Innovation for digital audio broadcasting: an interactive tool for monitoring coverage of this new technology in Colombia
Over the last few years, digital audio broadcasting has been expanding worldwide, highlighting the need to migrate to this technology in countries that still use analog broadcasting. In Colombia, both the Ministry of Information and Communications Technologies and the Communications Regulation Commission (CRC) have expressed the need to standardize and expand digital audio broadcasting to modernize the sector and improve the quality of transmissions, as it is currently the only one.
In this context, the National Open and Distance University (UNAD) has carried out preliminary studies through a research project funded by the Ministry of Science, Technology and Innovation. These studies include detailed simulations using licensed software to collect data from key geographic coordinates. The resulting data from these simulations, which were initially in KMZ format, presented a challenge due to their unstructured nature and their location on a licensed software's server.
This project addresses this issue by creating a web application that collects and displays this data graphically and interactively. The proposed solution is a software prototype that consists of a dashboard developed with Power BI and a complementary web application. The Power BI dashboard allows for detailed visualization and global analysis of the coverage data, while the web application is responsible for efficiently managing, storing, and making these dashboards public.
This article showcases the design, implementation, and testing of this software prototype, demonstrating its viability to transform raw data into useful and accessible information. The successful implementation of this system validates a methodology for handling large volumes of geographic data and demonstrates a tangible contribution to the future implementation of these types of technologies in Colombia.
