G.fast DSL standard to speed up broadband over short distances2014-12-08 10:56 by Daniela

The International Telecommunications Union (ITU) has approved G.fast, the new broadband standard designed to deliver access speeds of up to 1Gbit/s over existing telephone lines.
G.fast is much cheaper to install than fibre to the home (FTTH), and the ITU believes that customers will be able to install it themselves. However, it is not as fast as FTTP and the speed falls off very fast with distance. The union claims that the technology achieves speeds at up to 1Gbps at distances of up to 100 meters. For further distance, the speeds decreases to about 150Mbps over 250 meters.
"G.fast will increase the feasibility of implementing bandwidth-intensive services such as Ultra-HD '4K' or '8K' streaming and next-generation IPTV, advanced cloud-based storage, and communication via HD video. The standard will comfortably serve the broadband access needs of small-to-medium enterprises, with other envisioned applications including backhaul for small wireless cell sites and Wi-Fi hotspots," the ITU said in a statement.
The new standard is expected to complement the fibre to the home (FTTH) technologies in scenarios where G.fast is a more cost-efficient strategy. First certified G.fast implementations are expected to appear on the market before the end of 2015.
