TRANSITIONING TO 6G WIRELESS: INVESTIGATING CORE TECHNOLOGIES, CHALLENGES, DEMANDS, APPLICATIONS AND RESEARCH AVENUES

Abstract

Amidst the expanding reach of 5G networks, researchers are increasingly uncovering limitations inherent in this technology, thereby sparking a surge of interest in the exploration and development of 6G, the forthcoming generation of cellular communication. Despite the specifics of 6G remaining nebulous, certain experts predict a transformative impact on mobile data usage and smartphone functionality. This review aims to consolidate ongoing research efforts and elucidate technological uncertainties surrounding the evolution of 6G. Expected to debut between 2027 and 2030, 6G is poised to introduce a new framework leveraging artificial intelligence. The integration of higher frequencies is anticipated to yield significantly accelerated data rates, expanded system capacity, reduced latency, enhanced security, and superior quality of service, with the overarching goal of providing high-speed gigabit Ethernet access to both businesses and consumers via their devices. This review examines various proposed technologies for enabling 6G communication, along with key performance indicators (KPIs) for the network, potential challenges, and directions for future research.
