As information and communication technologies and applications are deeply integrated into economic and social development, the important role of the information and communication industry in empowering and empowering thousands of industries has been continuously demonstrated. New industrialization and modernization of all walks of life are inseparable from the basic support and Stacking multipliers.
"The strategic, basic, and leading industry characteristics of the information and communication industry determine that it can play a particularly important role in the overall situation of Chinese-style modernization." At the 2023 World Telecommunication and Information Society Day Conference, Zhang Yunming, Vice Minister of the Ministry of Industry and Information Technology said so .
In particular, China's 5G has achieved world-renowned achievements in network construction and large-scale application in the past four years. my country has built the world's most technologically advanced and largest 5G SA network, and 5G has been integrated into 52 of the 97 national economic categories, and its application continues to expand and deepen.
Today, a new round of 5G innovation is starting, and my country's 5G commercial deployment and large-scale application development are ushering in a new important juncture. In terms of technological evolution, with the freezing of the Rel-18 standard this year, the era of 5G Advanced is beginning. This is a key development stage before the arrival of 6G. 5G and AI will be more closely integrated. 5G satellites, new passive objects New technologies such as networking and communication perception integration are maturing. While the technical capabilities are enhanced, the empowering role of 5G will become more apparent, promoting the realization of a wider Internet of Things, wider coverage, more accurate perception, and smarter connections.
5G 100 Billion New Track Opens
In the past four years of commercial use, my country's 5G large-scale deployment and large-scale application have made great achievements.
In terms of network construction, my country has opened a total of more than 2.64 million 5G base stations, covering all prefecture-level urban areas and all county-level urban areas across the country, as well as key scenarios such as ports, hospitals, and mines.
In terms of large-scale applications, my country has built a total of 16,000 5G industry virtual private networks. The application of 5G in mining, electric power, smart ports and other fields has begun to be replicated and promoted. Pilot explorations in fields such as medical care and education have continued to deepen. Typical application benchmarks and solutions The program matures faster.
At present, the 5G private network revenue of the three operators has exceeded 10 billion yuan, and 5G has driven DICT revenue to exceed 100 billion yuan. In other words, every 1 yuan of 5G private network revenue can drive 10 yuan of DICT revenue. The "prosperity" in six aspects, including scenarios, commerce, ecology, industry, policy, and standards, supports the new 5G 100 billion track.
A new second round of 5G innovation opens
5G is constantly evolving, making itself stronger and making the Internet of Everything a reality.
Rel-15 is the first version of the 5G standard and is also the basic standard of 5G. It mainly meets the needs of the outside world for eMBB (enhanced mobile broadband) application scenarios. Simply put, it is to allow users to move online faster. The subsequent Rel-16 standard is the full version of the 5G standard, which mainly improves the 5G's URLLC (ultra-reliable and low-latency) capabilities, making 5G's ability to support vertical industries significantly improved.
The technical capabilities of 5G continue to improve, and its empowering effect on thousands of industries continues to emerge. Xu Hao, head of R&D of Qualcomm China, said that the Rel-18 5G standard is expected to be completed by the end of this year, which marks the beginning of the second round of 5G innovation. "It is expected that from 2027 to 2030, the industry will start the formulation of 6G standards." At the "5G Construction and Application Innovation" forum, the lightweight 5G technology RedCap was called "the most popular fried chicken" and became the focus of the industry, and was regarded as a new hot spot to promote 5G innovation.
The new passive IoT technology is also attracting attention, which will be one of the "star technologies" in the 5G Rel-18 standard. In view of the shortcomings of existing RFID equipment such as transmission distance range, poor network anti-interference ability, and poor positioning accuracy, 3GPP proposed a new terminal type "new passive terminal".
At present, the industry is optimistic about the prospects of RedCap technology because it achieves a "balance between low cost and performance":
1. RedCap can realize the low latency and network slicing capabilities of 5G;
2. RedCap has advantages in low power consumption and low cost.
China Mobile is simultaneously promoting the research and development of passive IoT technology in two ways, the networking architecture and the cellular architecture, and hopes to commercialize it in stages in the future. At present, product research and development has been completed in terms of networking architecture, which has the advantages of continuous network coverage and low-cost meter-level positioning. The pilots in many places have achieved good results and are accelerating commercial use. In terms of cellular architecture, it is currently in the prototype testing stage.
5G+AI camera
There are many challenges in the wireless field, but many challenges have not been solved by certain theoretical research or mathematical models.
AI makes 5G better, and 5G will make AI more ubiquitous. With the accelerated expansion of 5G, AI processing is continuously expanding to the edge side. The future of artificial intelligence will be a hybrid AI architecture. AI will run collaboratively on the cloud, edge cloud, and terminal side, so that the computing and processing capabilities in the entire system can be redistributed in the most effective way, and start a large-scale transformation of the edge of intelligent network connection. .
