Review on 6G communication and its architecture, technologies included, challenges, security challenges and requirements, applications, with respect to AI domain

Abstract

The evolution of wireless communication systems has led to the emergence of the sixth generation (6G) communication architecture, characterised by transformative technologies and novel paradigms that transcend the capabilities of its predecessors. This paper presents an overview of the various aspects of 6G communication architecture, focusing on its technologies, challenges, and applications within the domain of artificial intelligence (AI). The abstract provides an overview of a review on 6G communication, focusing on its architecture, technologies, challenges, security concerns, and requirements within the context of the AI domain. The paper explores the evolving landscape of wireless communication, delving into the anticipated features and capabilities of 6G networks. The architecture emphasises the integration of AI-driven elements, such as intelligent resource allocation and autonomous network management. Various technologies, including terahertz frequencies and integrated satellite networks, are discussed in terms of their potential to reshape connectivity paradigms. However, alongside the promises, a multitude of challenges arise. These encompass spectrum scarcity at terahertz frequencies, energy efficiency concerns, and the need for global standardisation. Addressing security challenges is crucial, considering the expanded attack surface and the integration of AI-powered functionalities. The paper also delineates the stringent requirements that 6G must fulfil, spanning ultra-low latency, high bandwidth, massive device connectivity, and reliable communication. Contextualising these discussions, the review highlights applications within the AI domain that stand to benefit from 6G advancements. These include edge AI, augmented reality, autonomous systems, and IoT-enabled environments. By synergising cutting-edge wireless capabilities with AI-driven intelligence, 6G is poised to revolutionise industries and societal experiences in unprecedented ways.
