Dark Green: Firm commitments from incumbent: BT (10M), Belgacom, Australian NBN, Swisscom,  Austria, Bezeq Israel, Chunghwa Taiwan, Telus Canada, Telekom South Africa, SK Korea, (U.S.) AT&T, Century, Frontier, Windstream, Belgium, Omantel

Mid Pink: Smaller carriers in Germany, Norway, Finland, Japan

Light Green: Incumbent likely:  France, Germany, Italy

Of the 15 most important people bringing G.fast to production, all but 3 or 4 will be represented at the G.fast Summit, May 19-21 in Paris. Most of the people who pointed the way to hundreds of megabits on DSL will be there. From the committee that created the standard, Tom Starr of AT&T and Kevin Foster of BT open on Tuesday. Les Brown and Frank van den Putten follow. 

The carriers furthest along follow: Trevor Linney of BT, Gerald Clerkx of Telekom Austria, Marcel Reitmann of Swisscom, Hubert Mariotte of FT/Orange and Hyung Jin Park of KT. Top chip engineers Debu Pal and Rami Verbin are on board.

As a member of the advisory board, I know how carefully Remi thought about who would be valuable and what the most important topics will be. Lots of questions back and forth, which I welcomed because it meant a very strong event for me. In three days last year at last year's G.fast Summit, I learned almost everything about to happen afterwards. I also learned that some claims were hot air.

A huge difference between the Upperside Events and too many others are that it is not "pay to play." Yes he does want sponsorships, but many of the speakers are from corporations that don't buy sponsorships. So he doesn't have to offer spaces to anyone who isn't respected by the experts.

I had that freedom choosing speakers when I did three Fast Net Futures conferences with Jeff Pulver and the VON organization. I invited the best and they covered topics still important a decade later. The 100 or so attendees in 2005 learned gigabits were coming years before many people believed it was possible. John Chapman, one keynote, went on to lead DOCSIS 3.1, now ready to go into production at gigabit speeds. John Cioffi, a second keynote, introduced vectoring at the event, a crucial part of G.fast.

Too many events only allow sponsors to speak, resulting in too many marketing pitches and boring canned messages. Speakers paying $70K for a 25 minute keynote - an actual price from a very big fall event - they believe they've bought the attention of the audience and often abuse it.

A shoutout to the committee who advised Remi this time:

I’m still working through remarkable presentations from the Broadband Forum events. Michael Weissman, Bernd Hesse and team did a remarkable job choosing the speakers. http://bit.ly/BBFBASE

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
