Wi-Fi, a cornerstone of modern connectivity, is evolving beyond its traditional role of internet access. Researchers are now exploring its ability to track movements inside buildings using Wi-Fi mapping technology, a concept that could revolutionize industries like smart homes, healthcare, and security. This innovative technology leverages existing Wi-Fi signals to detect and visualize human presence and movements, all without requiring additional devices like cameras or sensors.
What Is Wi-Fi Mapping Technology?
Wi-Fi mapping technology is an advanced method of using signal interference patterns to identify objects, detect movements, and map indoor spaces. By analyzing how Wi-Fi signals interact with their surroundings, this technology creates a virtual representation of activity within a building.
How Wi-Fi Mapping Technology Works
- Signal Interaction:
Human bodies and objects disrupt Wi-Fi signals as they move through a space. - Data Collection:
These disruptions are captured and analyzed by the system. - AI Integration:
Artificial Intelligence interprets the data, converting it into a map of movements and locations.
