The rapid growth of mobile data traffic, supported via applications like extended reality (XR), communication-based holographic, and huge machine-type connectivity, led 5G network communications to the performance restrictions. Terahertz communication in 5G mobile communications has appeared as a promising solution for overcoming the limited spectrum lack and performing ultra-high data rates, in addition to capacity. This review paper supplies a thorough overview of modern evolution in Terahertz (THz) wireless communication systems, focusing on their potential to uphold data rates exceeding hundreds of gigabits per second. This review paper argues that the new key trends, like the availability of spectrum, the channels-based ultra-broadband, and consolidated arrays of utilized antennas, which are used to make THz communication necessary progress for the next generation of mobile communication systems. Crucial challenges consisting of coverage restrictions, propagation loss, hardware complexity, and scarcity of standardization are examined. Prospect strategies for mitigating such challenges have also been surveyed via the combination of intelligent considering surfaces, transceivers-based photonic-assisted, and characterized beamforming. Total, this paper concludes that THz mobile communication introduces a transformative move in realizing the ultra-high-capacity, very low latency, and high-efficiency aims of 5G mobile communications and beyond generations. The presented analysis in this review paper illuminates the practical trade-offs that presently restrict empirical deployment of THz and summarizes the extremely promising research study trends to get the better of them. This will provide a base for future expansion aimed at combining THz communication systems with 5G and beyond mobile communication network systems.
