Scientists from the Siberian State University of Telecommunications and Informatics (SibGUTI) have developed a system that can detect people’s location inside buildings with an accuracy of 5-7 meters using a Wi-Fi network. This greatly exceeds the capabilities of mobile networks, which usually determine location with an accuracy of 300-500 meters and are not suitable for use inside buildings, especially in industrial areas and mines.
The system, developed by experts from Novosibirsk, is designed for a variety of purposes, from ensuring the safety of children and disabled people to helping navigate inside large buildings. It works based on trilateration, collecting signal data from Wi-Fi access points to determine the exact location of an object.
The problem of limited indoor location accuracy is caused by weak signals from GPS and GLONASS satellites. The system developed at SibGUTI aims to solve this problem and can be used in schools where parents can track their children’s movements through a special mobile application.
