G.fast,

  • 500 megabit G.fast to 15M Brits

    G.Fast performance per AlcatelG.Fast speeds. Larger version below  Update 7/13 I've since learned the BT target speed is 250 megabits because they don't intend to deploy enough fiber for higher speeds. From January: If a 4,000 home summer trial goes well, 3/4ths of the country will covered over a decade.  Gavin Patterson's plan goes far beyond anything even rumored in any other country. Trevor Linney and BT were among the first testing G.fast. At that time they were part of the gigabit hype. Patterson's announcement this time is far more realistic, speaking of "hundreds of megabits" for now. In fact, BT's talk of 400 metres suggests they are looking at one of the Midi-DSL versions rather than today's G.fast.

    • "speeds of a few hundred megabits per second to millions of homes and businesses by 2020. Speeds will then increase to around 500 Mbps as further industry standards are secured and new kit is developed." 

    A few hundred megabits is closer to the current state of the art, especially if you measure download speeds. It's realistic to expect improvements to G.fast over time.  The current designs only use 106 MHz but the standard allows up to 212 MHz. Alcatel and other engineers are confident that non-linear precoding will be a major improvement but non-linear wasn't ready for the current version of the standard. I believe the noise-cancellation (vectoring) in the earlier chips will have room for improvement.

    Huawei supplied the gear for the earlier BT testing, Their HiSilicon subsidiary is working on a G.fast chip but I don't know if it's ready. If HiSilicon isn't available, both Sckipio and Broadcom are promising chips for trials in the summer. 

  • AT&T chooses 400-700 meg G.fast for ~5M FTTP homes

    Not a gigabit but pretty darn good. AT&T, assured the DirecTV merger is going through, is about to go public with the long-planned upgrade of ~5M U-Verse homes to hundreds of megabits. They will take four years and reach about 15% of their homes. Gigabit gear won't be available for several years.

    Randall Stephenson in 2004 told Wall Street AT&T was using fiber, not copper, for all “new builds,” although I believe it took a few more years. “New builds” are 1-2% of the network each year. That suggests four million to eight million homes are ready with FTTB.

    With most of the construction already done, the upgrade will easily fit in AT&T reduced capital budget. I estimate G.fast will cost $75-250 per home passed. The cost over four years is is only a few % of annual capex and will be recovered in months from customer charges. It would be stupid not to upgrade and AT&T's top management isn't stupid.  

    The 400-700 megabit down speed of today's G.fast is confirmed by the early field trials. I previously reported that Swisscom, "Gets between 285 and 402 Mbps downstream and between 85 and 109 Mbps upstream. Results depend on copper cable length: on short copper cables (ca 24 meters) we were even able to reach 624 Mbps Downstream / 151 Mbps Upstream in field but without connected customers." Telekom Austria measured 536 megabits down and 116 up.

    The chart below, from Alcatel, shows combined upstream and downstream speeds in early testing. Combined, the speeds up to 150 meters are 500-800 megabits. Subtracting 100 megabits for the upstream yields 400-700 megabits downstream, what I had estimated from a different data set.

  • G.fast Paris Springtime (May 18-20, 2016) Should be the Event of the Year

    Paris-Concorde-by-Dennis-JarvisAn exceptional event returns. In 2015, BT. AT&T. Swisscom. Broadcom. Sckipio. Ikanos. Alcatel. Huawei. ASSIA. All sent a senior tech guy, often the CTO. It went beyond a great education. The future of G.fast was defined in a way you only expect in ITU standards. 

    Attendance was good but not too many for lively debate. I chaired and ensured very point of view was expressed. We focused on key questions including how to get to the gigabit speeds promised. Trevor Linney of BT made the case for long reach from cabinets rather than distribution points. The people who wrote the standard explained just what it meant.

  • More Bits, More Power, More People Connected for BT

    British-Telecom-noise-dataBT thinks the current G.fast is too conservative and the standard needs to be changed for more performance. Gavin Patterson is telling the government BT is going to deliver a gigabit. He's arguing BT shouldn't be broken up because BT is building "the best network in Europe." But his best network is running at 330 megabits while cable around the world is going to a gigabit. Comcast is about to offer a gigabit to 40 million homes. 

