SPEAKER_04: Thank you for being here today. It's my great pleasure to be here today to discuss the United States' preparation for the 2027 World Radio Communication Conference. The World Radio Communication Conference, convened by the International Telecommunication Union every four years, is one of the most consequential global forays into spectrum policy. The decisions made at these conferences shape the international rules governing how radio frequency spectrum is allocated and shared around the world. Those decisions have far-reaching implications for United States economic competitiveness, national security, scientific research, and the continued leadership of the United States in wireless and satellite technologies. Next year's conference will be hosted in Shanghai, and the Chinese Communist Party will certainly be prepared to advance positions meant to undermine the United States' leadership. The United States must enter these negotiations with a strong position. This requires a tightly coordinated interagency process. This process, which is led by NTIA, begins with federal agencies providing technical input and operational perspectives on each agenda item under consideration for Work 27. The United States' final position should reflect the full range of national spectrum interests. Among agencies, the Department of Defense plays a particularly significant role. DOD is the largest federal user of radio frequency spectrum within the federal government, and many of its most critical capabilities, including satellite communication, radars-I had a dog named Radar-radars, and missile warning systems depend on reliable and interference-free spectrum assets. As the work agenda looks to address space-related services and satellite operations, the intersection between international spectrum policy and national security becomes even more pronounced. National security missions cannot simply be engineered around certain commercial spectrum priorities. This is exactly why Congress exempted 7.4 to 8.4 gigahertz band from FCC auction authority last year, in addition to the lower three band. Other federal agencies also contribute essential expertise to the interagency process. NASA and NOAA depend on spectrum for scientific satellites and weather monitoring systems that are crucial for forecasting and climate observation. The FAA relies on spectrum for aviation safety and navigation systems that support the integrity of the global aviation network. Each of these missions must be carefully considered as the United States evaluates proposed regulatory changes at the international level, where they will inevitably impact the domestic use of America's airways. The challenge and the responsibility of the interagency process is to reconcile these diverse needs and translate them into a cohesive position that advances American innovation and resilience. This unified position will allow the United States to engage effectively with regional partners, build coalitions with allied nations, and advocate confidently for outcomes that protect the United States' interests. Those interests are substantial. The regulatory frameworks adopted at the conference will influence how the next generation of satellite constellations operate, influence the coexistence of emerging communications services, and influence how spectrum policy supports both economic growth and national security. That is why preparation for Work 27 is not a short-term exercise. Today's committee hearing examines how best to support the interagency in the coming months. We all share the goal of advancing U.S. leadership in spectrum and in space. Thank you, and I look forward to your testimonies. And now I recognize my friend, Ranking Member Liu Han, for your opening statement.