In the future of 5G, synesthesia integration or synaesthesia fusion (communication and perception) will be one of the necessary features. Through the integrated air interface signal and diversified perception design, while communicating, it has new perception capabilities such as distance, speed, and angle, so as to build a low-cost, high-performance, seamless and ubiquitous synaesthesia integrated network, supporting the Internet of Vehicles, wireless Rich business in man-machine and other aspects.
In China, the IMT-2020 (5G) promotion group has also promoted research and experiment work in stages on the five major topics of 5G-A synaesthesia fusion scenarios, network architecture, evaluation methods, air interface technology, and technology testing. According to reports, in the relevant 5G millimeter wave synaesthesia fusion test, the sensing distance of the detection vehicle in the traffic scene exceeded 500 meters, achieving lane-level sensing accuracy; in the low-altitude scene, stable drone tracking was achieved, with a tracking distance of more than 1200 meters . In the 5G low-frequency synaesthesia fusion test, the detection distance of drones in low-altitude scenes exceeds 1,400 meters, and the indoor breathing detection accuracy can reach 95%.
5G technology is evolving and moving towards a wider network, wider Internet of Things, more universal coverage, more accurate perception, and smarter connections. It will expand richer application scenarios and make the world a better place.
"Making 5G with 5G"
"'Making 5G with 5G' is ZTE's concept and model for intelligent manufacturing." Zhou Jianfeng, vice president of ZTE, said, "The Binjiang base is a 'model room' for practicing this concept."
This manufacturing base, which has invested about 20 billion yuan in construction, is the most advanced base for ZTE to produce 5G-related products using the smart factory model. As a 5G network technology research and development and 5G equipment manufacturing enterprise, ZTE has taken advantage of both 5G and manufacturing. Over the past three years, it has carried out 5G full-connection transformation on the Nanjing Binjiang Base, and widely used technologies such as robots, machine vision, and 5G+ digital twins to realize The entire process of R&D, production, and operation is intelligently integrated, resulting in a significant increase in production efficiency.
At present, the Nanjing Binjiang base can produce 70,000 base station (small station) equipment and 40,000 servers per month. Compared with 2020, the output per person-hour of base station products will increase by 113%, and the output per person-hour of server products will increase by 125%; At the same time, the logistics turnover efficiency is increased by 50%, and the delivery cycle is shortened by 48%. Zhou Jianfeng focused on the 5G flexible and automated production line. "In the assembly process, the video captured by the high-definition camera on the robotic arm is transmitted to the background through 5G CPE technology, and the centralized calculation and analysis are then fed back to the robotic arm to make actions." He said, "Therefore, each accessory can be Not the same, according to the different accessories taken, the accessories and screws are automatically installed."
"5G can establish a 99.999% stable communication network, which is almost the same as a wired network. Through a 5G fully connected factory, it can truly realize end-to-end flexibility and automated production and transportation of products without landing, and greatly improve production efficiency." Zhou Jianfeng said.
The "heart", "legs" and "hands" of a smart factory
Walking on the road of the production line, you can't see the workers, but you encounter self-driving cars from time to time. "You can rest assured to follow me, 'Xiaoxing' will take the initiative to avoid you, and will not hit you." Zhou Jianfeng said with a smile. The "Xiaoxing" in his mouth is an AGV (Automatic Guided Transport Vehicle) that shuttles through the factory.
"In this smart factory, the AGV car is like legs, the robotic arm is like hands, the intelligent operation center is the brain, the raw material warehouse is the heart, and the transportation track between workshops is the blood vessel." He said vividly, "5G has realized All parts are fully connected. The factory has realized "unmanned" operation and independent production under "black light" to a large extent.
Indeed, many areas of the workshop are dark, some areas are dimly lit, and few points are normally illuminated. The reporter found the answer in front of a picture-the workshop implements a three-stage mode of "black light-morning light-day light": "black light mode" refers to an unmanned working environment, only intelligently controlled machines are busy; "morning light mode " refers to an automated autonomous working environment with human assistance; "daylight mode" refers to a human working environment. The first two modes accounted for more than 90%.
Each part of the smart factory performs its own duties, basically no rest is required, and the error rate is close to zero. Zhou Jianfeng said that if a device is "sick" occasionally, the intelligent operation center is comparable to an "old Chinese doctor". Through "seeing, hearing, asking, and knowing", the online "pulse" can identify the "illness" and "prescribe the right medicine".
In Zhou Jianfeng's view, the key to smart factories is to break through the pain points, blocking points and difficulties of traditional manufacturing through digitization and intelligence, and achieve real results, instead of simply pursuing coolness and "tallness". "A little bit of small improvements add up to a big leap." Zhou Jianfeng said, "5G fully connected smart factory" was not built in a day. come.
