FirstWave is an innovative XR Simulator Platform designed to enhance public safety coordination at large-scale events. By integrating with ATAK/CivTAK systems, FirstWave offers a realistic extended reality (XR) training environment where event organizers, first responders, and security teams can simulate scenarios, test responses, and refine operations in a risk-free setting. Functioning as a “game engine” for public safety, FirstWave enables teams to practice real-time communication, situational awareness, and crisis response using geospatial mapping and real-world data. Its marketplace allows vendors to contribute customized plugins, offering users a tailored training experience with specialized tools and assets. This adaptive, immersive approach equips teams to manage emergencies with increased efficiency and preparedness, leading to safer events. NimbusXR’s FirstWave platform fills a critical gap in training and planning, providing a transformative solution for modern event coordination.
