Open KimonoCompanies time releases for BBWF, the biggest event of the year. Here are some possibilities for the companies that haven't provided me news yet.

Huawei will brief me at their Hangzhou event this week. For now, I know the 96 port external vectoring boxes are doing well in customer labs and probably ready. Two telcos were impressed.

(Huawei, Calix, and Adtran are very generous with the press, hosting regular events. All three do a good job trying to answer questions when they can. The result is they get far more coverage. I make a point of reaching out to those who tell me less, including writing this as a reminder.) 

Metanoia is the third G.fast chipmaker that joins the UNH interops.

Swisscom is using their chips, which implies Huawei. I hope to learn more about them at the interop demonstration at the show.

Nokia is the longtime DSL leader and the originator of what has become G.mgfast at speeds up to 10 gigabits.

Their product and engineering people are open and forthright. Several are speaking at BBWF and the Broadband Forum events and I'll learn a great deal from them. Unfortunately, their pr people are gracious but rarely go beyond press releases. Back in Lucent days, they thought a reporter's job was to promote company press releases. I'd report more about Nokia if company policy changed and pr could do more.

Broadcom is the most closed company in telecom. Their pr people are courteous and professional, but limited by company policy. I nearly always know what's coming because they have to tell their customers, who tell me. Everyone in the industry discovered in Henry Nicholas days that Broadcom believed in sharing as little information as practical. He believed business is war and in "Art of War" style stealth.

Clamming up may not be the wrong policy. Broadcom has done very well, obviously, without press or advertising. Their products are often outstanding.  That's continued under the new owner. Apple and Google are also secretive and have done well.
Please email me if you can give me more information.

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
