 This series of equipments latest developed by our company measure up the new digital microwave transmission system proposed by ITU. Using the latest COFDM modulating and error checking technology, they can effectively solve the problems of multipath interference, NLOS path and fast movement that are always met in the process of traditional microwave transmission. They can guarantee high-quality transmission effects, through the complex transmission paths of the lake water net regions, snow conditions and cities of high-rises etc or on the platforms of high-speed vehicles, ships, helicopters / UAVs and so on.
