WSJ reporter Lee Gomes does a little war driving and finds we’re [this close] to being meshed–right now.
I set out driving, back and forth, for many long hours. (How do cabbies do it?) While I was only logging technical information about the networks I was encountering, I learned that sometimes, the technical can also be personal. When you set up a home wireless network, you can, if you want, give it a name. Many of the names I was seeing — 2boysNlove, imaginaryfriend, DONTBOTHER — made me feel as though I was eavesdropping on other folks’ somewhat personal affairs.
The undertaking also provided a window into the ways that society and technology intersect. Netstumbler makes a bonging sound every time it detects a network. In Bernal Heights, chock full of Volvo-driving Kerry voters, it was bong-bong-bong, virtually one for every house. My laptop was quieter in the flatlands of the Inner Mission, home to working-class Hispanic families living in three-story apartment buildings. And in the public-housing projects on Justin Drive next to the freeway, it was utterly silent.
In the end, I counted about 3,000 wireless networks in my ZIP Code. The 2003 population of 94110 was 75,000, meaning we have one Wi-Fi access point for every 25 people.
For my project, I had borrowed from my neighbor Brian Warner, a famous programmer in the Python computer language, a small GPS receiver that plugged into my laptop and recorded the locations of all the networks I was seeing. When I was done, I made a map of them. (See map.)
With a lot of help from the folks at ESRI, a mapping-software company, I added to the maps a bit. For instance, I calculated per capita wireless ownership by census tract, and then mapped it. I also mapped average household income. It’s no surprise the two are highly correlated.
In fact, the more affluent parts of my ZIP Code had nearly 10 times as many hot spots, per capita, as less tony areas. It’s the old-fashioned digital divide, updated to the age of wireless.