    The order came down from the top: make it faster. The same thing is happening at AT&T. They've promised 12M lines of "GigaPower," much of which will be G.fast. But it's not a gigabit. So AT&T is leading the move for a new standard with more speed.

    BT Openreach's latest update lists key developments they expect will increase speeds:

  • Reverse power working at Aethra

    aetheaAethra_videoDemo'd live at BBWF. Great Britain has 4,000,000 "distribution points," simple copper boxes generally without power. Bringing electricity to each box could double the cost of G.fast deployment, which is targeted at $100-250 home. Add monthly charges as well..

      To many telcos, the biggest advantage of G.fast is "parasitic power." The G.fast gear gets power from the customer gateway, not from the telco system. Instead of running a powerline to each box - often very expensive - the G.fast DSLAM draws power from each user's modem. That allows telcos to pop mini-DSLAMs on poles, in small underground spaces.... 

       The standards committee was confident parasitic power would work well. 

  • Schneider of Adtran: We bonded G.fast for over a gigabit

    Fleming007impressionGigabit required to keep up with cable. It's in the standard, but until recently everyone assumed it would be delayed for lack of customer demand. But with gigabit cable coming close, AT&T is pressing for a gigabit over DSL. Adtran, a major supplier to AT&T and Deutsche Telekom, has proven that G.fast can easily exceed a gigabit downstream by bonding two lines. It's just a lab demonstration for now without a timetable for field trials. 

    G.fast vectoring and pre-coding require serious processing power to keep up with the high speeds. Bonding for even higher speeds is a challenge, but Adtran CTO Kevin Schneider doesn't see any obstacles that will prevent practical deployment. 

  • Taiwan, Alcatel: G.fast is Commercial

    chunghwaBT calls 4,000 a trial but Alcatel calls similar at Chunghwa "first commercial deployment." Whatever you call it, G.fast is here, with about 10,000 lines about to be installed. Rami Verbin of Sckipio told me the real growth won't come until 2016 and it looks like he was on track. A couple of years ago, Chunghwa promised to spend $3B to bring "fiber" to 97% of premises by 2015. but Tony Brown reports only 200,000 true fiber to the home lines by the middle of this year. 

    The embarrassing delay gives them incentive to make stronger claims than BT. Taiwan is probably not connecting significantly more lines this year than England. Everyone knows this is early equipment likely to need debugging. The average Taiwanese will get higher speeds than the average Brit because there are far more apartments dwellers in Taiwan. The English love their gardens. From the basement, speeds will often be 400-700 megabits down. 

    Britain originally planned to bring 400-700 megabits to most homes but decided not to spend the money on the million+ field units that would require. Instead, they will run G.halffast, the same gear but over longer runs from the (much fewer) existing cabinets. The official word is that they will reach 300-500 megabits combined upstream and downstream. I'll call it 250 meg down until proven otherwise.

John Cioffi theorizes that 1 Terabit/s over 100m is possible. Several world-class engineers have confirmed the theory appears correct. The same higher-order waveguide modes could deliver 10 Gbps at 500 meters, which is exciting some of the most important companies in the industry. It could drastically reduce the cost of backhauling 5G small cells in the required millions of locations. 

Some are using the name Surface Wave over Copper (SWoC) instead of TDSL as the system moves closer to test. Building a test system and proving the real challenges can be met will be expensive. The frequencies involved are at 50 GHz and higher, 200 times higher than the new 212 MHz G.fast. http://bit.ly/2xHJCch

Who needs fiber? Backhaul By a Dozen Bonded DSLshttp://bit.ly/fiberno
12 bonded lines of 35b VDSL should be able to deliver 2 gig downstream ~400 meters. That's comparable to the most common G.fast backhaul, 2.4 gig GPON. Telcos are confident few will use the high speeds simultaneously so the high over-subscription is realistic. Upstream on the older DSLs is lower, so the upstream will probably be limited.

