Resumen

This paper presents the design, implementation, and validation of an IoT-based geolocation system using the Sigfox network to enhance student safety in urban environments. The proposed system integrates a GPS NEO-6M module with a Ufox Devkit, enclosed in a portable housing, to provide low-power and real-time location tracking. A comparative evaluation of three visualization platforms identified Traccar as the most suitable solution, offering superior accuracy, interoperability, and response time. Field tests were conducted in five educational institutions in Ambato, Ecuador, achieving an average geographic accuracy of 4.5 m and operational efficiency ranging from 55% to 78%, depending on network coverage and urban interference. These results demonstrate the feasibility of Sigfox-based geolocation for reliable student monitoring and provide practical insights for deploying scalable, cost-effective safety solutions in educational contexts.
