NTIA Report Finds Viable Options for Spectrum Sharing in 3450-3550 MHz Band
Spectrum sharing strategies hold great promise for meeting the growing needs of commercial and federal users. This is an area of intense study at NTIA as we seek to protect critical federal missions while enabling new commercial opportunities. As part of an assessment conducted with the Department of Defense, we are happy to announce significant progress in finding potential spectrum sharing options for the 3450-3550 MHz band, as outlined in a new technical report.
Federal operations in the 3450-3550 MHz band include shipborne, airborne, and land-based systems — primarily radars. Our report points to a clear possibility for real time spectrum sharing that would protect these critical missions, while providing attractive opportunities for commercial business. The report analyzes the potential for these federal systems to share spectrum with outdoor base stations, indoor access points, and mobile user equipment.
The report assesses two hypothetical commercial deployments, operating at various power levels, which industry has said would be desirable. The next step would be to study how often each of the federal systems actually is used, and then develop mechanisms for reliably informing commercial operations when federal systems are operating nearby.
