Specifically, Huawei has many invention patents in millimeter wave signal transmission system, such as "millimeter wave signal transmission system and transmission device" and "a millimeter wave band beamforming method and device". In addition, Huawei also cooperates with many domestic and foreign enterprises and scientific research institutions to promote the development and application of millimeter wave technology.
In addition to Huawei, other companies and institutions have also made some important patent achievements in millimeter wave technology. For example, the Advanced Research Projects Agency (DARPA) of the US Department of Defense launched a research project called "Millimeter Wave Radar Sensor" in 1990s, and successfully developed a millimeter wave radar system that can detect stealth targets. In addition, some universities and research institutions in the United States, Europe and Japan have also made some important research achievements in millimeter wave technology.
To sum up, millimeter wave communication technology is a complex system technology, involving many patents and inventions, and many companies and scientific research institutions have carried out research and innovation in this area. Huawei has many invention patents in millimeter wave technology, and cooperates with many domestic and foreign enterprises and institutions to promote the development and application of millimeter wave technology.
