What are ANT and ANT+ on Android: just about the complex

ANT (Adaptive Network Topology) is a wireless communication protocol low power consumption, developed by the company Garmin (a well-known manufacturer of GPS navigators and fitness trackers). It allows devices to exchange data over short distances (up to 30 meters) with minimal energy consumption. Technology ANT+ is an extended version of the protocol that supports more types of data and is compatible with a wide range of gadgets.

What are the key features of ANT/ANT+ compared to Bluetooth or Wi-Fi:

• 🔋 Energy efficiency: it consumes several times less battery, than Bluetooth, which is critical for fitness trackers and sensors.
• 🔄 Multichannel: one device (for example, a smartphone) can simultaneously interact with several sensors (heart rate monitor, pedometer, cycling computer).
• 🛡️ Reliability: less susceptible to interference than Bluetooth, especially in conditions of high air congestion (for example, at marathons).
• 📶 Range: up to 30 meters in open space (versus ~10 meters in Bluetooth Classic).

On smartphones Samsung the technology ANT+ is implemented through two components:

1. ANT Radio Service —a system application responsible for the operation of the chip ANT.
2. ANT+ Plugins —a set of modules for interacting with specific types of devices (for example, bicycle sensors or cardio monitors).

It is important to understand that ANT is not only software, but also hardware in smartphones Samsung (for example, in series Galaxy S, Note, A) a special chip is installed, which ensures the operation of the protocol. If your device does not support ANT at the hardware level, then no applications will be able to activate it.
