World-First VDSL2 Demo Gets 500Mbps Data Transfers 110
pnorth writes "Ericsson has achieved data transfer rates of more than 500Mbps in what it said is the world's first live demonstration of a new VDSL2-based technology. The demonstration achieved data rates of more than 0.5 Gbps over twisted copper pairs using 'vectorized' VDSL2. Vectoring decouples the lines in a cable (from an interference point of view), substantially improving power management, and reduces noise originating from the other copper pairs in the same cable bundle."
