The number of 5g network base stations in China reached 1.854 million, and the number of end users exceeded 450 million, accounting for more than 60% of the world. The 5g investment of national operators exceeded 400 billion yuan. This is what the reporter learned from the 2022 World 5g conference held in Harbin on the 10th. With the characteristics of large bandwidth, low delay and wide connection, 5g network is playing an enabling role in many industries such as industry, energy, medical care, education and transportation, and forming many typical application scenarios with commercial value. In particular, since the outbreak of COVID-19, the "non-contact" consumer demand has been constantly generated, providing a favorable market environment for the development of the 5g industry. Liu Liehong, chairman of China United Network Communications Group Co., Ltd., said that with the accelerated implementation of 5g applications, new industries, new formats and new models are emerging, and a number of Chinese enterprises are at the world's advanced level in 5g R & D and application. "China's 5g construction has made breakthrough achievements and has entered all aspects of social life. Significant progress has been made in the application of industrial Internet, smart cities, smart villages and other fields. We are constantly exploring new scenarios of uplink ultra wideband, real-time broadband acceleration and perceptual positioning." Said Wu Hequan, academician of the Chinese Academy of engineering and chairman of the future mobile communication forum. 5g is accelerating the development of digital economy. According to statistics, the accumulated investment in 5g by national operators is 401.6 billion yuan. Together with the consumption of mobile traffic and mobile information services, the accumulated direct and indirect economic output is 8.56 trillion yuan, and the economic added value is 2.79 trillion yuan. The conference was jointly sponsored by the people's Government of Heilongjiang Province, the national development and Reform Commission, the Ministry of science and technology, and the Ministry of industry and information technology.
