Getting More than 400 Mbps Transmission Throughput on Home Electrical Powerlines

Home media devices continue to require increases in usable bandwidth and powerline data transmission technology has evolved to provide more available transmission bandwidth. Joseph Spisak from Sigma Designs demonstrated to me during the CES show the transmission of over 400 Mbps on powerlines using the G.HN.MIMO technology. He explained that powerline data transmission can benefit from similar MIMO technology that is used in WiFi systems. By combining multiple transmission paths between power conductors and the ground wire, powerline data transmission can become more reliable and have much higher capacity. This provides a much higher data transmission rate while also increasing the quality and reliability of the transmitted signal.
