We are thrilled to finally unveil our latest white paper: Broadband At the Speed of Light: How Three Communities Built Next-Generation Networks. This report was a joint effort of the Institute for Local Self-Reliance and the Benton Foundation.

We have chronicled how Bristol's BVU Authority, Chattanooga's EPB, and Lafayette's LUS built some of the most impressive broadband networks in the nation. The paper presents three case studies and then draws lessons from their common experiences to offer advice to other communities.

Here is the press release:

The fastest networks in the nation are built by local governments, a new report by the Institute for Local Self-Reliance and Benton Foundation reveals

Chattanooga, Tennessee, is well known for being the first community with citywide access to a “gig,” or the fastest residential connections to the Internet available nationally. Less known are Bristol, Virginia, and Lafayette, Louisiana – both of which now also offer a gigabit throughout the community.

A new report just released by the Institute for Local Self-Reliance (ILSR) and the Benton Foundation explains how these communities have built some of the best broadband networks in the nation. Broadband At the Speed of Light: How Three Communities Built Next-Generation Networks is available here.

“It may surprise people that these cities in Virginia, Tennessee, and Louisiana have faster and lower cost access to the Internet than anyone in San Francisco, Seattle, or any other major city,” says Christopher Mitchell, Director of ILSR’s Telecommunications as Commons Initiative. “These publicly owned networks have each created hundreds of jobs and saved millions of dollars.”

“Communities need 21st century telecommunications infrastructure to compete in the global economy,” said Charles Benton, Chairman & CEO of the Benton Foundation. “Hopefully, this report will resonate with local government officials across the country.”

Mitchell is a national expert on community broadband networks and was recently named a “Top 25 Doer, Dreamer, and Driver” by Government Technology. He also regularly authors articles at MuniNetworks.org.

The new report offers in-depth case studies of BVU Authority’s OptiNet in Bristol, Virginia; EPB Fiber in Chattanooga, Tennessee; and LUS Fiber in Lafayette, Louisiana. Each network was...

An unfortunately common argument used against community fiber networks is that everything will be wireless in the future. This was used frequently last year in North Carolina by defenders of the pro-TWC legislation to create new barriers against community fiber networks.

The technical among us may want to get into the math theory with the Shannon-Hartley theorem to explain why wired is more reliable than wireless and therefore capable of much higher capacity.

Others might point that wireless will have less capacity because a wireless connection is really a wired connection to a tower somewhere that is then shared among hundreds or thousands of other users. Empirically, there is no wireless connection that beats fiber-optics.

But if you are looking for an entity that is intimately familiar with both wired and wireless, you might ask Verizon. Verizon is rolling out its LTE wireless network (arguably the best large scale wireless network in the country) and has millions of customers on its fiber-optic FiOS wired network. Verizon says the future needs fiber-optics to the home and wireless in the air:

"If you get underneath what's driving the fiber in the metropolitan markets it has been the need for increased video, increased reliability and security for customers," Seidenberg said. "The way we think about it is even though we have this great 4G mobile network, you still need to have fiber to the premises because we think your home will utilize a Gigabit of bandwidth."

...

"The way we look at it is we want to get fiber to as many business premises and cover as much as the footprint as we can and we believe everyone else going to do the same thing in other parts of the country," Seidenberg said. "If the incumbents or the MSOs don't do it then these little companies will do it and be the entrance facilities to homes and businesses."

As folks in North Carolina consider this year's proposal to limit competition with last-generation cable and DSL networks, they should think seriously about the communities around them served by FiOS -- with much faster...

Michael Crowell, Fibrant's Director of Broadband Services, discusses the motivation behind their community fiber network (Fibrant), as well as some of the technology behind their GPON network. This is one of several similar interviews from TelecomTV.

In this interview, Crowell makes an important point: each community should not be building its own head end and should cooperate with each other to use the existing resources built by Wilson and Salisbury.

This video is no longer available.

So Comcast and Level 3 are in a peering dispute following the Netflix partnership with Level 3 to distribute their streaming movie service. Studies suggest Netflix movie streaming has become a significant chunk of Internet traffic, particularly at peak times.

A quick primer on peering: the Internet is comprised of a bunch of networks that exchange traffic. Sometimes one has to pay another network for transit and sometimes (commonly with big carriers like Comcast and Level 3) networks have an agreement to exchange traffic without charging (one reason: the costs of monitoring the amount of traffic can be greater than the prices that would be charged). (Update: Read the Ars Technica story for a longer explanation of peering and this conflict.)

Comcast claims that Level 3 is sending Comcast 5x as much traffic as Comcast sends to Level 3 and therefore wants to charge Level 3 for access to Comcast customers. Of course, as Comcast only offers radically asymmetrical services to subscribers, one wonders how Level 3 could be 1:1 with Comcast…

At Public Knowledge, Harold Feld ties the dispute to network neutrality:

On its face, this is the sort of toll booth between residential subscribers and the content of their choice that a Net Neutrality rule is supposed to prohibit.  In addition, this is exactly the sort of anticompetitive harm that opponents of Comcast’s merger with NBC-Universal have warned would happen — that Comcast would leverage its network to harm distribution of competitive video services, while raising prices on its own customers.

Susan Crawford

Susan Crawford wrote a lengthier piece about Comcast, Netflix, network neutrality, set-top boxes and NBC that is well worth reading (as is just about anything she writes).

