Theoretical Approaches to 6G Networks: Envisioning the Post-5G Communication Paradigm

The transition from 5G to 6G represents a paradigm leap in wireless communication, allowing for higher speeds, reduced latency, and more connection. This article investigates the theoretical approaches that underpin 6G, focusing on new technologies such as terahertz (THz) communication (Rappaport et al., 2013; Zhang et al., 2020), artificial intelligence (AI) integration (Fang et al., n.d.; Junejo et al., 2024), and edge computing (Borgianni, n.d.). With 6G positioned to enable applications such as holographic communication and real-time autonomous systems (Butt et al., 2024), this research delves into the fundamental concepts that will drive innovation in next-generation networks. The research also tackles the difficulties of energy efficiency (Başaran et al., 2024), spectrum distribution (Khamesra et al., 2024), and security in highly autonomous networks (Fang et al., n.d.; Gabriel et al., 2018). The current research examines the potential of 6G to provide insights into the future of wireless communication and the societal and economic effects of ubiquitous, ultra-reliable access. The study additionally highlights the importance of continual innovation in overcoming technological and operational hurdles.
