Although the English needs a little work, Korean broadband delivers a reality most Americans can only imagine.

South Korea has launched a nationwide broadband upgrade to rid themselves of 100Mbps service for $38 a month, claiming those speeds and prices are no longer sufficient for Korea’s new digital economy.

By the end of 2012, South Korea intends to connect every home in the country to the Internet at one gigabit per second and slash the monthly price to just $27 a month.

That’s more than 200 times faster than speeds enjoyed by most Americans, who pay an average of $46 a month — nearly double Korea’s planned price. Even more galling for Canadians — those speeds and prices are for completely unlimited access.

Stop the Cap! reader John in Victoria, B.C., thinks South Korea’s broadband improvements call out just how ludicrous Canada’s Internet Overcharging schemes really are.

“If the Canadian Radio-TV and Telecommunications Commission ultimately allows $2 per gigabyte in overlimit fees, we would have to pay $5,184,000 per month for the same thing,” John says. “If this comparison doesn’t make people want to chuck the CRTC, what will?”

For the government of South Korea, which is spearheading the Internet expansion effort, broadband has become a national priority for the fast-growing Korean economy.

South Korea historically trailed Japan’s economic post-World War II revival for decades, but no more. The country, which used to be poorer than the Communist People’s Republic of Korea to the north, has grown to the world’s 13th largest economic power, and has designs on being a world leader in the transition to the digital/information economy. They are already ahead of North America, with an advanced broadband platform that can sustain concepts like cloud computing that are just getting off the ground in Canada and the USA.

The KCC is spearheading Korea's broadband advancements

Only the most rural parts of Korea still rely on copper phone wires delivering DSL service, now considered archaic. Most of the country is now wired for fiber optics, making a transition from 100Mbps-1Gbps relatively simple. With new laser technology, existing fiber cables can transmit faster speeds, and when fiber is laid in the country, extra strands are buried for future use. The costs of burying 10 or 100 or 1,000 strands come mostly from labor, not the wiring.

Private electronics companies are strong proponents of the infrastructure upgrades, and service providers are on board to deliver the service. That is in marked contrast with providers in the United States and Canada who consider expensive upgrades an unnecessary proposition.

“Providers in the USA and Canada defend their existing networks as ‘good enough for average residential use,’ something that would be laughed away here in Korea or in Japan,” Dr. Park Sung-Jin, a Korean broadband researcher who travels between Seoul and Los Angeles tells Stop the Cap! “Large providers like AT&T cannot afford to lose their propaganda arguments of broadband sufficiency because if they did, they would lose face and be forced to transform broadband in the USA at the expense of their enormous profits.”

“In Asia, we would never allow our providers to dictate the national broadband policies of the country, and our discussions are long past arguing over what speeds are correct,” Park says.  “Now we’re arguing about how to bring the cost down.”

Japan delivers 1Gbps broadband service for $70 a month, a price scoffed at by Choi Gwang-gi, the 28-year old Korean now in charge of the Korea’s expansive broadband plans.

“I can’t imagine anyone in Korea paying that much,” Choi told the New York Times. “No, no, that’s unthinkable.”

A pilot gigabit project initiated by the government is underway with 5,000 households in five South Korean cities. Each customer pays about 30,000 won a month, or less than $27.

“A lot of Koreans are early adopters,” Mr. Choi said, “and we thought we needed to be prepared for things like 3-D TV, Internet protocol TV, high-definition multimedia, gaming and videoconferencing, ultra-high-definition TV, cloud computing.”

Meanwhile, according to Dr. Park, North American providers like Bell, Rogers, and Comcast are spending millions trying to convince lawmakers in both countries that such speeds are wholly unnecessary.

“The United States and Canada are the worst, with providers spending countless millions themselves and through their lackey trade associations and illicit ‘consumer groups’ working for them trying to convince lawmakers American broadband isn’t so bad after all, but it is,” Park says. “They routinely claim any country that is ahead of the U.S. or Canada is a ‘special case’ because of urban density or government subsidies, but that can’t explain away all of the disparity in speeds and accessibility, only money and monopoly profits can.”

