AT&T 35% Down-Sizing of U-Verse Claim Apparently a Mistake
Friday, 26 July 2013 11:23

AT&T's U-Verse ClaimsFinancials are contradictory. A top analyst told me a few days ago that AT&T reached less than half their locations with U-Verse, contradicting years of claims that they were going over and reached 60%.

G.fast Will Not Bring You a Gigabit
Wednesday, 17 July 2013 00:08

News stories talk gigabitReal aim is 250 megabits for a long block. Stories across the tech press picked up the ITU press release headline of 1Gbit/s, but those contemplating deployment will be happy to get a quarter of that speed. Acceptance of the standard has slipped to 2014 and product until 2015, so it will be years before we discover whether the $100's of millions going into research will pay off.

Huawei in 15 Vectoring Trials

Alcatel claimed 1M lines shipped so Huawei claims 1.2M. Nearly none turned on. The carriers are training their people, building systems and swatting bugs, so actually very few vectored customers are connected. There are perhaps a few tens of thousands of actual vectored lines in the world.

Chinese Supercomputer Twice as Fast as Any Other

TH-2No doubt China is in the front rank. It's time to put to rest the shibboleth that Chinese engineers are not innovative. U.S. Professor Jack Dongarra, a world expert on supercomputers, notes "there are a number of features of the TH-2 that are Chinese in origin, unique and interesting, including the TH-Express 2 interconnection network, the Galaxy FT-1500 16-core processor, the OpenMC programming model, their high density package, the apparent reliability and scalability of the system." http://bit.ly/14JiV4P, which includes an in-depth analysis of the design ot the TH-2.

Verizon Wants to Quickly Shut 1.5M Voice Lines
Friday, 26 July 2013 00:33

Fire Island

Not just a handful on Fire Island. The majority of the U.S., maybe as much as 60=70% by area, will soon lose landlines from Verizon and AT&T if the FCC doesn’t act. Verizon’s Tom McGuire suggests, “five percent of Verizon’s overall copper lines in service will be candidates for the current Voice Link device,” about a million and a half homes. As data is added to Voice Link, copper will disappear everywhere.

Lowell McAdam's Error in the NY Times

Lowell McAdam

Verizon CEO should have proofread article under his name. Lowell's NYT oped contains a whopping mistake, claiming in "the European Union ... today only about 2 percent of households have access to broadband networks with 100-megabit-plus speeds." http://nyti.ms/14NBNQhThe actual figure is more than twenty times higher than that, according to a report by Point-Topic for the EU http://bit.ly/16l6wDt.

Lantiq Sampling 3x3 MIMO for Faster VDSL Gateways
Monday, 13 May 2013 11:49

Supporting existing VDSL chip, extending bonding. Imran Hajimusa of Lantiq had a great demo of 4 HD channels streaming over WiFi a while back. They are now sampling and about to ship this improved WiFi, 3x3 MIMO 802.11n, a technology they purchased from Metalink. They've also upgraded their bonding capacity, which now can use VDSL profiles 17 & 30 for two line download speeds of 150-200 megabits over short loops. Their previous VDSL bonding could only do up to profile 8, for speeds under 100 megabits.  

  Telcos are screaming for reliable TV grade WiFi. I've heard claims as many as 50% of service calls are due to WiFi rather than DSL problems. When you carry your iPad to the bedroom upstairs, you don't want to lose the football game stream. Dirk Wieberneit of Lantiq reports raw WiFi speeds normally are fine, but don't often reach far enough into the home. The 3 antennas of their MIMO chips allow further reach with beamforming

“Look Out Google Fiber, $35-A-Month Gigabit Internet Comes to Vermont”
Friday, 17 May 2013 23:34

Springfield FallsWall Street Journal discovers Vermont is the fastest state. http://on.wsj.com/1848tWZ Michel Guite at Vermontel charges only $35 for a true gigabit, upstream and down. That’s not a typo: funding from the stimulus means VTel can sell a gig of active Ethernet for a DSL price. All customers get the full gigabit as their basic service. Almost 1,000 homes are connected, with another 15,000 in the coming months. I’m proud to play a modest consulting role.

   “Is there any network anywhere in the world doing something better we should learn from? Maybe in Hong Kong or Singapore?” Michel asked me two years ago. He didn’t quite believe me when I replied “no,” but judge for yourself:

  • Each home has dedicated fiber running active Ethernet at a gigabit both upstream and down. If requested, VTel has the capability of upgrading that to 10 gigabits or even 100 gigabits. No orders like that are likely for many years, however.

  • In the home, VTel uses a model of Actiontec router that actualy can deliver the gigabit. They discovered in testing that most home “gigabit” routers actually topped out at $300.

  • The Alcatel gear terminating the fiber in each exchange has a switching fabric designed to be non-blocking under essentially every likely traffic load.

  • VTel connects to major exchange points in both Boston and New York for redundancy. If the Boston bombings had shut down the net there, VTel could instantly switch to New York.

    The cost to build the network in a mostly rural territory is $3,000 to $5,000 per home. The promise by VTel to pass most of the subsidy to consumers in low prices was surely one reason they were awarded the funds.

   Unlike most U.S. networks, all customers get the maximum speed of the network. The increased bandwidth demand is real but not excessive; no home has installed 20 HD TVs just because they have a connection fast enough to feed them. Fiber operating costs are predictably lower than copper while bandwidth is now extremely cheap. The result is the operating costs of the network offering everyone a gigabit may well be lower than a 10 megabit DSL or cable network.

   “I’m moving to Vermont,” was a comment on one of the news stories.

60 Down, 18 Up as VDSL comes to France
Wednesday, 08 May 2013 17:06

LescauxMany lines do not significantly improve. As predicted, ARCEP is allowing French networks to upgrade to VDSL2. Free.fr has been using VDSL chips in DSLAMs and the Freebox for a while, so instantly could go into testing. One lucky customer tested  “Gross rate: 68420 kbp/s - 17852 kbp/s.” (Freenews) A second customer at 1500 meters actually saw a (small) drop in speed. By ARCEP estimate, only a modest minority of customers will benefit. Update 5/22 FT's Yves Parfait confirms it will be FTTH to 60% of France by 2020. Via CommDay
