Key Bridge Awarded Patent for Spectrum Sensing Capability Enabling CBRS ESC
McLean, VA – Key Bridge Global LLC today announced that the United States Patent and Trademark Office has awarded the company U.S. Patent No. 9,357,395 for a novel spectrum sensing technology that protects non-informing transmitters from interference.
The patent, issued to CEO Jesse Caulfield, covers critical methods for detecting and mitigating interference to incumbent systems—such as U.S. Navy radar operations—that do not broadcast identification signals. This innovation is foundational to Environmental Sensing Capability (ESC) systems proposed for the FCC’s 3.5 GHz Citizens Broadband Radio Service (CBRS) band, enabling dynamic spectrum sharing while ensuring zero interference to federal incumbents.
Key Bridge’s patented approach supports real-time spectrum awareness and protection, aligning with ongoing FCC proceedings (GN Docket No. 15-319) and standards development by the Wireless Innovation Forum. As a leader in spectrum administration, including TV White Spaces and Defense contracts, Key Bridge continues to advance technologies that make shared spectrum viable for commercial wireless innovation.
“This patent underscores our commitment to solving the toughest challenges in dynamic spectrum access,” said Jesse Caulfield, CEO of Key Bridge Global LLC. “By protecting non-informing incumbents like naval radars, our technology paves the way for robust ESC deployment in CBRS, balancing federal protections with expanded access for enterprises and carriers.”
Key Bridge’s spectrum management platforms are operational nationwide, supporting FCC-certified services and preparing for CBRS commercialization.
