5.8GHz and 24GHz all belong to the ISM band. 5.8GHz is the middle-low frequency band, commonly known as the 5G centimeter wave technology

24GHz is a millimeter wave, belonging to the high-frequency

Millimetre wave has a larger bandwidth, as well as faster transmission speeds, millimetre wave can reach a transmission speed of 20Gbit/s, while centimetre wave can not reach. At present, the millimetre wave band is very clean and will not grab space with other signals such as WIFI and Bluetooth. So anti-interference will be stronger.

In smart sensing applications, 5.8GHz and 24GHz are two common radar frequencies, each with distinct advantages:

1. 5.8GHz Radar: Stronger penetration, ideal for complex environments (e.g., through-wall detection), better anti-interference, lower power consumption, but slightly lower accuracy than 24GHz. Commonly used in: 5.8G Motion Sensor , 5.8G Human Presence Sensor, Tuya Zigbee Motion Sensor, Tuya Zigbee Presence Sensor, etc.
2. 24GHz Radar: Higher accuracy, more sensitive to small movements, suitable for precise distance measurement or small-range monitoring, but with weak material penetration. Commonly used in: 24GHz high-sensitivity presence sensor, 24GHz high-sensitivity presence sensor, 24G Sleep Presence Sensor, Tuya Zigbee Motion Sensor, Tuya Zigbee Presence Sensor, etc.

1. Selection Guide:Choose 5.8GHz for wide-area coverage or scenarios requiring penetration (e.g., security systems).
2. Opt for 24GHz when high accuracy is critical (e.g., static presence detection or gesture control).
