In this episode of Cache Me if You Can, we examine the invisible infrastructure that powers our digital lives: spectrum and telecommunications networks.

Our guest, Diane Rinaldo, former Acting Administrator of NTIA and a leading expert on 5G and supply chain security, breaks down the strategic stakes of next-generation wireless systems. We explore how spectrum competition shapes U.S.–China tech rivalry, why trusted networks are central to national security, and how emerging technologies like AI and quantum are transforming the telecom landscape.

Finally, we look ahead to 6G and discuss what the United States must do now to stay competitive in the race for the future of connectivity.
