ANT+ – definition- ANT is a proprietary multicast wireless sensor network technology designed and marketed by ANT Wireless. It is primarily used for sports and fitness sensors. ANT was introduced by Dynastream Innovations in 2003, followed by the low-power standard ANT+ in 2004, before Dynastream was bought by Garmin in 2006.
ANT is a wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks. ANT+ – definition
ANT is an ultra low power protocol that is able to operate off of small batteries, such as coin cells.
ANT peripherals typically operate in a broadcast mode that can be received from multiple handsets or displays simultaneously.
ANT+ (built on the base ANT protocol) defines standardized device profiles that specify data formats, channel parameters and network keys. A “profile” defines a specific use case, or data set. The most common ANT+ profile is heart rate (HR), and is used by many heart rate monitors in the market today.
Other examples of ANT+ profiles include:
Bicycle Speed & Cadence (S&C)
Bicycle Power (PWR)
Weight Scale (WGT)
Blood Pressure (BP)
ANT+, introduced in 2004 as “the first ultra low power wireless standard”, is an interoperability function that can be added to the base ANT protocol. This standardization allows for the networking of nearby ANT+ devices to facilitate the open collection and interpretation of sensor data. For example, ANT+ enabled fitness monitoring devices such as heart rate monitors, pedometers, speed monitors, and weight scales can all work together to assemble and track performance metrics.
ANT+ is designed and maintained by the ANT+ Alliance which is managed by ANT Wireless, a division of Dynastream Innovations owned by Garmin. ANT+ is used in Garmin’s line of fitness monitoring equipment. It is also used by Garmin’s Chirp, a geocaching device, for logging and alerting nearby participants.
ANT+ devices require certification from the ANT+ Alliance to ensure compliance with standard device profiles. Each device profile has an icon which may be used to visually match interoperable devices sharing the same device profiles.
The ANT+ specification is publicly available. At DEF CON 2019, hacker Brad Dixon demonstrated a tool to modify ANT+ data transmitted through USB for cheating in e-cycling
Also, you can have several sensors work with a single receiving display or have several receiving displays read the information from a single sensor. ANT+ – definition
ANT+ ensures trouble-free interoperability, allowing ANT+ products by different makers to work together as long as all paired devices support the same profiles (denoted by teh respective ANT+ activity icons).
ANT+ is already integrated into a lot of mobile phones. The list is probably incomplete and we apologise for that. If you know an ANT+ enabled phone, which has not been marked as such in our database, why not send us a tip?
Here is a list of the ANT+ enabled phones in our specifications database.
