Last year the NFL brought in Extreme Networks as its official Wi-Fi analytics provider and tested in-stadium Wi-Fi at Super Bowl XLVIII. Now that the league has some testing under its belt, it's applying some lessons learned for the 2014 season. "We really learned that you can’t just roll out Wi-Fi without a really strong DAS and vice versa," says NFL CIO, Michelle McKenna-Doyle. She says analytics from the Wi-Fi network allow teams to identify and fix problems with the connectivity, such as microwaves at a hot dog stand that could disrupt the network, and add additional hot spots if necessary. "The only way to nip it in the bud is to have real-time analytics," she says.
