Bluetooth Smart enables even the smallest wearable products such as foot pods to operate for years on a battery the size of a coin cell.
Bluetooth Smart is the able to communicate with mobile platforms including Apple iOs, Google Android, Microsoft Windows 8 and the BlackBerry operating system.
Moreover, the dongle-free connectivity of Bluetooth Smart gives it an edge over other rivals.
One wireless technology specifically designed for the health and fitness market and popular with heart-rate monitors, ANT/ANT+, is a low-power technology that, however, does not enjoy the same broad support in mobile platforms.
A PC or dongle is required for ANT/ANT+, unlike Bluetooth Smart. Still, ANT/ANT+ enjoys a significant market share and seems to have a defensible position, especially in products designed for serious fitness enthusiasts and in cycling electronics.
