The panel will discuss fourth-generation (4G) networks, including both LTE and WiMax, and discuss what these networks might deliver, as well as how Wi-Fi networks fit into this future.

One of the organizers asked if I'd solicit questions--you can post them below--which they'll try to ask during the panel. The group would then write up responses which could posted in turn here.

The powerhouse that is Kevin Werbach, a professor at The Wharton School, is moderating the event. Werbach has been part of interesting thinking about spectrum for many years, a former editor of Release 1.0, and a former FCC staffer. He'll share the stage with a fairly high-powered crowd, including AT&T's enterprise architect for mobility, the president of NAC, and senior people from Comcast and Sprint Xohm.

The event is part of the Mid-Atlantic Chapter series called MobileMonday, an interesting business group that's trying to provoke discussion and development around mobile technology and access. This particular event is sponsored by local business development organization Select Greater Philadelphia.

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.

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.

Three other significant details appear in the release, as well: The network will be free (that was discussed but wasn't entirely clear before), and may includes advertising, sponsorships, and other programs; the network will be focused on outdoor applications, not indoor service, hurray; and there will be no customer support--this will be a best-effort network that you can't complain about when it doesn't work.

So far, promising.

What do you get with that $17m network? A lot of heartache, but also a new business model that just might work. I discuss the new plan in Philadelphia in this audio mobile post.

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.

GigaOm's Michael Wolf rounds up what other forms of networks are needed in a home beyond Wi-Fi: Ethernet, HomePlug, MoCA, HomePNA, Wireless HD, personal networks (Bluetooth), and automation controls. (My home is a very stupid home, thank you very much.)

He who steals my Wi-Fi steals hash: Mike Rogoway at the (Portland) Oregonian poses the question as to whether using a neighbor's unsecured Wi-Fi is borrowing, stealing, or nothing at all. I pipe in noting that more people are securing their networks. In my current office, where I've been three years, I spotted over a dozen networks when I arrived, most unsecured. Today, all the networks are secured (only some are small business networks), and many of the names have changed. The reasons? Better security wizards, widespread use of WPA, improved Wi-Fi network setup in Windows Vista and XP SP2, start of use of WPS, and general fear of security issues. Rogoway also runs through what the options for connectivity in Portland are as MetroFi is about to hit its network shutdown date.

Philadelphia's mixed free airport Wi-Fi: I somehow missed this story months ago, but PHL (Philadelphia's airport) is offering free Wi-Fi on the weekends to every one, and free Wi-Fi on the weekdays to college students. Students go to an information counter, show their valid student ID, and get an access code. This is a very neat idea. The airport is otherwise $8 for 24 hours or $40 per month, although it's part of much cheaper roaming plans from Boingo Wireless and iPass.
