Demystifying 5G: The Strategic Evolution to Massive MIMO for Enhanced Network Capacity and Economic Gains
Main Article Content
Abstract
This paper delves into the world of 5G technology, focusing on the latest strategies and technologies being proposed globally. With over 14 billion devices connected, 5G networks are being implemented by the mobile telecom industry, aiming to increase capacity, connectivity, speed, accuracy, and trust. The paper also discusses the potential benefits of 5G technology, which are expected to deliver practical benefits over years, decades, and even centuries. It estimates that by 1930, 36 billion devices will be connected, transforming mobility into a ubiquitous connected environment of networks, devices, and inbuilt intelligence. The paper synthesizes key insights from technical presentations and literature on the evolution of wireless communications from traditional MIMO to Massive MIMO in the context of 5G, highlighting critical innovations, frequency spectrum characteristics, beamforming techniques, network architecture shifts, deployment challenges, and strategic imperatives for network operators. It also incorporates comprehensive details from recent academic contributions.
