In three steps, domestic 5G users will reach 100 million!
The development of technologies such as 5G, Internet of Things, and artificial intelligence will accelerate the society to enter a new era of Internet of Everything, and present three characteristics of connection ubiquity, perceptual ubiquity and intelligent ubiquity.
China Mobile Chairman Shang Bing said that China Mobile is accelerating the development of 5G. In 2017, China Mobile will conduct 5G system field trials in 5 cities, scale trials in 2018, pre-commercialization by 2019, and commercial scale by 2020. At the same time, it will strengthen joint research and innovation, further strengthen the key technology research and standard leading work such as 5G, and create a batch of 5G cross-industry innovation applications that can be promoted and promoted.
China 5G development schedule
China has established the most authoritative organization IMT-2020 (5G) promotion group (unlike ITU's IMT-2020 organization) responsible for the research and development of 5G standards, which organized the world's first 5G seminar and proposed " The 5G Flower was accepted by the ITU, and white papers such as 5G network architecture, 5G wireless technology, and 5G vision were released, and the time trials for commercial trials in 2018 and full commercial use in 2020 were determined.
The IMT-2020 (5G) promotion group unites three major operators, and major equipment manufacturers such as ZTE, Huawei, and Datang actively promotes 5G technology verification and standard setting, and divides the overall technical verification research and development into three steps. The first step is the 5G key. The technical verification has been completed and the 5G technical solution verification of the second step is currently underway.
Matz Granley, the authoritative industry organization in the global mobile communications industry and director of the Global System for Mobile Communications Systems, predicts that there will be 1.1 billion 5G connections worldwide by 2025, a large part of which will come from the Asia-Pacific region. Among them, the number of 5G users in China will reach 100 million.
In 2015, the International Telecommunication Union ITU defined three main application scenarios for 5G: Enhanced Mobile Broadband (eMBB), Large Connected Internet of Things (mMTC), and Low Latency High Reliable Communication (uRLLC). According to the "5G White Paper" released by the Future Mobile Communications Forum, it is divided from different perspectives of information interaction objects. The eMBB scenario refers to the further improvement of user experience and other performance based on the existing mobile broadband service scenarios. The ultimate communication experience with people, corresponding to large-capacity mobile broadband services such as 3D/Ultra HD video; mMTC and uRLLC are the application scenarios of the Internet of Things, but their respective focuses are different: eMTC mainly reflects between objects and objects. Communication needs, for smart cities, environmental monitoring, intelligent agriculture, forest fire prevention and other application scenarios targeting sensing and data acquisition; uRLLC applications have extremely high requirements for time delay and reliability, such as vehicle networking, industrial control Special application requirements for vertical industries.
Compared with 4G, in addition to continuing to strengthen the mobile broadband communication eMBB, it has also added two scenarios: massive machine communication mMTC, ultra-high reliability and low latency communication uRLLC: in the 5G era, in addition to human-to-human communication, it has also been added. The intelligent interconnection between people and things, things and things has opened up a huge number of terminal connection markets, while adding high-definition video, VR/AR, car networking, smart city, driverless, drone network, large-scale Internet of Things, etc. Various application scenario markets. Continue to strengthen mobile broadband communication between people, it is expected to appear video calls, holographic video calls, VR / AR interaction and other applications.
Mobile communication technology can be said to have emerged from the date of the invention of radio communication. The development of modern mobile communication technology began in the 1920s and has gone through five stages of development.
The fifth phase began in the mid-1980s. This is the period of development and maturity of digital mobile communication systems. This stage can be further divided into 2G, 2.5G, 3G, 4G, 5G and so on.
Mobile communication has a new generation of technology every ten years, and constantly introduces innovative technologies to promote the rapid improvement of overall performance. As 4G has entered the scale of commercial use, 5G for 2020 and the future has become the focus of research and development in the global industry.
