Spectrum Management: Agencies Should Strengthen Collaborative Mechanisms and Processes to Address Potential Interference

2 min read
<div>What GAO Found The Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) regulate and manage spectrum, and other agencies, such as the National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA) are among federal spectrum users. To address potential interference among proposed uses of spectrum, these agencies employ various coordination mechanisms. For domestic matters, the agencies coordinate through an NTIA-led committee that provides input to FCC’s spectrum proceedings. For U.S. participation in the International Telecommunication Union’s (ITU) World Radiocommunication Conferences (WRC), agencies coordinate via a preparatory committee that provides input used to develop U.S. positions that the Department of State submits to a regional body or directly to the WRC (see figure). Technical Coordination Process for U.S. Participation in WRC These mechanisms reflect some key collaboration practices but do not fully reflect others. For example, while the documents that guide coordination between FCC and NTIA and the preparatory committee emphasize reaching consensus whenever possible, there are no clearly defined and agreed-upon processes for resolving matters when agencies cannot do so.

GAO’s review of U.S. participation in ITU’s 2019 WRC shows that these issues affected collaboration.
