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.

As the world begins to get out of the shadow of COVID-19, the continuous improvement of 5G penetration is becoming an important driving force for global economic growth. According to the prediction of GSMA, from 2021 to 2025, the capital expenditure of global mobile operators will reach US $900 billion, of which 80% will be used for 5g business; By the end of 2025, the number of 5g mobile connections will account for one fifth of the global total, close to 2 billion. China will also continue to lead the world, with the largest number of users in the world (more than 830 million), and the total number of 5g connections will also exceed 800 million. 90% of the $210 billion capital expenditure of operators will be used for 5g.

Si Han, President of GSMA Greater China, pointed out in his speech at the second 5g millimeter wave industry summit forum that the distribution of millimeter wave spectrum is an important node on the road of 5g development. For the Asia Pacific region and the global market, 5g, as a new economic growth point, will further promote the development of digital economy. It is expected that the Chinese government and industry will further promote the millimeter wave spectrum planning and layout in advance as soon as possible.

She said that driven by the 5g application "sailing" action plan (2021-2023), China will soon usher in a hundred flowers bloom and large-scale mature development of 5g applications in consumers and industries.

According to the latest data from the Ministry of industry and information technology, as of August this year, China has built a total of 1.037 million 5g base stations, accounting for more than 70% of the world; 5g end users exceeded 400 million, making it the largest user group in the world; From January to August this year, domestic shipments of 5g mobile phones reached 168 million, a year-on-year increase of 80%; There are more than 10000 5g application cases, "5g + industrial Internet" has become one of the most active fields of application innovation, covering 22 important industries such as electronic equipment manufacturing, steel, electric power and mining.

"If the first half of 5g is a table tennis game that reflects the single player technology of telecom operators, then in the second half, 5g will become a football game with different roles and participation of vertical industries." Wen Ku, vice president and Secretary General of China Communications Standardization Association, said that although China has played well in table tennis, it is difficult to play football. It is hoped that the industrial chain will cooperate to play both table tennis and football well. At the same time, "only by doing 5g well can we do 6G well". The development of millimeter wave needs to strengthen industry university research cooperation, jointly promote the maturity of millimeter wave industry, and accumulate experience for the possible use of 6G terahertz in the future.
