alphadogg writes "The ITU has taken a big step in the standardization of G.fast, a broadband technology capable of achieving download speeds of up to 1Gbps over copper telephone wire. The death of copper and the ascent of fiber has long been discussed. However, the cost of rolling out fiber is still too high for many operators that instead want to upgrade their existing copper networks. So there is still a need for technologies that can complement fiber, including VDSL2 and G.fast. Higher speeds are needed for applications such as 4K streaming, IPTV, cloud-based storage, and communication via HD video, ITU said."
Meanwhile, I'm hoping Google Fiber, FIOS, and other fast optical options scare more ISPs into action along both price and speed axes.Read Replies (0)

Hugh Pickens DOT Com writes "Suzanne Goldenberg writes at The Guardian that researchers at the University of Toronto's department of chemistry have identified a newly discovered greenhouse gas, perfluorotributylamine (PFTBA), in use by the electrical industry since the mid-20th century, that is 7,000 times more powerful than carbon dioxide at warming the Earth. 'We claim that PFTBA has the highest radiative efficiency of any molecule detected in the atmosphere to date,' says Angela Hong. Concentrations of PFTBA in the atmosphere are low – 0.18 parts per trillion in the Toronto area – compared to 400 parts per million for carbon dioxide but PFTBA is long-lived. There are no known processes that would destroy or remove PFTBA in the lower atmosphere so it has a very long lifetime, possibly hundreds of years, and is destroyed in the upper atmosphere. 'It is so much less than carbon dioxide, but the important thing is on a per molecule basis, it is very very effective in interacting with heat from the Earth.' PFTBA has been in use since the mid-20th century for various applications in electrical equipment, such as transistors and capacitors. 'PFTBA is just one example of an industrial chemical that is produced but there are no policies that control its production, use or emission,' says Hong. 'It is not being regulated by any type of climate policy.'"Read Replies (0)