Both Romania and Latvia now beat Canada and the USA in broadband speeds and pricing, and North America’s dominance in a digital economy could be at risk.

Closer to home Don Norman, co-founder of the Nielsen Norman Group in Fremont, Calif., told the Times Korea is on the right track.

“The gigabit Internet is essential for the future, absolutely essential, and all the technologists will tell you this,” said Norman. “We’re all going to be doing cloud computing, for example, and that won’t work if you’re not always connected. Games. Videoconferencing. Video on demand. All this will require huge bandwidth, huge speed.”

In Canada, such predictions have given companies like Bell an excuse to engage in a national Internet Overcharging scheme they claim will help pay for building these kinds of future networks. But other countries around the world now deliver speeds Canada only promises their citizens, without overcharging them to pay for it.

“Charging for broadband traffic would be like you or I charging for the wind — it has no real value except in the eyes of the people who stand to profit from it,” Park said.

Will people notice a difference between 100Mbps and 1Gbps? Koreans say they will, according to the New York Times.

One of the customers already connected to Mr. Choi’s pilot program is Moon Ki-soo, 42, an Internet consultant. He got a gigabit hookup about a year ago through CJ Hellovision, although because of the internal wiring of his apartment building his actual connection speed clocks in at 278 megabits a second.

But even that speed — about a quarter-gigabit — has him dazzled.

“It is so much more convenient to watch movies and drama shows now,” he told the newspaper.

John Linton, CEO Exetel

Australia’s planned National Broadband Network (NBN) delivering the country access to broadband speeds up to 1Gbps face many of the same criticisms American municipal providers hear when incumbent commercial providers face imminent competition from fiber broadband.

But nobody can top the venomous spray of Exetel’s CEO John Linton, who called the entire concept of public broadband for the public good “a load of crap” and those behind it a mix of ‘thugs,’ ‘pretenders,’ and generally incompetent and stupid.

Linton’s Internet Service Provider delivers broadband to most of its customers over Telstra landlines, using DSL.  But the company has grudgingly agreed to participate in the NBN project, even while still despising it to the core.

Exetel’s pricing on NBN’s fiber network charges for speed and usage.  Much like cable broadband, Exetel delivers much faster downstream speeds (up t0 100Mbps), with upload speeds maxing out at 8Mbps. The higher the speed, the higher the monthly access fee.  Users receive no usage allowance, paying fees per gigabyte for all of their usage.  Exetel still reserves the right to throttle customer speeds for certain online applications, and “traffic shape” users based on their usage.

In Tasmania, Exetel has introduced a 25/2Mbps broadband plan with no usage allowance — but no monthly access fee either — charging a flat $2 per gigabyte of usage.

Exetel Fiber Pricing In Tasmania

Linton spews most of his angry commentary on his personal blog, which he closed to non-Exetel customers unless they made a $20AUS contribution to the company’s endangered wildlife protection programs.  But he rarely pulls punches in public either.

Is this Australia's broadband future?

A sampler:

With wireless broadband waiting in the wings, those excited by NBN’s 1Gbps speeds are “unthinking and just plain stupid, pretty much along the same lines as the stone age cargo cult dwellers in the jungles of New Guinea are excited about the next ‘goods drop’ from the strange colored bird.”

Australia’s aging population, “who don’t play computer games or get a surrogate sex life from pornography” have zero interest in getting terabyte broadband speeds, making the whole endeavor a giant waste of money.

“The number of people who want 100Mbps are almost none today and aren’t going to be very many in five years time.   Probably 40-50% of people today will never want to use a piece of fiber […] and they’re certainly not gamers playing, or those other things.  They’re the other half of Australia that has a life rather than a half life.”

On the results of the recent election and the decision to move forward with the NBN: “God help us all.”

