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 News 

A dozen telcos have deployed 10's of thousands of G.fast lines. It works. 

Centurylink: G.fast works as promised http://bit.ly/GFcentury
Curtis Frankenfeld tells me G.fast produced "No disappointments on performance. The results in the field on real cable approach the lab results The results using coax were flawless, with slightly better performance than twisted pair. The installers only had to do a small amount of repair, splitter removal and similar."  http://bit.ly/GFcentury

*** HFR and Sckipio Announce World’s First 24-Port G.fast DPU
Sckipio Technologies and South Korean network infrastructure equipment maker, HFR, Inc. announce the world’s first G.fast distribution point unit (DPU) that supports up to 24 subscribers in a single DPU. Visit the Sckipio booth (D20)  London, October 18 – 20, 2016http://bit.ly/Sckipio (ad)

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

*** Sckipio Technologies, the leader in G.fast, announces the first single-port G.fast DPU design. The solution acts like virtual fibre by extending GPON networks with twisted pair or coax. A very thin management layer allows operators to keep their existing GPON management layer. Sckipio makes it effortless to add G.fast to any GPON network.

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
