Wi-Fi sensing technology uses existing Wi-Fi signals to detect movement, monitor environments, and enable smart applications in homes and buildings.

 

 

This is a technology that utilizes existing Wi-Fi signals to detect and interpret events or changes in an environment.

 

Wi-Fi sensing takes the advantage of the fact that Wi-Fi signals can bounce off objects and surfaces in the environment. By analyzing changes in the Wi-Fi signal characteristics, such as signal strength, time of flight, phase, and frequency, it's possible to extract information about the movement, presence, and the behavior of people or objects within the coverage area of the Wi-Fi network.

 

 

This technology typically involves the use of sensors, but not necessarily in the traditional sense of physical hardware devices. Instead of dedicated sensors, Wi-Fi sensing relies on the existing Wi-Fi infrastructure and the signals transmitted by Wi-Fi devices (such as routers, smartphones, laptops) to gather information about the environment.
