D-Links Power Line Homeplug AV Wireless N Starter Kit uses standard electrical wiring to connect multiple devices, by creating a wireless network or extending the existing one, in areas of your home where the signal from your main router may not be strong enough. You can connect any device such as computers, routers, media players, gaming consoles or storage devices at speeds of up to 300 Mbps wirelessly & 200 Mbps over electrical wires, making this medium ideal for streaming high quality HDTV signals & enjoying music & games anywhere in your house. Advanced technology built into these adapters makes it more resistant to electrical interference from other household appliances, so you 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. In addition, the adapters in the DHP-W307AV kit are designed with power-saving features, such as st&-by mode & WLAN Scheduler, which shuts down the wireless when not in use, for example during working hours or at nights.
