PL2: Spectrum Sharing and Coexistence above 100 GHz

Presentation Abstract
In an increasingly congested spectrum landscape, companies, regulators, and policymakers are looking at new frequencies. With large chunks of untapped bandwidth, and the increasing maturity of the required technology, the sub-THz band offers significant promise for the wireless communications world. At the same time, existing services and stakeholders in the band, e.g., from the passive remote sensing and radio astronomy communities, need to be protected. Finally, international and national regulations limit emissions above 100 GHz largely based on considerations derived at lower frequency, overlooking the unique characteristics of electromagnetic wave propagation above 100 GHz, e.g., molecular absorption, and of the corresponding technology, e.g., the extreme directivity of the antennas. There is a growing need for 1) new propagation models and measurements across frequencies that capture the stakeholders’ diverse needs and ways of interacting with the spectrum; 2) new circuits, antenna designs, and interference cancellation techniques for sharing and coexistence; and 3) dialogue between the scientific and other stakeholders to understand and model Radio Frequency Interference. With this panel, we want to foster the dialogue between often siloed communities. To do so, we have invited representatives from the wireless communications, radioastronomy, and remote sensing community, including policy advocates and experts.
