DOD Issues First Requests for Prototype Proposal Through the National Spectrum Consortium's Spectrum Forward OTA The RPPs, which focus on Risk-Informed Spectrum Access and Multiband Control Channel Architecture, are open to members of the National Spectrum Consortium (NSC) News provided by Share this article Share this article WASHINGTON, April 15, 2021 /PRNewswire/ -- The US Department of Defense (DOD) has issued two Requests for Prototype Proposal (RPPs) in support of electromagnetic spectrum research related to the capabilities of the 400+ members of the National Spectrum Consortium. The Risk-Informed Spectrum Access (RISA) RPP calls for industry input to develop and demonstrate a set of prototype spectrum access planning, management and operational tools. These tools will provide the capability to identify, assess and reduce systemic risk to mission associated with current or projected spectrum availability to assist with both planning and during operations. The tools will have the potential to be employed in legacy systems as well as infrastructure-based (e.g., DoD test and training ranges) and infrastructure-free (e.g., tactical edge) spectrum access systems.
