Wireless communications in the sub-terahertz band (sub-THz, from 100 GHz up to 300 GHz) have been envisioned by both academia and industry as a potential enabler of future wireless networks beyond 6G. The very large available bandwidth at these frequencies offers enormous potential to alleviate the spectrum scarcity problem and break the capacity limitation of existing wireless communication systems. Consequently, sub-THz communications are expected to support epoch-making wireless applications that demand reliable multi-terabits per second data rates, ranging from holographic communications, extended reality, and ultra-high-definition content streaming among mobile devices, to wireless backhaul connectivity and even satellite communication networks that can help us bridge the digital divide. In addition, beyond communications, the sub-THz band opens the door to new forms of wireless sensing beyond radar and localization, including air quality monitoring, smart agriculture, and healthcare monitoring.
In this tutorial, we will provide a new and comprehensive look at the field of sub-THz wireless systems, (i) explaining novel system architectures for directional steering and joint communication and sensing and (ii) highlighting the key challenges in directional MAC and recent developments for mobile blockage-resilient connectivity; and (iii) explaining the unique properties of these frequencies for wireless sensing and perception. Emphasis will be given to understand the mathematical tools, simulation platforms, experimental testbeds, and data-sets available to the community.
The tutorial will be held at the ACM MobiCom 2025 premises. The exact date and location of the tutorial (building and room number) will be announced closer to the conference dates.
