ANT

Adaptive ultra-low power wireless that’s exceptionally easy to use


The ANT Advantage

Flexible and simple to use

Good choice for small, battery-operated devices

ANT is a popular proprietary ultra-low power wireless solution operating in the 2.4GHz ISM band that is especially suited for battery operated products. Its outstanding power efficiency has seen it become a popular choice for wireless applications in the fields of sports and fitness, and health and wellness.

Lightweight protocol with interoperability
The easy to use lightweight protocol helps developers make and implement wireless products with a small memory footprint. The ANT+ managed network gives vendors product interoperability, including a broad set of application-specific profiles allowing products to exchange data and work together. A number of Android devices have native ANT support.

ANT resources include:

  • ANT network processor and SoCs
  • ANT+ Application-specific ICs
  • ANT and ANT/Bluetooth protocol stacks
  • ANT modules and USB dongles
  • ANT development kits