On Communications Minister Stephen Conroy (Australia’s version of FCC Chairman Julius Genachowski): “He was his usual mixture of bewilderment, ignorance and barely concealed thuggery, but I was amused at his reference to Exetel (not by name).” Linton wrote on his blog. “While I’m grateful for the ‘free plug’ I thought it was an obvious example of “straw clutching” if it wasn’t based on appallingly bad briefing, which I would doubt, because for him to have been aware of any actual pricing would have required some sort of briefing,” added Linton.

On NBN co-chief Mike Quigley, who will help manage NBN service: “Is [Mike Quigley] god? Can he reverse 100 years of telecommunications going one way and say, ‘Oh, I’m Mike Quigley, and I haven’t worked here in 30 years, I know nothing about running major networks, but someone has paid me $2 million a year so I can pretend I can’.  The only one who can do it is Telstra. It would do it cheaper than a bloody government.”

Linton blames all of the talk about a publicly-owned broadband network for the decrepit state of Australia’s commercial broadband market, claiming it dried up private investment in new ADSL products: “The situation as I see it is that the suppliers — Telstra, Optus, AAPT — are not really investing in anything new, especially when you’re referring to ADSL type broadband products. The current suppliers are holding on to the margins they have at the moment, and if anything they will seek to increase them rather than reduce them,” says Linton.

Since nearly every broadband user in Australia knows Linton hates fiber broadband, what technology does he believe represents Australia’s future?

Or this?

3G wireless.

“Most people that I know, including me, put a much higher priority on mobility than they do on speed,” he told ZDNet. “The average person needs a 100Mbps internet connection about as much as they need to have their arms amputated.”

While mobility is important, his critics charge, there is no way 3G wireless can deliver Australia its broadband future.  Service is not ubiquitous across the country, speeds are far below even what DSL offers, streaming multimedia is challenging at best, and the usage fees and limits that accompany wireless service plans in the south Pacific would create an even greater divide between those who can afford wireless broadband, and those who cannot.

A report released yesterday by the Bureau of Statistics shows Australians are downloading more data than ever before, increasing more than 50 percent in the second quarter compared to the same period last year. The amount of data downloaded every three months is now 11 times higher than March 2005 and 126 times higher than March 2002.

Australia’s National Broadband Network is open to all Internet Service providers that wish to participate, reselling their broadband plans using NBN’s infrastructure.

EPB’s new 1Gbps municipal broadband service is causing some serious embarrassment to the telecom industry.  Since last week’s unveiling, several “dollar-a-holler” telecom-funded front groups and trade publications friendly to the industry have come forward to dismiss the service as “too expensive,” delivering speeds nobody wants, and out of touch with the market.

The “Information Technology and Innovation Federation,” which has historically supported the agenda of big telecom companies, has been particularly noisy in its condescending dismissal of the mega-speed service delivered in Chattanooga, Tenn.

Robert Atkinson, president of ITIF, undermines the very “innovation” their group is supposed to celebrate.  Because it doesn’t come from AT&T or Verizon, it’s not their kind of “innovation” at all.

“I can’t imagine a for-profit company doing what they are doing in Chattanooga, because it’s so far ahead of where the market is,” Atkinson told the New York Times.

“Chattanooga definitely is ahead of the curve,” Atkinson told the Times Free Press. “It’s like they are building a 16-lane highway when there is a demand for only four at this point. The private companies probably can’t afford to get that far ahead of the market.”

Bernie Arnason, formerly with Verizon and a cable industry trade association also dismissed EPB’s new service in his current role as managing editor for Telecompetitor, a telecom industry trade website:

Does anyone need that speed today? Will they in the next few years? The short answer is no. It’s kind of akin to people in the U.S. that buy a Ferrari or Lamborghini – all that power and speed, and nowhere to really use it. A more apropos question, is how many people can afford it – especially in a city the size of Chattanooga?

