From the Devolo website:
Powerline technology provides internet connection without WiFi to any room in the house - this set also provides WiFi from one unit: The Internet is transmitted to any room through ceilings and walls over the electrical wiring. Any power socket is turned into a high-performance access point with the powerline adapters. Surf and stream with your connected devices at high speed in any room in your home – Powerline technology does the trick. One power socket adapter is plenty for going online with the entire multi-media centre in your living room, for example. Should minimise signal disruption.
