At the conference, first-line scientists and technical experts from famous scientific and technological innovation enterprises such as Huawei, Baidu, Aliyun, Lenovo and 360 shared the ongoing changes in the world with the general public, depict the picture of a smart world and make the common people know more about where we are The era of intelligent origin. The following is Dr. Ji Ji Lei speech: Hi everyone, I am very pleased to have the opportunity to share with you some of the 5G Qualcomm Imagine. Artificial intelligence is a hot topic, and Qualcomm has been in the field of connectivity, computing and other fields to promote the development of the entire industry. Well, I share some of the vision and opinions of Qualcomm on artificial intelligence today from a connection perspective. Over the past 30 years, mobile technology has undergone unprecedented innovation and change. From the 1980s to the present, we have experienced every 10 years of mobile communications revolution, from early voice to later digital phases, to images, videos, etc. . These changes have brought a series of changes to the way of human life and communication. Today we are in the stage - 4G, which we often say LTE-Advanced era, its colleagues in helping the development of the mobile Internet, but also make a significant contribution to the connection. As a member of the communications industry, we are very proud that Qualcomm has brought about many changes in human life. Many people have heard of the term 5G, then what is 5G? From a vision point of view, it is to establish a future-oriented, innovative and unified platform for connecting, mainly in the following three aspects: First, 5G can facilitate the new fusion of different spectrum bands and spectrum types from 1 GHz to 50G, 60G even 100G Hz wide spectrum, 5G can provide very good support. In addition, we often mention the cellular connection, in fact, more focused on the licensed spectrum, and in the future, 5G to achieve unlicensed spectrum, shared spectrum development and integration. The second is the unity of 5G. This is reflected in the diversified services, mainly including three aspects, 1) to enhance mobile broadband. For example, to make the virtual reality or high-definition remote technology to achieve mobility, 5G is an indispensable way to achieve the connection. 2) Key business services. For example, in the area of ​​autopilot, cars and vehicles are connected by sensors. This connection between the car and the car, the need to integrate the sensor connection. This also shows that 5G technology is an important auxiliary way to make the driverless. 3) massive Internet of things. The honored guests should have more understanding of this part. Smart home, smart city, smart wear, etc., are used 5G technology. How to make a large number of devices seamlessly and massively integrate into society is an important task to be accomplished by 5G. In our opinion, the most important point of 5G is to bring an immersive experience to everyone from the perspective of enhanced services. The video you just played shows virtual reality and augmented reality, the fusion of VR and AR in the future. The protagonist in the video experiences AR on the scene. Although his best friend is not at the scene at home, he can directly feel his good friend on the scene through VR. Through 5G technology, these two kinds of experience in the future can be achieved fusion. If you want to support this enhanced mobile broadband, what needs to be done in the 5G area? I have listed here a few important indicators: First, at the transfer rate, we have to be able to achieve gigabit per second data rate. For example, today, 4G network speed has been quite fast, but 5G may be several times faster than the 4G connection speed, a hundred times or more. In addition, if you want to achieve the effect of real-time virtual interaction between virtual reality and real environment, it is very important to achieve ultra-low latency (reduce latency to 10 or even 1 millisecond). This slide outlines some of the technologies we think are more important, one of which is massive MIMO (Multiple Inputs and Multiple Outputs). MIMO is changing from an antenna perspective. From the base station to the terminal, we use a large number of antennas to improve the coverage area and data volume. Second, we propose a new, transformative concept that introduces millimeter waves, especially mobile millimeter waves, into 5G technology. How non-line-of-sight conditions make millimeter-wave performance a good indicator of how 5G is a transformative innovation. Third, from a spectrum point of view, in the 3G and 4G phases, licensed spectrum is more used. In the future, 5G technology will introduce unlicensed spectrum, and even share spectrum, to achieve convergence of spectrum usage and promote efficiency improvement . Second, in addition, 5G will provide good support for key business services, mainly in areas such as healthcare, public safety and industrial internet of things. In just the video, the scene is public safety. When a fire occurs in one place, how to achieve real-time effective fire prevention and command control through the UAVs in relatively remote places is an important experience for the application of the future 5G technology. To support the above key business services, 5G provides the following three kinds of support: 1) high reliability. For example, high-reliability assurance in areas such as public safety, industrial internet of things, and precision manufacturing are important. 