Key Bridge Wireless LLC Successfully Demonstrates Phase 2 of DoD Dynamic Spectrum Sharing 5G Prototype

McLean, VA – May 1, 2023 – Key Bridge Wireless LLC, a leader in advanced spectrum management and dynamic sharing technologies, announces the successful completion and demonstration of all Phase 2 objectives for Project NSC-20-2093, the Dynamic Spectrum Sharing 5G Applications Prototype, under the National Spectrum Consortium (NSC) and the Department of Defense (DoD).

Phase 2 emphasized functionality, maturation, and real-world field demonstrations of the Spectrum Coexistence and Sharing (SCS) system, enabling airborne radar systems and 5G cellular networks to operate without interference in the 3.1-3.45 GHz band. Key Bridge's solution has now been fully demonstrated across laboratory and field environments at Hill Air Force Base and the Utah Test and Training Range.

Major accomplishments include:

Full deployment and operation of an adapted Environmental Sensing Capability (ESC) network in the 3.1 GHz band, reliably detecting high-power airborne radar emissions, including simulated AWACS platforms.
Advanced machine learning models trained for precise radar pulse detection and classification, achieving high accuracy in dynamic scenarios with concurrent 5G signals.
Real-time integration of Key Bridge's Spectrum Access System (SAS) as a scheduler controlling a commercial Nokia 5G Radio Access Network (RAN), dynamically managing spectrum access to protect incumbent radar operations while maximizing 5G throughput.
Comprehensive field testing validating detect-and-avoid mechanisms, interference mitigation, and system performance under operational conditions.

These demonstrations, reviewed in collaboration meetings throughout April 2023, confirm the technical feasibility and military utility of Key Bridge's SCS prototype, advancing from laboratory validation to mature field performance.

"This successful Phase 2 demonstration represents a major milestone in dynamic spectrum sharing for defense applications," said Jesse Caulfield, CEO of Key Bridge Wireless LLC. "By proving our ESC and SAS technologies in real-world 5G integration with Nokia's RAN, we have shown a scalable path to efficient coexistence that preserves critical radar capabilities while enabling advanced 5G networks."

The project supports the DoD's "5G – Next G" initiative and positions the SCS system for Phase 3 stability enhancements and pre-production integration.
