ANT overview

The ANT protocol has been engineered for simplicity and efficiency. In operation, this results in ultra-low

power consumption, maximized battery life, a minimal burden on system resources, simpler network

designs and lower implementation costs.

ANT provides carefree handling of the Physical, Data Link, Network, and Transport OSI layers. Please

see Figure 5. on page 13. In addition, it incorporates key, low-level security features that form the founda-

tion for user-defined, sophisticated, network-security implementations. ANT ensures adequate user control

while considerably easing the computational burden, by providing a simple yet effective wireless network-

ing solution.
