On May 17, the Ministry of industry and information technology announced at the 2022 World Telecommunication and information society day conference: at present, China has built nearly 1.6 million 5g base stations, becoming the first country in the world to build 5g networks on a scale based on independent networking mode; 5g applications cover many life fields such as transportation, medical treatment, education, culture and tourism, with a total of more than 20000 cases. There is an undeniable fact behind the gratifying results - 5g, which is "grounded" in the field of to B, has not gained the same "popularity" in the market of to C. Compared with the rise of industrial tracks, 5g with high bandwidth, low delay and wide connection is facing the dilemma of "being too high and too few" in personal tracks. According to the financial reports of the three major operators in the first quarter of 2022, the number of 5g package users in China has reached 849 million. The increasing number of users has not brought about the vigorous development of 5g personal application field. What's the problem? Technology defines tools, and tools determine value. To enhance the vitality of 5g to C, personal terminals need to achieve a qualitative leap. It is not difficult to find that the coverage of 4G network and the popularity of large screen smart phones have opened the door to the era of mobile Internet. With the rapid development of network and hardware, 4G mobile phones have three attributes: communication tools, entertainment tools and productivity tools. Today, 5g network has become mature, but the development of hardware technology lags behind obviously. On the one hand, 5g mobile phones have not made a major breakthrough in function compared with 4G mobile phones, and 4G mobile phones can still meet a variety of use needs. On the other hand, personal devices closely related to 5g applications have not been widely popularized. Restricted by the technical level, VR experience anytime and anywhere, holographic call within reach, efficient and convenient cloud computer office, and the high-tech application scene depicted by 5g is still a long distance from real life. As a tool, 5g mobile phone itself failed to produce qualitative change, which undoubtedly had a deceleration effect on the development of consumer market and application market. The following set of data can best illustrate the problem: according to the data released by the China Academy of communications and communications, the domestic 5g mobile phone shipment decreased by 22.9% year-on-year in the first quarter of 2022, and the 5g mobile phone shipment decreased by an alarming 41.1% year-on-year in March. Application shapes habits, and habits make the market. Those who get popular apps get 5g personal market. An application can become popular, and its value must lie in changing people's inherent habits. The popular application in the 4G era has changed people's communication mode from SMS to wechat, and the way of obtaining information from text to video, which has achieved the blowout development of the Internet industry. However, at present, the mainstream use needs in daily life and work can still be met by relying on 4G applications. Opening the application market, the long-awaited 5g popular application has not appeared yet. What are the popular applications in 5g era? 5g message? 5g new call? The industry and consumers have not given an answer. But it is certain that the 5g personal market cannot enter the fast lane of development due to the lack of catalyst for popular applications. The key to enabling 5g development to make a leap in the to C field and reversing the downturn is to strengthen efforts to explore the non alternative use value and exclusive use scenarios of 5g personal applications, and promote the research and development of hardware technology to achieve a revolutionary breakthrough. The whole industry should further deepen the cooperation with hardware manufacturers and software service providers. The areas of cooperation should be fully extended in the whole industry chain. In addition to the development of basic communication products and application products, the R & D and innovation of basic materials, interactive technology and profit model will become the key to make 5g "grounded" and "popular".
