GENERAL DESCRIPTION
Ultra low power wireless sensor networks
Embedded ANT protocol
The 1-channel nRF24AP2 includes a fully embedded, enhanced ANT protocol stack. It is designed for ULP operation, ease of use, efficiency and scalability. ANT provides a full communication stack implementation equivalent to Physical, Network and Transport OSI layers. It offers reliable data communication, flexible and adaptive network operation and interference immunity.
Advanced network topologies
While the 1-channel nRF24AP2 supports only 1-channel, it can easily participate in a wide range of different network topologies with other ANT-enabled devices - including peer-to-peer, star, tree and practical mesh.
Communication modes and message intervals
The 1-channel nRF24AP2 provides three different communication modes:
Broadcast
Acknowledged
Burst
Broadcast is a one-way, node-to-node communication where the receiving node provides no acknowledgment. This mode is ideal for applications where newest data is of more importance than the occasional loss of data. In Acknowledged messaging mode the receiver sends an acknowledgement of received data. This mode is ideal for applications requiring 100% data integrity. Burst mode meets the requirements of applications requiring higher data throughput. It provides up to 20kbps acknowledged data transmission.
The 1-channel nRF24AP2 provides programmable message rates from 0.5 to 200Hz.
Enhanced ANT core implementation
New features, lower power and higher performance
The 1-channel nRF24AP2 includes an enhanced ANT core stack implementation offering new features, lower power and improved performance compared to the previous generation solution - the nRF24AP1. The most important new features are: Scanning channel to support lower latency; High density node support for up to 80 nodes in close proximity; Improved channel search that has less impact on active channels; Channel ID management that offers improved pairing efficiency; Improved transmission power control offering TX power control on a per channel basis; and a Frequency agility mode that improves co-existence performance in noisy RF environments.
Multivendor interoperability
1-channel nRF24AP2 is ANT+ ready
The 1-channel nRF24AP2 is fully ANT+ compatible. ANT+ is a set of device profiles and technology specified by the ANT+ Alliance that sits on top of the ANT core stack. The device profiles specify data formats, channel parameters and network keys enabling vendors to make products that are interoperable with products from other vendors. With millions of systems already shipped, ANT+ is becoming a de-facto standard for ultra low power (ULP) wireless. For a complete listing of device profiles and more information about the ANT+ Alliance and ANT+ technology please visit: www.thisisant.com.
