ANT+®: A 2.4GHz proprietary wireless networking protocol. One advantage of ANT+ is that it requires very little energy. It is primarily used with sports and fitness sensors, but it can also be incorporated into other sectors, including health, home automation and industry. One of the first applications was actually measuring high-level sports, such as cycling.
