About Nordic ANT wireless connectivity

Nordic ANT chips combine Nordic’s renowned ultra-low power single chip transceivers with ANT RF protocol software for optimized performance with the promise of interoperability

 

Nordic has a long association with ANT (part of Dynastream Innovations) of Canada. This collaboration resulted in the development of the nRF24AP1 ANT chip that has been used in well over five million wireless nodes worldwide. Recently the nRF24AP2 family that includes single- and eight-channel devices, together with an eight-channel version with Full-Speed USB 2.0 compliant interface, has superseded the nRF24AP1.


Nordic ANT chips combine Nordic’s renowned ultra-low power (ULP) single chip transceivers with ANT RF protocol software. ANT is a proven protocol for ULP practical wireless networking applications. Designed for 2.4GHz operation, ANT is suited to any kind of low data-rate sensor network topologies in personal area networks (PANs) and practical wireless sensor networks (WSNs). ANT has been intentionally engineered to simplify wireless network development and maximize network efficiency.

Nordic ANT chips provide the benefits of a power and performance optimized ULP silicon solution with the promise of interoperability with other Nordic ANT-powered wireless products manufactured by members of the ANT+ Alliance. The Alliance ensures standardized communications through optimized brand value and partnerships with other top tier products. Currently, there are over 300 member companies in the ANT+ Alliance, including Nordic Semiconductor.

 

ANT+ facilitates interoperability between manufacturer’s devices and the collection, automatic transfer, and tracking of sensor data for monitoring information anywhere, anytime. The key advantage of this managed network is device specific interoperability that enables wireless communication with other ANT+ products. ANT+ (built on the base ANT protocol) defines device profiles that specify data formats, channel parameters, and network keys.

 

For example, ANT+ has established itself as a de facto standard in wireless performance monitoring in the cycling sector. And ANT+ is not just the choice of casual cyclists and keen amateurs, professional riders in the Tour de France also employ the technology. At the 2010 event, ANT+ wireless sensors monitored the performance of many of the leading riders. Parameters such as heart rate, cadence and power at the bike’s crank were measured and displayed allowing competitors to manage their energy reserves during the race’s grueling stages. In addition, ANT+ formed a critical link in a system that enabled Internet users to track the performance of leading team HTC Columbia’s riders in real time.

 

Nordic ANT chips are also used in many other applications, such as sport, wellness, and home health monitoring.
