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

CerberusCerberus offering it to customers. BT fell a little behind schedule but will cover several hundred thousand homes with this fall. 10 million are promised by 2020. The retail ISPs are now active, with Cerberus offering the service on its web site.

"Up to 330 down, 30 up" costs 90 pounds including VAT, $117. "Up to 160 down" costs a little less. BT's fiber home is actually a bit cheaper.

Cerberus reports, "BT will only allow an order to be placed where the availability checker states that the predicted speed is 80.01Mbps or higher." The reach is estimated at ~300 meters.

BT has done extensive tests on their lines and can predict actual speeds fairly well. BT's early testing found 99%+ received 100 megabits or better.

A BT engineer will do the install, with plans for customer self-install in the future. Swisscom is already doing customer self-installs. Early days, 20% have required an engineer to follow-up. They are working on reducing the number of truck rolls required.

Great to see things are finally happening.

Cerberus launches ultrafast 330Mbps FTTP and trial G.Fast broadband services

Cerberus is proud to announce its new range of next generation broadband services, delivering speeds of up to 330Mbps, at break-through affordable prices. The new range of Internet services are ideal for businesses needing ultrafast connectivity downstream and upstream, with short lead times, flexible contracts and low prices.

Cerberus FTTP services provide real-world connectivity at speeds of up to 330Mbps downstream and 30Mbps upstream over BT optical fibre all the way to the premises, requiring no separate telephone line, and delivering rock-solid performance free from interference, regardless of line length.

Cerberus G.Fast services use BT Openreach's new G.Fast technology, an enhancement to FTTC. These services run over a standard BT phone line and offer speeds up to 330Mbps, depending on line length and quality. Currently in advanced stage trial, these services are subject to limited availability, but if you are in a trial area, you can order online right now and get the benefit of this next-generation technology, months before general roll-out.

With introductory prices for 330Mbps FTTP at just £67.50 + VAT per month and 220Mbps for £55.00 + VAT per month, Cerberus is making ultrafast business connectivity available to any business, large or small at industry-leading, affordable prices. FTTP and G.Fast have lead times of just 10-15 days versus months for leased lines, and come with a choice of 12 or 24 month contracts to suit your requirements.

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.

Deutsche Telecom: 35b Supervectoring Delayed to 2019
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 DT itself is planning extensive deployments in 2019, mostly in apartment buildings.

Gigabit 100 Meters - Unless the Wires are Lousy
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 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 & 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.

AT&T Wants Coax 2-5 Gigabit Very Soon.
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."
