Football coaches at every level have long relied on game film to judge their teams’ performance. But this year, NFL teams have partnered with Zebra Technologies to more accurately track their players’ position and speed on the field.
The real-time location solution (RLTS) used by the NFL relies on radio frequency identification (RFID) tags worn by the players in their shoulder pads. Each RFID tag broadcasts its location 25 times per second to the approximately 20 receivers located around the stadium. From this single sensor, the MotionWorks server can determine a player’s location on the field and speed. By adding a second sensor, Zebra can also track a player’s direction and orientation. The sensors, placed on the player’s shoulder pads, are less than an inch in diameter, and include a battery designed to last an entire season. This improves the usability and scalability of the solution, since teams won’t need to spend time and energy removing, charging, and reinstalling the sensors.
