China's official recently announced 6G (sixth -generation mobile communication technology), and it is expected that commercial applications will be realized around 2030.5G is the mainstream of Chinese society. According to the data released by the Ministry of Industry and Information Technology on November 22, as of the end of October, the 5G mobile phone users of three basic telecommunications companies in China reached 754 million.However, the "out of the new" potential is so rapid, accompanied by the question of "innocent" -how to retreat from 2G and 3G?There are technical difficulties and sociological difficulties.

Technically, 2G and 3G returning nets are an inevitable choice for the update of China Mobile Communications Network to today.Radio spectrum resources and mobile base stations are limited.Only by replacing 4G and 5G with a significant improvement efficiency of 2G and 3G networks, and 6G networks in the future, can we adapt to the rhythm of the "Digital Age" and meet the requirements of many production and life application scenarios in terms of network rates, capacity, and security.Essence

But as the relevant person in charge of the Ministry of Industry and Information Technology of China recently said, "Action Communication Returning the Net is not simply 'retreating and retreating', and user guarantee measures need to be improved."In September of this year, a consumer in Guangzhou complained that its mobile phone became a "one brick" because the telecommunications company closed the 2G base station, which caused heated discussions on the Chinese Internet because there were actually many people with "resonance".

At present, 2G and 3G mobile network users are dominated by elderly groups, and this group can be said to be huge based on China's population base.According to the in-depth analysis and investment value research consultation report released by the elderly mobile phone industry from 2023-2028 issued by the China Research Institute, the current market size of nearly 60 million units in the mobile phone consumer market in China, including supporting 4G or 5G functionsThe proportion of smartphones is only 10%.

China's official statement is that in the next step, telecommunications companies will formulate a retirement plan by combining their own situation.The Ministry of Industry and Information Technology will promote it in accordance with laws and regulations and do a good job in the protection of user rights and interests.At the specific level of operation, it is not difficult to see that it is indeed a process of adapting to human conditions.Taking China Mobile, one of the three major communication operators in China, it clearly stated in 2020 to stop adding new 2G IoT users by the end of the year.However, China Mobile is still available for 2G base stations at present, and there are also telephone cards to support 2G signals, which can be used with 4G+2G full Netcom elderly.

China's mainstream public opinion has discussed 2G and 3G networks as early as 2016.In 2021, the Ministry of Industry and Information Technology issued the "Fourteenth Five -Year Plan" information and communication industry development plan, which clearly proposed that "accelerate 2G and 3G network retreats and coordinate 4G and 5G network coordinated development."It can be seen that the topic of 2G and 3G retirements is recently "re -mentioned by old things."The implementation of this matter, China has both determination and patience from the official to the folk.

Looking at the world, 76 operators from 43 countries and regions last year have completed or planned to close 2G networks. 80 operators in 42 countries and regions have completed, planned to be carried out or in the process of closing 3G networksEssenceTaking the United States with a large population and economy as an example, as the country's mainstream telecommunications operator Verizon closed its 3G network on the last day of 2022, the United States' 2G and 3G networks basically "disappeared."

Therefore, in the long run, China has added the "trend of the general trend" of 2G and 3G returns, and there is no difficulty to overcome it.
