Unleashing the Power of Tomorrow: Exploration of Next Frontier With 6G Networks and Cutting Edge Technologies

Abstract

As societal needs evolve, especially with the advent of demanding applications like remote surgeries in Smart Health, current communication systems struggle to meet the required latency and reliability for such use cases. Similarly, enhancing existing applications, such as increasing transmission rates in mobile networks to provide Quality of Service (QoS) and improved user experiences, presents complex challenges. The objective of delivering higher data rates is achieved by the 5G (fifth generation) wireless communication networks and are already been commercially deployed. However, with the proliferation of smart communication devices and the rise of IoE (Internet of Everything) applications, the existing 5G wireless communication networks face challenges in meeting the increasing demands for ultra-reliable, low latency communication. To address these limitations, researchers are focusing on the development of the sixth generation (6G) of cellular systems. Consequently, the selection of enabling technologies is crucial for designing a suitable 6G architecture that can address these evolving demands. The paper provides a broad review and survey of the prospective developments in the 6G networks. The main aim is to provide insights into the significant technologies for the future 6G, including their operation principles, potential applications, current research status, and associated technical challenges. This paper aims to offer valuable information for both industry professionals and academic researchers, while also identifying new research avenues in the field of 6G networks. This article proposes a methodology to analyze the relevance of enabling technologies and leverage it for designing an optimal 6G architecture. The evaluation results offer a unique perspective on 6G enablers, pinpointing issues and stimulating research for future mobile architectures. Additionally, the obtained insights provide researchers with essential information to stay updated on emerging enabling technologies and their suitability for crafting new and optimized 6G architectures.