Kurt Raaflaub says Adtran has trial units at customers. As far as I know, this is the first public description of bonded 35b and I hadn't anticipated this possible use. Deutsche Telekom says 35b will be ready for deployment the second half of 2018. http://bit.ly/fiberno

(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.)

G.fast News - AT&T Sees 1.5 Gigabits
Eric Small of AT&T tells Sean Buckley "In generation 2, you get about 1.5 Gbps of throughput," confirming what the vendors promise. "Not that you would use more than a gig in either direction, but it gives you the flexibility to use a gig in one direction and 500 Mbps in the other direction."

He adds, "The really interesting part of the second generation of Gfast is it allows for reverse powering, which means the power could come from the individual subscribers." Fierce Telecom http://bit.ly/2yajjiW

Randall's Xmas: 144 Gigabits, 212 MHz, 96 Port, DTA From Sckipio http://bit.ly/150gig
Randall Stephenson at AT&T "needs 1 gig speeds."and promises "1 gig speeds ubiquitously."  http://bit.ly/GigForAll Sckipio is ready with 212 MHz Amendment 3 chips soon to sample to selected customers - including AT&T suppliers. Using 212 MHz of spectrum almost doubles the capacity of G.fast, reaching close to 2 gigabits between upstream and downstream in lab conditions.

96 ports at 1.5 gigabits is 144 gigabits. It should be achievable over the short loops typical in apartment buildings, although they will nearly actually all be a maximum. Adtran and Huawei have demo'd external boxes that can vector 48-96 ports, but Sckipio does not require the complexity of external vectoring. Instead, the first DSLAM supports 24 or 48 ports and can be daisy-chained with others on demand. This reduces the initial capex. cDTA allows switching between upstream and downstream for each line. Much more http://bit.ly/150gig

Lincoln Lavoie sees "cross chipset interoperability and performance at all levels including device software for management and control." Gear with chips from Broadcom, Metanoia, and Sckipio are working with each other at a good speed, usually 600 megabits or higher. EXFO and Viavi testers also passed.

He adds, "Gfast testing has already been more rigorous than any previous certification testing and we are testing individual features more deeply than we have on any previous technology."Interoperability" is considered to mean working reasonably together, not necessarily at maximum performance levels. http://bit.ly/unterop

Australia NBN Begins Million Home Fiber To The Curb http://bit.ly/nbnFTTC
Officially, it's not G.fast but they aren't stupid. When they run "fibre to your driveway," they will be within 100 meters of most people. That allows 500-800 megabits of G.fast today and over a gigabit as amendments 2 & 3 are delivered next year. Presumably, the final announcement is waiting for a government plan to deal with the over $10B in cost overruns. The good news from Australia is that finally construction is catching up, "The nbn network is currently available to almost one in two Australians, is scheduled to be three-quarters built by mid-next year and complete by 2020."

nbn is the most politically driven network in the world. Julia Gillard's election as Prime Minister in 2010 was decided by a single voter in Parliament, who attributed his decision to her support of a full fiber nbn. The Conservative government that succeeded Gillard switched much of the network to DSL, hoping to save money. The savings have proven modest; the real cost problem was not the technology choice. http://bit.ly/nbnFTTC

Calix: We Can Produce Miracles (Sometimes) http://bit.ly/Calixmir
The right (straight) cable allows remarkable choices. Bill Bittencourt startled the G.fast Summit with new results from the lab and the field. They said it couldn't be done, but Calix customers are proving it is possible to use multiple DSLAMs. Instead of being limited to 16-24 G.fast customers, that can be doubled and possibly tripled. In early testing, the second DSLAM resulted in less than a 2% loss. Many North American buildings have straight cable – otherwise known as CAT1 or “station wiring” – from a distribution point to each unit. Geoff Burke explains, "In essence, what this means is that typical MDUs have insulated wiring from the Distribution Point to the unit, which greatly minimizes cross talk and loss. VDSL2 and G.fast have minimal interference over in-building cabling. http://bit.ly/Calixmir

