Intelligent home presence, without compromising privacy
WINP is a research and development project focused on the study and application of WiFi sensing technology to produce an accessible, low-cost real-time indoor locationsystem.
The project explores an innovative approach that uses existing WiFi networks not only for connectivity, but as a tool for perceiving the environment, overcoming the limitations of GPS technologies and traditional indoor systems based on dedicated infrastructures.
The research was conducted internally by N&C’s R&D team and has led to the development of experimental models and working prototypes, validated in real-world contexts such as offices and warehouses.

Abstract of the scientific publication
‘This paper presents WINP, a low-cost indoor localisation system that leverages existing WiFi infrastructure for real-time asset tracking. By combining Channel State Information (CSI) with Support Vector Machine (SVM) classification and a Kalman Filter, WINP achieves high spatial accuracy and temporal stability. The system uses standard hardware and software-defined radios to extract CSI features, which are processed to estimate position and refined through probabilistic filtering. Extensive experiments in warehouse and office environments demonstrate sub-meter accuracy and robust tracking performance. WINP’s modular architecture enables scalable deployment in dynamic indoor settings, making it suitable for industrial, commercial, and smart building applications.’
