What will first responders of the future look like? Ten years from now, how will responders communicate, receive situational information, sense hazards, and protect themselves? The Responder Technology Alliance (RTA) not only seeks to answer these questions, but also works to turn the answers into practical real-world tools. Established by the First Responders Group within the Department of Homeland Security Science and Technology Directorate, the RTA brings together responders, industry, federal agencies, research institutions, investors, and academia to focus on the most difficult technology challenges along the road to the Responder of the Future.
