Terahertz communication for 6G networks: Opportunities and challenges

This paper introduces terahertz communication technology, the core component of future 6 g wireless communication. Terahertz band communication can expand the spectrum range of communication, increase its capacity limit, and can be effectively utilized and realized in many fields. This paper systematically describes the background, development, difficulties and challenges of terahertz communication, as well as the possible application fields and development prospects in the future, and introduces in detail the key technologies of terahertz communication, including the simulation processing of terahertz signal processing and modulation technology and the research data of the system. In this paper, I use the ten-ray model modeling to help me understand the propagation characteristics of terahertz waves in different environments, and provide reference and guidance for the application of terahertz waves and system design. Finally, the future application field of terahertz are expanded and prospected. It describes new and predictable technologies that combine the power of terahertz technology with other technologies, such as exploring hybrid terahertz/optical wireless links, terahertz automotive applications, terahertz communications to enhance data center performance and terahertz 3D beamforming technology.
