This study evaluates the accuracy and effectiveness of the Sigfox geolocation system in comparison to the GPS GLONASS system with a focus on its implementation in urban and semi-urban environments of the city of Ambato, Ecuador. Field tests were conducted in several educational units to measure the accuracy of Sigfox in capturing geographic coordinates and its performance in comparison to GLONASS. The results showed that although Sigfox has a higher mean error than GLONASS, it offers adequate coverage and low energy consumption, making it viable for people monitoring and location applications in urban areas. The study also analyzed the impact of different data sending time intervals (15 s vs. 30 s) on the accuracy of the traced routes. A 15-s interval was found to significantly improve route accuracy and quality, especially in areas with good signal coverage. Despite these advantages, limitations in Sigfox accuracy were identified in areas with high building density and variable topography, suggesting the need to improve network infrastructure in these areas. The conclusions highlight the feasibility of Sigfox for IoT applications in urban environments, underscoring the need for additional studies to optimize its use in areas with complex geographical characteristics. This work contributes to knowledge about the application of LPWAN technologies in cities like Ambato and offers a basis for future research that seeks to improve the precision and effectiveness of geolocation systems in urban and semi-urban contexts.
