The data released by the Ministry of Industry and Information Technology recently shows that the scale of 5G users continues to expand. As of the end of November, the number of 5G mobile phone users reached 1.193 billion, a net increase of 179 million from the end of the previous year, accounting for 65.3% of mobile phone users. In recent years, although the number of 5G users has maintained a growth trend, doubts about 5G have never stopped, and some even believe that 5G has cooled down and is useless. There are two main reasons behind these doubts. One is the price factor. From a hardware perspective, 5G terminals have higher costs than 4G terminals in terms of core components, patents, design, manufacturing, and other aspects. Although mid to low end 5G phones have gradually become popular, many existing 4G users are unwilling to spend money to actively replace their devices. From the perspective of tariffs, although the price of 5G packages has been lowered multiple times, the cost-effectiveness advantage is not significant compared to 4G packages. Some users still have the perception that "5G package data consumption is faster" and have no intention of upgrading. In addition, in recent years, the investment cost of 5G construction by operators has been relatively high, making it difficult to attract users through significant price reductions. The second is perceptual factors. The daily communication needs of most users are concentrated in social, video, shopping and other scenarios, which can already achieve smooth experience under 4G networks. The advantages of 5G's "large bandwidth and low latency" are difficult for ordinary consumers to intuitively perceive, and the "wide connectivity" feature of 5G is mainly aimed at industrial, IoT and other industry scenarios. The 4G era has given birth to lifestyle changing applications such as mobile payments, short videos, and ride hailing services, but to this day, similar phenomenon level applications have not yet emerged with the development of 5G. Therefore, for many existing 4G users, the consumer psychology of "enough is enough" dominates and lacks the motivation to switch to 5G packages. But does this mean that 5G is useless? The answer is clearly negative. To determine the value of a communication technology, we cannot only look at the consumer end, but also consider the overall development of the industry. There is a "80/20 rule" for 5G applications, which means that 20% of the application scenarios are in the personal consumption field and 80% of the application scenarios are in the industry. It can be seen that the core value of 5G has never been limited to "making mobile internet access faster", but as a key infrastructure for new quality productivity, it builds a "high-speed bridge" for the transformation and upgrading of the manufacturing industry, and the deep integration of the digital economy and the real economy. In the industrial field, 5G has reshaped the production model of Chinese manufacturing. In intelligent workshops, the low latency characteristics of 5G support the precise collaborative operation of robotic arms. The wide connectivity capability of 5G allows a single production line to simultaneously meet the customized production needs of multiple products, greatly improving production efficiency and resource utilization; In the operation and maintenance process, technicians can diagnose and repair equipment thousands of miles away through 5G+AR glasses without the need to rush to the site. Data shows that the average production capacity of the 100 globally leading 5G factories cultivated in China has increased by 25%, product quality has improved by 21%, and operating costs have decreased by 19%. In the fields of people's livelihood and society, 5G has created more possibilities. In the medical industry, 5G+remote surgery breaks geographical limitations and allows experts from first tier cities to provide real-time guidance to hospitals in remote areas to carry out difficult surgeries; In the education industry, 5G+holographic classrooms break down barriers between urban and rural educational resources and achieve greater educational equity; In the transportation industry, 5G supported vehicle road collaboration systems provide millisecond level road condition information for autonomous driving; In the field of agriculture, 5G+Internet of Things has achieved precise monitoring of crop growth in farmland. 5G continues to weave a dense livelihood security network, benefiting thousands of households with the dividends of digital transformation. More importantly, 5G is not just an independent technology, but also a "paving stone" for other cutting-edge technologies. From artificial intelligence edge computing to AR/VR immersive experience, 5G is required to provide high-speed, large bandwidth, and low latency network support. The accumulation of 5G technology has also laid the foundation for the development of 6G. Without the exploration of network architecture and spectrum resources by 5G, the construction of 6G's "air space integration" network is also impossible to talk about. Looking back at the evolution history of communication technology, similar "uselessness theories" have not appeared for the first time. In the early stages of commercial use of 4G, it was also questioned that it was "just a little faster than 3G", until the outbreak of mobile payments, short videos and other applications truly changed social life. The development logic of 5G is different from that of 4G. The value of 4G bursts in the consumer end, while the value of 5G settles in the industrial end. The digital transformation of industries is a long-term process and cannot be achieved overnight. The so-called 'encountering coldness' is precisely the rational return of 5G from the construction boom to deep application cultivation. On the one hand, the upstream and downstream of the industrial chain continue to optimize 5G network coverage, reduce package fees, enrich application scenarios, and promote consumer experience upgrades; On the other hand, the integration of "5G+" applications has moved from "model rooms" to various industries. The value of 5G will eventually be seen by more people as the consumer and industry sides work together to achieve synergy. (New Society)
