Dr. Hou Jilei, senior director of R&D at Qualcomm and head of China R&D Center, said in an interview with C114 that 5G technology is crucial in the upcoming era of Internet of Everything. To this end, Qualcomm has a forward-looking layout that will not only lead the development of 5G from the standard level, but also promote the 5G process from the perspective of the ecological chain.
Hou Jilei said that in the transformation of the entire 5G technology, the communication-level technologies we usually talk about include intelligent computing, artificial intelligence, big data, and so on. But in fact, there is a very important part that is often overlooked by the industry, and that is information security.
Qualcomm: Leading the global 5G roadIn 2002, digital communications redefines the phone; in 2010, mobile technology redefines computing; today, we are moving toward the Internet of Everything.
According to authoritative forecasts, by 2018, global non-mobile networked terminals are expected to ship more than 5 billion. The Internet of Everything encompasses a variety of vertical areas and market segments, such as smart cities, healthcare, networking equipment, automobiles, smart homes, mobile computing terminals, and a wide range of wearable devices. It can be said that from 1G to 4G, communication technology mainly solves the communication between people; from 5G, communication technology will mainly focus on the communication between people and things, things and things, that is, the Internet of Everything. Since the current 3G and 4G technologies cannot provide effective and stable support, the real development of the Internet of Things is inseparable from the maturity of 5G technology and will become an important driving force for the development of 5G.
Hou Jilei pointed out that Qualcomm began to lay out the 5G strategy more than ten years ago and carried out preliminary research and development. Qualcomm, which is committed to innovation, has consistently invested heavily in technology research and development over the years, with cumulative R&D investment exceeding US$43 billion. This persistence enables Qualcomm to continue to lead the innovation and development of 2G, 3G, 4G, and even the 5G era.
“Qualcomm's work in the 5G field is more forward-looking, mainly in three aspects,†Hou Jilei said. “One is Qualcomm's advance layout of related technologies and the implementation of R&D projects. Standards are developed throughout 3GPP. In the process, Qualcomm, as an important player in the global wireless communication field, leads the whole standard orientation and standardization process. Second, in terms of 5G prototype, Qualcomm is starting from all frequency bands to target the diverse frequency bands. R&D and improvement. Third, Qualcomm has carried out very close early communication and deployment with important partners around the world, including operators."
4G will be with 5GIn the past 30 years, mobile technology has experienced unprecedented innovations and changes. From the 1980s to the present, we have experienced the transformation of mobile communication every 10 years, from early speech to later digital to image, video and other stages. . These innovations have gradually changed the way people live and communicate. From the perspective of the vision, the next decade will be the 10G development and growth until the mature decade, it will establish a future-oriented, innovative, unified connection platform.
Hou Jilei mentioned that 5G technology has been accelerating development from the perspective of standardization or industrialization. 5G proposed a new concept, that is, multiple connections. It enables each terminal to achieve effective real-time connection with multiple networks and multiple frequency bands at any time, not just with a network or a frequency band. From the perspective of speed, connectivity and reliability, 5G surpasses previous 3G and 4G technologies.
However, 4G technology itself has a strong vitality. In the development of communication technology, 4G technology has played a very good coverage for the construction and early deployment of 5G systems. Therefore, 4G technology will complement and develop with 5G technology for a long time.
5G should pay more attention to information securityThe coming of a new generation of technological change is the time to break through the rules and break through the boundaries. In this regard, Qualcomm Hou Jilei pointed out that there are still two problems in 5G technology that need to be broken. One is the mobile millimeter wave technology in the case of non-line-of-sight, that is, how to ensure the efficiency and robustness of signal transmission in the case of non-line-of-sight. Second, whether it is millimeter wave or other frequency bands, if the rate is to reach gigabit, or even several gigabit, it will pose a big challenge to battery power consumption.
In addition, Hou Jilei also mentioned that in the whole revolution, the communication-level technologies we usually talk about include intelligent computing, artificial intelligence, big data, and so on. But in fact, there is a very important part that is often overlooked by the industry is information security. In the development of the entire Internet of Things, including artificial intelligence, information security is the next step worthy of attention. If information encryption can be performed through multiple modes of integration, such as security authentication execution, or behavior analysis, or even by introducing deep learning methods to early anticipate this hacker attack mode, technical security can be protected and enhanced at the terminal level. Hou Jilei believes that this model will establish a very important firewall for direct information security. In the future, the firewall will not only be in the cloud, but also in the terminal.
In fact, Qualcomm has developed a good layout in terms of product technology security. For example, Qualcomm's Opteron chip uses a concept called Trustzone, in which a part of the chip can isolate and encrypt data authentication and access, which is equivalent to "safe island". Hou Jilei emphasized: "In the future, Qualcomm will continue to strengthen its thinking and layout in terms of technology security, and promote the development of technology security. The technology of terminal encryption may also advance from software to hardware, thereby further improving work efficiency."
