The DHP-343 PowerLine 4-Port HD Starter Kit gives you everything you need to connect computers, digital media players, game consoles and other Ethernet-enabled devices in a network via your home's existing electrical wiring. Simply plug in both the one-port adapter and the switch to power outlets in your house and you're ready to connect your Ethernet-enabled devices.
D-Link's Powerline HD Starter Kit delivers up to 200Mbps over the pre-existing electrical wiring in a building. This fast transmission speed provides ample bandwidth suitable for streaming high-quality video HDTV signals, while simultaneously providing high-speed Internet access throughout an entire home. Using Quality of Service (QoS) technology, this adapter is able to ensure that low-priority traffic does not interfere with bandwidth-sensitive applications such as VoIP phone calls and online games.