[…]Will there be a time when 1 Gb/s is an offer that is truly in demand? More than likely, although I still find it hard to imagine it being really necessary in a residential setting – I mean how many 3D movies can you watch at one time? Maybe a service that bursts to 1 Gb/s in times of need, but an always on symmetrical 1 Gb/s connection? Truth be told, no one really knows what the future holds, especially from a bandwidth demand perspective.

Arnason admits he doesn’t know what the future holds, but he and his industry friends have already made up their minds about what level of service and pricing is good enough for “a city the size of Chattanooga.”

Comcast’s Business Class broadband alternative is priced at around $370 a month and only provides 100/15Mbps service in some areas.  Atkinson and Arnason have no problems with that kind of innovation… the one that charges more and delivers less.

For groups like the ITIF, it’s hardly a surprise to see them mount a “nobody wants it or needs it”-dismissive posture towards fiber, because they represent the commercial providers who don’t have it.

Fiber Embargo

The Fiber-to-the-Home Council, perhaps the biggest promoter of fiber broadband delivered straight to customer homes, currently has 277 service provider members. With the exception of TDS Telecom, which owns and operates small phone companies serving a total of 1.1 million customers in 30 states, the FTTH Council’s American provider members are almost entirely family-run, independent, co-op, or municipally-owned.

Companies like American Samoa Telecommunications Authority, Hiawatha Broadband Communications, KanOkla Telephone Association Inc., and the Palmetto Rural Telephone Cooperative all belong.  AT&T, CenturyLink, Frontier, Verizon, and Windstream do not.  Neither do any large cable operators.

While not every member of the Council has deployed fiber to the home to its customers, many appreciate their future, and that of their communities, relies on a high-fiber diet.

EPB’s announcement of 1Gbps service was made possible because it operates its service over an entirely fiber optic network.  Company officials, when asked why they were introducing such a fast service in Chattanooga, answered simply, “because we can.”

The same question should have been directed to the city’s other providers, Comcast and AT&T.  Their answer would be “because we can’t… and won’t.”

Among large providers, only Verizon has the potential to deliver that level of service to its residential customers because it invested in fiber.  It was also punished by Wall Street for those investments, repeatedly criticized for spending too much money chasing longer term revenue.  Wall Street may have ultimately won that argument, because Verizon indefinitely suspended its FiOS expansion plans earlier this year, despite overwhelmingly positive reviews of the service.

So among these players, who are the real innovators?

The Phone Company: Holding On to Alexander Graham Bell for Dear Life

Last week, Frontier Communications told customers in western New York they don’t need FiOS-like broadband speeds delivered over fiber connections, so they’re not going to get them.  For Frontier, yesterday’s ADSL technology providing 1-3Mbps service in rural areas and somewhat faster speeds in urban ones is ‘more than enough.’

That “good enough for you” attitude is pervasive among many providers, especially large independent phone companies that are riding out their legacy copper wire networks as long as they’ll last.

What makes them different from locally-owned phone companies and co-ops that believe in fiber-t0-the-home?  Simply put, their business plans.

Companies like Frontier, FairPoint, Windstream, and CenturyLink all share one thing in common — their dependence on propping up their stock values with high dividend payouts and limited investments in network upgrades (capital expenditures):

Perhaps the most important metric for judging dividend sustainability, the payout compares how much money a company pays out in dividends to how much money it generates. A ratio that’s too high, say, above 80% of earnings, indicates the company may be stretching to make payouts it can’t afford.

Frontier’s payout ratio is 233%, which means the company pays out more than $2 in dividends for every $1 of earnings! But this ignores Frontier’s huge deferred tax benefit and the fact that depreciation and amortization exceed capital expenditures — the company’s actual free cash flow payout ratio is a much more manageable 73%. Dividend investors should ensure that benefit and Frontier’s cash-generating ability are sustainable.

In other words, Frontier’s balance sheet benefits from the ability to write off the declining value of much of its aging copper-wire network and from creative tax benefits that might be eliminated through legislative reform.

The nightmare scenario at Frontier is heavily investing in widespread network upgrades and improvements beyond DSL.  The company recently was forced to cut its $1 dividend payout to $0.75 to fund the recent acquisition of some Verizon landlines and for limited investment in DSL broadband expansion.

