CTOnews.com February 13 news, according to the Ministry of Industry and Information Technology, today is the 12th "World Radio Day" (World Radio Day), the theme is "Radio and Peace" (Radio and Peace).

On February 13, Pexels1946, United Nations Radio was established and broadcast to the world by radio waves. In order to commemorate the establishment of United Nations Radio, on November 3, 2011, UNESCO decided to designate February 13 of each year as "World Radio Day" to promote radio as a carrier of broadcasting and communication. it plays an important role in promoting the development of education, the dissemination of information and the dissemination of major information in natural disasters, and to strengthen people's attention to the unique value of radio.

According to the Ministry of Industry and Information Technology, radio spectrum is a strategic, basic and leading resource in today's information society. Radio spectrum contains great economic value and social value. Just as the construction of high-rise buildings is inseparable from land resources, the development of any radio service must be based on spectrum resources. CTOnews.com has learned that all 42 radio services defined by the International Telecommunication Union have been widely used in China. Radio is like a ubiquitous neural network, it plays a key role in many fields, such as public communication, radio and television, aerospace, transportation, weather prediction, satellite navigation, radio astronomy, scientific research, public security, national defense and military, and so on. It is profoundly changing people's production and life.

Radio empowers digital economy and accelerates industrial integration. Today, with the acceleration of the information process, the application of radio technology is effectively promoting the development of digital economy and industrial integration. Relying on 5G, wireless access communications (wireless local area network), wireless data, radio frequency identification, Bluetooth and other wireless communication technologies, the industrial scale of China's industrial Internet and Internet of things has broken through the trillion mark and has been widely used in 45 major categories of national economy. It makes it possible to make "smart building in China" possible, accelerate the construction of smart cities and digital villages, and make electricity and medical care have wisdom. It has injected new momentum into industrial transformation and upgrading and high-quality economic and social development. Relying on the vehicle network constructed by the wireless direct connection communication system of 5.9GHz special frequency band and millimeter wave car radar, the information exchange among cars, roads and people is realized, and intelligent transportation and even self-driving come to you and me. At present, vehicle networking has become an important infrastructure of China's digital economy. 13 provinces (autonomous regions and municipalities) have obtained frequency licenses and are actively carrying out application scenario tests.

Radio foundation industry innovation to ensure the safety of development. Radio is an important cornerstone of industrial innovation and development: weather radar helps people chase clouds and watch the wind to serve modern agricultural production; shortwave and satellite communications help people sail to the blue sea to carry out intelligent ocean transportation; satellite remote sensing helps people overlook the earth and explore oil, coal and other precious minerals; satellite measurement and control helps people to explore the moon and forge the glory of spaceflight; radio astronomy helps people look at the stars, explore the universe and pursue alien civilization.

Radio technology is also the "guardian" of social security, national security and the safety of people's lives and property: Beidou Navigation system is a Chinese program that provides integrated navigation and timing services for the world; special railway radio communication and control systems ensure safe and high-speed train movement; dedicated water communications and global distress and safety communication systems ensure that ships travel day and night; dedicated ground-to-air communications and navigation systems ensure that aircraft soar in the blue sky. In the face of major disasters, wireless communication is the only means of communication in emergency response, and airwaves are the lifeline of rescue and disaster relief; electromagnetic space security is an important part of national security, in modern warfare, electromagnetic warfare is the key factor affecting the outcome of the war.

Based on the new development stage, implement the new development concept, and build a new development pattern, on this 12th World Radio Day, we jointly advocate the efficient use of spectrum resources, the use of radio frequencies in accordance with the law, and the establishment of radio stations (stations). Maintain a good air wave order and serve high-quality economic and social development.
