ISART 2015: Measurements, Models, Simulations, and Technologies for Improved Spectrum Sharing

Background

Beginning in 2010, as a response to diminishing opportunities for clearing government spectrum for new commercial systems, NTIA's Institute for Telecommunication Sciences (ITS) held ISART conferences that focused on spectrum sharing. The participants and attendees at the three most recent ISART events discussed and debated the technical, regulatory, and economic factors that influence the spectrum-sharing paradigm. These symposia investigated spectrum sharing opportunities and challenges between radars and communications systems; evaluated the potential for expanded use of near real-time database systems, sensing, and other approaches to more dynamically access spectrum; and addressed the obstacles to development of a spectrum sharing infrastructure, business processes, and rules for federal and commercial sharing.

In 2012, NTIA's Commerce Spectrum Management Advisory Committee (CSMAC) established a number of working groups made up of industry and government stakeholders. These working groups investigated spectrum relocation and sharing options for federal government systems in the 1695-1710 MHz and 1755-1780 MHz bands to accommodate new commercial broadband uses. While largely a success, the working group reports [WG-1] [WG-2] [WG-3] [WG-4] [WG-5] exposed a number of opportunities to enable more widespread spectrum sharing across the country. Recurring themes expressed by CSMAC members and working group participants included the need for more sophisticated and accurate interference prediction models together with simulations, measurements, and tests to better assess inter-system compatibility. These analyses exposed a number of promising system adaptations and assessment approaches that should be further evaluated, prioritized, and shepherded through standards development processes to accelerate the evolution of spectrum-sharing technologies for commercial and government systems. Verification and validation of new analytic techniques and technologies will be essential to developing stakeholder consensus and more intense use of the radio spectrum resource.
