KAIST researchers have developed an indoor positioning system based on "Wi-Fi fingerprints" from mobile devices and signal strengths from APs
To test the method, the research team collected 7,000 Wi-Fi fingerprints at 400 access points in four selected areas in Korea
Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed a new indoor positioning system that makes it possible to build a Wi-Fi radio map that does not require GPS signals. It's claimed to be an improvement on Wi-Fi Positioning Systems, that rely on both GPS and Wi-Fi signals.