However, for the purposes of this post, we will assume the 5x traffic imbalance is true (and unique and...

Vermonters are asking some hard questions about the federal broadband stimulus decision to throw money at a wireless network for Vermont rather than loaning money to an organization dedicated to delivering real broadband.

Senator Bernie Sanders convened a meeting to discuss the awards toward the end of October.

Senator Bernie Sanders led off his “broadband town meeting” Saturday morning at Vermont Technical College with a ringing affirmation of the need for better broadband coverage in Vermont and the nation.

However, nobody in the crowd of nearly 300 people needed to be convinced of that. What they wanted to know was whether a huge new federal grant to a private company was the right way to do it.

VTel, a small private telephone company, received a $116 million grant to build a FTTH network to serve their existing 18,000 footprint as well as a wireless network that is intended to serve the entire state.

In contrast, the East Central Vermont Fiber Network (which we have covered previously), applied for a loan to build a FTTH network to everyone in the 24 communities that have joined together to form the network. The ECFiber network would be run by a nonprofit and would repay the loan from revenue generated by selling triple-play services on the network.

Vermonters have a strong fiscal conservatism streak, which has shown up strongly in the discussions around this situation, something noted in a story leading up to the Sanders meeting:

He will get plenty of both from representatives of ECFiber, the consortium of 23 towns that has been planning a network of fiber-optic broadband to virtually every home in the White River Valley and beyond.

The organization was stung recently when its own request for a loan was not funded by RUS, which instead awarded a much larger outright grant to VTel, which is located in Springfield.

Our position at MuniNetworks, is quite similar to that of the these Vermonters: loans would be better policy than grants for broadband infrastructure.

Supporters of the wireless network, including VTel's CEO, Michel Guite, have suggested the $116 million...

Chattanooga continues to generate a lot of press since their announcement of the nation's fastest broadband speeds.

For those who crave technical details, this article from Cable 360 looks into the tech behind the network:

EPB contracted with Alcatel-Lucent as its GPON network supplier. "We've designed our network a little bit different, with our control center located where our operations center is," says Wade. "We've designed a series of fiber rings that circle our city, allowing us to have multiple 10 Gig MPLS rings, terminating in 17 communications hubs connected back with our control center."

Another article from Cable 360 (affiliate) gets into the smart-grid details of the network:

As far as the cost savings of the smart grid are concerned, users often don't realize that it costs several times more at certain times of day to generate electricity than it does at others, says EPB COO David Wade.

But perhaps the most interesting update from EPB is another window into their take rates (from Tecca.com):

We are ahead of our business plan projections for this time frame. Since our launch last September (2009), we have signed up 18,873 homes to our EPB fiber optics services. That is a 15.45% take rate. Our goal is a 35% take rate, and we believe we will reach that in 2 years. Of our EPB fiber optics customers, 81% are receiving our Fi-Speed internet service. We are still building out fiber optics as well, and our entire 600-square-mile customer service area will have access to these advanced services by the end of the this year (2010).

And finally, a short interview (audio quality is not good) with an EPB employee discussing Chattanooga's community fiber network. An interesting piece: noting that EPB views all employees as ambassadors of their product and offered them public speaking training.

The May/June issue of Broadband Properties Magazine continued the Muni FTTH snapshot series, this time focusing on a small network in Auburn, Indiana. The network currently has 500 subscribers as it continues its buildout, which is scheduled to finish in 2011. By 2013, the business plan calls for serving 3200 subscribers.

The public power utility, Auburn Electric, has been using fiber-optics for internal use since 1985, but only began offering services to some customers in the mid 2000's. In 2007, they began deploying the FTTH. In 2005, their services kept an employer in town with a $7 million payroll.

Cedar Falls, Iowa, is the latest of a number of publicly owned cable networks that are upgrading to FTTH. Cedar Falls has been planning this for some time, squirreling away net income over the years as it ran surpluses to help afford the costly upgrade. A story in the WCF Courier notes it will cost $17 million and is expected to be completed in 2012. The bonds used to finance the project will be repaid over 10 years.

When I last spoke to folks in Cedar Falls, they had massive take rates - bolstered by local service that Mediacom could not compete with. Cedar Falls Utilities (CFU) had already been offering fiber services to local businesses and will be expanding that to the entire area. According to an article in the Cedar Falls Times, the utility had already been installing FTTH capability into greenfield developments, so they have certainly planned for this transition.

Motivation for the upgrade seems to be the faster broadband speeds and more capacity for HD channels. The Utility also noted that needed bandwidth has been doubling every year -- a likely reason they opted for FTTH rather than a cheaper DOCSIS3 upgrade that would not offer the same scalability as FTTH (and DOCSIS3 is much more constrained in upstream capacity).

The Cedar Falls Times article explains the benefits of FTTH over HFC:

An HFC plant uses thousands of active devices (such as amplifiers) to keep data flowing between the customer and the service provider. Any one of these devices can fail, interrupting service. In contrast, the all-fiber plant will be a passive optical network, with no active components between the distribution center and the end user. Fewer “moving parts” means fewer points of failure and a more reliable system.

CFU puts community needs first:

“We know from experience that economic growth comes to cities that keep their infrastructure up to date, whether it’s roads, water, electricity or broadband,” said Krieg [CFU General Manager]. “CFU is going to do what it takes to make sure Cedar Falls has leading-edge communications technology, and maintain economical rates for internet and video services.”

The network was launched in 1996, one of the first...
