RFID CASE STUDY
People love sports statistics and the more the better. Responding to this customer demand, the NFL increased the quality and quantity of statistics available tocoaches and fans with radio frequency identification (RFID) chips.
Player RFID Project
When the 2015 National Football League played its first game in New England, each player was equipped with a set of RFID sensors. Each sensor, about thesize of a quarter, is embedded in players' shoulder pads and remits a unique radio frequency. Every stadium used by the NFL is equipped with 20 receivers topick up the RFID signals and pinpoint every player on the field. It also records speed, distance traveled, acceleration in real time, and the direction the playeris facing.
The NFL plans to use the data it collects to power an Xbox One and Windows NFL apps to allow fans to call up stats for each player tied into the highlight clipsposted on the app. The data will also be fed to broadcasters, leveraged for in-stadium displays, and provided to coaching staff and players.
"We've always had these traditional NFL stats," says Matt Swensson, senior director of Emerging Products and Technology at the NFL. "The league has beenvery interested in trying to broaden that and bring new statistics to the fans. Along the way, there's been more realization about how the data can be leveragedto make workflow more efficient around the game."
Zebra Technologies Software Vendor
The NFL's technology partner in its IoT push was Zebra Technologies of Lincolnshire, Illinois.
Zebra was well known for its manufacturing and selling, marking, tracking, and printing technologies such as thermal barcode label and receipt printers, RFIDsmart label printer/encoders, and card and kiosk printers. As it moved into IoT and M2M applications, Zebra launched its MotionWorks Sports Solution, whichpowers the NFL IoT initiative. Zebra was able to develop RFID tags that blink up to 85 times per second to track motion of athletes in subseconds. Then it hadto find a customer for the product-so it turned to the biggest fish in the pond-the NFL. Zebra trialed the tags by equipping more than 2,000 players, 18 NFLstadiums and officials, markers, and pylons. Over the course of the season, more than 1.7 billion sets of XY player coordinates were measured, transmitted,and stored during the games. Every stadium was connected to a command station in San Jose, California, that controls when the data are collected, wherethey are sent, and stores them in the cloud.
The Need for the Right People
An important lesson that Zebra learned is that generic data scientists weren't sufficient to gain insight into the data. Zebra needed football experts. "When youlook at analytics in football, you really need people. We had to go out and hire football people. The analytics from manufacturing weren't the same as theanalytics from football. We could see correlations in the data that seemed important and then found out they weren't. We had to bring in people that had thefootball expertise who could say, 'Look, this is why it matters'," said Jill Stelfox, Zebra Technologies Vice President and General Manager, Location Solutions.
The latest development in this IoT initiative is its integration with NFL's fantasy football offerings.
