Recent advancements in communication have led to many new applications, including extended reality, holographic display, and edge computing that require data rates in the order of Tbps low latency and high reliability. Even with the introduction of many promising technologies, existing 5G cannot provide the high data rate required for these applications. This has led researchers to explore what 6G will be like. Given the potential of terahertz (THz) communications systems to provide such data rates over short distances, they are widely regarded to be the next frontier for wireless communications research. This talk provides a comprehensive overview of THz bands with particular emphasis on their propagation characteristics, channel models, design and implementation considerations, and potential applications to 6G wireless. It will also discuss stochastic geometry based analytical approaches to model and analyze THz networks from a system level perspective. The talk will also briefly look at other potential candidates of 6G and beyond communications.
