Mike Mennonno finds himself in a WiFi pickle: His downstairs neighbor suddenly added encryption to her wireless network and he can't use the BPL wireless because of that matter of the outstanding library fines, which means he can't get a library card for the PIN he'd need to use their network:

... So I was stuck. It's Karma, of course. I could tell you the whole story of the card, the books, the fine, but it's very long, and very, very sordid. ...

BART, San Francisco's subway system, is looking for vendors to WiFi-enable its trains.

What if the T did that? Of course, this being Boston, you'd probably wind up with doofuses taking up three seats for their laptops and venti grandes - or whacking people in the head as they try to angle their Treos for maximum download speeds.

Boston Unplugged: Mapping a Wireless Future, released today by the Boston Foundation, the Museum of Science and West Roxbury/Jamaica Plain City Councilor John Tobin, explains why they think Boston needs a citywide wireless network:

Boston is known around the world for its innovation. Our technology, education, and healthcare institutions are recognized all over the globe. Our city attracts some of the brightest minds and talented professionals in a wide variety of fields. If Boston wants to maintain that edge it must keep pace with
the changing world.

Ah, the old world-class city gambit! Kevin Rothstein expresses some skepticism:

WiFi took a major step forward today ….. haven't we heard this before? ...

While Boston struggles to build wireless coverage in a select number of neighborhood commercial districts, MIT and Cambridge are looking at blanketing the entire city of Cambridge with WiFi by the end of the year:

... The initial testing phase and service will be provided by MIT free of charge to Cambridge, Kurt L. Keville '90, a research specialist at the Institute for Soldier Nanotechnologies at MIT, said in an e-mail. But if MIT has underestimated the traffic on the network, the service will have a charge rather than being free; however, Keville said he does not anticipate any problems because MIT's bandwidth is "ridiculously high." Cambridge has over 100,000 residents. ...

They'll be using Roofnet "mesh" technology, developed at MIT, that reduces the costs of the network by turning each participant into a router, reducing the number of dedicated routers needed. A Roofnet is also being built at the South End's Tent City.

Note: To be fair, in addition to the Boston Main Street program, every Boston Public Library branch offers free WiFI.

... They are focusing first on housing development, so we might get early access since we are near the Putnam projects (and that’s a good thing for once!). ...

David discusses a project in Cedar Rapids, Iowa, in which transit buses become part of a wireless mesh - that lets riders get on the 'Net at T-1 speeds and which aims to make the buses more secure (drivers have panic buttons and cameras that, once the button is pressed, can be controlled remotely by police):

... I find it incredible that while Boston, known for good reason as the Hub of the Universe (and points beyond), is still yammering about whether to create a muni mesh network, the good folks of Cedar Rapids are already demonstrating every day that this kind of system pays both security AND economic benefits (in part, it was undertaken as part of an urban revitalization scheme, and to give transit riders a few perks -- that would sure get me out of my car!). Let's get with the program, Boston. ...

The more cynical among you no doubt would suggest the T would be far more interested in using CharlieTickets to track users than providing a new, useful service (is my mind going, or did the T once promise to bring cell service to underground stations?). But the T might also take another lesson from Cedar Rapids, specifically, its passenger hygiene policy:

Personal hygiene must be maintained in a manner that does not result in offensive odors that are unavoidable and objectionable to other passengers.

Steve does a video report on the Globe's Pulse Points - wicked-fast Web sites that blast information at your wireless-enabled laptop - but only if you're within range of one of their access points (currently South Station and Trident Booksellers and Cafe on Newbury Street).

Nope, no involvement with this for this Globe correspondent.

If it's true, it's a helluva value, somewhere near the intersection of Mass. Ave. and Boylston St.

WiFi signals may not travel well past the front of stores. Main Streets hopes to encourage business owners to get the signal deeper into their buildings via discounted packages consisting of a Colubris repeater, installation and a decal that let's shopowners let the public know they offer free Wi-Fi. The equipment will cost about $300, installation about $45, although the first storeowners to sign up will get free installation.

The goal of the WiFi program is not to compete with ISPs but instead give business owners in each of the city's 19 Main Street commercial districts an new tool for attracting customers.

You got signal? I got signal! Brian Goodman of Boston Main Streets and Pat McCormick of the Boston Wireless Advocacy Group check out Roslindale WiFi under the stars - just like Hyde Park WiFi, only Rozzier - after a meeting about WiFi in Roslindale, Hyde Park and West Roxbury.

Hyde Park's become the second city neighborhood to get a city-sponsored WiFi zone after Roslindale. The city's Main Streets program last week installed a wireless access point atop the municipal building in Hyde Park (at Fairmount Avenue and River Street) - similar to the wireless access points that now cover Roslindale Square.

The service, separate from the Boston Public Library's existing WiFi service at the Hyde Park branch, is aimed at giving local businesses a way to give their employees and customers quick 'Net access. But anybody within sight of the municipal building can tap in.

John isn't buying Massport's contention that it had to shut down free Wi-Fi competitors to its paid service at Logan for public-safety reasons:

... Critical public safety communications? This is about homeland security? Please. They must think we're idiots.
