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.
