BT G.fast-box2,000 homes connecting in coming weeks. Everyone in the industry is watching BT's trial of G.fast - even if BT is now deploying "G.halffast." Gavin Patterson. CEO of BT is telling investors and regulators BT will rapidly deploy 10M+ lines. In 2014, BT tested G.fast technology at 600 and even 700 megabits down on very short loops. This February, Patterson was still talking 500 megabits. Those speeds required going to many of Britain's 4,000,000 "distribution points."

This spring, they reduced the targeted speeds to 250 correction 10/10 330 megabits, going to existing street cabinets instead of the distribution points. The money men decided the higher speeds weren't worth the extra cost. That's risky - cable in England will soon be at a gigabit. Many BT customers - 5-20% - will get much slower speeds, depending on how many cabinets they ultimately deploy.

Optimists - including the chip vendors - think tens of thousands of lines will ship worldwide soon and mass production begin early next year. Others - including sensible people at BT - don't want to commit until they have the results from thousands of lines in the field. 

AT&T plans similar, as do some of the smaller Europeans.

Thanks to Guy Daniels of TelecomTV for the picture and catching the speed limit in the press release. I had missed it.

BT Better BroadbandHere's the release.

First customers connected in trial of G.fast ultrafast broadband

Press Release  •  Aug 25, 2015 00:02 BST

 

Residents of Huntingdon – a market town in Cambridgeshire – today became the first people in the UK to take part in the field trial of a new type of ultrafast broadband technology from BT.

The trial, which is being delivered by Openreach, is open to all communications providers on equal terms. That means people will have a choice of service provider and any technological developments will benefit the wider industry.

Two thousand homes and businesses will be covered by the trial in the coming weeks. It is already delivering speeds of up to 330 megabits per second (Mbps) - more than ten times the current UK average - using G.fast, a new technology that has been pioneered by BT's R&D division.

G.fast changes the way today’s broadband is transmitted, delivering ultrafast speeds that currently require fibre to be run all the way to the premises (FTTP). This is significant as it will enable Openreach to make ultrafast broadband available to a much larger number of homes and businesses, and in a shorter timeframe, than if it had focused on FTTP alone.

If trials* like the one in Huntingdon prove successful - and if UK regulation continues to encourage investment - Openreach aims to start deploying G.fast in 2016/17 alongside its fibre-to-the-cabinet and fibre-to-the-premises services.

The company believes that G.fast will enable it to make speeds of a few hundred megabits per second available to millions of homes by 2020 and deliver up to 500Mbps to most of the UK within a decade as the technology is developed further.

Culture Secretary John Whittingdale said: "The UK already leads Europe when it comes to superfast broadband coverage and speeds, with around 40,000 more homes and businesses getting access every week thanks to the government rollout.

"We want to stay ahead of the competition and so it’s good to see this continued investment and innovation in the industry. BT is harnessing its world-class technology and engineering expertise to help the UK lead the way on ultrafast broadband and remain a world leading digital economy."

Joe Garner, CEO Openreach said: “Today is the start of a new chapter in building Britain’s connected future. This is the largest trial of G.fast technology in the world and it builds on the pioneering research of BT’s world-class R&D teams.

“We conducted the world’s first G.fast trial in 2013, and our experts have been heavily involved in creating global industry standards for this technology. We're now eager to support all our service providers in learning how customers enjoy the service.
“The people of Huntingdon will play an extremely important role in helping us gauge how the technology performs, and how we might deliver ultrafast speeds to more of the UK over the coming years.”

The trial will run for 6-9 months, allowing Openreach, and its 8 communications provider trialists, as well as BT’s R&D division, to assess the technical performance of the technology across a large footprint.

Various methods of deployment will be used to provide a valuable insight into how the technology can be used on a day-to-day basis, including how usage might grow over time.

The speeds on offer will allow people to stream live ultra-high-definition 4K video content to multiple devices at once, all whilst simultaneously browsing the web, uploading videos and photos, or playing online games.

The company has pioneered research into G.fast technology since 2007 and has been heavily involved in driving the creation of global industry standards in that time. It is working on the trials with international vendors ADTRAN, Alcatel-Lucent andHuawei, and also with chipset manufacturers and global standards bodies, to drive the speed and performance of G.fast technology.

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
