Sixth Generation (6G) Wireless Networks: Vision, Research, Challenges, and Solution

Resumen

Fifth generation (5G) wireless networks were unable to meet certain performance standards; however, sixth generation (6G) wireless networks will set novel benchmarks. This is a result of the increasing demands on an increasingly smart system, with ultra-low delay, extremely fast connections, and the ability to handle a vast array of interconnected programs. The substantial spare and undiscovered bandwidth in the frequency ranges beyond 100 GHz makes them the most attractive for 6G wireless communication networks. In addition to presenting the architecture of an ultra-massive MIMO (ultra-mMIMO) composite beam structuring network for multiple users and its viability for operation at THz frequency ranges, this study initially gives a thorough explanation of the 6G concept. Employing performance indicators such as error vector size, symbol constellations, and antenna array radiating beams, the suggested framework's operation is confirmed at higher-order modulating plans to obtain greater spectrum efficiencies. The performance findings highly advise using more data flows per user to obtain greater speeds that meet the requirements of 6G wireless networks, and they advise employing a specific mMIMO antenna configuration depending on the proportion of distinct data flows per user. © 2024 IEEE.
