[Preface] From 2G to 5G, from no independent intellectual property rights to partial mastery, and then to master all the core technologies of wireless communication, and then participate in leading communication standards, master the right to speak in the formulation of 5G standards. How will 5G change people's lives? In the context of accelerating the development of 5G technology around the world, can China achieve 5G leadership? With these questions, the reporter recently interviewed Sun Xiaonan, executive vice president of Datang Mobile.
The first step in competing for the 5G commanding height is to set standards.
“The first-class enterprise is the standard, the second-rate enterprise is the brand, the third-rate enterprise is the product, and the first step to compete for the 5G commanding height is to formulate the 5G standard.†Sun Xiaonan introduced that the standard is an industry-recognized, reusable specification. If there is no mobile communication standard, the mobile phone will not be able to make calls and will not be able to roam globally or access the Internet. Whoever dominates the communication standard, whoever dominates the right to speak in industrial development, who dominates the autonomy of information security. Sun Xiaonan said that according to the timetable announced by the 3GPP, the first version of the 5G standard (3GPP RELEASE 15) will be completed in September 2018. The standardization and industrialization of 5G has entered the sprint phase.
5G realizes technological innovation in industries such as telemedicine
Download 30 movies in one second, which is the most intuitive experience of communication networks in the 5G era. However, the research and development of 5G is not only for the communication industry, but also helps to realize the combination of 5G technology and industry technology to help the industry upgrade.
With the coming of the 5G era, telemedicine based on 5G networks will have profound changes in the medical status quo in rural areas. Car assisted driving is currently being applied. The car predicts collisions in advance by sensing peripheral obstacles. By sensing the automatic action, 5G will help assist the driver to get better and accept the instructions at a faster rate. The 5G feature will also be used for driverlessness, and the fast response provided by the 5G network can assist with self-driving cars.
5G will be integrated with industry technology
In addition, Sun Xiaonan told reporters that 5G wide coverage, low power consumption and large connections will be combined with industry technology. The reporter learned that if 5G is used in agricultural greenhouses, it will help to achieve precise and intelligent irrigation. The intelligent irrigation of agricultural greenhouses mainly makes timely irrigation by sensing the temperature, humidity and pressure in the greenhouse. However, due to the limitation of the network speed bandwidth, the number of sensors in the shed cannot be installed too densely, otherwise it will affect the network speed. However, sensor density can affect the accuracy of the data. In the 5G era, the need for increased sensor density can be addressed.
Datang builds the world's largest 5G multi-scenario test network
In Sun Xiaonan's view, 5G has gone from "vision" to "getting closer". According to reports, 5G from concept to application generally needs to go through three stages: the technical research stage (that is, the target stage of constructing 5G communication standard), the technical test stage, and the technical commercial stage.
Sun Xiaonan introduced that based on years of key technology research and development advantages and network construction foundation, Datang has also carried out a comprehensive layout for the fifth generation mobile communication technology standards. In September last year, Datang announced that it successfully completed all the tests of the first phase of the wireless part and the network part, focusing on technical tests such as large-scale antennas, new multi-access, and ultra-dense networking. Among them, the ultra-dense networking scenario is only tested by Datang, and it is also the only experimental environment that has been built in China, which fully verifies the support capability of 5G for ultra-high traffic density.
This year, Datang will enter the second phase of 5G technology research and development test, and lead the construction of a 5G field test environment to support the construction of the world's largest 5G test network in Huairou, Beijing. Sun Xiaonan introduced that this is also the world's first 5G test network that can be used to test multiple scenarios.
Not long ago, in the Huairou test field, Datang launched the Datang 5G Industry Partner Program, and cooperated with the Chinese Academy of Sciences, Qualcomm, Intel, Keysight, China Automotive Engineering Research Institute and other industrial chain multi-link partners to actively build terminals. 5G industry ecosystem such as chip, network, business application, test instrument, etc., to build 5G industry international alliance, promote the rapid maturity and rapid deployment of 5G industry, and seize the strategic commanding height of 5G industry development.
This year, Datang entered the second phase of 5G - technology research and development test, and led the construction of a 5G field test environment to support the construction of the world's largest 5G test network in Huairou, Beijing. The picture shows the Datang technicians testing the 5G test terminal prototype at the 5G test release conference held by Datang in 2016.
