The technology supports 1Gbps speeds. The headline has been changed to: Broadband boost: G.fast testing lab, consortium to foster 1G over copper.
The third paragraph has been changed in the story on the wire and now reads:
G.fast refers to the emerging ITU standards for digital subscriber line technology that would support up to 1Gbps speeds for local copper loops shorter than 820 feet, giving service providers a potentially cheaper alternative to fiber for connecting into businesses and homes that are consuming and creating ever more bandwidth-greedy content. G.fast, which could be ratified as a standard by year-end, would blow by VDSL2 technology, which handles speeds of up to a few hundred Mbps, albeit on longer loops than G.fast will support.
