There are more and more Chinese netizens using mobile devices to access the Internet. In 2016, 92.5% of people used their mobile phones to access the Internet, which was 2.4 percentage points higher than in 2015. According to the latest data from the National Bureau of Statistics of China, there were 1.3 billion mobile phone users in China last year. More than 940 million or about 71% are mobile broadband users. This is 234 million more than in 2015. According to the Ministry of Industry and Information Technology, mobile phone users using 4G networks doubled last year to 770 million (nearly 60%).
The deployment of some new measures and new policies, such as increasing the speed of the network, allowing the sharing of traffic and saving unused traffic, will ensure the continued large-scale growth of 3G and 4G users in China.
At present, China Mobile has cooperated with major service providers and global telecommunications companies in China to deploy 5G technology.
In the 13th Five-Year Plan, China proposed that it should actively promote 5G development and launch the technology by 2020. The objectives of the plan include:
-- Promote the development of 5G key technologies.
- Verify and improve the 5G technology solution.
-- Supporting the globally unified 5G standard.
In order to achieve these goals, China has established cooperation mechanisms at the level of government and industry associations with Europe, the United States, Japan, and South Korea. Participants will include top telecom equipment vendors from Ericsson, Nokia, Huawei and other countries, as well as US chip makers Qualcomm and Intel. In addition, the participation of General Motors, Volkswagen and Haier Group indicates that 5G technology will have a broad mobile application.
5G minimum requirementsIn February of this year, the International Telecommunications Union issued a draft that first defined the definition and guidelines for 5G technology. The report also sets minimum requirements for 5G mobile antennas.
Compared to 4G, the 5G network speed will be much faster. For example, according to the minimum technical performance requirements, the peak data rate of a mobile station will have to reach 2.5 GB/sec downstream and 1.5 GB/sec upstream. Specific to the user experience, the downlink speed must be at least 12.5MB / sec, up 6MB / sec.
However, the biggest impact of 5G on users is latency and connection speed, which will greatly enhance the user's mobile Internet experience. In a 5G network, the acceptable delay is up to 4 milliseconds, which is a big step forward for a 4G LTE connection with a maximum latency of 20 milliseconds.
In the coming months, the International Telecommunication Union will evaluate the above draft and finalize it. Once it becomes a standard, manufacturers will begin mass production of 5G smartphones.
China's 5G testThrough the Ministry of Industry and Information Technology, the Chinese government has planned two phases for the 5G trial, namely, the technology development phase from 2015 to 2018 and the product development phase from 2018 to 2020.
It is estimated that China's major telecommunications companies will invest about 300 billion yuan in the project.
Currently, the first two steps of the first phase have been completed and the third step has just begun. Qualcomm, ZTE and China Mobile have plans to conduct collaborative testing and outdoor testing of 5G radio specifications.
At present, China Mobile has completed the development of basic technology, and aims to launch 5G commercialization services in some regions by 2018, and will upgrade its 1 million 4G base stations in the next year to meet the new standards. China Mobile also plans to launch 5G services nationwide by 2020. The trial will use prototype equipment from Qualcomm and a base station solution from ZTE to follow China Mobile's guidelines.
Future Application of 5G Technology (Internet of Things)The deployment of 5G networks is likely to accelerate the development of new services as it makes the adoption of the Internet of Things possible. Companies will be able to more easily centrally control multiple industrial robots and improve equipment maintenance by using big data analytics to identify potential failures.
The lower latency and higher bandwidth of 5G networks will be a key element in the development of virtual reality gaming platforms. For example, Facebook, which has invested billions of dollars in virtual reality, the company's CEO Mark Zuckburg believes that virtual reality will become a 5G "killer app." He also hopes that the next generation of wireless communication standards will help him recover his previous investment.
High expectations for 5G also include car manufacturers. For smart cars and connected cars to work, they will need a more powerful wireless network than 4G LTE. Thanks to low latency, 5G allows vehicles to transmit data and information in seconds, even at very long distances. In this way, the smart car can always receive information about the surrounding environment and then propose solutions through its artificial intelligence technology.
The 5G will also reduce traffic lights in the future, as the car will automatically decelerate at that time, avoiding traffic jams and accidents.
in conclusion5G technology seems to revolutionize society. Its potential is amazing and there are endless ways to apply it in the future. However, to develop a globally unified 5G standard, China's approach is clearly critical.
Right now, China and other industrialized countries are accelerating 5G development, although a better option may be to focus on expanding the 4 LTE network. At present, the deployment of 4G LTE is still uneven, and the coverage in rural areas is not perfect. For many consumers today, 4G and the future 5G will still be just the selling point of advertising marketing.
The main rod of the log-periodic antenna is two parallel thin-walled square metal tubes, which are fixedly connected by splint and installed on the bracket through horseshoe bolts. The bracket is fixed on the strut, and the steel Cable is connected to the sliding sleeve on the strut. The strut is inserted into the user support rod. The antenna vibrators are paired in pairs and fastened on the outside of the two main rods by the clamping frame. The high-frequency coaxial cable passes through the main rod. There is a sealing plug at the joint to seal and inner, and the outer conductor Connector connects the cable shielding wire and core wire with the main rod wall. The antenna can be adjusted freely in three-dimensional space. Compared with similar antennas, the length is shortened by nearly half. It is easy to set up, install, adjust, transport and low cost.
