CTIA Pushes for 4 GHz Band Study to Secure U.S. Wireless and AI Leadership — CTIA

Event summary

CTIA report identifies 4 GHz band as critical for U.S. wireless and AI leadership, recommending an NTIA study within 60 days.
U.S. networks projected to need 820 MHz of additional mid-band spectrum by 2028, with $1.4 trillion in economic growth at risk without it.
4 GHz band offers 400 MHz of contiguous spectrum aligned with 5G/6G standards and supported by 1,500 compatible devices.
China's push for 6 GHz licensed use creates strategic urgency for U.S. to advance 4 GHz band before WRC-27.

The big picture

The push for 4 GHz spectrum comes as AI-driven demand for wireless capacity surges, threatening to outpace available mid-band spectrum. With China actively shaping global spectrum standards, the U.S. faces strategic pressure to secure its leadership position in 6G and AI infrastructure. The 4 GHz band represents a critical opportunity to align domestic spectrum policy with emerging technological needs while maintaining competitive advantage.
