ã€World Wide Web Reporter Zhang Yang】 Today, the vast majority of people are using smart phones. When we skillfully open WeChat for voice and video chat and grab red envelopes, few people seriously think about what makes today. Mobile life?
As a science and technology reporter, I have always been curious as to what kind of group of people I am and continue to explore new communication technologies to bring about such a big change in our lives. Recently, during a visit to China by Lorenzo Casaccia, a Qualcomm vice president, the reporter interviewed him and conducted in-depth research on the scientists behind the 5G technology.
Ke Shiya has been working in Qualcomm for nearly 17 years. He is the vice president of global standards for Qualcomm's technical standards and is responsible for the coordination of Qualcomm and the 3GPP organization. 3GPP is an important global standards organization, and 2G, 3G, 4G and future 5G technology standards all come from this organization. And Ke Shiya has been focusing on the field of cellular communication technology. He experienced almost the entire wireless cellular technology development process at Qualcomm. .
5G will be a common platform
When it comes to 5G technology, it can be said that it is one of the most popular tech vocabularies of the moment, but people have different understandings of it: Some people say that it is a high rate, low delay, others say it is a new ecology, people are talking about 5G. The understanding of technology can be said to be deepening. So for such a communication expert, how does Ke Shiya understand 5G?
Mr. Ke Shiya's answer is quite philosophical - "Review history and look forward to the future." Ke Shiya told the Global Network Technology reporter that “The understanding and prospect of 5G technology must be viewed from the perspective of the history of communications technology. The first generation of communication technology is mainly a voice function, and the second generation has added data and the third generation of data. With richer functions, 4G has achieved a great leap and brought together scenes of broadband, voice, telematics, and prototypes of the Internet of Things. Just as the 4G LTE technology was named, the entire communications technology has undergone long-term evolution, and 5G technology will continue to continue. This trend of development, so we will see, greater bandwidth, higher data rates, lower latency, more advanced IoT M2M (Machine to Machine) communications, and more advanced multimedia applications. The impact of 5G on people will be incalculable, just as it was difficult for us to predict that applications such as WeChat, Didi, and Uber will be so hot in the 4G era. The future may be virtual reality, perhaps a robotic application, and it is still very Hard to say, but one thing is certain, 5G technology will surely be ubiquitous, it will bring many positive changes to human beings. It is concerned that technology and flexible design, can surpass the previous generation of communications technology for different usage scenarios. "
Unlike the 3G and 4G eras, which emphasize more speed, Qualcomm designs the 5G as a universal platform. “We think that there are many aspects of fourth-generation technology that can be further optimized, so when we were developing 5G, the vision was opened up and more open. We are more from a research perspective, this technology is not just providing voice and The data also needs to have more capabilities, so we have put 5G technology as a communication module in the infrastructure of the entire human society and developed 5G as one of the most important social infrastructures.†Ke Shiya Global Network reporter said.
Cooperation is the key word for 5G development
In addition, Mr. Ke Shiya attaches great importance to the cooperation between Qualcomm and Chinese companies. In order to seize the commanding heights of 5G technology, a number of communications giants such as Qualcomm, Huawei, ZTE, and Ericsson have a strong interest in R&D for 5G, and they have invested heavily. Why do so many manufacturers scramble to compete?
Mr. Ke Shiya made a series of metaphors for Global Net reporters. “5G can be said to be similar to raw materials and it is very important in the whole society. This is why many companies cannot expressly express their specific investment in 5G. The reason, but everyone is aware that the 5G technology will have a profound impact. Just like the first manufacturer of elevators would not have foreseen that there will be so many skyscrapers in these metropolises."
