5g millimeter wave has many outstanding advantages, such as large frequency broadband capacity, easy combination with beamforming and ultra-low delay, which is conducive to promoting the development of industrial Internet, AR / VR, cloud games, real-time computing and other industries. At the same time, millimeter wave can support the deployment of dense areas, carry out high-precision positioning and high equipment integration, which will help to promote the miniaturization of base stations and terminals.

China's communications satellite industry has developed for nearly 50 years since China successfully launched its first man-made earth satellite, dongfanghong-1, in April 1970.

As a kind of radio wave, the millimeter wave in the past was not remarkable. The microwave transmission distance with lower frequency was far away, and it made great achievements in the field of communication. The light wave with higher frequency was also widely used in digital, communication and other fields. Only the millimeter wave in the middle was ignored.
