ANT+ vs. Z-Wave
Comparing 2 standards across 12 specifications. 12 key differences identified.
ANT+ is an ultra-low power 2.4 GHz wireless sensor networking protocol managed by the ANT Wireless alliance (a subsidiary of Garmin). Designed for deterministic, multi-channel sports and health sensor telemetry, it enables heart rate monitors, power meters, speed/cadence sensors, and smart bike trainers to broadcast metrics simultaneously to multiple head units and watches.
Z-Wave is a proprietary wireless mesh communications standard standardized by ITU-T G.9959 and governed by the Z-Wave Alliance. Operating in unlicensed sub-gigahertz frequency bands (868.4 MHz in Europe, 908.4 MHz in the US), it eliminates interference from 2.4 GHz Wi-Fi and Bluetooth, supporting up to 232 mesh nodes (and up to 4,000 nodes in Z-Wave Long Range).
