TL;DR
This paper explores THz bands spanning $0.1$ THz to $10$ THz to support a human-centric 6G with high data rates, sensing and localization. It analyzes outdoor, indoor, and body-area THz networks and emphasizes their potential for precise human-body detection while identifying critical challenges such as range limitations, LOS requirements, and multi-band coexistence. The authors advocate RIS-enabled environment control and AI-driven generative learning for THz channel state information to realize robust integrated sensing and communication. The work highlights transformative applications in industry, biomedicine, and entertainment, underscoring that practical deployment will hinge on advances in beamforming, energy efficiency, security, and user comfort.
Abstract
This commentary dedicates to envision what role THz is going to play in the coming human-centric 6G era. Three distinct THz network types including outdoor, indoor, and body area networks are discussed, with an emphasis on their capabilities in human body detection. Synthesizing these networks will unlock a bunch of fascinating applications across industrial, biomedical and entertainment fields, significantly enhancing the quality of human life.
