Cablevision will ultimately spend about $300m in building a Wi-Fi network exclusively for its customers; 2.4m of these customers qualify to use the service at no cost. There's no pay as you go option, no monthly subscription; you're either a subscriber of theirs, or not. It's a fascinating strategy, because they're leveraging all these dollars as a tool to crack its competitors in the market. With increasing competition from telephone companies that are offering television service, cable companies need to compete on voice, data, and video, as well as well as on mobile offerings. When the network is built, Cablevision can conceivably offer Wi-Fi telephony service, too.

I'm dying to know what the reduced churn rate and increase in subscriptions will be in six months. Given that hotspot access costs $10 to $30 per month depending on the network, Cablevision is delivering something of value. It's great honey for new subscribers and glue to keep current subscribers.

The company is claiming that with this latest activation, they have the largest Wi-Fi network for consumers in the U.S. They're likely correct. The only other public access network of scale that's being used by large numbers is in Minneapolis, and based on what I know about both networks, Cablevision probably deserves bragging rights. The network in Taipei, Taiwan, is likely still larger, but I haven't heard any usage number in nearly two years; at that point, subscription rates were 10 percent of what had been projected.

Four chains, four Wi-Fi pay policies: CIO magazine looks at Borders, McDonald's, Panera, and Starbucks, and how they're offering Wi-Fi. I'd like to suggest you read this article, but the author writes, "Right now, according to Hotspot Locations, there are more than 33,000 WLAN hotspots worldwide, and more than 10,000 in the United States alone." I don't know who "Hotspot Locations" is, and I need to disclose that I have a financial interest in what must be their competitor, JiWire, but any hotspot finder that calls them "WLAN Hotspots" and reports 11,712 in the U.S. and 33,106 worldwide just isn't working very hard. JiWire lists over 230,000 hotspots worldwide, and notes over 60,000 in the U.S., while Boingo and iPass each resell access to over 100,000 hotspots worldwide.

Up, up, and away in my beautiful, my beautiful warballoon: Defcon hackers deployed a balloon with Wi-Fi receivers on it 150 feet in the air to scan for network vulnerabilities in Las Vegas last week. They found 1/3rd of networks had no encryption--although I always wonder if they're using passive scanning where 802.1X allows a limited connection for authentication and appears "open" in some ways, or if they were actively scanning, in which case 802.1X networks would be unavailable.

Cincinnati Metro service has Wi-Fi on 20 buses: The free service supplied by AT&T in an ads-for-access deal with the authority was placed after a couple years of testing on a relatively long commuter run. The authority spends $15,000 per bus to setup a connection, which seems rather pricey. Other authorities are paying in the low thousands, from what I've seen, so I'm not sure what their particular case is.

Boston ferries gain Wi-Fi: The MTBA has put Internet access on its 11 commuter boats that serve 4,500 daily riders. Ridership is way up this year.

Bangkok builds slow Wi-Fi network, free for first year: The details are a bit sketchy, but the government has built a 15,000-hotspot network that offer 64 Kbps connections, and will be free (with an access card) for the first year. The government is handing out 500,000 such cards at shopping malls before this week's launch.

That's an insanely large percentage of riders using the service, so it's possible ridership has increased even more than the mid-May figures indicate, or the commuters are really intense computer and handheld users. Also, note that the FAQ for the authority's overall Wi-Fi service requires you to be 18 years or older. It is Utah, after all--a minor might do something dirty with the service and the transit authority would be held responsible. The authority offers Wi-Fi on some buses, too.

The network is backed by fiber that runs alongside the track, which can make a huge difference in the ability to bring in backhaul. Other train lines have to work with either or both cellular and satellite backhaul, although Nomad typically uses fixed WiMax, as they are in this deployment. They're finishing up a 600 km London to Glasgow route for Virgin in the UK, which will be vastly larger than any other Internet-equipped route in the world.

This is one of the first major production service launches of train-based Wi-Fi in the U.S. VIA Rail in Canada is the only other in-production system offering in-transit Wi-Fi on a train line in North America. There are several trials, pilots, and phased-in plans underway. I thought 2007 would be the year that train-based Internet access took off; looks like it will leave the station worldwide in 2009, perhaps due to better 3G cell cover and improved antenna designs, as well as new commuter rail systems like FrontRunner that are designed with the idea of connectivity.

...a new GPS device enables authorities to remotely control a bus -- slowing it down to 5 mph and preventing it from restarting once it has stopped. The device has been installed on thousands of local commuter and tourist buses.

The technology is designed to prevent a terrorist from ramming a bus filled with people and explosives into buildings or tunnels.

Private bus companies have received millions of dollars from the Department of Homeland Security for the security systems. It costs $1,500 to equip each bus, with $50-per-bus monthly maintenance costs.

Gray Line double-decker tourist buses and Coach USA have spent hundreds of thousands of dollars in federal funds to install 3,000 devices. After receiving a $124,000 federal grant, DeCamp Bus Lines is installing the device on its 80 commuter buses, which travel routes from northern New Jersey to the Port Authority Bus Terminal in Midtown.

New Jersey Transit is currently in the process of equipping all of its roughly 3,000 buses with the technology. NJ Transit Chief of Police Joseph Bober said: "This enhanced technology helps us protect our bus drivers and customers. It's another proactive tool to protect our property, employees and customers."

Microsoft expands its commuter bus system: The Wi-Fi equipped buses will grow to handle 4,600 riders a day from the current 1,800. A good friend will now have a 5-block walk from his Seattle home instead of a sort of impossible bus commute or a tedious daily drive. Microsoft was late to the game of offering free bus service to its employees, and thus their expansion must indicate that the increase in productivity and other goals are being met. The company told the Seattle Post-Intelligencer that 2,500 of the 4,300 employees who have so far used the system for a total of 130,000 rides were single-occupant car drivers.

Nikon's new Coolpix S52c pairs 9 megapixel images, Flickr, Wi-Fi: The $300 camera, shipping in a few weeks, has a 9 MP sensor, 3x optical zoom, and vibration reduction and stabilization. The camera's internal Wi-Fi works with a local network, where it transfers photos to a computer, which then can upload them to their own online service, Picturetown, or it can "email" photos (sending low-resolution images that the companies tend to forgot to give you the specs on how low resolution) at hotspots. The camera comes with six months of T-Mobile service. Pictures can be transferred to Flickr and social-networking sites via a feature at Picturetown.
