GLOBAL ANALYSIS OF MOBILE BROADBAND NETWORK PERFORMANCE: INSIGHTS INTO 5G DEPLOYMENT AND FUTURE 6G CHALLENGES

This research focuses on analyzing the global experience of evaluating the performance of mobile broadband (MBB) networks in the context of 5G deployment and preparation for 6G. The study examines key quality of service (QoS) and quality of experience (QoE) metrics, such as data download speeds, latency, connection stability, and network coverage. Special attention is given to the analysis of mobile operators in Kazakhstan, where 5G technology is being deployed by a limited number of operators, and the current state of infrastructure is assessed. The research also includes examples of international practices aimed at improving the quality of mobile networks, such as studies in the USA, Malaysia, and Oman, highlighting global trends and challenges associated with the development of next-generation mobile networks. The paper also outlines the role of advanced technologies, such as millimeter waves, beamforming, and Massive MIMO, in ensuring reliable connectivity in high-density environments. Finally, a mobile application architecture for real-time signal analysis in 5G networks is proposed, designed to assess mobility management and load balancing processes in next-generation networks.
