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. ANT’s protocol stack 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

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.

Incorporated in AP2 product family are several ANT core stack enhancements:

• Background scanning

• Continuous scanning mode

• High density node support

• Improved channel search

• Channel ID management

• Improved transmission power control

• Frequency agility

• Proximity acquisition

The complete description of ANT message protocol is found in the document “ANT Message Protocol and

Usage”. The serial interface details are provided in the document “Interfacing with ANT General Purpose

Chipsets and Modules”. Both documents are available on www.thisisant.com
