The author, a developer in London, successfully achieved gigabit Ethernet over their existing British phone wires using a device from a German manufacturer, Gigacopper. The device uses the G.hn standard and can operate over two or four wires, making it suitable for use with phone lines. The author notes that this technology has the potential to provide fast and reliable internet connectivity in homes without the need for new wiring. The device was able to deliver speeds of up to 940 Mbps, despite the complexities of the phone wiring in the author's home.
