What is ANT?

About ANT

ANT is a proprietary wireless sensor network protocol, which is running in 2.4 GHz band. This protocol is
developed by Dynastream Innovations Inc., a subsidiary of Garmin Ltd. ANT can work at ultra-low power
consumption and is capable of handling various types of topologies such as peer-to-peer, star, and fixed
mesh topologies. However, the communication distance is limited, and the amount of data that ANT can
transmit at one time, is also restricted.

About ANT+

ANT+ is a managed network based upon ANT technology. This managed network provides “device profiles,”
which allow the same profiles of ANT devices to communicate each other. To grant the communications,
ANT+ presets the values of parameters for each profile. The types of profiles are heart rate monitor, pedometer,
scaler, cadence sensor and other fitness and wellness devices. Totally 15 ANT+ profiles are available.

FAQ

Q: Can ANT devices directly communicate with ANT+ devices?
A: No, ANT device cannot directly communicate with ANT+ devices. ANT+ uses ANT protocol, but ANT devices cannot use “ANT+ Network Key,” “ANT+ Device Profiles,” which are necessary for the communication between ANT+ devices. Moreover, ANT devices are not allowed to use a 2457MHz frequency, which is designated for ANT+ devices. Therefore, ANT and ANT+ devices cannot communicate each other.

Q: Can ANT+ devices use ANT/BCA_Lib?
A: No, they cannot. BCA_Lib is specifically designed for ANT devices.

Q: Please tell me how to obtain “ANT+ Network Key” and/or “ANT+ Device Profiles.”
A: Please register “ANT+ Adapter Account” from this page. Its registration is free for all. (This site runs by Dynastream Innovations Inc, which is the creator and developer of ANT/ANT+.

After the registration is completed, please go to ANT+ Basics and find the section of “How do I obtain the ANT+ Network Key?” If you agree to the terns of use and access the ANT+ Network key, please click “Agree to the terms of use and access the ANT+ Network Key.” Then, you will find “ANT+ Network Key” and other information in the liked page.

ANT Hardware

ANT Adapter

ANT Adapter is an ANT-30pin adapter for iPhone and iPod touch, which are equipped with 30pin connector and internal GPS.
ANT Adapter supports ANT protocol as well as ANT device profiles. To communicate ANT+ sensors, ANT Adapter requires
the specific iOS application, BeatRun.
This adapter has passed the certification test of Apple MFi Program, and it has been received Technical Conformity form
the Japanese regulatory authority.

For the details of ANT Adapter, please visit ANT/ANT Adapter.

Also the farther information of BeatRun is available at ANT/BeatRun.
