China has sounded 5G knock on the door

May 17, the World Day of Information and Communication, according to my statistics, the same day China's three major telecom operators showed more than 60 5G application to the public, including the 5G + AR panoramic view live, remote operation, remote signature, autopilot, interactive games , unmanned aerial vehicles and so on, has sparked public concern and strong experience of 5G expected.
5G with public expectations and increasing interest, China should accelerate the commercial 5G increasingly vocal. From the perspective of the maturity of the industry, the current 5G technologies and products have matured, systems, chips, terminals and other major aspects of the industry chain has basically reached the commercial level, it can be said with the conditions for commercial deployment.
People familiar with the history of the development of the mobile communications industry knows that define a generation mobile communications technology business has two basic conditions: First, the standard formal freeze, recognized the global mobile industry chain; the second is to complete the band allocation. About standards, June 13, 2018 officially frozen 3GPP R15 NR (independent network) standard, although the standard R15 Late Drop freeze delayed until this year, but 3GPP RAN chairman Balazs Bertenyi publicly expressed "This does not in any the first way affect 5G deployment, compatibility for the first deployment of equipment and networks are not affected. "
In-band allocation, the Ministry of Industry as early as December 7, 2018 made it clear that the three operators 5G test frequency: China Unicom obtained 3500MHz-3600MHz; China Telecom to get 3400MHz-3500MHz; China Mobile to get two bands: 2515MHz-2675MHz and 4800MHz-4900MHz. China is planning to carry out commercial network operators 5G cleared the basic obstacles, but also for the whole industry chain, from the chip to the terminal, to test instrumentation product development cleared the way.
Another fact about 5G with commercial deployment conditions, in the January 23, 2019, IMT-2020 (5G) to promote 5G technology research and development group, held in Beijing Phase III trial summary and the second "bloom Cup" 5G applications collection contest starts at the meeting, IMT-2020 (5G) to promote the group released the 5G technology research and development phase III trial results showed that: 5G base station and core network equipment can support non-independent networking and independent networking mode, the main function in line with expectations to reach pre-commercial level. This laid the foundation for the three operators scale testing and demonstration for the commercial preparation.
China's three major carriers to accelerate the arrival of scale trials of 5G. Since the beginning of 2019, the three major carriers have announced a pilot project, selected 17 cities in 5G-scale tests, a person familiar with the author scale operator trials told the author, on the whole, 5G non-independent networking ( NSA) test "good progress is expected to be basically completed in the near future, especially exchange between the base station and the terminal chip basically completed, in his words, is already" the NSA basic authentication technologies and products initial maturity. "
May 17, China Mobile announced already in 17 cities nationwide demonstration 5G around 31 scenes, and plans this year in more than 40 cities 5G network construction, speed up the pace of business. Earlier in April, China Unicom also announced plans 5G network that "7 + 33 + N" 5G plan; China Telecom have been carried out to expand the pilot SA + NSA hybrid network in Beijing and other eight cities, multi across many provinces 5G-scale field trial network of China Unicom.
We can see that China's three major operators are actively carry out pilot deployment 5G networks to prepare for the commercial 5G.
In this process, we need to have a clear understanding on several key issues in the commercial process 5G, 5G will be held on confidence in China's development.
First, the choice of 5G SA and NSA, the Chinese operators and operators around the world compared to a leading position. Public information display, China Telecom and China Mobile are already clear target SA will also select NSA promoted simultaneously. Only SA in order to meet the future needs of the industrial sector, smart city, and so on autopilot.
The second is the terminal price 5G, the current market price of the most open in 8000, the cost is still relatively high, but if we move from the development of communication Historically, early after the new technology out of the high cost of the terminal is natural, but with the maturity of the industry and accelerate network deployment, the terminal will be a rapid decline in the cost of the stage, China mobile to predict the end of 2019 5G terminal price will be reduced to 5,000 yuan, while the 2020 portion of 5G mobile phone prices may drop 1,000 yuan.
Third, the 5G network quality problems, we must first be clear two things: network deployment will take time, network optimization takes time. We can not expect to achieve immediate nationwide seamless coverage 5G, it is neither practical nor economical. In the progressive development of the network deployment optimization, the current problems, all will be resolved.
Fourth, energy consumption 5G network. Recently Ren said 5G 4G is 20 times the capacity, 2G ten thousand times, the power consumption decreased by 10 times. 5G is a first base station before the current generation, the next generation of mobile communications industry is developing products, about the use of higher power efficiency of the new materials, new algorithms, new functions, thereby significantly reducing power consumption value.
In addition, we also see that local governments are also actively promoting industrial electricity tariff reduction, some places have already landed, provided the basis for the 5G energy development.
Fifth, the application of 5G, 517 day operator display 5G sixty large application author pre statistics show that in individuals, families, three major areas of the industry, innovative applications 5G telecom industry has not only an industry thing, but the whole community to actively participate in all industries, such as China mobile jointly remote operation is an example of Huawei and union hospital carried out. The Chinese in the field of Internet video, games, maps, electricity providers and Chinese manufacturing, the wisdom of the city's transformation and development, but also provided a broad space for commercial and development of 5G.
To sum up, we can see that China has been on the road 5G commercial, environmental policies, standards, spectrum, technology and products are already available, provides the basic conditions for commercial deployment, as problems are problems in the development of It does not affect the nature
