Federated Wireless Advocates 4 GHz Band for 6G Development
Federated Wireless issued a position paper on August 14, 2025, advocating for prioritizing the 4.4–4.94 GHz band to facilitate 6G development in the United States. This paper discusses the strategic advantages of this frequency and its alignment with regulatory readiness, emphasizing its role in enhancing U.S. wireless capability.
Position and Urgency
The document, titled “Why the U.S. Must Prioritize the 4 GHz Band for 6G,” points out the importance of securing this spectrum amidst regulatory changes aimed at reallocating 500 Megahertz (MHz) for commercial purposes. This development is part of the broader objectives outlined in the bipartisan “Big Beautiful Bill.”
Insights from Leadership
According to Iyad Tarazi, CEO of Federated Wireless, the 4 GHz band represents a critical opportunity for the U.S. in the ongoing race to advance 6G technology. He noted that it offers a combination of technical readiness, international alignment, and favorable regulatory conditions essential for this next generation of wireless communication.
Comparison with Other Bands
The position paper contrasts the potential of the 4 GHz band to the heavily regulated 3 GHz band, which is encumbered with multiple service rules and legacy licenses. The authors suggest that the 4 GHz band allows for effective federal-commercial spectrum sharing while maintaining cybersecurity standards.
Key Benefits of the 4 GHz Band
Key highlights from the paper include the alignment of the 4.4–4.94 GHz band with global standards, its compatibility with existing 5G systems, and its potential to support advancements in Artificial Intelligence (AI) and other technologies for future networks. These elements are crucial as international discussions progress on wireless standards.
Support for Federal Agencies
Through its advocacy, Federated Wireless seeks to support federal agencies in executing responsibilities under new regulations without disrupting current successful frameworks like the Citizens Broadband Radio Service (CBRS). Kurt Schaubach, Chief Technology Officer of Federated Wireless, emphasized that 6G involves more than just increased speeds; it will also transform connectivity through AI, dynamic spectrum usage, and enhanced sensing capabilities.
This position paper underscores the importance of prioritizing the 4 GHz band to position the U.S. favorably in the advancement of 6G technology. The timely insights from this blog reflect a concise summary of the original position paper published by Federated Wireless.
