Federated Wireless Releases Position Paper Advocating 4 GHz Band as Path to 6G Leadership

Federated Wireless published a position paper on August 14, 2025, advocating for the prioritization of the 4.4–4.94 GHz band to support the development of 6G in the United States. The paper outlines strategic benefits, accessibility to spectrum, and readiness for regulatory frameworks, positioning this frequency as a crucial element for U.S. wireless leadership.

Entitled “Why the U.S. Must Prioritize the 4 GHz Band for 6G,” the document emphasizes the urgency of capitalizing on this spectrum amid federal efforts to implement new legislation requiring the reallocation of 500 Megahertz (MHz) for commercial use. This initiative aligns with the goals set by the bipartisan “Big Beautiful Bill.”

“If 6G is the wireless industry’s current version of the space race, the 4 GHz band is our Saturn V,” said Iyad Tarazi, CEO of Federated Wireless. He noted that this band represents a unique combination of technical readiness, global alignment, and regulatory conditions necessary to advance 6G implementation in the U.S.

The paper also contrasts the 4 GHz band with the heavily regulated 3 GHz band, which poses significant challenges due to its division among multiple service rules and legacy licenses. The 4 GHz band is considered more favorable, hosting well-defined systems that allow for manageable federal-commercial sharing while maintaining national security.

Key points from the paper include: the 4.4–4.94 GHz band’s alignment with global standards; its compatibility with existing 5G systems; the feasibility of coexistence with federal users; and the potential to support advancements in AI-driven technology for next-generation networks. The authors stress the importance of adopting this band to enable swift progress in wireless standards as international discussions advance.

By advocating for the 4 GHz band, Federated Wireless aims to assist federal agencies in fulfilling their responsibilities under the new directive without complicating existing success models, such as Citizens Broadband Radio Service (CBRS). Kurt Schaubach, CTO of Federated Wireless, added, “6G isn’t just about faster networks—it’s about redefining connectivity through AI, sensing, and dynamic spectrum use.”
