7 terms

5g technical

"when they share the same radio frequencies with commercial 5G networks."

5G is the fifth generation of wireless technology that provides faster internet connections, lower latency, and greater capacity than previous networks. It enables quicker downloads, smoother streaming, and more reliable connections for devices. For investors, 5G represents a significant upgrade in technology infrastructure that can drive growth in related industries such as smartphones, smart cities, and the Internet of Things.

spectrum coexistence technical

"This initiative addresses concerns about maintaining the operational readiness of critical national security radars when they share the same radio frequencies with commercial 5G networks."

Spectrum coexistence is the practice of different wireless services and devices using the same radio frequencies at the same time without causing harmful interference to each other. For investors, it matters because successful coexistence can lower costs, speed market rollouts and enable more services from the same resource, while poor coexistence risks regulatory limits, expensive network upgrades or lost revenue—think of multiple neighbors sharing a driveway without blocking each other.

smart spectrum manager technical

"the BBN-led team will create a basic "smart spectrum manager" that can detect when a radar is operating"

A smart spectrum manager is a software-driven system that monitors and controls the use of radio frequencies to make wireless networks run more efficiently and avoid interference. Like a traffic controller or smart thermostat for airwaves, it dynamically assigns channels, enforces rules, and adapts to demand so network operators can carry more data, cut costs, meet regulator requirements, and unlock new services — outcomes investors watch for revenue growth and reduced operational risk.

dynamic spectrum management technical

"Federated Wireless will bring dynamic spectrum management capabilities to optimize shared spectrum usage."

A way of allocating radio frequencies so wireless services can share and use them more efficiently in real time, similar to letting cars switch lanes dynamically to avoid jams. For investors, it matters because better spectrum use can boost network capacity, reduce operating costs, and enable new services or customers without buying more frequency rights, which can change revenue growth, capital needs and regulatory risk for telecom and wireless-dependent companies.

machine learning technical

"Purdue University will deliver advanced signal processing and machine learning (ML) models for faster interference predictions."

Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.

View in glossary

spectrum sensing technical

"Novowi will offer ML-based techniques for real-time spectrum sensing, classification and localization"

Spectrum sensing is the process of detecting which radio frequency channels are currently in use and which are free so wireless devices can choose where to transmit without causing interference. For investors, it matters because effective spectrum sensing lets products use limited airwaves more efficiently, helps meet regulatory rules, reduces service problems, and can unlock new markets or cost savings for companies in telecom, IoT, and defense — like checking highway lanes before merging.

spectrum access system technical

"the team will also deliver a "sandbox" version of the spectrum access system that can run in the cloud"

A spectrum access system is an automated regulator for radio frequencies that assigns who can use which airwaves, when, and at what power to prevent interference between users. Think of it as an air-traffic controller for wireless signals: it coordinates access so higher-priority users are protected while others can use leftover capacity. Investors care because SAS performance and rules affect network reliability, capacity, potential revenue streams, and regulatory risk for companies relying on wireless spectrum.

Team to build prototype that protects defense radars when the 3.1 to 3.45 GHz band is opened for commercial use

CAMBRIDGE, Mass., Feb. 10, 2026 /PRNewswire/ -- RTX's (NYSE: RTX) BBN Technologies has been awarded a contract by the Department of War (DoW), in partnership with the National Spectrum Consortium, to support its Advanced Spectrum Coexistence Demonstration program. This initiative addresses concerns about maintaining the operational readiness of critical national security radars when they share the same radio frequencies with commercial 5G networks.

Current spectrum coexistence tools can take tens of minutes to detect interference, negotiate a new allocation, and reconfigure radios. This delay leaves both commercial 5G users and incumbent radars vulnerable to service loss or unsafe operations. In the program's first phase, the BBN-led team will create a basic "smart spectrum manager" that can detect when a radar is operating and predict whether a 5G signal might interfere and automatically shift 5G traffic to avoid issues in seconds.

In the second phase, the project will evolve from a basic working model to a more advanced prototype equipped with cutting-edge tools to ensure radar and 5G networks can share the same frequencies reliably and seamlessly. These tools will transform the system into a smart, self-managing platform that follows preset rules to automatically optimize spectrum sharing. Once developed, this platform can be deployed on operational radars and 5G systems, allowing them to work safely, securely, and efficiently side by side, with little need for human involvement.

"Lives are put at risk when a radar misses a target, whether it's a ship navigating waters or a rescue team tracking a storm," said Chris Vander Valk, BBN principal investigator for the effort. "Our work ensures those radars stay reliable, even as 5G frequencies become increasingly congested, so public and private shared use of the spectrum is optimized for all users."

The multi-team effort brings together the expertise needed for a comprehensive solution:

• Raytheon Advanced Technology will provide real radar signals and test equipment.
• Ericsson Federal Technologies Group will contribute 5G network expertise to ensure feasibility of transition.
• Signal Processing Technologies will share advanced interference cancellation, detection and localization techniques.
• Federated Wireless will bring dynamic spectrum management capabilities to optimize shared spectrum usage.
• Purdue University will deliver advanced signal processing and machine learning (ML) models for faster interference predictions.
• Novowi will offer ML-based techniques for real-time spectrum sensing, classification and localization, as well as security analysis.

BBN will integrate these components into a system for future government use and will incorporate a risk management function to balance potential impacts on incumbent and commercial operations.

The team hopes to achieve a 50% increase in usable commercial 5G capacity, a 20 dB drop in unwanted interference to radars, and a 1,000-fold improvement in 5G link quality when both systems operate side by side. To accelerate the transition, the team will also deliver a "sandbox" version of the spectrum access system that can run in the cloud or at the edge of the network, simplifying the move from testing to real-world deployment.

If successful, the system will turn a longstanding "either/or" dilemma—protect the radar or grow 5G—into a "both/and" solution, expanding the nation's digital economy while preserving national security. Work will be performed in Cambridge, Massachusetts; Marlborough, Massachusetts; Plano, Texas; Vienna, Virginia; Merrimack, New Hampshire; Arlington, Virginia; West Lafayette, Indiana; and Brookline, Massachusetts.
