A system has been created in Russia that determines a person's location using Wi-Fi with an accuracy of 5-7m

Scientists from the Siberian State University of Telecommunications and Informatics (SibSUTI) have developed a domestic system for determining a person's location indoors with an accuracy of 5-7 meters using Wi-Fi.

This new development is unique because mobile networks can only determine the location with an accuracy of 300-500 meters, and satellite signals may not penetrate through walls and other obstacles. This was reported by TASS.

The system can be used for search operations inside buildings, mines, and underground facilities, parental control of schoolchildren, and to help people with disabilities navigate large buildings.

A device with Wi-Fi access identifies the parameters of Wi-Fi access points and the signal levels from these points to the target object. The system collects this information and sends it to a server, where the distance to each point is calculated, and the coordinates of the object are determined. The more Wi-Fi points around, the more accurate the result.

Anatoly Kostyukovich, head of the center and associate professor of the Department of Infocommunication Systems and Networks (IKSS) at SibSUTI, noted that the domestic market is predominantly represented by foreign analogs of such a system, which are difficult to certify in Russia due to the potential for precise tracking of people's locations.

The system has already been tested in a school in Novosibirsk and will allow parents to track the location of their children through an application.

Currently, an algorithm for tracking is being developed, which will allow determining the direction of the object's movement.
