Product Description: sf-m8801k2w series COFDM mobile wireless image real-time transmission system is a buckle type wireless video transmitter produced by our company. The COFDM modulation technology, which is the leading modulation technology at present, has relatively narrow air bandwidth (2MHz) and strong anti multipath interference ability. It overcomes the difficulties caused by multipath reflection and occlusion in image transmission under simulation technology and conventional modulation technology, and realizes shooting and real-time non line of sight transmission of high-quality images in high-speed motion, which is especially suitable for complex environment. This series of products are equipped with radio and television standard bayonet on the panel, which is suitable for TV broadcasting, news gathering and other fields.
