At the 2024 Shanghai World Mobile Communications Conference (MWC Shanghai Exhibition), which opened on June 26, companies competed to showcase new technologies and products, including direct satellite connectivity for automobiles, AI naked eye 3D smartphones, multi dialect speech recognition models, and 5G-A network integration applications. Through this grand event as a global benchmark in the field of mobile communication, the trend of technological advancement and industrial expansion in the information and communication industry can be seen. The reporter learned from the conference that relevant departments and industry enterprises will continue to promote innovation leadership, accelerate the innovation of new generation information technologies such as 5G-A, artificial intelligence, and quantum communication, orderly carry out the commercial scale of 5G-A technology, deeply tap the potential of information and communication technology integration application, and stimulate industrial development momentum. Standing in the exhibition hall, there is a surge of people and a lively atmosphere. A car equipped with Tiantong satellite communication function, the world's first, has attracted many viewers to "check in" experience. This is the first time in the industry that a car is directly connected to a satellite after a mobile phone. "The automotive direct satellite relies on China's independently developed 'Tiantong-1' satellite mobile communication system, providing a more complete communication method for in vehicle communication." China Telecom staff introduced that in places where ground communication networks cannot cover deep mountains, deserts, and other areas, car direct satellite communication can provide reliable two-way voice calls and two-way SMS communication services, ensuring that travel is always online and never lost. This also represents the trend of network infrastructure evolving towards air space integration. AI、 Cutting-edge technologies such as cloud computing have also shown the latest progress. In the exhibition hall, new products such as AI naked eye 3D tablets, AI naked eye 3D phones, and the first dual screen OLED notebook have attracted the attention of both domestic and foreign attendees. In addition, from traditional Chinese medicine consultations, AI painting, document translation, to dynamic graph neural network model architectures with 1 billion level parameters, intelligent computing models represented by China Mobile's "Nine Days" are being applied in multiple fields such as smart transportation, cultural tourism, finance, and retail to assist urban planning, travel management, and public services. Zhao Zhiguo, Chief Engineer of the Ministry of Industry and Information Technology, said at the meeting that the new generation of information and communication technology is an important engine for developing new quality productivity. "The new generation of information technologies, represented by cloud computing, artificial intelligence, digital twins, quantum communication, etc., are accelerating group breakthroughs. The integration of communication and AI, the integration of space and ground, and the integration of digital and physical entities have become future trends. Accelerating cross domain cross promotion and integrated development has become an inevitable choice." 5G has always been a hot topic in MWC. This year marks the fifth anniversary of the commercialization of 5G in China. During the conference, 5G-A (5G Evolution, also known as 5G Advanced) received much attention. 5G-A is accelerating the release of integrated innovation potential in multiple fields such as low altitude transportation, autonomous driving, smart water areas, industrial production, and smart cities. "Taking low altitude economy as an example, the large bandwidth and low latency characteristics of 5G-A can meet the communication and perception needs of low altitude drones, providing comprehensive guarantees for stable communication, safety supervision, and other aspects of low altitude economy." Liu Shuang, Deputy General Manager of RAN Product Marketing at ZTE, said that behind the new products and technologies, a network infrastructure with larger bandwidth, lower latency, and higher security is needed as support. The industry generally believes that 2024 is the first year of commercial use for 5G-A, and subsequent operators, industry chains, equipment, and standards will become more mature. Operators and equipment manufacturers have announced their 5G-A commercial plans and latest developments. Among them, China Mobile has proposed to achieve commercial deployment of 5G-A in 300 cities by the end of this year, strengthen cutting-edge technology research in the fields of 5G-A and AI, and accelerate the construction of a new network with business agility, personalized experience, and operation and maintenance automation; China Unicom will carry out 5G Advanced and integrated technology innovation, promoting intelligent upgrades from network elements and components to topology and systems, and creating a more agile, efficient, and intelligent ubiquitous intelligent network. "China is laying the foundation for the evolution of 5G-A." GSMA (Global Association for Mobile Communications Systems) Greater China President Si Han stated that China is the world's largest 5G market, and it is expected that the number of 5G connections in China will exceed 1 billion by the end of this year; It is expected that by 2030, the 5G market will contribute nearly 260 billion US dollars to the Chinese economy. Regarding the next step of development, Zhao Zhiguo stated that it is necessary to adhere to the principle of moderate advancement, coordinate the construction of 5G and gigabit optical networks, orderly carry out the commercial scale of 5G-A technology, combine application scenarios to promote 5G-A network coverage in key cities and hot areas, and accelerate the construction of intelligent computing infrastructure. Encourage the industry to actively participate in the development of 5G-A follow-up standards such as R19 and R20, promote the integration and innovation of communication, artificial intelligence, and integrated sensing technologies, and make forward-looking layouts for potential key technologies.
