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 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

AP2 RF Transceiver Module 5 of 19

1 ANT AP2 Module

The ANT AP2 module is a drop-in module based on the reference design of nRF24AP2, a new generation of ANT system on chip family from Nordic Semiconductor. An F antenna is 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, Japan and Australia. The integrated module eases the burden for application and system developers from extensive RF and antenna design, and regulatory compliance testing, allowing quicker time to market. Able to support 8 ANT channels, the module is ideal to build control or hub nodes of a wireless sensor network.

AP2 modules are currently available in the following varieties.
