EnergiaJapan's Energia, the ISP of a regional electric company, has been running a small deployment of for a year. They like it so much they signed on with Nokia to be a Japanese distributor. Alongside the giants NTT, KDDI, & Softbank there remain many smaller companies delivering broadband. 

Energia, the electric company for the Hiroshima region, years ago entered the ISP business. Distributing equipment is a natural move. After Fukushima, diversification must be particularly attractive for electric companies, especially in Hiroshima. They are decommissioning reactor #1 at their Shimane Nuclear Power Station, which will take thirty years. They hope to restart #2, where corrosion was recently discovered. 

Now that is proven to deliver 500-800 megabits, it allows the smaller companies to compete with the fiber to the basement of the giants.

Half of the Japanese fiber to the home actually terminated in the basement and used 100 megabit VDSL to reach apartments in the "mansions" most Japanese live in. It's a market Huawei, Nokia, and ZTE hope to reach. I don't believe any of the domestic suppliers offer I haven't seen much presence for Americans Calix and Adtran.

For maximum speed in countries with a lot of fiber home, Japanese and I believe Korean companies used 30 MHz VDSL rather than the 17 MHz the Europeans chose. Sckipio has optimized their chip to work with 30 MHz VDSL but I don't know which chip Nokia is using.

Japan has been a famously insular society, closed to all outsiders for 250 years until the U.S. sent warships.  Six Keiretsu dominated the economy after World War II and foreigners were all but required to work with one of their trading companies.  

NTT bought almost exclusively from domestic suppliers, giving companies like NEC a strong, protected base. Japan often had different standards that only local companies would meet. In ADSL, they required chips that met Annex C, designed to work well with the Japanese ISDN gear. The DSLAMs were all from domestic suppliers although the chips came from Centillium in California.

I'm heard informally the "Japan First" attitude is changing. Foreign Minister Fumio Kishida said APEC members must show a “strong commitment” to free trade, since Trump won the U.S. presidential election on Nov. 8. “The world economy faces various downside risks and skeptical views about free trade are spreading,” Kishida told Thursday’s session. “It’s time for APEC to show a strong commitment to free trade and contribute to sustainable growth and prosperity in the Asia-Pacific region.”

Nokia and Energia Communications sign distributor agreement for fixed ultra-broadband access technology in Japan

  • Partnership has grown from a successful commercial deployment to a reseller model for next generation ultra-broadband access in the country    

Tokyo, Japan - Nokia has signed a distributor agreement with Energia Communications (EneCom) to sell its fixed ultra-broadband access technology in Japan. EneCom, Nokia's first customer for next-generation broadband access technology in the country, will now become the reseller for the fixed access technology, making it available nationwide across Japan. is a technology that delivers customers fiber-like speeds over copper cable over short distances, such as, for instance, in apartment buildings with no fiber connections. The new service in EneCom's portfolio will enable the company to expand its business and interests in the utility service provider space by offering a fast, easy and economical way to replace traditional VDSL2 technology and offer subscribers a choice of higher speed access packages.

Satoshi Kumagai, CEO of Energia Communications, said: "Ten months ago we became Nokia's first technology customer in Japan and one of the first customers worldwide. We have been very happy with the service and have complete trust in Nokia's capability and strengths of its fixed access business, which is why we decided to take the relationship forward as a successful business partnership/reseller model." 

Jae Won, head of Nokia in Japan, said: "This strategic partnership with EneCom will increase deployments in Japan, providing real benefits to subscribers who might otherwise be unable to enjoy ultra-broadband speeds. Japan is a very important market to us, and we look forward to a successful venture that will boost local economies."

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."
