"In September, Philadelphia officials announced a $10 million plan to transform all 135 square miles of the city into one Wi-Fi hot spot, placing
cells on street lights and other devices. The service would be free or very low cost, according to the city."
Looks very promising if all goes ahead correctly. The only problem I can see is that what happens when it brakes down? There would be massive chaos as
all the computers in the city on this wireless internet would just be shut off.
