In 2016, G.fast looked very promising.
Thousands worked at developing and deploying.
It wasn't enough.
Most carriers are investing
in fiber or 5G instead.

536 Mbps and upload 116 Mbps. Telekom Austria has linked up a company offering working and event space via G.fast, the first actual customer connected. TA doesn't expect volume deployments until 2016, however. They see G.fast as an alternative to fiber for 400,000 apartments in Vienna alone. Many are older buildings where people are resistant to drilling for fiber. The French report a similar resistance to drilling.
The press release only stated, "Data rates of several hundred Mbit / s." The 536 megabit figure was confirmed to reporters at a press conference with the screenshot of the screen test and reporters in the German press. There are numerous challenges that might drive the speed down in deployment but also room for the chip designers to improve things. Alcatel supplied the equipment, using Sckipio chips. Sckipio's modem chip isn't available yet so they used a four port chip designed for the other end of the system. Sckipio expects gateway chips within six months.
Thanks to Mathew Pitt-Bailey for getting me the more accurate data.
World's First Ultra-broadband customer with G.fast in the network of A1
- The need for ultra-fast broadband services with data rates beyond 100 Mbit / s is increasing especially in urban areas more rapidly, as a powerful fiber infrastructure can be completed nationwide. A1 shows together with technology partner Alcatel-Lucent G.fast, a copper-based cable Ultra-wideband technology for areas with mainly multi-storey, existing buildings.
Data rates of several hundred Mbit / s on existing copper lines
"We have succeeded in connecting the world's first customer with G.fast to our network, with a very promising technology for us. We are in urban areas will soon be able to offer ten to twenty times as high data rates over copper lines as in the past, "says Hannes Ametsreiter, CEO of A1 and Telekom Austria Group." Fiber to lay each apartment up in the long-term vision of A1 remains. However, until we reach a similar distribution as currently in fiberglass with copper, G.fast is a smart transitional technology. "
G.fast allows ultra-broadband services with data rates of several hundred Mbit / s over existing copper network. Since the length of the copper lines, it may be only a maximum of 250 m, this technology is particularly suitable for multi-storey buildings in cities. On short distances copper lines are very powerful, but at high data rates tend to interfere with each other. These disorders are largely eliminated with vectoring, ie by calculating a compensation signal. Since it G.fast comes to very high data rates, a tremendous computing power is necessary for this.
Reduction of costs allows more rapid expansion with Ultra-High
"The supply of G.fast requires considerably less effort than the rewiring of a building with glass fiber. We carry the fiber optic cables from the A1 network to the basement of a house. From there, the existing copper cables are used. The achievable data rates with G.fast will be for at least the next ten to 20 years for the most demanding households more than enough. If in this period, pending a reorganization of the staircase, the household may choose a convenient time to yourself to let lay fiber to the homes without having to give up then to ultra-broadband services, "said Marcus Cruel, A1 CTO.
Thomas Arnoldner, CEO of Alcatel-Lucent in Austria, adds: "We are proud that our strong partnership with A1 helps to accomplish quantum leaps in broadband innovation. Ultra-broadband, IP networking and cloud are the focus of Alcatel-Lucent and its world-renowned research arm Bell Labs. This connection of the first live customers with G.fast we demonstrate together with A1, the suitability of a technology that significantly accelerates the availability of Ultra-High. "
Alone in Vienna potential for approximately 400,000 households
The trend towards higher data rates is explained by the demand for high definition television, video-on-demand and complex services on the Internet. New buildings are already connected with future-proof fiber optic lines, but additional cabling in buildings is often only part of a comprehensive redevelopment useful. According to the first analysis of A1 are in Vienna alone 30,000 buildings with more than 400,000 households for the resource-configuration with G.fast.
Wide availability from 2016
G.fast located at A1 currently still in the testing phase, with commercial availability is expected in 2016. The preparations for Ultra-Broadband Services at A1 still run at full speed in order to ensure the fastest possible availability of fiber-optic lines to the buildings can.
