One source at the Knight Center for Digital Excellence notes, "The new network owners are supposed to have a much more sustainable business model." Supposed to. Later, "Network Acquisition Company, which acquired the network, hasn't talked publicly about the details of its new plan, but it has hinted that its strategy will differ from EarthLink's." Hasn't talked publicly. Then, "[NAC and Tropos] spokespeople said the companies would talk more about the network later this month when details of the new business plan are ready." Huh.

Reardon explains digital divide issues and looks into what Wireless Philadelphia has been up to, although doesn't note that delays in EarthLink's deployment and other factors have led to just a few hundred individuals that have been assisted by the non-profit; numbers may have changed, but that was as of a few months ago. Still, Wireless Philadelphia has apparently diversified its funding sources--Reardon cites 30 now.

I think we're still coming off the doldrums of August.

That's ASCII, not hex: An article on wardriving raises security hackles by repeating some slightly overheated statements about Wi-Fi security. The article opens with a 63-character ASCII WPA passphrase, which is later described as "hex." (ASCII passphrases in WPA can be up to 63 "printable" characters - ASCII 32 to 127 - while a hex version of a 256-bit TKIP or AES password is 64 hexadecimal digits long.) The article tries to conflate Wi-Fi attacks that led to the largest set of breaches in retail credit-card systems and wardriving, a hobbyist activity that's never been looked on very favorably by law enforcement. The sense of ennui of wardriving pioneers is pretty clear; when Wi-Fi is everywhere and generally secured, it's far less interesting. The wardriver in the article convinced the reporter that a maximum-length WPA passphrase stored on a USB drive for automatic use was the best way to go. But, really, 20 characters containing letters and punctuation and no words found in a dictionary along with changing your network's SSID (network name) provides all the security you'll ever need for a home or small business. (If you need more, deploy WPA/WPA2 Personal.)

Green Wi-Fi's Senegal efforts hit snags: The folks at Green Wi-Fi are well motivated, and they're running up against all forms of security theater and bureaucracy both here and in Senegal, where they have an active project. The San Francisco Chronicle notes the group's effort to build solar-powered, self-sustaining Internet access via mesh networked nodes. Getting devices out of the country, clearing customs in Senegal, and hooking up their solar system all hit problems they're working through. As with the One Laptop Per Child program, I see a "build it and they will come" mentality in Green Wi-Fi's mission statement: the notion that providing computing power and Internet access will result in good things, rather than an effort to figure out what good things need to be achieved, and whether computers and the Internet will assist.

The network hasn't been revamped yet to focus on more complete outdoor coverage, but that should start happening soon, the company told Metro Philadelphia.

The city would like to avoid congestion pricing and tolls to manage traffic better. The system would allow parking pricing and durations to change dynamically. San Francisco is investing nearly $100m in an overall congestion reducing program, SFpark. This article cites an expert who estimates 30 percent of core business district traffic is from folks searching for a parking spot.

An embedded device with a 5-to-10-year battery lifespan relies information about parking availability and traffic speed through a mesh network.

It's unfortunate that such applications weren't in place when San Francisco was thinking about Wi-Fi public access. The intelligent integration of necessary city services that require a wireless backhaul with a public access Wi-Fi network could be a viable model. But early RFPs were focused entirely on public access and SF's contract with EarthLink excluded any linkage between the public Wi-Fi network and any municipal business.

Oakland County, Mich., project officially "on hold": For "on hold," read, "never going to be built." The pilot area in seven communities has been turned off, and MichTel has been unable to obtain the $70-odd million they project needed to build out the county-wide service. The state's ongoing reliance on the automotive industry makes it a hard sell to commit public dollars in advance of a return on those dollars, too.

Virgin Mobile buys Helio: The last vestiges of EarthLink's three-pronged approach to fighting the wireline monopoly appears to be at an end. EarthLink pushed its 50-50 partnership with SK Telecom in mobile virtual network operator (MVNO) Helio as one prong; its municipal Wi-Fi division as another; and its DSL business as a third. The muni division is nearly out of operation, and DSL lines continue to fall in quantity quarter over quarter. Dial-up is still their cash cow. Helio lost hundreds of millions to obtain just 170,000 subscribers (that number down from 200,000 at the start of 2008). EarthLink will receive a pittance for its investment, part of the $39 million in stock that Virgin will pay for Helio; SK Telecom will invest in Virgin Mobile to obtain a total 17 percent state. Virgin itself makes just a very tiny sliver of profit. MVNOs buy minutes and data from carriers, and Virgin Mobile involves Sprint as a partner, making it the only tolerably successful MVNO.

Can they succeed where EarthLink (and others) failed? Possibly. If they get the same deal that EarthLink previously offered, they're getting a lot of equipment for free and a quantifiable set of problems. I had written earlier it wasn't a good deal for Phila. to accept the network, but a private operator that's locally based and is trying to do good and get a return on its investment may be able to raise money and set more modest goals. Starting from scratch is a non-starter for any firm at this point.

What they desperately need to do if they acquire the network is immediately bulk out several critical square miles, convince the city to buy some service right away (point-to-point dedicated connections to replace wirelines comes to mind, but will an ex-Verizoner be able to convert municipal revenue that's going to his old employer without qualms?), and show that the network can work.

The advertising part is interesting. MetroFi has shown that their particular flavor of ad-supported Wi-Fi doesn't work. But their goal wasn't crossing a digital divide, and the Portland, Ore., network was never given high marks by local users as to its robustness and reach.

