After five years of development, China's 5G is not only far ahead in the world, but also changing our production and lifestyle in many fields. At the same time, businesses such as live broadcast e-commerce, naked-eye 3D, remote control, and flexible production are on the rise, placing higher demands on network bandwidth and latency. As a 5G evolution technology, 5G-A is developing at the right time. 2024 is regarded by the industry as the first year of 5G-A commercialization.   As we all know, the first version of 5G-A3GPP (R18) will be frozen in the first half of this year, and the industry’s first batch of 5G-A full-scenario and full-series solutions have been released. Not only that, the three major operators have also used the high bandwidth, low latency, positioning accuracy and other characteristics of 5G-A technology to do a lot of technology and scenario exploration and innovation.   As the main force in technological innovation and network construction, China Telecom has joined hands with Huawei and other industry chain partners to create benchmark projects in the fields of 3CC (Three Carrier Aggregation) and RedCap in Shanghai, Hubei, Shaanxi, Guangdong, Fujian, Jiangsu and other places in the past year. .   So, what value will these innovations and achievements bring to the industry? In order to quickly promote 5G-A towards commercial use, what preparations need to be made in the industry chain? What other trends should we pay attention to in the future? Let’s take a look at the interpretation one by one. At the beginning of 2024, 5G-A frequently spreads good news. It turns out that China Telecom has completed 3CC contiguous deployment in multiple provinces and cities.   3CC is a new term, I believe many people find it novel. In fact, 3CC (Component Carriers) refers to three-carrier aggregation, which is also one of the key features of 5G-A. 3CC can combine the operator's three frequency bands of 5G signals to transmit more data, just like merging three different lanes into a wider highway.   3CC is really an artifact to deal with the network bandwidth bottleneck caused by new services such as live broadcast and cloud games! It is understood that Shanghai Telecom, Guangdong Telecom, Shaanxi Telecom, Hubei Telecom and Fujian Telecom have become the first batch of people to eat crabs.   Shanghai is at the forefront of 5G development in the country, and it is even more pioneering in the 5G-A era. On January 25, Shanghai Telecom and Huawei completed the first F+T 3CC 100-site deployment in China. By using 3.5GHz+2.1GHz three-carrier aggregation technology, the measured downlink rate was nearly 4Gbps and the uplink rate was nearly 1Gbps. For Hengshan Road in Xuhui District The user experience in densely populated areas has been significantly improved.   The booming development of the live broadcast economy has put forward higher requirements for both the uplink and downlink experience of 5G net...

Microsoft recently released a lightweight AI model called Phi-3 Mini, which is designed to run on smartphones and other local devices. The 3.8 billion parameter model is the first of three Phi-3 language models to be released by Microsoft. The goal is to provide a more affordable alternative to cloud-driven large language models, making AI technology accessible to smaller organizations. Microsoft says that the Phi-3 Mini easily outperforms previous Phi-2 mini-models and is on par with larger models like the Llama 2. Surprisingly, the responsiveness of this new model is close to that of those with 10 times the size of the parameters.   In their paper, the research team notes that the key to this innovation lies in the training dataset they use. The dataset is based on the Phi-2 model, but incorporates "tightly filtered network data and synthetic data." This unique way of constructing datasets is inspired by children's books that use simpler language to illustrate complex topics, effectively enabling smaller language models to be more effective. While Phi-3 Mini may not be able to compete with cloud-powered large language models in some ways, it has demonstrated strength over Phi-2 and other small language models (e.g., Mistral, Gemma, Llama-3-In) in tasks ranging from math to programming to academic testing. What's more, this model can run on a device as simple as a smartphone, and it doesn't require an internet connection.   However, the main limitation of the Phi-3 Mini is its breadth of "factual knowledge", which is mainly due to its relatively small training dataset. As a result, it did not perform very well in the "TriviaQA" test. Still, it's a big step forward for models that only need to work with smaller internal datasets. Microsoft hopes that by rolling out such a model, AI technology will be accessible to companies that can't afford to connect to a large language model in the cloud.   Currently, Phi-3 Mini is already available on platforms such as Azure, Hugging Face, and Ollama. Microsoft also plans to release more powerful Phi-3 Small and Phi-3 Medium models, with 7 billion and 14 billion parameters, respectively.

U.S. Steel shareholders approved the sale of the company to Nippon Steel. About 71% of U.S. Steel shareholders voted in favor at the special meeting, but opposition from unions and ongoing regulatory scrutiny have cast doubt on the $14.1 billion deal.  U.S. Steel shareholders approved the deal amid widespread expectations. Under the terms of the deal, Nippon Steel will pay $55 per share, a price that was seen as a huge premium when the takeover was announced in December. However, some U.S. lawmakers have since publicly expressed opposition to the deal, citing national security concerns. U.S. President Joe Biden also said that U.S. Steel must remain an American company. Affected by the transaction, U.S. Steel's stock price closed down 2.1% on Friday.  At the same time, the deal has also triggered strong criticism from the United Steelworkers (USW), who are worried that it may cause workers to lose their jobs. In response to the vote, USW said: "We are not surprised that shareholders have chosen to cash out and sell employees and retirees of this iconic American company."  In addition, regulatory agencies are also reviewing the transaction. According to Reuters, the Committee on Foreign Investment in the United States (CFIUS), the agency responsible for reviewing foreign investments in U.S. companies, has met with all parties to discuss the matter.  On the other hand, according to Politico, the U.S. Department of Justice has launched an in-depth antitrust investigation into the acquisition.  Nippon Steel has promised not to lay off workers due to the agreement, will abide by all agreements with the U.S. Steel union, and plans to move its U.S. headquarters to Pittsburgh, where U.S. Steel is located. In this bid, Nippon Steel defeated rivals Cleveland Cliffs, ArcelorMittal and Nucor and successfully won the right to acquire U.S. Steel.  However, U.S. Steel shares have not yet reached the $55 offer price, suggesting investors expect the controversy surrounding the deal to delay the closing. The companies had previously said the deal was expected to close in the second or third quarter of this year. But Bloomberg News, citing people familiar with the matter, reported that the two steelmakers are expected to announce that the deal is expected to be completed in the second half of 2024.

