This fireside chat will explore the critical role of the United States in shaping the global spectrum landscape. We will discuss strategies to maintain U.S. spectrum leadership through the ongoing transition, the importance of effective preparation for WRC-27 under the new administration, and the evolution of U.S. international spectrum policy. The panel will also delve into the challenges of cross-border coordination, the need for international spectrum harmonization, and the impact of global technology standards on spectrum allocation and utilization. By fostering a deeper understanding of these issues, we aim to contribute to the development of a robust and sustainable global spectrum ecosystem.
