APEX1644 Compact COFDM Wireless Video Transmitter

The APEX1644 is a compact COFDM wireless video transmitter designed specifically for UGV/Robotics video transmission and ground surveillance applications. It supports analog (AV) video input. It uses high-tech COFDM modulation technology and H.264 encoding technology, which are designed for covert and mobile operations. It has good characteristics of far range transmission, small size, light weight, low power consumption, high speed movement, etc. It is mainly used for NLOS wireless video transmission under complex electromagnetic environment, such as UGV/Robotics: the real-time video transmission will be achieved at long-range in a complex environment.
