The Department of Defense, specifically the Army's ACC-APG office, is conducting a Request for Information (RFI) regarding Software Defined Radio (SDR) hardware and waveform capabilities for line-of-sight communications. The objective is to gather market research on SDR solutions that can support multiple channels and meet specific technical requirements, including size, ruggedization, and compatibility with existing terrestrial waveforms. This initiative is crucial for enhancing communication pathways in military operations. Interested vendors are encouraged to submit technical white papers and capability overviews electronically to the designated Contracting Officers by the deadline, which is 30 days from the publication date of this notice.
