RTX Corporation's BBN Technologies has announced a collaborative research initiative aimed at ensuring secure, real-time spectrum coexistence between defense radars and commercial 5G networks in the 3.1 to 3.45 GHz band. The project, conducted in partnership with the Department of War and the National Spectrum Consortium, brings together multiple industry and academic partners to develop a prototype system that protects critical national security radars while enabling expanded commercial 5G use. The team aims to achieve a 50% increase in usable 5G capacity, a 20 dB reduction in radar interference, and a 1,000-fold improvement in 5G link quality. The results and system integration are part of ongoing work and will be presented in the future.
