On July 22, Zhang Feng, spokesperson and chief engineer of the Ministry of Industry and Information Technology, said at the press conference of the State Council that the Ministry of Industry and Information Technology will increase the research and development of 5G (fifth generation mobile communication technology). When people are still talking about 4G, 5G is ready to go. How to understand 5G? For the average consumer, downloading an 8G HD movie takes 70 minutes in the 3G era, 7 minutes in the 4G era, and only 6 seconds in the 5G era.
Experts predict that by 2020, 5G will be commercially available. China has experienced the accelerated development of 1G blank, 2G follow-up, 3G breakthrough, and 4G synchronization in the field of communication technology standards, and strives to gain a dominant position in the 5G era. For the market, 5G means more opportunities. Although it will take several years for real commercial use, 5G has become a global focus.
China's 5G standard is expected to become the world standard
5G, popular speaking, is the fifth generation of mobile communication technology, but unlike 4G, 3G, 2G, 5G is not an independent, new wireless access technology, but for existing wireless access technologies (including 2G, 3G) , 4G and WiFi) technology evolution, and some new integrated solutions for complementary wireless access technology integration solutions. To some extent, 5G will be a true fusion network. Provides high-speed, secure and free communication between people, people and things, and things and things with a standard of integration and unity.
From a professional point of view, in addition to ultra-high-speed transmission requirements, 5G also needs to meet the requirements of large bandwidth, ultra-high capacity, ultra-dense sites, ultra-reliability, accessibility anytime, anywhere. Therefore, the communications community generally believes that 5G is a broadband, ubiquitous, intelligent, convergent, green and energy-efficient network.
The future development direction of the 5G-based mobile broadband network is to create a platform of “mobile intelligent terminal + broadband + cloudâ€, which, like other energy and public utilities, has become the basis for the entire society and various industries to operate. Accelerating 5G research and development will help China to stand in the forefront of the future data wave competition and take the lead. In 2013, the Ministry of Industry and Information Technology led the establishment of the MG2020 promotion group, officially launched the research work of China's 5G standardization, and some domestic enterprises have also actively carried out 5G research and development. After China Mobile's 2G follow-up, 3G breakthrough, and TD-LTE (domestic 4G) lead the development, China Mobile's technology will usher in a great opportunity for 5G R&D.
Cao Shumin, dean of the Institute of Telecommunications Research, Ministry of Industry and Information Technology, said that since the 5G technical standards will achieve global unification, there will be no standard disputes in the 3G and 4G eras. China is actively participating in the formulation of 5G international standards. Enterprises in the patent research and development, product development, global promotion and other aspects of further efforts to establish strategic advantages.
Industry experts said that the rise of China's mobile communication technology will change the pattern of the world's communications industry, China's 5G standard is expected to become the world standard in the 5G era.
5G trial commercial network will be launched in 2018
Chinese and foreign communication manufacturers have stepped up their efforts in the layout of 5G. Ericsson is currently demonstrating 5G technology in real-time in a wireless environment, achieving a 5Gbps per second throughput rate on the 15GHz spectrum. Huawei and Japanese carriers opened the world's first multi-user 5G technology verification field in Chengdu, systematically verifying 5G air interface technology and network architecture. It is understood that Huawei, ZTE, Datang Telecom, China Mobile and other Chinese companies are committed to the research and development of 5G technology standards, and the overall investment is considerable.
China Mobile Chairman Qi Guohua said that China Mobile is currently carrying out related work in the market, technology, spectrum, and industry construction. In the future, it will continue to promote research on 5G related aspects, including the formulation of 5G related standards, preparation for future trials, product development, and Pre-commercial, etc.
At the World Mobile Communications Conference (MWC) held in Shanghai recently, Huawei announced the 5G promotion schedule, which will focus on 5G standardization before the end of 2018. In 2018, it will be the first to jointly launch a 5G trial commercial network with partners, and promote the industry in 2019. The chain is perfected and the interoperability test is completed. It will be officially commercialized in 2020. Huawei has made breakthroughs in various fields such as networking architecture, spectrum usage, air interface technology, and base station implementation. According to reports, in terms of 5G spectrum, Huawei 5G system supports full spectrum, which supports core access bands below 6GHz, and will also support extended bands higher than 6GHz. High-frequency can be used for access and backhaul, through high-low frequency hybrid networking. Get the best spectrum utilization.
In fact, ZTE launched the Pre5G earlier. "Now 4G is so tight, can we use the 4G mobile phone unchanged, the 4G frequency and bandwidth are unchanged, and the 5G technology is used, the spectrum efficiency of the current base station is increased by 4 to 6 times. So ZTE launched It is called Pre5G. ZTE has gone a little earlier and is a little faster," said Liu Peng, vice president of ZTE Corporation.
With the 5G network, "what you want"
Shang Bing, deputy director of the Ministry of Industry and Information Technology, said that China's 4G is currently developing rapidly. In just one and a half years, China has built the world's largest 4G TD-LTE commercial network, covering more than 300 cities across the country, and more than 900,000 base stations. More than 200 million households. At the same time, our industrial chain is more mature. TD-LTE has formed a relatively complete industrial chain consisting of well-known enterprises at home and abroad, such as system equipment, chips, terminals, and test instruments.
While 4G is still developing rapidly, people can't help but think about what will happen to 5G in the future? According to media reports, South Korea will launch 5G services in the 2018 Winter Olympics, and Japan will launch 5G services in the 2020 Summer Olympics. Japanese operator NTT DoCoMo has begun to organize manufacturers to conduct technical evaluation and verification. The EU has been a very important and active force in promoting the development of 5G. The 5G PPP research project initiated by the EU has also been officially launched. China has also set clear targets for 5G development. The IMT-20205G promotion group was established as early as 2012, and a white paper on 5G wireless technology and 5G network architecture was released in May this year.
According to EU statistics, there are more than 1.2 billion mobile broadband users worldwide, and global mobile Internet traffic will increase by more than 30 times by 2020. The wireless capacity of 5G networks will be 1000 times higher than the current level, with the ability to serve 7 billion people. In such a huge market, there are boundless business opportunities and possibilities.
The application of 5G is not just a phone call. The first solution in the 5G era is the Internet of Everything, and the integration of information in various industries. This means that the 5G standard is no longer just a matter of the mobile communications industry. At this year's Shanghai World Mobile Communications Conference, Huawei staff introduced that with the 5G network, people can achieve the "what you want" through the machine, which also creates more possibilities for Industry 4.0 and precision manufacturing.
