Also complicating Kraft's 2015 goal is the lack of league consensus about who will build Wi-Fi networks in all of its stadiums, and when.
By contrast, Major League Baseball named wireless-tech company Qualcomm its official technology partner in April, launching a two-year study to solve mobile-connectivity issues in its 30 stadiums. Kapustka said MLB was in a position to strike the overarching deal with Qualcomm because team owners made the league responsible for digital properties during the 1990s.
The NFL has a variety of rights deals, including Direct TV and Verizon, which make it more difficult for the league to agree on a single Wi-Fi plan, he said.
"My opinion is they (the NFL) will eventually have something more like MLB," Kapustka said. "MLB has shown it is a great way to make money."
