This featured article gets into the nitty gritty of WiFi and Cellular connections at sports stadiums around the country. Stadiums are working to keep cell phones online and WiFi available, but they might not be able to keep up with the demand. Gillette stadium offers an app to those in premium seats that gives streaming video from multiple camera angles of the on-field action and access to NFL Red Zone. The SF Giants have a "race" that is powered by fans shaking their phones (??). There's also plenty of technical information for geeks who are interested.
As more people live-tweet/blog games, and legends like #SonarFeed are born, will data prove to be a great compliment to the on-field action, or will it be a great distraction?