They gave no details of when, where, or how many, so it wasn't worth a headline. In the release is the claim they've shipped, "30 million vectoring lines." I'd be surprised to discover that even 10% of those are actually deploying vectoring. Similarly, Adtran claims 10M vectored. There are remarkably few vectored lines in service. The claimed vectored ports are probably 10x or more the number of actual vectored lines. There just aren't many homes connected with vectoring. http://bit.ly/30mvector

Metanoia Surprises With G.fast Interoperability http://bit.ly/metanoiag
Great to have another chip source. Broadband Forum/University of New Hampshire has announced the first six products to pass their testing: ARRIS, Calix, Huawei, Metanoia, Nokia and Technicolor. Nokia/Alcatel has long been #1 in DSL, with Huawei #2. Calix is coming on strong with G.fast, telling me they are adding so many new deployments they are about to have over one hundred customers in service. Technicolor and ARRIS/Pace/2Wire have long been top modem suppliers. But few in the industry know Metanoia, a Taiwanese chipmaker almost invisible when searching news, even on Google.hk. http://bit.ly/metanoiag

60+ Previously Unknown G.fast Deployments http://bit.ly/Gfast60
Especially in the U.S. and Canada, there's a stampede to reach MDU customers with five hundred megabits to a gigabit. If you want to win customers in large buildings, it's becoming a no-brainer to go to G.fast - today. About six months ago, I predicted that would be the trend, but until Calix shared their customer details, I hadn't seen evidence I was right.

There are ~30 announced G.fast deployments worldwide, so I was startled when Calix told me they have about 90 customers in active deployment. I've known the Calix people for a decade or more, and don't doubt their claim. Some undoubtedly are just a building or three, but I know others, including Century/Qwest, are far beyond that stage. Geoff Burke writes, "There is no doubt that we are seeing a major shift from promising 'pilot' technology to live commercial deployments. Calix alone has now over 90 commercial deployed customers and increasing with a dozen new customers every month. They are installing in both low-rise to high-rise MDUs, from towns to the largest cities, Business MTUs and parks and even campus environments such as universities." 74% are in the U.S., 12% in Canada, 9% in AustralAsiaPac and 5% in the rest of the world. http://bit.ly/Gfast60

Our communities are being destroyed by racial tension and we're too polite to talk about it. ... If this is a dialogue that's to begin at AT&T, I feel like it probably ought to start with me" Randall Stephenson, AT&T CEO https://youtu.be/ThO74-oFt_Q

Marcelo Claure says mobile costs are “minimal,” allowing Sprint to give away a million mobiles to poor kids. Free in France is selling 50 gigabytes+ for $22; Ambani in India is selling 10 gigabytes for $7.40. An EU estimate of mobile data cost is between 0.4 and 0.8 euro per gigabyte, which is probably high. Finnish consultant Antonios Drossos calculates the marginal cost of a gigabyte is about 0.1 euro.  See Ambani pricing isn't crazy. France, Finland, and Denmark are similar.
    David Small of Verizon estimates the cost per bit will go down 30-40% per year, confirming what I’ve written about the efficiency of carrier aggregation, advanced LTE & MIMO. That’s a drop of about ~50% in two years and ~80% in five years.Mobile speeds have gone up remarkably, putting the lie to the lobbyists’ and politician’s “spectrum crunch.” Back in 2009, the U.S. broadband planners and Glen Campbell of Merrill Lynch convinced me the fears were hogwash. Every year since has seen an increase in mobile speeds.
    The telcos need to buy much less equipment, leading to agony at Ericsson and other suppliers. The Big E has lost half its value in 18 months and is firing thousands. Verizon just fired another 3,000 while AT&T wants to chop 50,000+ jobs in the next few years. 
    Efficiency is great for consumers but many in the industry are living through nightmares.  John Donovan of AT&T says the survival of his $250B company is uncertain. 

