5G represents the most recent mobile communica- tion technology which aims to improve speed, reduce latency, and offer more reliable connections than past versions. This document provides an insight into 5G network architecture and describes the main network components such as the core network and radio access network. Additionally, the document covers the technologies used in the implementation of 5G communications and different uses cases such as IoT, smart cities, self-driving cars, and telemedicine. The document demonstrates the contribution of 5G technology towards modern digital services. In addition to the benefits of increased throughput, latency reduction, and device density capabilities, several significant problems remain unsolved – from the issue of mmWave propagation restrictions and the energy consumption associated with the densification of networks to compatibility with legacy systems and fragmentation in global standardization. The comparative study demonstrates the advantage of AI/ML-based solutions for autonomous network management. Finally, the document outlines critical research questions and suggests prospective directions for further re- search.