Mr. Ke Shiya is obviously not worried about the competition. He said: “Like the Olympic Games, the athletes in the world will strive to make their best performance in the competition, which will push the limits of the entire human race forward. The result is beneficial to everyone. I am now in China, which once again proves the close cooperation between Qualcomm and Chinese companies. Indeed, this is true. On February 15 this year, Huawei and Qualcomm Vodafone and Vodafone jointly announced the world’s first successful LAA (Licensed-Assisted Access) commercial network in Turkey. According to reports, LAA is part of LTE Advanced Pro. In other words, Qualcomm is continuing to advance the evolution of 4G LTE at a solid pace and cooperates with Chinese companies to smoothly transition to 5G.
Of course, "cooperation" is also the key to domestic 5G development. The Ministry of Industry and Information Technology recently stressed that the joint promotion of the 5G industry chain at home and abroad and the strengthening of global cooperation are important guarantees for the maturity of the 5G industry chain. According to the reporter’s understanding, Qualcomm’s cooperation with domestic companies such as China Mobile in the field of 5G has also gradually improved. Earlier, China Mobile's 5G Joint Innovation Center and Qualcomm demonstrated the 5G NR prototype system below 6GHz. The prototype system operates in the 3.4-3.6 GHz band and can efficiently achieve multi-gigabit data rates and low latency per second. It is also one of the earliest implementations of 3GPP 5G NR key technologies in the industry.
Qualcomm is leading the next decade and the future of 5G. 3G and 4G connect people, and 5G will interconnect everything. Compared with previous generations of mobile technologies, 5G will become a more powerful unified architecture and will play a greater role in the future. It will become an important connecting layer that will be critical to our city, work, family and self, and will also be the foundation of the future technological revolution.
Realizing the vision of 5G needs to expand the boundaries of technological innovation
In this short-lived period in which reporters work, they have always believed that people are the foundation of everything. This makes reporters more curious about the scientists behind these technologies. What kind of people are people who have developed technologies that have a huge impact on humanity as a whole?
In the public's impression, most of the people who are engaged in IT work should be nerds like "nerds." But "What everyone knows" is that Mr. Ke Shiya not only has an engineer degree but also a philosophy degree. He, a scientist with liberal arts and sciences, told Global Network reporters: “I am interested in philosophy because I am interested in knowledge-related philosophy. For example, how do humans learn and how do they learn? How does the human brain function, what is the overall learning style and capabilities of the human society, and what adjustments it brings? There is no doubt that technology has played a role in thinking about these issues. The answers to these questions are all related to technology.Technologies are ubiquitous in human society and promote the transformation of human society. If you compare the historical evolution of human society, the function of the human brain, and the development process of technology, you will find these three There is a close connection between people."
Ke Shiya likes music very much. He is also a music critic while working. Ke Shiya told reporters that we must not let work occupy all of these things. These hobbies will allow you to let go of your work so that we can develop clearer thinking. Traveling along the Silk Road backpack gave Ko Shih-ya a more unique vision. In his opinion, “Silk Road is the neural network of the entire world and is the initial road connecting the East and the West in the history of mankind. From the point of view, we can only see things in 10 years, 15 years, 20 years, and up to 50 years from now.The retracing of the Silk Road can help me think about the time span that spans hundreds or even two thousand years. We always say that technological innovation is the constant development of innovative, virtual, and technological boundaries.In fact, in reality, we can also try to explore geographical, physical, and practical boundaries, and you will find this very interesting and very rewarding. â€
Perennial focus on the field of communications, not only allows Qualcomm to accumulate a large number of technical patents, Ke Shiya himself is also an inventor or co-inventor of more than 40 patents, Mr. Ke Shiya is extremely humble. He said: "Innovation is driven by team strength. I have access to more than 40 patents because I work with many very kind and intelligent colleagues and they are the driving force behind my innovation. In addition, Qualcomm’s corporate culture has always been It is also important to constantly promote innovation and self-improvement."
The large-scale commercial use of 5G technology is expected to be achieved by 2020, and on this communications highway, what will be an exciting trajectory for virtual reality technology, IoT technology, robotics, artificial intelligence, etc. Need to wait and see. And we believe that because of the exploration of so many outstanding scientists, humanity will eventually find a better world.
