Question

Z-Wave operates at a frequency of 908.42 MHz in the US (and other frequencies elsewhere, none of which are 2.4 GHz), which avoids interference with devices that use the 2.4 GHz band. Additionally, Z-Wave devices can communicate over distances up to 100 meters in open air, which meets the requirement of being at least 50 meters away from the base station. Zigbee, Bluetooth, and NFC all primarily operate in the 2.4 GHz frequency band, which could lead to potential interference with other devices in that band. NFC is also designed for very short distances, typically a few centimeters, far below the required 50 meters.
