The closing of the World Radiocommunication Conference 2019
On November 22, the four-week high-profile World Radiocommunication Conference 2019 (WRC-19) ended in Sharm el-Sheikh, Egypt. Nearly 4,000 participants from ITU's 193 Member States, 900 Sector Members, and international organizations, equipment manufacturers, telecommunications operators, and industry organizations attended the meeting, the highest in history. At the closing ceremony, Xie Yuansheng, deputy head of the Chinese delegation and director of the Radio Management Bureau of the Ministry of Industry and Information Technology, authorized the signing of the ITU Final Act on Radio Regulations (WRC-19) on behalf of the Chinese authorities. Provisional Final Acts).
As the most important international conference on the signing of legislation on the use of global radio frequency spectrum and satellite orbit resources, the 2019 World Radiocommunication Conference on the allocation of 5G millimeter wave frequency bands and terahertz ground communication frequency bands, and newly-used frequency bands for high-altitude platform communications (HAPS), railways Coordinate with the global frequency use of traffic and radio communications, new frequencies for global maritime, aviation distress and safety systems, revision of the rules for the use of low-orbit constellation satellites, short-lived satellite frequencies and orbit resources, and technical requirements for coexistence of non-geostationary systems for geostationary orbit systems And when the terrestrial radio service is allocated or designated to use the frequency band, it has reached consensus on important issues such as the protection of existing satellite mobile services, satellite meteorological services, satellite earth exploration services, and satellite sound broadcasting services on adjacent frequencies. The results will affect the future ten to In the past two decades, the world's multi-trillion-dollar radio technologies, applications, and integration and development with related industries have played an important role in the United Nations' sustainable development goals such as advancing the digital economy and reducing the digital divide.
Among them, the conference will use the 14.75GHz band of 24.25 GHz ~ 27.5 GHz, 37 GHz ~ 43.5 GHz, 66 GHz ~ 71 GHz for 5G and future international mobile communication systems worldwide. At the same time, measures will be taken to fully protect the same frequency band Inter-satellite services, fixed-satellite services, etc., as well as satellite earth exploration and radio astronomy passive services in adjacent frequency bands. The conference established non-geostationary constellation systems based on international regulatory frameworks such as “milestones” that must meet a certain percentage of the number of satellites in orbit in a certain period of time, and 50 / 40GHz band non-geostationary satellite frequency sharing consultation mechanism, and opened a low-orbit satellite constellation A new era of development. The conference passed a resolution on the global uniform frequency of railway car-ground wireless communication systems, which will promote the development of wireless communications in the control and scheduling of high-speed railways worldwide and passenger safety, and promote relevant countries, especially developing countries, to strengthen cooperation in cross-border railway transportation. Opening up the “Belt and Road” cross-border transportation artery has created favorable conditions. The conference approved a new proposal for a globally unified frequency band for intelligent transportation systems, which will further promote the coordinated development of the International Intelligent Networked Vehicle (IoV). The conference clarified that the spectrum resources with a total bandwidth of 137GHz in the 275GHz ~ 450GHz band can be used for fixed and land mobile service applications, and provided a clear spectrum policy guide for the terahertz communication industry. In addition, this conference also added frequency allocations or designated frequency bands for high-altitude platforms (HAPS), Ka-band mobile earth stations, 51GHz fixed-satellite service (Earth-to-space), satellite aeronautical mobile services, and microsatellite measurement and control. The relevant rules for the introduction of satellite systems in the aviation and maritime bands, unauthorized use of earth station terminals, etc. were amended, and the frequencies for the global uniform use of wireless charging of electric vehicles were determined ... The results of these conferences will come into effect in the form of international treaties, which will be effective for China Radio technology and applications in various fields such as communications, civil aviation, transportation, radio and television, meteorology, aviation, and aerospace, and the integration and development of related industries have an important impact.
The conference also identified the topics to be considered in the World Radiocommunication Conferences in 2023 and 2027. The topic of adding the IMT logo in the 6GHz mid-frequency band promoted by China was included in the 2023 agenda.
During the meeting, the Chinese delegation actively carried out international exchanges with the radio administrations of ITU, the United States, Russia, the United Kingdom, Germany, France, Switzerland, Japan, South Korea, Indonesia, Brazil, Colombia, Mexico, Algeria, and the United Arab Emirates The major regional organizations, BRICS countries and related equipment manufacturers have conducted dozens of delegation-level bilateral and multilateral exchanges, fully elaborated China's position and concerns, and sought broad support from all parties and more diverse positions. Understanding more and achieving good results has laid a solid foundation for the successful completion of the participation tasks. During the nearly one-month meeting, members of our delegation fully and deeply participated in the research and discussion of various issues. They actively spoke at the meeting and actively carried out exchanges under the meeting. After participating in various tasks, it demonstrated a high sense of national mission, honor and political responsibility.
