Communications Systems

Reliable, resilient, and secure communications in any environment

Effective communications systems and networks are of vital importance to government, military, and commercial operations. Timely and reliable access to information enables decisive and informed action.

Johns Hopkins APL develops reliable, resilient, and secure communications technologies and systems for use in any environment. We apply our expertise in systems engineering, evaluation, and prototyping to address critical needs—from secure end-to-end networks in combat systems to mobile situational awareness tools for first responders.

Our work spans the communications spectrum—including radio frequency and microwave communications, satellite communication, laser communications, and wireless technology—and our status as a university affiliated research center allows our researchers to bridge the gap between available commercial communications technologies and the unique operational and tactical needs of our sponsors to deliver new secure capabilities and ensure the reliability and security of existing secure communication architectures.

On the battlefield, soldiers are constantly moving around and need to communicate with one another…they need the right information at the right time. Providing the right quality of service and end-user experience is important.
