Verizon and T-Mobile have filed for FCC experimental authorizations to test the 4.8-4.9 GHz spectrum band for potential 6G use cases. These tests, involving hardware from Ericsson and Samsung, follow recent NTIA initiatives to study the 4.4 GHz band for future commercial licensed use.
The move into the 4.8-4.9 GHz range signals a shift in network architecture as operators identify mid-band frequencies capable of supporting 6G throughput. For the streaming ecosystem, this transition is critical for maintaining high-bitrate mobile video delivery as 5G networks reach capacity. While the CTIA argues for exclusive licensing, the involvement of cable giants like Comcast and Charter through the Spectrum for the Future group suggests a looming battle over shared versus exclusive access. Industry observers should watch for the NTIA study results to see if federal incumbents are relocated or if a shared-access model becomes the regulatory standard for this band.
Verizon and T-Mobile have requested FCC authorization to test the 4.8-4.9 GHz spectrum band for future 6G applications. This development is significant as operators seek mid-band frequencies to maintain high-bitrate mobile video delivery. The trials, utilizing Ericsson and Samsung hardware, highlight a growing industry debate over exclusive versus shared-access licensing models.
The operators are testing the 4.8-4.9 GHz band to evaluate its potential for supporting future 6G high-capacity wireless performance and to address the need for more bandwidth as 5G networks reach capacity.
Verizon and T-Mobile are utilizing radio hardware from Ericsson and Samsung to conduct their experimental tests in non-commercial environments.
The primary challenge involves federal incumbents, such as the Department of Defense, currently using the band for radar and satellite systems. The NTIA is studying these systems to determine if they require relocation or if a shared-access framework can be implemented.
The CTIA advocates for exclusive licensed rules to encourage carrier investment, while the Spectrum for the Future coalition, backed by Comcast and Charter, supports a shared-access model to allow cable operators and new entrants access without expensive auction rights.
