Digital technology has been integrated into various fields and the entire process of economic and social development, and millions of people enjoy the benefits of digital intelligence. The smooth information "artery" is bursting with strong momentum, helping the digital China giant ship sail through the wind and waves. The latest data shows that China has built 3.837 million 5G base stations, accounting for over 60% of the global total, achieving "gigabit connectivity in cities, 5G connectivity in counties, and broadband connectivity in villages"; The total scale of computing power ranks second in the world; The global proportion of necessary patent declarations for 5G standards has reached 42%, and the global market share of 5G base stations and mobile phones exceeds 50%; Industrial Internet has initially established five systems of network, logo, platform, data and security; The integration of 5G applications into various industries, achieving large-scale promotion in industries such as industry, power, mining, healthcare, and education... Behind the string of numbers, lies the arduous journey of the information and communication industry. "In 1994, China had full function access to the Internet. At that time, there was only one 64K network cable, and the speed was very low." Zhao Zhiguo, spokesperson and chief engineer of the Ministry of Industry and Information Technology, once said that after 30 years of development, China has 1.09 billion internet users, forming the world's largest digital consumer market. The information and communication industry is a strategic, fundamental, and leading industry that builds national information infrastructure, provides networks and information services, and comprehensively supports economic and social development. With the accelerated development of Internet, Internet of Things, cloud computing, big data and other technologies, the connotation of the information and communication industry is constantly enriched, extending from traditional telecommunications services, Internet services to new business formats such as Internet of Things services. Data shows that China's online retail sales will reach 15.42 trillion yuan in 2023, ranking first in the world for 11 consecutive years; Mobile payments have become a part of daily life, with a 239 fold increase in scale compared to 2012; The software industry's revenue has exceeded 12 trillion yuan, maintaining double-digit growth for 23 consecutive years. At the same time, with the rapid expansion of 5G networks, the 5G terminal market is growing rapidly, and 5G technology is entering millions of households. According to data released by the China Academy of Information and Communications Technology, the domestic market shipped 147 million mobile phones in the first half of this year, a year-on-year increase of 13.2%. Among them, there were 124 million 5G mobile phones, a year-on-year increase of 21.5%. Domestic brand mobile phones performed strongly, accounting for 84.4% of mobile phone shipments during the same period. The latest data for the first quarter of 2024 released by market research firm Counterpoint shows that in the Chinese market, the domestic operating system HarmonyOS has surpassed iOS for the first time, becoming the second largest smartphone operating system. With the further popularization and deepening application of 5G technology, as well as the innovative integration of artificial intelligence technology in the field of mobile phones, the domestic mobile phone market is expected to continue to grow. The empowerment effect of integrated application scale development continues to be released at the Zhuonai Lake Protection Station in Kekexili at an altitude of 4800 meters. The opening of 5G base stations has changed the previous mode of relying only on manual inspection. Now, staff can understand the situation of the protection area at any time through large screens. The first certified five-star 5G factory in China, ZTE Nanjing Intelligent Binjiang 5G Factory, has recently been completed, becoming a new benchmark for the deep integration and comprehensive application of 5G technology and electronic equipment manufacturing industry. The construction of China's 5G factory not only represents the direction of digital transformation of the manufacturing industry, but also provides a Chinese solution for the development of the global "5G+industrial Internet". In Chongqing, known as the "8D Magic City", the world's first underground tunnel 5G+Beidou satellite navigation system has been officially put into use, achieving second level positioning inside the tunnel and meeting the lane level navigation experience, filling the technical gap in domestic underground tunnel satellite navigation. Relying on the country's first 5G+drone blood transportation intelligent airport platform, a drone carrying emergency blood departed from Shenzhen Blood Center and delivered the blood to Luohu District People's Hospital in just 9 minutes. 5G low altitude network makes life channels safer and faster. The massive new infrastructure of 5G not only provides users with high-speed and low latency connection experience, but also provides fertile soil for the incubation of innovative applications. Built well, it's even more important to use it well. Nowadays, 5G applications in China have been integrated into 74 major categories of the national economy, with 30000 5G industry virtual private networks and 300 5G factories built. 5G is widely replicated in vertical industries such as mining, power, and ports, helping enterprises improve quality, reduce costs, and increase efficiency. The number of "5G+Industrial Internet" projects exceeded 14000. The new generation of information technology accelerated its application breakthrough, enabling the transformation and upgrading of the real economy in digital, networked and intelligent ways. The integration and symbiosis of digital technology have opened the era of "intelligent connection of all things". China adheres to the principle of moderate advancement and simultaneous construction and application, consolidates network facilities, and is orderly promoting the evolution and upgrading of 5G networks towards 5G lightweight and 5G-A, solidly promoting the development of the computing power industry. This is not only a remarkable achievement, but also paves a new path for the successful development of China's information and communication industry. The information and communication industry is one of the fastest-growing and most innovative fields. Nowadays, artificial intelligence, as a strategic technology leading a new round of technological revolution and industrial transformation, is driving the information and communication industry into the era of artificial intelligence. In this era, the combination of networks and AI, communication and perception, and the integration of heaven and earth are becoming new directions for development. Wu Hequan, academician of the CAE Member, pointed out that 5G innovation will continue to work in broadband, active adaptation, lightweight, intelligent and other aspects. Especially in terms of intelligence, large models are embedded in smartphones, ushering in the era of AI smartphones. On the one hand, large models can provide users with AI search, AI drawing, document summarization and other functions, significantly unleashing content creativity, enhancing user experience, and reducing the threshold for generating intelligent audio and video content. On the other hand, the large-scale model 'sinking' into mobile phones may activate the trillion yuan scale mobile phone industry, and 5G+AI can also promote the development of wearable devices towards spatial computing. International Data Corporation (IDC) predicts that intelligent terminals embedded with large models will be widely used in fields such as animation and video creativity, gaming and virtual worlds, speech synthesis and conversion, visual and image processing, chatbots, personalized recommendations, medical assistance, automated content generation, and facial recognition. The new era of "Internet of Things" will open up unlimited imagination space. (New Society)