Frontier won’t seek to deploy fiber in a big way because it would be forced to take on more debt and potentially cut that dividend payout even further.  That’s something the company won’t risk, even if it means earning back customers who fled to cable competitors.  Long term investments in future proof fiber are not on the menu.  “That would be then and this is now,” demand shareholders insistent on short term results.

The broadband expansion Frontier has designed increases the amount of revenue it earns per customer while spending as little as possible to achieve it.  Slow speed, expensive DSL fits the bill nicely.

The story is largely the same among the other players.  One, FairPoint Communications, ended up in bankruptcy when it tried to integrate Verizon’s operations in northern New England and found it didn’t have the resources to pull it off, and delivered high speed broken promises, not broadband.

Meanwhile, many municipal providers, including EPB, are constructing fiber networks that deliver for their customers instead of focusing on dividend checks for shareholders.

Which is more innovative — mailing checks to shareholders or delivering world class broadband that doesn’t cost taxpayers a cent?

Cable: “People Don’t Realize the Days of Cable Company Upgrades are Basically Over”

While municipal providers like EPB appear in major national newspapers and on cable news breaking speed records and delivering service not seen elsewhere in the United States, the cable industry has a different story to share.

Kent

Suddenlink president and CEO Jerry Kent let the cat out of the bag when he told investors on CNBC that the days of cable companies spending capital on system upgrades are basically over.

“I think one of the things people don’t realize [relates to] the question of capital intensity and having to keep spending to keep up with capacity,” Kent said. “Those days are basically over, and you are seeing significant free cash flow generated from the cable operators as our capital expenditures continue to come down.”

Both cable and phone companies have called a technology truce in the broadband speed war.  Where phone companies rely on traditional DSL service to provide broadband, most cable companies raise their speeds one level higher and then vilify the competition with ads promoting cable’s speed advantages.  Phone companies blast cable for high priced broadband service they’re willing to sell for less, if you don’t need the fastest possible speeds.  But with the pervasiveness of service bundling, where consumers pay one price for phone, Internet, and television service, many customers don’t shop for individual services any longer.

With the advent of DOCSIS 3, the latest standard for cable broadband networks, many in the cable industry believe the days of investing in new infrastructure are over.  They believe their hybrid fiber-coaxial cable systems deliver everything broadband consumers will want and don’t see a need for fiber to the home service.

Their balance sheets prove it, as many of the nation’s largest cable companies reduce capital expenses and investments in system expansion.  Coming at the same time Internet usage is growing, the disparity between investment and demand on broadband network capacity sets the perfect stage for rate increases and other revenue enhancers like Internet Overcharging schemes.

Unfortunately for the cable industry, without a mass-conversion of cable-TV lineups to digital, which greatly increases available bandwidth for other services, their existing network infrastructure does not excuse required network upgrades.

EPB’s fiber optic system delivers significantly more capacity than any cable system, and with advances in laser technology, the expansion possibilities are almost endless.  EPB is also not constrained with the asynchronous broadband cable delivers — reasonably fast downstream speeds coupled with paltry upstream rates.  EPB delivers the same speed coming and going.  In fact, the biggest bottlenecks EPB customers are likely to face are those on the websites they visit.

EPB also delivered significant free speed upgrades to its customers earlier this year… and no broadband rate hike or usage limits.  In fact, EPB cut its price for 100Mbps service from $175 to $140.  Many cable companies are increasing broadband pricing, while major speed upgrades come to those who agree to pay plenty more to get them.

Which company has the kind of innovation you want — the one that delivers faster speeds for free or the one that experiments with usage limits and higher prices for what you already have?

No wonder Big Telecom is embarrassed.  They should be.

