ANT™ Overview
ANT™ is a practical wireless sensor network protocol running on 2.4 GHz ISM band. Designed for ultra low power,
ease of use, efficiency and scalability, ANT easily handles peer-to-peer, star, tree and practical mesh topologies.
ANT provides reliable data communications, flexible and adaptive network operation and cross-talk immunity. The
protocol stack of ANT is extremely compact, requiring minimal microcontroller resources and considerably reducing
system costs.
ANT provides carefree handling of the Physical, Network, and Transport OSI layers. In addition, it incorporates key
low-level security features that form the foundation for user-defined, sophisticated, network-security
implementations. ANT ensures adequate user control while considerably lightening computational burden in
providing a simple yet effective wireless networking solution.

ANT supports public, managed and private network architectures with 2
32
uniquely addressable devices possible,
ensuring that each device can be uniquely identified from each other in the same network.
ANT is proven with an installed base of over four million nodes in ultra low power sensor network applications in
sport, fitness, home and industrial automation. The ANT solutions are available in chips, chipsets and modules to
suit a wide variety of application needs.
Enhancements in this new generation ANT core stack:
Advanced burst data transfer up to 60 kbps (true data throughput)
Single channel encryption
Up to 8 ANT network keys
High duty search and active search sharing
Event buffer and filter
Fast channel initiation
Asynchronous transmission channel
Selective data updates

ANT+ and ANT+ Alliance
ANT+ is the open application layer on the top of the ANT stack. It standardizes communications and facilitates
interoperability between a wide array of personal sports, wellness and lifestyle monitoring devices. ANT+ defines
device profiles that specify access, data formats, and channel parameters.
