Universal access to education based on Software Defined Radio (SDR): The case of Mali

This study presents an innovative solution to improve access to education in Mali using a private 4G/5G mobile network based on software-defined radio (SDR) technology. Faced with the persistent challenges of the Malian education system, including insecurity, recurrent strikes, and lack of infrastructure, our approach integrates cutting-edge technologies to offer a resilient and flexible alternative. The proposed architecture combines 5G Non-Standalone (NSA), SDR, and an IP Multimedia Subsystem (IMS) to create a comprehensive educational ecosystem, including an online learning platform. Our experiments demonstrate the technical feasibility of this solution, with successful 5G connectivity and educational content streaming tests. The results show that this approach can effectively extend network coverage in underserved areas and provide educational services even in challenging conditions. While challenges remain in terms of scalability and security, this research opens new perspectives to reduce the digital divide in education in developing countries facing similar obstacles.
