All countries in the world have started the construction of 5G networks. The first few network eras were dominated by Western countries, but with 5G, China has begun to rise. With Huawei's long-term efforts, China's 5G network construction is in a leading position in the world.

　　Every year, Huawei invests a lot of research and development expenses in the research and development of 5G networks. As early as ten years ago, Huawei established a 5G research laboratory. In the ten-year layout, Huawei has achieved great success.

　　It has the world's largest number of 5G patented technologies and is an important participant in the formulation of 5G network standards. When the 5G era arrives, the advantages of Huawei's 5G will further increase.

　　Anyone who knows Huawei 5G knows that Huawei has a great advantage in the field of centimeter wave technology. The 5G equipment purchased by domestic operators basically adopts Huawei's 5G centimeter wave technology. With wide coverage and strong signal, with the popularity of Huawei, centimeter wave may become the mainstream frequency band in the 5G era.

　　But in fact, millimeter wave also has great advantages. The United States has been deploying millimeter waves, and American operators are also promoting millimeter wave technology. From a technical point of view, millimeter wave also has great potential, and if applied properly, it can accelerate the layout of the 5G industry.

　　The good news is that Huawei has made another contribution. It is reported that with the cooperation of Huawei and industry partners, the world's first 5G high- and low-frequency CA carrier aggregation technology laboratory test has been completed, and the single-user download rate has reached 5.2Gbps. After a breakthrough, this carrier aggregation technology can achieve better commercial use in the high and low frequency bands of millimeter waves.

　　Huawei's technical verification can provide users with a continuous high-speed 5G experience, and it belongs to the mainstream technology application field in terms of 5G high-frequency and low-frequency collaboration.

　　Under Huawei's layout, China's millimeter-wave technology ushered in an "ice-breaking". It also proves that Huawei not only has a leading edge in the field of centimeter wave technology, but also can participate in the important deployment of 5G millimeter wave technology. In the future, when Huawei participates in 5G network competition in countries around the world, it can customize corresponding 5G network solutions according to different market environments.

　　According to different application scenarios, the advantages of millimeter wave and centimeter wave are also different. The advantages of millimeter-wave and centimeter-wave technology can only be maximized by distribution on demand.

　　From the perspective of the coverage of 5G network, centimeter wave is the best choice. If it is in a certain venue or a specific area, using millimeter waves can bring a better transmission experience. Even 8K video can be transmitted in real time.

　　Huawei has made important contributions to the development of China's 5G network. Both centimeter-wave and millimeter-wave have made major technological breakthroughs, providing more possibilities and feasibility for my country to carry out 5G construction.

　　According to statistics, as of the end of August, 993,000 5G base stations have been opened and built in my country, and all prefecture-level areas in China have achieved 5G network coverage. 5G terminal connection users also reached about 400 million.

　　In addition, before the end of this year, 5G news is expected to be commercialized, and at that time, 5G scenarios will be promoted and the economic benefits of the 5G market will be optimized.
