Ultrabroadband Communication and Networking Solutions to Unleash the Spectrum above 100 GHz
November 17, 2021 @ 1:00 pm - 2:00 pmFREE
Abstract: Terahertz (THz)-band (0.1–10 THz) communication is envisioned as a key wireless technology in 6G and beyond systems. In the last decade, the THz technology gap has been progressively closed through major advancements in electronic, photonic, and plasmonic technologies. In parallel, the propagation of THz signals has been studied through both physics-based and data-driven approaches, debunking some of the myths about the THz channel. Nevertheless, there are several communication and networking roadblocks that need to be overcome to unleash the spectrum above 100 GHz. In this talk, the state of the art and open challenges at the physical, link and network layers of THz communication systems will be presented. Specific topics include novel ultrabroadband waveforms designs that can not only overcome but leverage the distance-dependent bandwidth resulting from molecular absorption; intelligent reflecting surfaces able to engineer wavefronts in ways that in the past were only available to optical systems; new receiver initiated medium access control protocols for ultra-directional links coupled with expedited neighbor discovery strategies’ and cross-layer multi-hop relaying strategies. Moreover, a glimpse at state-of-the-art experimental platforms for THz communication networks will be provided.
