Abstract
Millimeter-wave (mmWave) technology has improved to overcome propagation issues and enable high data speeds in 5G and 6G wireless networks. The capabilities of 5G networks are limited in their ability to support future applications such as extended reality and 3D gaming. Terahertz (THz) transmission, a key component of 6G networks that enable fast data transmission over short distances, has consequently attracted increasing attention. Addressing challenges, including signal interference, antenna design, regulatory compliance, and security concerns, is essential for realizing the full capabilities of wireless communication in the mmWave and THz frequency ranges.The Terahertz Channel Analysis Framework for Next-Generation Wireless Networks (TCAF-NGWN) examines complex design components, channel models, and signal propagation in the mmWave and THz bands. The report evaluates these bands' capabilities to fulfill 6G networks' evolving communication needs and examines commercial application standardization efforts. 6G terahertz communication channel research mainly occurs in academic labs and focuses on antenna arrays, channel properties, and transmitter/receiver combinations. Signal transmission is analyzed for route loss, multipath fading, signal attenuation, reflections, obstacles, and diffraction. Channel capacity, data rate, reflection coefficients, and signal-to-noise ratio are evaluated. The study analyses the theoretical models and improves communication systems using literature and datasets like the Terahertz Wireless Channel Dataset. Comparing the suggested model to THz-IRS, UM-MIMO, and CDOT shows its advantages. The research advances terahertz wireless communication technologies by providing insights into channel propagation and system performance in practical circumstances through precise experimental setups and measuring techniques.
