Optimizing the 4 GHz Band for America’s Economic and National Security

Commercializing the 4 GHz band (4.4-4.94 GHz) will be key to U.S. efforts to lead the world in wireless and next-generation AI innovation. The band sits in prime mid-band territory, can support the wide channels required for future advanced network capabilities, and is already aligned with existing global 5G and 6G standards and device ecosystems. As AI traffic spikes and 6G moves from concept to reality in coming years, the United States will need new large, contiguous blocks of full-power commercial spectrum. The 4 GHz band is a prime opportunity for the U.S. to lead in this next generation of wireless innovation, AI infrastructure, and investment, while preserving critical government missions.
