DS2, a Spanish powerline chip maker, announced today it has developed a new technology that will double the peak data rate of today’s broadband over powerline equipment and networks to 400Mbps. The company expects the chip to be used in products targeting very high bandwidth home networking applications including multi-room HD-IPTV delivery and networked PVRs.

This leap in performance is slated to hit the market sometime in 2009, but DS2 will demonstrate the technology in New York next month. The company also said the 400Mbps system would be compatible with its previous 200Mbps version, which has already been tested and deployed by leading operators such as British Telecom, Telefonica, and Telecom Italia, and vendors of networking products including D-Link and Netgear.