2) ultra-low latency. If you want to control drones and industrial equipment in real time, keeping the delay within 5 milliseconds or even a millisecond is also important for real-time operation to improve future productivity and ensure public safety. 3) The realization of critical business services requires a wide range of technical support. Here to introduce two more important concepts: The first concept is the network slice. When enhanced mobile broadband is introduced into the key tasks of the industrial Internet or public safety field, it is necessary to ensure that network resources, such as terminals, can be allocated dynamically, real-time and effectively from the core network to the access network to ensure quality. When Delay, speed, broadband and other aspects of business quality. The second concept is multi-connection. It manifests that each terminal can effectively connect with multiple networks and multiple frequency bands in real time at any moment, not only one network or one frequency band. From coverage speed, connection, reliability point of view, it surpassed the previous 3G and 4G technologies. Third, 5G technology will enable the future massive Internet of Things connection. 5G technology is mainly used in smart home, smart city, and massive industrial Internet of Things in the video just Massive Internet of Things. Many authoritative agencies and magazines have made predictions that by 2020 there will probably be 50 billion devices in the community that will realize the massive Internet of Things through the connection of people, things and things. This slide shows the possible appearance of a smart city in a very dense urban area, such as China and the United States. This includes monitoring air quality, public Wi-Fi access information, and information monitoring. All of the above will profoundly change the way people live and communicate with each other in the future. Therefore, we think that 5G will play a very good supportive role for the massive Internet of Things. In the field of massive things, the following points need to be emphasized: one is high power efficiency. To reach mass connections of tens of billions, many devices and modules need to last five, 10, or even 15 years without replacing the battery. Therefore, how to ensure high efficiency, low power consumption is very important. The second is the depth of coverage. For example, there is a sensor that decays very quickly inside a building or underground. For example, in China or Europe, many buildings are reinforced concrete, resulting in especially weak coverage of this sensor. How to make this kind of sensor realize the chain computation and signal depth to cover through employing 5G technology, this is 5G compared with 3G and 4G too. Just now, I briefed the guests on the 5G's new changes that will bring about the future of society and services. Next, I will briefly introduce Qualcomm's efforts to achieve 5G development and industrial chain cooperation. First of all, Qualcomm believes that the future development of 5G should be considered from the following three aspects. The first one is to break through barriers and borders. This is manifested in many aspects, such as laws and regulations, and technical aspects. For example, some people may wonder that today's 4G network is already very good, why do we still need 5G? Ten years ago, when we moved from 3G to 4G, others raised the same question. From ten years ago to today, smartphones have shown a thriving and explosive process. So, today we should innovate from 5G technology too. So, how to break barriers and borders? The first aspect is the spectrum we just mentioned. In the future, licensed spectrum will be shared and deeply blended with unlicensed spectrum. So from a legal and regulatory point of view, how to work with industry and government to promote such a vision has become an important manifestation of breaking through the border. The second aspect is from a technical point of view, including devices and equipment development process. The millimeter waves we talk about today, reaching gigabit per second, the need to improve device technology and reduce battery power consumption, these technical challenges and boundaries require us to face and break through. The third area is that we need to build advanced and reliable 5G settings. Many of the concepts are novel when we push the 5G setup. However, the realization of these new concepts in the process, whether to ensure the feasibility, reliability and robustness, whether to ensure that users bring innovative experience, but also the development and design of the future 5G an important aspect. The fourth aspect is technical support. This technology should be able to support a global and non-fragmented deployment, play a unified role. This includes the selection and unification of future standard technologies, the unification of operators' bands, and the unification of devices. How to prevent fragmentation, promote the development of the unified, promote the standardization of the industrial chain, are the areas of concern in the 5G topic.
