From Neal Peirce's latest column:
"Philadelphia is debating making all 134 square miles of the city the world's largest wireless hotspot. Boston, Atlanta, New York, Los Angeles and other cities are considering parallel moves. In Europe, the firm HotSpot Amsterdam is set to go citywide in the Dutch capital soon."
The world's largest WiFi HotSpot is in Washington state dwarfing any of the proposed city-wide proposals. The only thing is that it's not free.
Yes, as written about rather extensively here