This week’s Broadband World Forum in London will have some excitement. I have to skip the show so everyone please keep your ears open and send me the news that isn’t in press releases.

Headlines without articles yet. News is breaking faster than I can write it.

  • "F-yes for F-cell! Flying F-cell Fantastically Free of wires" Marcus Weldon of Nokia shows off the 8x8 MIMO small cell efficient enough for solar power and small enough for delivery by drone. Great picture. No delivery date.
  • EU’s new policy:  “share spectrum in all the spectrum ranges, particularly in bands below 6 GHz” The telcos will fight very hard, but “use it or share it” is the right policy for more capacity and lower prices. This is huge for spectrum policy.
  • AT&T wireless to the rooftop, below, is in Century’s Minneapolis. T plans to go after Verizon as well. Only a world-class game theoretician can predict how this will play out.
  • Comcast is building a low power wide area network with Semtech. LPWAN is remarkably cheap, which AT&T is acknowledging with an order of magnitude price drop.


Upstream 300 meg+ in 2017 at Comcast http://bit.ly/300upcab
Jorge Salinger is ready as soon as the vendors can deliver.  Casa Systems has already demonstrated 400 megabits upstream and will soon show 600 megabits. They will offer gigabits downstream only in 2016, Daniel Frankel reports, “because 3.1 was not available in upstream. ... I think it’ll be in 2017.” Comcast's $70 gigabit downstream is available today in parts of Chicago, Nashville, and Nashville with a promise to cover over 40M homes by 2018. The upstream is limited to 35 megabits, but that's about to change. 
   I had heard from cable people that they would wait for Full Duplex before upgrading speeds, so this is good news. Full Duplex - sending both upstream and down in the same spectrum - is an active project at CableLabs but likely 3-7 years from volume deployment. Comcast instead will use dedicated spectrum for upstream, possibly eight 6 MHz channels. AT&T is serious about adding 12M "gigabit" homes, using GPON and G.fast, and Comcast wants to be able to match the gigabits soon available to about 30% of the U.S.
   But when will they bring it to my house? Much more http://bit.ly/300upcab

Sprint's mobile bandwidth cost is so low they are giving poor kids 1M free lines and phones http://bit.ly/gigcost
"The new program’s cost to Sprint is minimal" Cecilia Kang quotes NYT. She added  "It doesn’t require additional network upgrades; instead, it would be the equivalent of adding more cars to a highway, the company said." That's an exaggeration, of course. Sprint may have the emptiest network in America, but some of their $3B capital budget is required for the congested areas.
    The cost of bandwidth, even on mobile, is low and getting lower rapidly. A recent EU study found fully loaded cost often one euro/gigabyte or less. Consultant Antonios Drossos emails, "the actual incremental cost of mobile data which depending on the network topology, configurations, vendor pricing etc ranges from €0.05/GB to €0.5/GB."
    Drossos is more likely on target than the EU. Free in France and several in Scandinavia are selling 50 gigabytes+ for $22.  Even if we assume people only use half their allotment, that's 80 cents retail for a profitable product. Ambani in India is selling 10 gigabytes for $7.40.
     David Small of Verizon estimates the cost per bit will go down 30-40% per year, confirming what I’ve written about the efficiency of carrier aggregation, advanced LTE & MIMO. That’s a drop of about half in two to three years and three quarters in about five years.