[flv width=”640″ height=”500″]http://www.phillipdampier.com/video/EPB Interviews 9-20-10.flv[/flv]

EPB and Chattanooga city officials appeared in interviews on Bloomberg News and the Fox Business Channel.  CNET News also covered EPB’s 1Gbps service, introduced last week.  (12 minutes)

Although the price tag may be too rich for your blood, a municipally-owned utility today announced it was bringing America’s fastest broadband to residents and businesses in greater Chattanooga, Tenn., delivering 1 gigabit per second access for $350 a month.

That’s 200 times faster than what the average American broadband consumer receives, and just a fraction of what many Chattanooga area businesses pay other providers for that level of service

“One gigabit broadband service could be compared to the introduction of electric power in the 1930’s. At that time, most people saw electricity as an alternative to the oil lamp for producing light but the larger implications were soon realized,” said Harold DePriest, president and CEO of EPB. “We believe true high-speed Internet access, to both our urban and rural areas, will make Chattanooga the frontier of a new generation of opportunity and provide our community with a platform for engineering the 21st century.”

The mega-fast fiber-to-the-home broadband comes not from a multi-billion dollar private company like AT&T, Verizon, Comcast, or Time Warner Cable, but rather a small city-owned utility that has served Chattanooga’s electricity needs since 1939.

Just over one year old, EPB Fiber Optics is the latest service from the city’s municipal utility. EPB’s fiber broadband network was built after overcoming legal actions filed to stop it by Comcast and the state’s cable lobbyist group.

Since launching service in 2009, EPB’s fiber division has won over 169,000 residents in its 600 square mile service area in Tennessee and northwest Georgia.  This despite the presence of Comcast and AT&T’s U-verse operations, both competing with EPB for customers.  Neither the cable or phone company comes close to matching the speeds and demand EPB has managed to achieve.  In fact, AT&T’s U-verse launch week event in July was marred when an AT&T technician pepper-sprayed a local woman’s pets, and she wasn’t even a customer.

Google acknowledged the arrival of another provider extending 1Gbps broadband to Americans, noting it is still in the process of selecting locations for its own “Think Big With a Gig” 1Gbps fiber service.

“We’re excited to see enthusiasm for ultra high-speed broadband,” spokesman Dan Martin said in an e-mail statement. “It’s clear that people across the country are hungry for better and faster Internet access.”  Chattanooga now joins Hong Kong and just a handful of other cities delivering gigabit broadband.

Atkinson

A broadband industry trade group funded by large telecommunications companies was left making excuses for EPB’s thunder-stealing announcement.

“I can’t imagine a for-profit company doing what they are doing in Chattanooga, because it’s so far ahead of where the market is,” Robert D. Atkinson, president of the Information Technology and Innovation Foundation told the New York Times.

Atkinson is closely involved with several industry backed front groups, including the Alliance for Public Technology (AT&T & Verizon) and the Internet Education Foundation (Comcast & Verizon).

The irony of a telecom industry group that supposedly celebrates broadband innovation downplaying today’s achievement by EPB was not lost on DePriest.

When the Times asked DePriest why EPB would offer such a high speed service, DePriest said, “The simple answer is because we can.”

EPB’s latest announcement throws down the gauntlet against the idea that broadband innovation comes only from large commercial telecom companies.  Phone and cable operators claim their record of innovation will be harmed if municipal providers like EPB are able to offer service, claiming “private investment will dry up.”

It’s the same argument they use for deregulation and minimal oversight.  Yet it was a municipally-owned provider that established a network far superior to what Comcast and AT&T have in Chattanooga, launched America’s first residential 150Mbps service, and today launched America’s first residential 1Gbps broadband service.  EPB charges lower everyday prices for its bundle of TV, phone, and broadband services, too.

The cost to taxpayers?  Nothing.

Local residents can’t wait to get the service.

Keith in Soddy Daisy, Tenn., commented about EPB service: “I’m still waiting on it to become available where I live. It’s getting close because I see them stringing fiber all over the place. The crazy thing is that there are people in their service footprint that only have dial-up. Can you imagine going from having dial-up to having 1 Gbps symmetrical fiber as an option?”
