It is a new generation of broadband mobile communication technology, which has the characteristics of high speed, low delay and large connection, and is the network infrastructure to realize man-machine interconnection.
The International Telecommunication Union (ITU) has defined three major application scenarios of 5G, namely, Enhanced Mobile Broadband (eMBB), Ultra-high Reliability and Low Delay Communication (uRLLC) and Mass Machine Communication (mMTC).
Enhanced Mobile Broadband (eMBB) mainly aims at the explosive growth of mobile Internet traffic, and provides a more extreme application experience for mobile Internet users. Ultra-high-reliability and low-delay communication (uRLLC) is mainly used in vertical industries that require high delay and reliability, such as industrial control, telemedicine and autonomous driving. Mass machine communication (mMTC) is mainly aimed at smart city, smart home, environmental monitoring and other application requirements for sensing and data acquisition.
Development history
20 13 In February, the European Union announced that it would allocate 50 million euros to accelerate the development of 5G mobile technology, and planned to introduce mature standards before 2020? .
20/kloc-in April of March, the Ministry of Industry and Information Technology, the National Development and Reform Commission and the Ministry of Science and Technology supported the establishment of IMT-2020(5G) promotion group as a platform for 5G promotion. The promotion group aims to organize domestic forces, actively carry out international cooperation, and promote the formulation of international standards for 5G. On April 2013 19, the first meeting of IMT-2020(5G) Promotion Group was held in Beijing. ? [ 1]?
20 14 On May 8th, Japanese telecom operator NTT DoCoMo officially announced that it would cooperate with six manufacturers, including Ericsson, Nokia and Samsung, and start testing a high-speed 5G network which is 0/000 times more than the existing 4G network, and the transmission speed is expected to increase to 100 Gbps. The outdoor test is expected to start on 20 15 and run in 2020? .
In June, 20 16, China's 5G technology research and development experiment was officially launched, and it was implemented on 20 16-20 18, which was divided into three stages: 5G key technology experiment, 5G technical scheme verification and 5G system verification.