AT&T/DirecTV ready to go "Wireless to the Rooftop" + DSL or Ethernet bit.ly/WTTRATT
AT&T needs a tool for both coax and existing telco twisted pair. I believe they are not using G.fast at this stage, although it will be a natural choice going forward. AT&T's WTTR looks to be the same as Google's new Webpass division. Companies like Towerstream have been beaming mmWave to rooftops for commercial customers for more than a decade. Hundreds of wireless ISPs rely on mmWave backhaul as do most mobile towers around the world. The technology is old but few have done WTTR for consumers.
     AT&T has several million lines of satellite TV with roof access and wiring throughout the building, a natural for this kind of deployment. Their initial buildings are in Minneapolis. They are also planning Denver, Phoenix, and Seattle, where Century has only limited upgrades. I was surprised T is also discussing prime Verizon FiOS territory: Boston, New Jersey, New York City, Philadelphia, Phoenix, Seattle, and Washington D.C. The headline includes "Outside of Traditional Wireline Service Area."
     For $3,000, you can buy a pair of Ubiquiti radios to carry a gigabit. Siklu, which supplies Google/Webpass, and Ericsson have 5 gigabit units available with low latency. Boris Maysel of Siklu tells me they will have 10 gig in a box next year. 
     T is getting scared as gigabit cable is spreading around the country.  Ed Balcerzak expects WTTR will not just save money but will reach customers quickly. AT&T's current plan, fiber or G.fast to 12M by 2020, leaves more than two/thirds on older DSL. Cable should win most of those not soon upgraded. bit.ly/WTTRATT

AT&T, Ericsson public demo of mmWave webcast Oct 18 http://bit.ly/2egDq2u
A chance to watch.  Press releases sometimes are as credible as politician's speeches, so I'm looking forward to watching Tuesday's live demo of a 5G network. At the Texas Wireless Summit, Arunabha Ghosh of AT&T will present Designing Ultra-Dense Networks for 5G at 9:40. At 10 a.m., AT&T will demonstrate their state of the art 5G testing. This will be one of the first public demonstrations of a 5G mmWave system. Webcast by RCR Wireless.
     AT&T & Ericsson are working on phased arrays with ultra-fast beam steering, feedback-based hybrid precoding, multi-user multiple-input/multiple- output, dynamic beam tracking and beam acquisition. Beamforming and related technologies seem may be a breakthrough that extends the reach and throughput of mmWave systems. mmWave Works!, as Ted Rappaport proclaimed a few years ago. The question now is where it will prove financially practical. All those small cells and backhaul can be very expensive.

KT Giga to 9M Korea homes, Spain, Turkey http://bit.ly/KTgiga
Moving from G.hn to G.hn Wave 2 at "up to 1 gig." G.hn has grown beyond home powerline into a legitimate contender for in-building broadband. KT, using Marvell chips, has been offering hundreds of megabits since late 2014. KT reaches several million apartments now and intends to cover 95% of Koreans who can't get fiberhome by the end of 2017. That puts G.hn a year or more ahead of G.fast.
    KT, working with Ubiquoss and Lightworks, has begun exporting the system. They have a deal with Turk Telecom and a  demonstration building in Barcelona near Mobile World Congress. Chano Gomez of Marvell believes Wave 2 can match today's G.fast chips. I haven't seen test data from an independent source. http://bit.ly/KTgiga

G.fast amendments 2 & 3 for more than a gigabit http://bit.ly/2dSqtj8
Longer reach, reverse power, downloaded upgrades for the customer equipment, DTA over coax, and a dozen other improvements. At an ITU SG-15 meeting in Geneva, Amendments one and two were approved. Amendment three was consented but very few changes are likely before final approval. The major chip vendors, Broadcom and Sckipio, are already hard at work. The carriers are hoping for equipment in the second half of 2017.
     BT needs longer reach. G.fast was designed for 50-200 meters but existing cabinets are often 350 meters away or more. The new standard increases the maximum transmit power up to +8 dBm, with a practical goal of 300 megabits 300 meters. AT&T has been vocal they want a true gigabit to compete with cable, not "up to a gigabit."  http://bit.ly/2dSqtj8

24 Port DPU shipping from Sckipio, HFRhttp://bit.ly/gfast24
Until now, no one made a DPU with more than 16 ports. Curtis Frankenfeld of Century recently told me, "I would like G.fast to support a larger vectoring group than the current 16 ports." For now, Century is only using G.fast in smaller buildings. Many buildings have far more than 16 apartments, with wires in the same bundle.
   HFR of Korea has the first 24 port DPU and a giant customer ready to go. Sckipio is first with G.fast chips designed to work with VDSL 30a, the faster form of VDSL used in Japan and Korea. $15B SK Telecom is Korea's largest wireless carrier and #2 in fixed. They are targeting the 9M apartments in Korea served with VDSL and copper LAN, most running at 100 megabits. Korea Telecom is actively deploying GIGA Wire, their version of G.hn, and intends to upgrade 95% of those units by the end of 2017.  Japan is similar; millions of their "fiber" lines are fiber to the basement + VDSL.http://bit.ly/gfast24

