D-Links Power Line Homeplug AV Passthrough Starter Kit consists of two adapters that use standard electrical wiring to create or extend a network. You can connect any device such as computers, routers, media players, gaming consoles or storage devices at speeds of up to 200 Mbps over electrical wires, making this medium ideal for streaming high quality HDTV signals & enjoying music & games anywhere in your house. Each adapter has an electrical socket built in, so you dont need to worry about running out of sockets! Advanced technology built into these adapters makes them more resistant to electrical interference from other household appliances, so users can fully benefit from the maximum transmission speeds. The adapters also include Quality of Service (Qo S) mechanisms to ensure a lag-free experience for delay-sensitive applications such as gaming or Internet TV. All that is required for set-up is pushing a button on the side of the device. This also ensures secure transmissions between Power Line adapters. In addition, these adapters are among the first in their category to comply with the European Union directive for office & domestic devices (Eu P): when idle, they enter a standby mode that requires less than 1 Watt.
