Future mobile services will require data transmission rates of 100 Gbps or higher due to the universalization of virtual and augmented reality devices. Therefore, THz technology, which uses an ultrahigh frequency band of 200 GHz or higher, is expected to be a candidate for such high-quality services. This article describes the current status of THz radio propagation characteristics, device and system developments, and network requirements to identify the overall trends in THz wireless communication technology.
