34023 - What is the difference between ANT and ANT+?

ANT™: The Protocol

ANT is a proven ultra-low-power (ULP) wireless protocol responsible for transmitting information wirelessly from one device to another in a robust and flexible manner.

With millions of deployed nodes, ANT™ seamlessly adapts to any type of low-data-rate sensor network topology, ranging from peer-to-peer or star configurations to practical mesh setups, in personal area networks (PANs). It is highly suitable for sports, fitness, wellness, and home health applications. Additionally, ANT is a practical solution for home local area networks (LANs) and industrial automation applications.

ANT is a practical 2.4 GHz wireless network protocol and integrated system solution specifically designed for wireless sensor networks (WSNs) that require...

  • Ultra-low power consumption: operates on a button cell battery for years
  • Resource optimization: fits into a compact-sized memory
  • Network flexibility and scalability - self-adaptable and capable of practical mesh configurations
  • User-friendly with low system cost - operates independently with a single chip

ANT devices can use any radio frequency from 2400MHz to 2524MHz, except for 2457MHz, which is reserved for ANT+ devices. Similarly, ANT devices can utilize the public network key, a private network key, or a privately-owned managed network key, but they cannot use the ANT+ network key, as it is also reserved for ANT+ devices.

ANT+: Open Interoperability

ANT+ is a set of mutually agreed-upon definitions regarding the information sent via ANT. These definitions are called device profiles and are typically linked to a specific use case. For instance, a heart rate monitor will transmit information about your heart rate, as defined in the ANT+ device profile for a heart rate monitor. These device profiles are shared among all ANT+ Adopters, allowing any ANT+ Adopter to create a heart rate monitor or a heart rate monitor receiver that interoperates seamlessly. When a device bears the ANT+ logo, it signifies that it has been certified to be interoperable with other ANT+ branded devices.

Since ANT+ is based on the ultra-low-power ANT protocol, the network is optimized for consumption, cost, latency, communication robustness, and ease of implementation.
