Panel Discussion: The Spectrum above 100 GHz

Recorded Webinar: September 29, 2022

Topic:

The Spectrum above 100 GHz: Reality Check by the mmWave Coalition

Abstract:

Wireless communications in the sub-terahertz and terahertz (THz) bands (or broadly speaking, from 100 GHz up to 10 THz) have been envisioned by both academia and industry as a key enabler of future sixth generation (6G) wireless networks. In the last five years, there has been major progress towards closing the so-called THz gap: testing, infrastructure and user technologies are quickly evolving; misconceptions relating to terahertz-wave propagation and interference have been cleared; and innovative signal processing, communication and networking protocols have been proposed; all while new question marks have risen, such as those concerning to the security of terahertz links or the coexistence between active and passive users of the spectrum above 100 GHz.

In this interactive panel, several members of the mmWave Coalition will provide an updated look at the opportunities and challenges in the spectrum above 100 GHz and jointly identify the next key milestones for the practical development and adoption of the field.

Going 6G

New Sub Terahertz R&D Testbed for 6G Research

Recorded Webinar
September 22, 2021
Presented by Greg Jue, Keysight Technologies

Abstract:

Sub-Terahertz (sub-THz) frequencies (100-300 GHz) with extreme modulation bandwidths are part of early 6G research. This presents many unknowns. One of those unknowns is exploring the level of system performance that is achievable and reasonable given new frequency bands, extreme modulation bandwidths, and new waveforms. This webinar will provide insight into this by discussing new sub- terahertz system-level design and test challenges presented by 6G. EVM measurement results at 140 GHz will be shown with varying waveforms and bandwidths up to an occupied bandwidth of 10 GHz. Low Signal-to-Noise (SNR) ratios are a challenge for wide bandwidth waveforms at sub-THz frequencies. Preamble and pilot-aided synchronization and channel estimation will be discussed to achieve more robust demodulation in low SNR environments. Understanding and addressing channel impairments at sub-THz frequencies will be another challenge. Sub-THz channel sounding will be discussed and the testbed receiver will be customized with a real-time adaptive equalizer FPGA implementation to address channel impairments.

Presenter:

Greg Jue is a 6G System Engineer at Keysight Technologies working on emerging millimeter-wave applications beyond 110 GHz. Greg authored Keysight’s new whitepaper “A New Sub-Terahertz Testbed for 6G Research”, and was a technical contributor to Keysight’s new “Engineering the 5G World” ebook.

Presented by Professor Theodore Rappaport, NYU WIRELESS

Presentation by Professor Theodore (Ted) Rappaort to the member companies of the NYU WIRELESS Industrial Affiliates Program. In this mini-lecture series Ted gives an overview of the expansion of communications into the Terahertz frequency spectrum.

Summaries of the results of experiments at the NYU campus provide insight into the development of communications potential at these very high frequencies (100++ GHz). Also discussed are the required behaviors of antennas, and the need to study the important topic of potential safety aspects of these higher frequencies.

As Ted says, “There is clear sailing up to 800 GHz.”
