National Football League venues are struggling to catch up with technology advancements in home viewing, and despite NFL commissioner Roger Goodell's pledge in May 2012 to equip all 31 NFL stadiums with Wi-Fi, less than half are currently Wi-Fi-enabled and no venues have deployed new systems this year. The delay is partly rooted in some stadium operators waiting for next-generation Wi-Fi speed upgrades before installing networks, reports Mobile Sports Report editor Paul Kapustka. Another hindrance is the fact that venue owners and operators must cover the installation costs out of their own pockets. The NFL's Brian Lafemina says the league is still seeking a telecom partner that can help resolve issues of venue location, design, and the multitudes of fans all trying to simultaneously access the network. This year the NFL is introducing numerous tech enhancements at stadiums, such as locker room cameras, video boards that will show replays of every play, and free access to the league's NFL Red Zone cable channel for season ticket holders. The NFL's Jonathan Kraft previously has said that he expects to have all stadiums Wi-Fi-enabled in time for the 2015 season. Kapustka stresses that "stadium owners and operators need to get their hands on the fact that they need to put in Wi-Fi like they need to put in plumbing."
