Nike+ has long been referred to as the quintessential example of a personal area network (PAN) product. A sensor in the user’s Nike shoe wirelessly interacts with the user’s iPod, iPhone or Nike SportsBand. The Nike+ system tracks elapsed time of the workout, the distance traveled, pace and calories burned, and heart rate thanks to a collaboration with Polar.
Nike+ also offers a smartphones app that does not require the companion sensor: Nike+ GPS. The app uses the smartphones GPS and accelerometer to track distance and movements.
