Spectrum efficiency is increasingly vital as defense and commercial wireless demands converge in shared bands. At Key Bridge Wireless LLC, we recently concluded two productive monthly collaboration meetings in April 2023 for Project NSC-20-2093, providing comprehensive reviews of Phase 2 advancements under the DoD's "5G – Next G" program.
The sessions on April 5 and April 27 brought together key stakeholders from AFRL, NIWC Atlantic, NSWC Crane, MITRE, DCMA, Nokia, and other partners. Discussions covered integrated schedules, deliverable tracking, risk management, standardization efforts, and detailed technical updates. Presentations highlighted the maturation of our Spectrum Coexistence and Sharing (SCS) system, with particular emphasis on field demonstration results.
Attendees reviewed successful deployments of our adapted ESC sensors detecting airborne radar signals in the 3.1-3.45 GHz band, advanced ML-driven detection algorithms performing robustly in noisy environments, and seamless SAS integration dynamically controlling Nokia's 5G RAN for real-time spectrum decisions. Feedback was positive, with constructive questions on performance metrics and future standardization contributing to refined action items.
The collaborative atmosphere—no major blockers reported—and clear progress toward full system functionality underscore the strength of this government-industry partnership. These meetings validated that all core aspects of the Key Bridge solution have now been demonstrated in operational scenarios at Hill AFB and UTTR.
I want to personally thank NTIA-ITS, the Air Force, the dedicated team at Hill AFB, and the project principals for their exceptional support and collaboration throughout Phase 2. Their expertise and commitment were instrumental in the success of these field trials.
This achievement reinforces our dedication to technologies that enhance national security and spectrum utilization.
