PlaceLab
PlaceLab is a research platform that uses Wi-Fi signals from smartphones and other devices to determine people's locations indoors, such as in shopping malls or offices. Unlike GPS, which works well outdoors, PlaceLab analyzes variations in Wi-Fi signals to create detailed maps of indoor spaces and track movement. This helps researchers improve indoor navigation systems, enhance spatial understanding, and develop smarter building designs. It combines hardware sensors and software algorithms to accurately identify where users are without needing dedicated devices, making location-based services more effective inside complex environments.