Minneapolis suffers the heartbreak of leafage: Leaves are popping in Minneapolis, and Star-Tribune columnist Steve Alexander writes that residents are seeing some Wi-Fi reception problems on that city's Wi-Fi network. This is the only big-city network that can be currently described "successful," even though its long-term success has to be proven out. The firm responsible, USI Wireless, told Alexander they're working on adjusting about 5 percent of antennas to cope with the pesky greenery.

St. Louis Park sues ARINC over Wi-Fi network: The Minnesota town says the network never worked, and had earlier discussed a lawsuit. The city wants the value of the contract ($1.7m) plus a very modest amount in damages and fees ($50,000). The city plans to start removing gear if ARINC doesn't sometime in June. But they have to deal with 490 poles erected to hold the nodes and solar-charging gear--sunk into concrete. More recent testing showed that the network worked well in some areas, but the majority of the network did not, according to the Star Tribune.

Verizon builds out fiber in AT&T territory: Interesting sign of competition in otherwise monopoly-per-provider-type world. Verizon is using AT&T's hard-won statewide video franchising rules in Texas to build competitive fiber in Dallas suburbs. They're apparently not bringing telecom; they're acting like a cable TV firm with data. Verizon owns chunks of territory all over due to it encompassing GTE in a deal years ago. GTE serves suburbs west of Portland, Ore., and east of Seattle, for instance, while Qwest serves most of the rest of each state.

Foster City Wi-Fi dies on June 20: MetroFi is unlighting its cities, and Foster City opted not to spend the nearly $200,000 asking price MetroFi put on its equipment. MetroFi might still find a buyer, but June 20 is the network's current final day. Naperville, Ill., also expects a June 20 shutdown. They, too, were offered the network hardware for 200 grand.

Chehalis lights up: A small city in southern Washington votes to put in Wi-Fi hotzones. The cost is about $53,000 and annual fees $15,000. Funds will come from existing tax and grant sources. The city chose to install service to make sure they're not missing a checkbox on the amenities list for visitors and businesses rather than for a particular, measurable goal.

Nearby Centralia pulls its Wi-Fi: A pilot project in the larger city of Centralia, Wash., a bit north of Chehalis, is shut down when poles used to mount Wi-Fi radios are removed as electrical wires are buried. (The reporter here confuses broadband over powerlines (BPL) with broadband wireless.) The system might be restarted later.

Craig Settles writes up Pennsylvania's Cambria County wireless success: This is a network built for particular municipal purposes, part of Settles's long-time drumbeat about having applications first and then networks built for those networks second. He notes that Cambria built a 700 sq mi network that sounds nearly cost neutral through efficiency and cost conservation--it's cheaper to get much more service with this network than it was for a smaller array of services with incumbent-provided networks.

Santa Fe residents oppose Wi-Fi in the library on health grounds: You know what I have to say about how provable this has turned out to be in clinical studies. I am, however, as always, concerned about these people's health, even if I don't believe that Wi-Fi (or EMF) causes their problems. The group opposed to library-Fi is citing the ADA in this case, uniquely I believe. Six libraries suggested that EMF triggers seizures in epileptics, something I've never heard cited before; maybe CRTs (flickering), but EMF? Wired is substantially less kind than I am, pointing out that EMF other than Wi-Fi produces vastly higher signal strength. (They're sort of ignoring signal strength at a given point where an individual stands in relation to a transmitter, however.)

First, Karl Edwards of Excelsio, a firm that consults on municipal broadband, lays out a pretty straight case as to why EarthLink, Kite, and MetroFi's networks, among other one-offs, were designed to fail. I've written about aspects of this over the last four years, but Edwards is succinct. In part, EarthLink offering to build Philadelphia's network at no cost to the city set the mold wrong for all networks to follow. We're resetting now, and Wi-Fi's moment may have passed.

Edwards offers as one the constraints set by cities, "Expectation that the network would cover 90-95% of the City with wireless coverage as opposed to just in the areas where there was a solid business case." This has been a problem I've had for a couple of years when it started to become clear that 90-plus percent coverage wasn't in the interest of the ISP--nor in the city's interest because these networks couldn't be completed.

Edwards also notes that when consulting for Grand Rapids, Mich., which chose Clearwire as its wireless partner, EarthLink told the city that they expected a conservative 22-percent uptake for their Wi-Fi service by end of the fourth year. Given that in mature markets, a high-single-digit uptake is considered very good, that's shows how the Excel spreadsheets were skewed. USI Wireless's estimates for break-even require less than 10 percent of the population in their covered areas to subscribe, and their numbers of subscribers to date are tracking that number closely.

He closes with a set of eight principles for wireless network builders to come to the table with and cities to adopt, all of which I agree with.

Next, Esme Vos suggests a very modest proposal: San Francisco should have required all its cafes to offer free Wi-Fi, and then Fon or others could have aggregated and bundled access to these locations. There's a long set of comments accusing Esme of communism, socialism, utopianism, and other isms. The post and the comments make for lively reading.

Finally, Craig Plunkett, who operates hotspot networks around New York City and Long Island, chimes in with a summary of these opinions and the notion that muni-Fi jumped the shark when Ocean City, N.J., decided to put Wi-Fi in garbage cans. He points out that "an infill strategy" of providing service where needed and then extending from there is effective.
