Abstract
Sixth Generation (6G) communication networks, leveraging advanced technologies such as Terahertz (THz) waves, Artificial Intelligence of Things (A IoT), and Non-Terrestrial Networks (NTN), have created new horizons in the field of communications. This study aims to analyze the main challenges and opportunities facing the development of 6G. The research method is based on a systematic review of scientific sources, analysis of technical challenges, and examination of proposed solutions in the areas of high frequencies, cybersecurity, distributed machine learning, and the architecture of future networks. The results indicate that the attenuation of terahertz waves, novel security threats, and the need for innovative architectures are considered key obstacles in the implementation of 6G. To overcome these challenges, technologies such as Intelligent Reflecting Surfaces (IRS), distributed data-driven networks, and advanced learning algorithms have been proposed as effective solutions. Finally, this research emphasizes the importance of convergence among research, industrial, and policy-making institutions to develop global standards and facilitate the path towards intelligent, secure, and sustainable societies.

Keywords: Sixth Generation Networks (6G), Terahertz Communications (THz), Artificial Intelligence of Things (A IoT), Non-Terrestrial Networks (NTN), Cybersecurity, Sustainable Energy, Distributed Machine Learning.
