From Kevin Werbach: “Marcos R. Lara of the Public
Internet Project has unveiled an amazing map of WiFi
access points in Manhattan, compiled by volunteers who drove along every street.
As you’ll see, virtually all of the island is covered.”

DATA STATS: 1) ~13,000 unique nodes
2) 60% open to public access
3) Approx. 1,000,000 data points collected

That’s one big-ass neighborhood WAN!