According to Digitimes, citing supply chain sources, Apple is actively discussing with multiple suppliers to apply glass substrate technology to chip development. Industry insiders generally believe that the application of glass substrates will bring revolutionary breakthroughs to chip technology and is expected to become one of the key directions for future chip development.    Traditional chips’ printed circuit boards ( PCBs) are typically made from a mix of fiberglass and resin. This material does not dissipate heat well, and the heat generated during operation of the chip can cause its performance to degrade ( thermal throttling). This means that the chip can only maintain maximum performance for a short period of time, and has to run at a reduced frequency once the temperature gets too high.    The glass substrate is resistant to high temperatures, allowing the chip to maintain peak performance for a longer period of time. At the same time, the ultra-flat properties of the glass substrate allow for more precise etching, allowing components to be arranged more closely together and increasing circuit density per unit area.    Currently, Intel leads the way in this technology, but other companies are trying to catch up. According to reports, Samsung has begun developing glass substrate technology, and Apple is also in close discussions with it and other undisclosed suppliers.    Industry experts point out that glass substrates are not only an innovation in materials, but also a global technology competition. In addition to substrate manufacturers, global IT equipment manufacturers and chip manufacturers will also actively participate. Samsung has a unique advantage in this area because the production process of glass substrates is similar to that of advanced multi-layer displays.    In the past, chip performance improvements mainly relied on continuous shrinkage of manufacturing processes, and this shrinkage is about to reach physical limits. The industry is skeptical about the future development of Moore's Law, so new materials such as glass substrates are regarded as the key to breaking through bottlenecks and maintaining chip performance growth.    However, glass substrates also have many technical problems, such as fragility, insufficient adhesion to metal wires, and difficulty in controlling the uniformity of through-hole filling. In addition, the high transparency of glass and the different reflectivity from silicon will also cause difficulties in the detection and measurement process. Many existing measurement techniques are designed for opaque or translucent materials, and measurement accuracy may be compromised when using these techniques on glass substrates.    Despite the challenges, glass substrates are still regarded by the industry as one of the future development directions of chip packaging. Apple's active participation may accelerate the maturity of gla...

(CWW) Since it was first proposed in September 2023, new productivity has become a hot word in the Chinese economy. At the National Two Sessions in 2024, new productivity was included in the government work report for the first time, and accelerating the development of new productivity was listed at the top of the top ten tasks in 2024. At a time when new productivity has become a hot word, how to speed up the development of new productivity has become a topic discussed by all walks of life.   On March 20, at the "2024 Mobile Resale Industry Ecological Development Conference" hosted by Xintong Media·Communication World All Media, hosted by the Internet of Industry, and co-organized by the Virtual Operation Branch of the China Communications Enterprises Association, Deputy Chief Engineer of the China Academy of Information and Communications Technology He Wei said that after reviewing the content of new productivity in existing reports and meetings, it can be found that to accelerate the development of new productivity, it is especially important to give full play to the leading role of innovation and promote industrial innovation with technological innovation. Promoting industrial innovation through scientific and technological innovation is the core element of developing new productive forces. At the same time, industrial innovation will help accelerate the application and implementation of scientific and technological innovation achievements.   Talking about why technological innovation should be used to promote industrial innovation, He Wei explained that "innovation" is the entire chain from front-end basic research, applied basic research, to technology development, productization, and then to scale and industrialization. Technological innovation mainly focuses on the improvement of scientific and technological levels. Industrial innovation is the process of using scientific and technological innovation results to form new industries or transform existing industries. Its goal is to apply appropriate factor inputs, technical levels and organizational methods to obtain higher value output benefits. Therefore, accelerating the promotion of industrial innovation is particularly important for the development of new productive forces.     "Under the new situation, the need for industrial innovation is becoming more urgent." He Wei said, on the one hand, digitalization is integrating and penetrating into the industrial economy in an unprecedented way, and giving birth to digital economic forms, artificial intelligence, quantum information, humanoid robots, brain-computer Digital technologies such as interfaces will become the biggest variables of the times and technology. On the other hand, the global division of labor has driven the continuous adjustment of the competition pattern, factor structure and development direction of the value chain. Countries have seized the key hub position in the global innovation network. T...

From March 15th to 17th, the China Electric Vehicles 100 Forum (2024) with the theme of "Consolidating and Expanding the Development Advantages of New Energy Vehicles" was held at the Diaoyutai State Guesthouse in Beijing. At the Chelu City sub-forum on the 15th, Huang Gang, deputy general manager of China Mobile Research Institute, made a speech about the "four integrations" of the Internet of Vehicles industry, which attracted industry attention.  At the beginning of 2024, China Mobile Chairman Yang Jie proposed the idea of actively grasping the trend of the "AI+" era and promoting the extension of "5G+" to "AI+". Based on this, the Shanghai Research Institute has delved into 5G-A technology to build a new infrastructure of "ubiquitous integration" to provide integrated services of information perception, transmission, storage and processing for AI+ applications.  Technology Empowerment and Ubiquitous Integration Based on industry needs in the field of Internet of Vehicles, China Mobile continues to carry out innovative exploration and implementation practices with Chinese characteristics.
