The Department of Defense, through the U.S. Army Contracting Command, is seeking proposals for the Advanced Dynamic Spectrum Sharing Demonstration (ADSSD) as part of a collaborative effort with the National Spectrum Consortium (NSC). The objective of this initiative is to develop and demonstrate innovative spectrum-sharing technologies that will enable coexistence within the 3100-3450 MHz band while adhering to specific conditions outlined in the Emerging Mid-Band Radar Spectrum Sharing Feasibility Assessment Report. This project is critical for enhancing national defense capabilities and addressing the increasing competition for spectrum access, which is vital for both military and commercial operations. Interested parties must be members of the NSC to submit proposals, with a deadline for submissions set for February 28, 2025, and questions due by January 31, 2025.
