ANT+ vs. Zigbee
Comparing 2 standards across 13 specifications. 13 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.
Zigbee is an open global wireless mesh networking standard maintained by the Connectivity Standards Alliance (CSA), based on IEEE 802.15.4. Operating primarily in the 2.4 GHz band at 250 kbps, it uses self-healing Ad-hoc On-Demand Distance Vector (AODV) routing to connect up to 65,000 nodes in smart lighting and home automation.
