If you are lucky enough to be at the 2014 World Cup in Brazil, chances are you will have access to the public WiFi networks set up just for the event. At least half of the 12 World Cup stadiums will have public WiFi available, with over 2,300 access points.
This includes inside the stadiums as well as the areas close by, such as parks, public transit stations, and squares. So that means that not only will those inside the stadium have access to public WiFi, but many thousands of other soccer fans outside as well.
Unfortunately, the World Cup (and its public WiFi) is attracting more than just soccer fans.
