The International Symposium on Advanced Radio Technologies (ISART) is a US government-sponsored conference that brings together government, academia, and industry leaders for the purpose of collaborating on groundbreaking developments and applications of advanced radio technologies.
ISART 2015: Measurements, Models, Simulations, and Technologies for Improved Spectrum Sharing
May 12-14, 2015 • Boulder, Colorado
ISART 2015 was the 14th in the series of high quality symposia bringing together the world's experts on advanced radio systems development. ISART 2015 was sponsored by the new Center for Advanced Communications, a joint effort between NTIA and the National Institute of Standards and Technology (NIST) that was announced in 2013.
The goals of this conference were to present updates on the current state of the art in spectrum compatibility analyses, research into improved spectrum analysis techniques, emerging technologies that further promote spectrum sharing, the means by which spectrum analyses may be adapted to accommodate new technologies, and, in turn, the means by which underlying technologies can be adapted to exploit spectrum sharing opportunities exposed in previous studies. The 2015 conference continued a focus on spectrum sharing that began with ISART 2010, encompassing discussion and debate on the technical, regulatory, and economic factors that influence the spectrum-sharing paradigm. Spectrum sharing offers opportunities and challenges; ISART offers a venue to explore and propose ways to overcome obstacles to development of a spectrum sharing infrastructure, business processes, and rules for federal and commercial sharing.
In the nature of a prequel, two tutorials were offered May 12. These provided essential background for:
- ISART participants who are not familiar with the findings of the Commerce Spectrum Management Advisory Committee (CSMAC) Spectrum Sharing Studies that led to recommendations about approaches to sharing, transition and/or relocation of the government spectrum dependent systems
- Engineers, statisticians or other participants interested in understanding the proper techniques and added complexity of incorporating higher order statistics into spectrum engineering analyses, as has been done in developing the European Conference of Postal and Telecommunication (CEPT) Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT).

To take advantage of potential synergies, several no-cost spectrum research related events were scheduled during the same week as ISART.
WSRD Meeting 9:00-11:00 a.m. on May 12: The Wireless Spectrum R&D (WSRD) Senior Steering Group (SSG) was formed in late 2010 to coordinate spectrum-related research and development activities both across the Federal government and with academia and the private sector. The May 2015 monthly WSRD meeting will take place the morning of May 12, just prior to the opening of ISART. For more information, visit the WSRD Web site.
CSMAC Meeting 1:00-5:00 pm on May 12: The Commerce Spectrum Management Advisory Committee (CSMAC) advises the Assistant Secretary for Communications and Information at NTIA on a broad range of spectrum policy issues. Committee members are spectrum policy experts from outside the Federal government who offer expertise and perspective on reforms to enable new technologies and services, including reforms that expedite the American public's access to broadband services, public safety, and long-range spectrum planning. Members serve in a personal capacity and do not represent any organization or interest. CSMAC meets several times a year and meetings are open to the public.

Post-ISART Workshop on May 15: Factors to Consider for Undertaking Realistic Mobile Broadband Sharing Studies: From 2012 through most of 2013, NTIA's Commerce Spectrum Management Advisory Committee (CSMAC), working with U.S. mobile industry participants and affected Federal agencies, investigated possible spectrum relocation and sharing options for federal government systems in the 1695-1710 MHz and 1755-1780 MHz bands to accommodate new commercial broadband (i.e., LTE) uses. The effort focused on resolving issues associated with widespread spectrum sharing of these bands across the United States. While the CSMAC work was able to provide a worthwhile initial assessment of the magnitude of the challenges posed by federal-commercial sharing, issues remain that must be addressed in order to further develop and refine the system compatibility models and simulations to maximize the potential for spectrum sharing. Prominent among these is the need for more sophisticated and accurate interference prediction models, together with more realistic simulations of the interference (LTE) operational environment. The purpose of this workshop was to discuss a plan of action to address short-comings in interference simulation of advanced radio technologies relevant to the proposed sharing scenarios. This forum could provide a basis for further collaborative research between the U.S. Government and mobile broadband industry on spectrum sharing issues to benefit all concerned. Representative members of the U.S. mobile industry described how the mobile industry simulates advanced broadband networks (LTE) and what parameters are key (e.g., building entry loss, accurate non-line of sight propagation data, appropriate operational environments…) for spectrum sharing simulation studies. The focus was on identifying those essential “must have” aspects of a typical complex mobile broadband system widely in use that are deemed necessary for a reasonable study and why they are important. Workshop leaders did not necessarily address numerical values of parameters per se, but rather highlighted what factors are critical in LTE system modeling.
