Pervasive WiFi

This is a list of all the Wifi signals iStumbler on my MacBook picked up at the Brasil Coffee Shop at the corner of 30th Street and Lexington Avenue in Manhattan at 7:15 p.m. Friday, June 9, 2006. There are 53. (Click for a readable image.)

This suggests a number of ideas:

Wireless devices are pervasive.

A planned network might be more efficient, especially given the number of devices using the same frequency.

The number of secured networks is surprisingly large/small (depending on your perspective). (A number that look open—that have the green symbol next to them—are in fact regulated by MAC address or, as in the case of GoldenTree, by user/password authentication via a web page). I am, in fact, posting this using an open network.

The number of opportunities for Wifi abuse in Manhattan are greater than zero.

The 2002 Manhattan wardriving map needs to be redone.

A warflying map of Manhattan needs to be done: what would that list look like five stories up? Twenty?
