Newspaper writers are trained to always include an opposing viewpoint in their stories. Supposedly this makes the article "objective". It's really amusing to me sometimes how that plays out as writers scramble to find controversy on a tight deadline for a relatively non-controversial story.

That quote is kind of the "standard controversy" that reporters bring up about our project. No matter how many times we tell them that we're only sharing business class DSL lines which don't have sharing restrictions and that any city-wide implementation would share bulk-rate T1 or T3 bandwidth that is definitely sharable.

The more interesting controversy is that if we're really wildly successful we'll make DSL irrelevent as our network will be a more efficient last mile solution for delivering bulk purchased bandwidth to urban consumers. Of course, we might also completely fail. This is brand new stuff.

Have you heard any rumblings on how they (ISPs) plan to compete with you if this happens?

If we're successful I suspect that there'll be some issues, some regulatory struggles, but ultimately I suspect the ISPs will be glad that they don't have to support the unprofitable last mile anymore. Selling bulk bandwidth for the long haul, providing cross town wired links to join together distant parts of the wireless network, and providing server infrasructure are all far more profitable activities for ISPs than providing DSL or cable modems.

My guess actually is that you're going to run out of spectrum and/or start angering homeowners by interfering with their own home wireless networks as this gets to be too successful. You're still using off-the shelf 11b stuff, no?

Yah we're using off the shelf 11b stuff now. We're aware that there's going to be some political fights neccessary to get some more spectrum available to the general public for this stuff. We're working behind the scenes with a lot of folks to make sure that projects like ours are considered in the ongoing public interest political battle over spectrum. We're seen as a model argument for why the public should be given access to more spectrum for flexible open applications.

One thing we have going for us is that by using high gain omnis at rooftop level there is actually a radio shadow below the antenna so that a lot less energy goes into the home of someone with a node than gets to the rooftop of someone's neighbor.

We're also looking into a number of ways to minimize our use of spectrum via variable power radios (adjust transmit power based on the packet destination) and "smart antenna arrays" (so that we have omni-directional coverage but any given packet is actually transmitted as a directional beam to it's destination). Those are both a ways off. The radios that would facilitate both of these ideas are currently not open spec so we can't write drivers to their full capabilities.
