ABSTRACT

The exponential growth of wireless data traffic and the emergence of advanced applications such as holographic communication, immersive virtual reality, digital twins, autonomous transportation, and smart industrial systems have created unprecedented demands for ultra-high-speed communication networks. Existing fifth-generation (5G) communication systems are approaching their performance limitations in terms of spectrum availability, data rates, and network capacity. Terahertz (THz) communication has emerged as a promising technology for future sixth-generation (6G) wireless networks due to its ability to provide extremely wide bandwidth, ultra-high data transmission rates, and low-latency communication. Operating within the frequency range of 0.1–10 THz, THz communication enables data rates exceeding several terabits per second while supporting massive connectivity requirements. However, challenges such as severe propagation losses, atmospheric absorption, hardware complexity, and beam alignment remain significant obstacles to practical deployment. This paper presents a comprehensive study of Terahertz communication systems, reviews recent technological advancements, and proposes an Intelligent Adaptive Terahertz Communication Framework (IATCF) that integrates artificial intelligence, adaptive beamforming, and dynamic resource management. Simulation analysis demonstrates improved throughput, reduced latency, and enhanced communication reliability compared with conventional wireless architectures. The findings indicate that THz communication will play a critical role in enabling future intelligent communication ecosystems.
