NSF SII-NRDZ HCRO-NRDZ Field Deployment

Public accessibility to RF noise measurement studies - A cloud-based architecture will be utilized to host a research community Open RF Data Set repository and provide tools for community analytical purposes to encourage community-wide collaboration. RADYSIS will perform and publish baseline RF noise surveys that can be analyzed and built upon by a larger community. RADYSIS will enable collaborative measurement, analysis, and characterization of RF noise, and long-term analysis of RF noise trends. 

Dynamic spectrum sharing between passive and active systems - Many instances of dynamic spectrum sharing exist, ranging from the local sharing between low power systems such as Wi-Fi and Bluetooth, to the more recent sharing between broadband services and radars. This is spectrum sharing between active services, and relies on sensing transmissions, which is not possible with passive systems such as radio telescopes. As spectrum becomes increasingly scarce, passive systems are likely to lose exclusive allocations and will be forced to share. RADYSIS will prototype and deploy dynamic sharing mechanisms and quantitatively evaluate applicability to bi-lateral spectrum sharing. RADYSIS will include earth-orbiting, passive-sensing, EESS satellites into a generalized spectrum sharing architecture. 

Evolution towards the Definition of an NRDZ - An NRDZ is effectively a geographic region within which bi-lateral spectrum sharing takes place. The research performed at the HCRO/SETI facility on bi-lateral spectrum sharing will enable preliminary definition of the requirements and operating procedures for the NRDZ community. There is an important need to integrate the manual policy and regulations process to support NRDZ stakeholders as a capability of the automated system – this is a challenge to be addressed.

The research and engineering domain - The RADYSIS results will improve the ability of RA to operate in environments with large amounts of radio frequency interference, particularly as RFI from satellite constellations increases and as RA instrumentation bandwidths increase beyond the traditional protected bands. RADYSIS will impact the commercial sector, as RADYSIS analyses and experiments on spectrum sharing will provide data and tools to organizations developing/deploying new systems – and upgrading existing systems – that will be required to share spectrum. 

The education domain - Over the foreseeable future, the demand for RF engineers and scientists is expected to increase. Similarly, issues with RF noise, wireless coexistence, and spectrum sharing will become more prevalent and more complex. RADYSIS will organize the best practices and lessons learned from the project into a curriculum for educating the next generation of scientists and engineers in the basics of surveys and analyses of both RF noise and spectrum sharing. The RADYSIS team will conduct workshops on topics to bring the NRDZ and RA communities together to share knowledge. RADYSIS activity participation and results will aid to develop national workforce expertise. 

The regulatory domain - Spectrum regulatory agencies in the U.S., the FCC and the NTIA, are grappling with spectrum sharing. The studies, analyses, simulations, experiments and site deployment conducted by RADYSIS will inform the spectrum community and the regulatory agencies in the U.S. and abroad about the effectiveness of mechanisms for dynamic spectrum sharing and bi-lateral spectrum sharing.
