Developing 5G communications requires testing first

"The 5G era is coming. China is seeking to 'lead' the world, and we are also seeking to 'lead' China." On July 19, the reporter walked into the 41st Research Institute of China Electronics Technology Group located in the High-tech Zone of Bengbu City. In the product exhibition hall, senior engineer Zhang Yu showed reporters the great changes that 5G communication technology will bring to people's lives through systems such as 3D naked-eye video, high-speed high-definition video surveillance, and IoT smart home security monitoring.

"5G, the fifth generation of mobile communication technology, is the latest generation of wireless communication technology after 3G and 4G." Zhang Yu introduced that as "Internet +" profoundly changes people's lifestyles, people have put forward higher and higher requirements for information exchange and transmission. 5G mobile communication technology, with its high speed, large capacity and super connection, responds to this demand. In 2016, my country fully launched the 5G technology research and development test. On December 27, 2016, the State Council officially issued the "13th Five-Year National Informatization Plan", proposing to carry out 5G network technology research and development and testing in 2018, accelerate the promotion of 5G technology research and industrialization, and promote the formation of a global unified 5G standard. "A trillion-level sunrise industry is being nurtured." Zhang Yu believes.

Equipment development requires testing first. As the world's fourth largest test instrument manufacturer and the only professional electronic measuring instrument research institute in my country's defense science and technology industry system, China Electronics Technology Group Corporation No. 41 Institute has witnessed the leap from "2G follow-up" to "3G breakthrough" and then to "4G synchronization" in my country's mobile communications field. As early as 2014, the No. 41 Institute began to focus on the research and development of 5G cutting-edge technologies and the formulation of specifications. It can be said that China Electronics Technology Group Corporation No. 41 Institute is at the forefront of the industry.

In 2015, China Electronics Technology Group Corporation 41st Institute, together with China Mobile, Rohde & Schwarz China Ltd. and three other global leaders in wireless communications, jointly released a 5G testing white paper, providing guidance for the development of the entire industry and becoming one of the setters of industry standards.

In front of the "3D high-definition video transmission system", Zhang Yu patiently explained to reporters: the data transmission capacity of 5G communication network is several times or even dozens of times that of 4G. The high transmission rate of 5G network ensures that people can still watch 3D videos remotely without naked eyes. "In the near future, people can watch 3D live football games at home, and they can be immersed in the scene without going to the scene."

In front of the "High-speed Railway Communication Simulation and Analysis System", Zhang Yu told reporters that this system is used to test the mobile communication quality of the 5G communication network under high-speed mobile conditions. "Maybe by 2020, when people are riding on high-speed trains, they will not be stuck when watching videos with 5G."

In front of the "5G IoT Smart Home Security Monitoring System", the on-site staff opened an App on their mobile phones to monitor the doors and windows, lights, fire warnings, gas, water and electricity switch status and operation in a simulated house, and realized remote control. He told reporters that this is to monitor the access of massive data under the 5G network. Under ideal conditions, every grain of sand in the desert is equipped with a detector, and the 5G network can track and monitor it.

"Unlike the existing 2G, 3G, and 4G technologies, the 5G communication network will have a greater demand for 5G communication testing services. 5G communication testing is the direction with the largest market share and the fastest development in communication testing." Zhang Yu believes that this is because 5G communication technology is more complex. At the same time, as the 5G mobile broadband network realizes the interconnection of all things, the demand for corresponding test equipment such as base station simulators, terminal simulators, RF consistency, RRM consistency, MIMO, and MassiveMIMO channel simulators is becoming more and more extensive. During the interview, the reporter learned that in addition to 5G communication test instruments, China Electronics Technology Group Corporation No. 41 is also building 5G communication core components based on years of technical accumulation, including T/R components, multi-channel power amplifier components, multi-frequency filter components, switch components, etc. "We hope to rely on the technical advantages and talent advantages accumulated over the years, and focus on the layout of 5G communication core components, 5G communication test instruments, 5G dedicated networks, etc., in the good situation of the country's promotion of the development of a new generation of broadband wireless mobile communication technology, to create the Anhui Province Economic Circle of the 5G communication industry, and provide a new economic growth point for the rapid economic improvement of Anhui Province." The main person in charge of China Electronics Technology Group Corporation No. 41 said.
