In October 2019, GIRD successfully demonstrated a novel waveform with a prototype software defined radio (SDR) platform on their Phase II SBIR program with the Army to provide reliable communications from within a deep jungle canopy. The deep jungle canopy forms a natural radio frequency barrier blocking transmissions both into and out of the jungle canopy. GIRD successfully established and maintained links at distances over 35 mi with extremely low signal-to-noise ratios (SNRs).
