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.

Physical Layer

ANT supports public, managed and private network architectures with 2 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.

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

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.

The ANT+ Alliance is comprised of companies who have adopted the ANT+ promise of interoperability. The Alliance ensures standardized communication through optimized brand value and partnerships with other top tier companies and products.

ANT C7 RF Transceiver Module Page 5 of 20

1. ANT C7 Module

The ANT C7 module is a drop-in module using CC2571, an ANT network processor from Texas Instruments. The chip is able to support up to 8 independent ANT channels and for the first time offers the following features embedded:

 ANT File Share (ANT-FS)  AES-128 data encryption  Maximum +4dBm transmission power  High resolution RSSI reading

An F PCB antenna being integrated on the small-sized 20mm by 20mm board, the module has been certified to comply with radio regulation or standards covering global markets include North America, Europe, Australia and New Zealand.

The ANT C7 module eases the burden for application and system developers from extensive RF design and regulatory compliance testing, allowing quicker time to market. The module is ideal to build control or hub nodes of a wireless sensor network.

Incorporated in C782MxIB module product family are several new generation 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

C782MxIB module is good for chip evaluation of both CC2570 and CC2571 from Texas Instruments.

C7 modules are currently available in the following varieties.
