With the continuous advancement of technology, intelligent sensing technologies are being increasingly applied across various fields. In public spaces—particularly in specialized environments such as third‑party restrooms—the demand for safety, convenience, and privacy protection is steadily growing. As an advanced sensing technology, millimeter‑wave radar, owing to its unique advantages, holds significant potential for use in third‑party restrooms. This paper aims to explore the feasibility of deploying millimeter‑wave radar in such settings and to analyze the benefits it can deliver.

 

I. Overview of Millimeter-Wave Radar Technology

Millimeter-wave radar is a radar system that uses millimeter waves for range, velocity, and angle measurement. Due to its short wavelength, it can achieve high‑precision target detection within a compact footprint and is less susceptible to interference from visible‑light and infrared sources. Moreover, millimeter‑wave radar offers strong penetration, robust anti‑interference performance, and excellent reflection from metallic objects, making it highly promising for a wide range of applications.

Next, we will compare the advantages of a 60 GHz millimeter-wave radar with those of other radars, including PIR radar, 2.4 GHz radar, 5.8 GHz radar, and 24 GHz radar.

Among these, millimeter-wave radar–based fall detection plays a crucial role in the third restroom.

What is millimeter-wave radar-based fall detection?

Millimeter-wave radar–based fall detection is a technology that leverages millimeter-wave radar to detect falls. A millimeter-wave radar–based wireless human‑presence alarm device emits and receives millimeter-wave signals to sense and monitor the surrounding environment. When a person enters the sensing range and experiences a fall, the device promptly captures the corresponding signals, analyzes and processes them using algorithms, and ultimately triggers an alert.

For third‑party restrooms—typically accessible toilets designed to accommodate individuals with special physical needs, such as people with disabilities or older adults—millimeter‑wave radar–based fall detection can serve the following purposes:

1. Real-time monitoring and early warning: The millimeter-wave radar-based fall detection system can continuously monitor the activity of individuals in the restroom; upon detecting a fall, it immediately triggers an alarm. This enables prompt identification and response to fall incidents, thereby reducing the risk of injury.

2. Enhanced Safety: By providing real-time monitoring and early warnings, millimeter-wave radar–based fall detection systems can significantly improve safety in third‑party restrooms. For individuals with special physical needs, falls can have serious consequences, making timely monitoring and alerts essential.

3. Intelligent Management: The millimeter-wave radar fall-detection system can be integrated with other smart systems in the third restroom—such as intelligent lighting and environmental monitoring—to enable more sophisticated, automated management. For example, when the system detects a fall, it can automatically activate emergency lighting, facilitating timely rescue efforts.

4. Customized Services: By taking into account users’ usage patterns and health conditions, the millimeter-wave radar fall-detection system can deliver tailored services. For example, for elderly individuals or people with disabilities, the system can configure more sensitive fall-detection thresholds to identify and respond to falls at an earlier stage.

In summary, the application of millimeter-wave radar–based fall detection technology in third‑party restrooms can significantly enhance safety, enable intelligent management, and provide users with more convenient and comfortable services.
