In 2018, the world will usher in the 5g era. China's three major operators will carry out 5g pilot in 12 cities, including beishangguangshen, Hangzhou, Wuhan, Chengdu, Tianjin, Nanjing, etc. in 2019, 5g mobile phones will be available. At that time, we may need to replace them. I believe many people are very curious about the difference between 4G and 5g?
The change that
On February 26, 2018 World Mobile Communication Conference opened in Barcelona, Spain, with about 2300 enterprises from all over the world participating. At this conference, 5g technology became the focus.
At this conference, Huawei released the first 5g commercial chip, which took the lead in breaking the commercial bottleneck of 5g terminal chip, while ZTE launched a new generation of 5g full range of base station products. Many related enterprises have disclosed that 5g mobile phones and other related terminals will be available in 2019.
In addition, on the evening of February 26, the reporter of the daily economic news (micro signal: nbdnews) learned from China Mobile that the field test will be carried out in five cities. In 2018, more than 100 5g base stations will be built in these five cities for 5g scale experiment. So far, China Mobile, China Telecom and China Unicom have announced their 5g pilot cities, totaling 12 cities.
The 12 cities will take the lead in using 5g
On the evening of February 26, the reporter learned from China Mobile that it will carry out field tests in five cities, Hangzhou, Shanghai, Guangzhou, Suzhou and Wuhan. In 2018, more than 100 5g base stations will be built in these five cities.
Previously, the reporter of daily economic news (wechat: nbdnews) learned exclusively from China Unicom that Unicom planned to conduct 5g test in 7 cities including Beijing, Tianjin, Shanghai, Shenzhen, Hangzhou, Nanjing and xiong'an, and has submitted an application to the Ministry of industry and information technology. In the future, the number of pilot cities will be increased according to the requirements of the Ministry of industry and information technology and the national development and Reform Commission.
China Telecom also told reporters that it has launched 5g pilot projects in six cities including Chengdu, xiong'an, Shenzhen, Shanghai, Suzhou and Lanzhou. There are 12 pilot cities integrating the three operators, of which Shanghai is the only one with all three operators.
The choice of pilot cities is not random. Huang Yuhong, vice president of China Mobile Research Institute, said that in terms of scale test, China Mobile chose to launch in five cities with developed economy (often ranking in the top 10 in terms of GDP), convenient transportation and high population density. It needs to involve 26 application scenarios, covering urban, dense urban, suburban, lake, urban village and other scenarios, and build a 20 square kilometer Internet of vehicles area.
The reporter learned from China Mobile that in addition to the five pilot cities, 5g business and application demonstration will be carried out in 12 cities including Beijing, Chengdu and Shenzhen, mainly covering 4K HD, augmented reality, virtual reality, UAV, etc.
According to the notice of the national development and Reform Commission, relevant enterprises carry out 5g network construction in no less than five cities in the application of 5g communication Demonstration Project in the frequency band below 6GHz, with no less than 50 5g base stations in each city, forming a continuous coverage in dense urban areas, with no less than 500 5g terminals in the whole network; provide users with no less than 100Mbps, millisecond class delay 5g broadband data service.
On February 23, the official website of the national development and Reform Commission released the list of projects to be supported for the construction of new generation information infrastructure in 2018. Among the eight projects, the 5g scale networking construction and application demonstration project of three major operators is listed. At the beginning of this year, the third stage specification of 5g technology R & D test was officially released. Through the third stage test of 5g technology R & D test, it is expected that by the end of 2018, the main links of China's 5g industrial chain will basically reach the pre commercial level.
