In August, the Federal Communications Commission (FCC) issued a special invitation. In a Notice of Inquiry (NOI), it called upon researchers and others to help the FCC use “today’s tools to understand tomorrow’s commercial spectrum usage.” SpectrumX, a National Science Foundation (NSF) Spectrum Innovation Center, rose to the occasion. It submitted a center NOI comment with ten contributing authors and eight center endorsers.
During the week of July 10, 2023, faculty and researchers at the University of Colorado Boulder (CU Boulder) hosted participants from five continents for the United States Telecommunication Training Institute (USTTI). Each day of the five-day course focused on a new topic: trends and impact in telecommunications, spectrum management and radio frequency technology, law and regulatory aspects around the globe, technology and innovations, and participant case study presentations.
In early January, radio science researchers from across the United States and beyond came together for the National Radio Science Meeting (NRSM) at the University of Colorado Boulder. The meeting was attended by six SpectrumX members, who hosted workshops and participated in multiple panel discussions. The NRSM is sponsored by the U.S. National Committee for the International Union of Radio Science.
Interference conflicts are ongoing challenges within the radio spectrum field. Within the U.S. spectrum ecosystem, commercial wireless networks for communication, internet access, scientific sensing for both environment and radio astronomy, broadcast, radar, position/navigation/timing, and more create a sometimes crowded atmosphere where signals compete.

NSF SpectrumX actively encourages and supports its members to contribute to regulatory and policy proceedings on radio spectrum issues. Center members submit policy comments and testify at congressional hearings to […]

The FWG is currently working with leadership from NSF funded PAWR platforms to determine how SpectrumX can partner with these facilities to conduct relevant spectrum sharing experiments. SpectrumX currently has […]

The first NSF SpectrumX flagship project focuses on developing a combination of tools, infrastructure, and team capabilities to enable the execution of a series of increasingly complex flagship project experiments. […]