Nokia 8 port G.fast http://bit.ly/gfastnok
The headline is the whole story. Two North American telcos have told me they need a smaller unit. They don't want to pay for 16 ports when they only need 4 or 5. Nokia has announced one. The unit is shipping. Price is undisclosed, which means the price is based on how hard you negotiate and how much Nokia wants your business. 
     I would love to add to this report that Nokia's new gear supports longer loop lengths, as they claim below. Unfortunately, they don't say longer than what, provide an estimate of rate/reach, or release test data. http://bit.ly/gfastnok

Single port G.fast: The fiber extender http://bit.ly/gfastone
Sckipio's single port G.fast is an ideal solution if you need hundreds of megabits a few hundred meters from fiber and digging to extend it is too expensive. A telco engineer tells me that is a common situation. It's easy to imagine a small radio station with a dozen people on staff across a highway from fiber, or three homes about 200 meters beyond a telco GPON network. 
     I live about 50 meters from Columbia's Engineering School, with probably a terabit of connectivity. Verizon can't deliver more than 6 megabits to the fifty apartments in my building (Columbia-owned) or the ~800 more within 150 meters. If you could find a simple wire run from Columbia and connect that copper line to a G.fast unit in the basement, everyone in the building could have several hundred megabits 95+% of the time.http://bit.ly/gfastone

Eric Small of AT&T: G.fast is essential. http://bit.ly/gfessential
WTTR + G.fast for coax. In an interview with Sean Buckley, Small said “The other thing that we have separately talked about is we’re exploring the use of G.fast. That technology can work over coax or twisted pair so that’s an essential companion way to deliver service where a property does not have Cat 5 or Cat 6.” DirecTV has millions of lines with an antenna on the roof and either coax or ethernet cable throughout the building. 
     They want to use G.fast for 500 megabits or more but continue to be coy about whether they will turn their G.fast trials into volume deployment.http://bit.ly/gfessential

BT delays G.fast rollout 6-9 months to 2H 2017http://bit.ly/GF6late
Pioneers get arrows in their back and schedules do slip. 
BT had originally promised to start their 10M home rollout late this year or early next. They are expanding the trials to 140,000 homes.  BT wants 48 or 96 ports while today's tech only supports 16-24 ports. They also want the higher power and longer reach of the Amendment 2/3 chips. 
    The original plan, promised by CEO Gavin Patterson, would go to local distribution points for speeds generally 500+ megabits. Then the bean counters jumped in and insisted on using the existing cabinets, Trevor Linney and a strong team of BT engineers did the research to go 300 meters rather than 100 meters, now in the standard. I'm going to call the downstream speed 200+ megabits, rather than the "up to 330" in the BT pr. It's time to use actual speeds that most users can achieve. http://bit.ly/GF6late

Nokia & Huawei win BT's (delayed) G.fasthttp://bit.ly/gfbtnok
BT decides to stick with the big guys. Alcatel-Nokia and Huawei have been #1 & #2 in DSL for a decade, both with excellent products. They both jumped in early to G.fast and their gear works well. They've now won the next stage of BT's 10M home servable G.fast offering, another 100,000 homes in the next six months.  BT's Seeley is hopeful they will get production amendment 2/3 chips, but their main supplier Broadcom is not committed to delivering the chips so soon. Ray Le Maistre, a first rate British reporter, believes Adtran has a chance to get back in at the next stage of DSLAM procurement. BT has surprisingly few choices. The vendor community has shrunk drastically. I know only four DSLAM makers and two chip vendor likely to be ready to serve a customer like BT. http://bit.ly/gfbtnok
