UWB technology, which originated in the 1960s, is a wide spectrum, nanosecond-level electromagnetic wave that is safe and reliable. When used in active safety solutions, the system responds quickly and is easy to pass through obstacles, making it a comprehensive solution. The Litu pedestrian collision avoidance system utilizes UWB radio wave technology to form a controllable safety zone between forklifts and pedestrians, as well as between forklifts themselves, typically in the form of a circle with the base station as the center.
