game room. Because the internet goes via the AC power, you don't have to pull cables thanks to the powerline adapter.
