…each player will be equipped with a set of RFID sensors about the size of a quarter embedded in his shoulder pads, each emitting unique radio frequencies. Gillette Stadium (and every other stadium used by the NFL) has been equipped with 20 receivers to pick up those radio frequencies and pinpoint every player’s field position, speed, distance traveled and acceleration in real time.
By using two sensors for each player — one embedded in the left shoulder pad and one on the right — the system will also be able to identify the facing of each player.
The NFL plans to use the data generated to power the NFL 2015 app for Xbox One and Windows 10, allowing for things like “Next Gen Replay” that will allow fans to call up stats for each player tied into highlight clips posted on the app. But that’s just the beginning. The data will be fed to broadcasters, leveraged for in-stadium displays and provided to coaching staff and players.
