A1-Speedtest 280536 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.

World's First Ultra-broadband customer with G.fast in the network of A1

Vienna, 15 October 2014
  • 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.

Deutsche Telecom: 35b Supervectoring Delayed to 2019 http://bit.ly/35blater
Broadcom is now over 3 years late. DT briefed German reporters after their financial call and revealed 35b was now delayed until 2019. 35b should deliver 200+ meg downloads 500-600 meters, a crucial tool for DT, which is losing share to cable. Cable now covers about 70% of Germany and is expanding. DT now only offers 50-100 megabit DSL while cable is often 400 megabits, going to a gigabit. 

The problem is software; the hardware is shipping and supposedly will work. DT says 35b is not ready to turn on. Broadcom in 2015 said 35b was in "production" in the press release below. Alcatel in early 2016 said to expect complete systems very soon. "35g is very similar to 17a so there should be little delay."

Broadcom's problems are leading major telcos and vendors to have a plan B, using Sckipio G.fast. DT itself is planning extensive G.fast deployments in 2019, mostly in apartment buildings. http://bit.ly/35blater

Gigabit 100 Meters - Unless the Wires are Lousy http://bit.ly/gflousy
Speeds are fine, "Unless there's a line problem." I've been reporting for three years that ~10% of lines have problems. In the chart by Rami Verbin of Sckipio, he finds G.fast goes ~130 meters on good lines. Poor lines have about half the reach. 

His chart roughly matches the reports from Swisscom, Belgacom, and England for both G.fast & vectored DSL. The 10% with problems can cause the majority of the line-related complaints to support. The angry customers drive up cost.

Rami's solution to reach the gigabit is bonding, supported on the Sckipio chips. Verbin made some additional points:

  • 4 gigabits is possible by bonding two decent 2 gigabit lines.
  • Even in a service from remote cabinets, ~25% are close enough to get a full gigabit."
  • cDTA and iDTA are practical ways to deliver much higher upstream by switching some bandwidth from downstream to upstream only when needed.
  • 35B will probably be similar but Deutsche Telecom doesn't expect to deploy until 2019. http://bit.ly/gflousy

AT&T Wants Coax 2-5 Gigabit G.fast. Very Soon. http://bit.ly/ATTCoax
AT&T faces intense competition from cable, talking about 10 gigabits in both directions. (Cable will only be 1 gig down, ~100 meg up, until ~2021.) AT&T wants something to brag about as well.

AT&T gained millions of lines of coax as part of the DirecTV deal. Alcatel and Huawei are leading the development of G.mgfast. That uses 424 MHz, full duplex, to achieve ~2.5 gigabits in both directions. The reach on telco twisted pair is only about 30 meters. On coax, those speeds can probably extend far enough to service most apartment buildings. Using 848 MHz, speeds can reach 5 gigabits. The ITU standards group has been aiming for 2019-2020 for G.mgfast, too slow for AT&T's marketers. David Titus wants a high-speed standard for coax "early in 2018." He believes that is "doable."http://bit.ly/ATTCoax
