From Research to Operational Reality: Why Integrated Sensing and Communications Is Reaching an Inflection Point

Two years ago, I had the opportunity to lead an academic study ISAC Report 05-25 and a national workshop  sponsored by the Office of the Undersecretary of War for Research & Engineering,  Future G Wireless Office examining the future of Integrated Sensing and Communications (ISAC)—an emerging technology that combines wireless communications and sensing capabilities within a common infrastructure. These engagements brought together experts from government, academia, industry, and the defense community to explore a simple but important question:

What happens when wireless networks become more than communications systems?

At the time, ISAC was largely viewed as a future research topic associated with next-generation wireless technologies. Today, that perspective is changing rapidly. Around the world, governments, technology providers, and defense organizations are moving beyond theory and into experimentation, prototyping, and operational development.

The conversation is no longer about whether ISAC has potential. The conversation is about how quickly organizations can turn that potential into capability.

Historically, communications and sensing have been treated as separate functions.

Communications networks move information between people, devices, and systems. Radar and sensing systems detect, locate, and track objects. Positioning technologies provide location awareness. Each has traditionally operated within its own domain.

ISAC changes that model.

By combining communications and sensing within a shared infrastructure, future wireless networks can do more than connect users and devices. They can contribute to situational awareness, environmental understanding, object detection, positioning, and decision support.

This evolution has significant implications for both defense and critical infrastructure environments.

Future wireless architectures may help identify unauthorized drones near sensitive facilities. They may contribute to distributed awareness across large operational areas. They may support infrastructure monitoring, asset visibility, and enhanced operational insight in environments where traditional sensing systems alone may not provide sufficient coverage.

In many cases, the network itself becomes part of the sensing architecture.

That represents a fundamental shift in how we think about communications infrastructure and the value it can provide.

The strategic importance of ISAC extends well beyond technology innovation.

Many of the world’s leading research organizations and governments recognize that future wireless architectures will play a significant role in military modernization, autonomous systems, resilient communications, and multi-domain operations.

The challenge for the United States is not a lack of innovation. Our universities, laboratories, technology providers, and defense organizations continue to produce groundbreaking research.

The challenge is speed.

Globally, nations are investing heavily in next-generation wireless testbeds, sensing-enabled architectures, and operational experimentation. At the same time, the United States continues to navigate fragmented standards efforts, evolving architectures, and the complex process of transitioning emerging technologies into deployable capabilities.

That transition matters.

History repeatedly demonstrates that technological leadership is not determined solely by invention. It is determined by the ability to operationalize innovation, establish deployment models, develop skilled ecosystems, and create repeatable pathways from research to mission impact.

ISAC is approaching that moment.

The next phase of leadership will be defined by organizations that can accelerate implementation, experimentation, and operational learning.

When people discuss emerging technologies, the focus often centers on technical challenges. Those challenges are important, and ISAC certainly presents its share of them.

Researchers continue to advance capabilities involving signal processing, distributed sensing, edge computing, AI-enabled analytics, and data fusion. These innovations will remain critical to the future success of sensing-enabled communications systems.

At the same time, many of the most pressing challenges are no longer purely technical.

Organizations must determine how to evaluate ISAC capabilities in realistic environments. They must understand how sensing data can be integrated into operational workflows. They must establish architectures that support interoperability, scalability, security, and long-term evolution.

Most importantly, they need opportunities to test and learn.

History shows that breakthrough technologies rarely succeed because of research alone. They succeed because organizations create pathways that allow innovation to be evaluated, refined, and operationalized.

The next phase of ISAC development will be defined by experimentation and operational learning.

One lesson repeatedly reinforced throughout the broader ISAC community is that innovation accelerates when organizations can collaborate within open and flexible environments.

Future sensing-enabled communications systems will involve multiple technologies, multiple vendors, and multiple disciplines working together. Success will depend on interoperability as much as individual innovation.

Open architectures enable organizations to evaluate new capabilities without being constrained by rigid implementation models. They support experimentation, integration, and adaptation as technologies mature and requirements evolve.

This is particularly important in a field as dynamic as ISAC, where standards, operational concepts, and deployment approaches continue to develop.

The organizations that make the greatest progress will be those that embrace collaboration and build environments where ideas can be tested and improved rapidly.

As ISAC moves toward broader adoption, one reality is becoming increasingly clear: success will depend on more than technology.

Organizations need environments where communications infrastructure, sensing platforms, edge computing resources, software applications, and operational workflows can be evaluated together. They need opportunities to explore interoperability, validate performance, and understand how these capabilities function under real-world conditions.

This is where collaboration between government, academia, industry, and systems integrators becomes especially important.

Advancing ISAC will require more than new hardware and software. It will require practical experimentation, operational testing, and the ability to bring diverse technologies together into cohesive solutions.

The organizations that help bridge the gap between research and deployment will play a critical role in shaping the future of sensing-enabled communications.

The most important outcome of the national ISAC workshop was not a specific technical recommendation. It was the recognition that advancing these capabilities will require a coordinated effort across the entire ecosystem.

The next chapter of ISAC will not be written solely in research papers.

It will be written through experimentation, integration, prototyping, and operational learning.

The organizations that help bridge the gap between research and deployment will play a critical role in defining the future of communications, sensing, and mission awareness.

And that work is only beginning.
