Tom Pelissero talks about the new system which will be installed at 17 NFL stadiums this season:
The NFL partnered with Zebra Technologies, which is applying the same radio-frequency identification (RFID) technology that it has used the past 15 years to monitor everything from supplies on automotive assembly lines to dairy cows’ milk production.
Work is underway to install receivers in 17 NFL stadiums, each connected with cables to a hub and server that logs players’ locations in real time. In less than a second, the server can spit out data that can be enhanced graphically for TV broadcasts with the press of a button.
TV networks have experimented in recent years with route maps and other visual enhancements of players’ movements. But league-wide deployment of the sensors and all the data they produce could be the most significant innovation since the yellow first-down line.
The data also will go to the NFL “cloud,” where it can be turned around in seconds for in-stadium use and, eventually, a variety of apps and other visual and second-screen experiences. Producing a set of proprietary statistics on players and teams is another goal, Shah said.
NFL teams — many already using GPS technology to track players’ movements, workload and efficiency in practice — won’t have access to the in-game information in 2014 because of competitive considerations while the league measures the sustainability and integrity of the data.
“But as you imagine, longer-term, that is the vision,” Shah said. “Ultimately, we’re going to have a whole bunch of location-based data that’s coming out of live-game environment, and we want teams to be able to marry that up to what they’re doing in practice facilities themselves.”
Zebra’s sensors are oblong, less than the circumference of a quarter and installed under the top cup of the shoulder pad, Stelfox said. They blink with a signal 25 times a second and run on a watch battery. The San Francisco 49ers and Detroit Lions and their opponents wore them for each of the two teams home games in last season as part of a trial run.
About 20 receivers will be placed around the bands between the upper and lower decks of the 17 stadiums that were selected for use this year. They’ll provide a cross-section of environments and make sure the technology is operational across competitive settings before full deployment.
