Recently, netizens have expressed their opinions on the coming of the 
G era. So today I will also talk about what this long-awaited G5 has experienced, what impact will it have on our future, and what we have seen and heard.
* Can our existing mobile phones support it when 5G arrives?
The answer is no. China's network from 2G to 4G network has been constantly improving. A few days ago, China Unicom opened a 5G base station for the first time in Guizhou branch and began to operate it officially.
, but this operation was not aimed at cities across the country, but chose 12 cities with relatively developed resources to conduct experiments, including these cities.
China Mobile: Hangzhou, Shanghai, Guangzhou, Suzhou , Wuhan conducts 5G pilot;
China Telecom: Xiong'an , Shenzhen, Shanghai, Suzhou, Chengdu, Lanzhou conducts 5G pilot;
China Unicom: Beijing, Xiong'an, Shenyang, Tianjin, Qingdao, Nanjing, Shanghai, Hangzhou, Fuzhou, Shenzhen, Zhengzhou, Chengdu, Chongqing, Wuhan, Guiyang, and Guangzhou conducts 5G pilot;
Shanghai has become the only pilot city chosen by all three operators, and two operators in seven cities, including Shenzhen, Hangzhou, Suzhou, Xiong'an, Guangzhou, Wuhan and Chengdu, pilot 5G here. How fast is
G network ? Unicom said that the peak downlink rate of the 5G network tested by a single terminal under 100MHz broadband reaches 1.8Gbps, and the average rate is stable at around 1.7Gbps. If the broadband reaches the speed limit of the 200MHz 5G network, it can reach 20Gbps, which is enough to show that the strength of the 5G network is far beyond the fastest 4G network today.
So how to use 5G? For specific discount packages and policies, we will also ask China Unicom. At the same time, most mobile phones on the market do not support 5G networks, which means that even if you buy a SIM card that supports 5G, it is useless. Only after changing to a 5G-capable phone, you can experience 5G. After another mobile phone that supports 5G, even if your SIM card only supports 4G, you can access the 5G network. In short, if you want to really use the 5G network, you can change your phone.
*5G era 4G mobile phones are not useless.
Let’s talk about ZTE chief scientist Xiangjiying--Pre5G space division multiplexing technology
ZTE chief scientist Xiangjiying
The world's first Pre5G prototype, experimental verification of 5G air-division multiplexing technology. When testing, ordinary 4G mobile phones are used. China's goal is to allow users to only replace part of the base station without changing 4G mobile phones, and they can enjoy a high-speed bandwidth comparable to 5G. This is a Chinese solution that benefits users and the country. 5G R&D engineer Xiangjiying is the designer of this Chinese solution . He and the team cooperate closely and tested for nearly two hours. , the backend data of has always been stable at about 1400 megabytes per second ,
spectrum resource usage efficiency, reaching 8 times that of 4G. The purpose of this verification is to lay a good foundation for future 5G space-division multiplexing technology. The success of laboratory test is only the first step, and the 400 mobile phones used for the test are far from being simulated. In the complex changes in the real environment, they need a larger experimental venue. As early as the "Mayday" concert on August 21, 2017, conducted a field test.
Mayday Concert
Hang 5 towers of . They will conduct the first real-life verification of 5G space-division multiplexing technology with 60,000 fans of . The concert will reach its climax. Live broadcast of live mobile phones on the Moments Test signal is very smooth and completely free of lag. The single user bandwidth in the concert test is stable at 30M per second. More demanding verification of is underway. The interference of each other's signal at high speed will lead to a rapid decline in traffic. The bandwidth of the mobile phone in is stable at 40M China's air-division multiplexing technology. The first real scene test was successfully completed. The traditional 4G signal spectrum is very limited, and the transmission speed in many dense scenes will be interfered with each other. At this time, the use of space-division multiplexing technology is particularly effective. It can increase the efficiency exponentially without the change of resources.What qualitative breakthroughs will
*5G bring to our existing Internet industry code?
Hangzhou 5G City unveiled Zhejiang Mobile first deploys 5G network Zhejiang University , Huawei , Hikvision, Alibaba , etc. More than 20 companies
enter the alliance. It is expected that 5G network will bring hundreds of millions of high-tech industries, 4G changes life, 5G changes society , large-scale concerts, live broadcasts of large events in the future, and other high-transmission network wide activities will become very useful. 5G network will improve the battery life of mobile phones and consume less power during idle time. So has many future 5G application fields, including our Internet of Vehicles, cloud computing, the Internet, smart home, smart wearables, and other areas that are highly dependent on the network will rise rapidly.
*5G network will become the era of large connection
2G era : Most of them are connections between computers and computers.
3G/4G era : Start to transform to the connection between people.
5G era : People and things, things and things will form a connection matrix, and every person and every object will become a node on the Internet, forming a large data network.
*5G network three major features
Extremely high rate (eMBB): It is expected that 5G network will be 10 times higher than 4G
Extremely large capacity (mMTC): It will meet 100 billion network connections and
polar delay (URLLC): The network delay of 5G is shortened from 50 milliseconds of 4G to 1 milliseconds of
*The current progress of domestic 5G network
China Mobile: will conduct 5G technology tests from 2017 to mid-2018, and 5G scale tests will be carried out from mid-2018 to mid-2019. From mid-2019 to mid-2020, China Mobile will conduct 5G network pre-commercial and commercial use,
China Unicom: is undergoing technical verification in 2017, and will conduct large-scale testing this year, pre-commercial use in 2019, striving to officially use in 2020.
*5G development blueprint
2020-2021 : It will focus on the development of high-definition video, 3D video, VR or AR (enhanced implementation) film and television, games, as well as intelligent transportation, robot-assisted manufacturing and remote consultation services.
2022-2023 : Focus on developing cloud office, VR or AR tourism, smart agriculture and smart cities and other businesses.
2024 : Focus on expanding VR education, smart campus, autonomous driving and remote surgery and other businesses.
my country's 5G commercial timetable has been released. The second phase of 5G network is tested in 2017, large-scale experimental networking is carried out in 2018, large-scale 5G network construction is launched in 2019, and formal commercial 5G network is officially launched as early as 2020. It is worth noting that it is based on the current technological development trend.
The fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology, foreign language abbreviation: 5G. It is also an extension after 4G and is under research.
There are currently no public specifications or official documents of any telecommunications companies or standard-setting organizations (such as 3GPP, WiMAX forum and ITU-R) that mention 5G. means that 5G will integrate a unified global standard. If the standards proposed by my country account for greater proportion in 5G network standards, my country will have greater competitive advantages and market share in the development of the information industry in the future.
* Which mobile phone brands are more likely to support 5G networks at this stage
html flagship models released in the second half of 0 may begin to support 5G networks. After all, there is an additional promotional selling point, and Huawei is the most popular on the market now. The most eye-catching thing about is that Huawei announced the Kirin 970 processor at the IFA conference a while ago, and confirmed that this processor will be equipped with Huawei Mate10.
This means that the new generation of Huawei Mate10 will bring users a "fly" experience at that time, because Yu Chengdong used a lot of adjectives when introducing the Kirin 970 processor. Among them, the most eye-catching thing of is the quasi-5G baseband , which means that Huawei Mate10 has the function of carrying 5G networks and is a real G mobile phone
In addition, Gao, a global communications giant, is also secretly using 5G smartphone . As early as April this year, according to media reports, a senior manager of Qualcomm said in an interview that the first generation of 5G smartphones will be officially launched in 2019, and Qualcomm will provide it with the most outstanding 5G components. Not only that, in October last year, Qualcomm announced the launch of the Snapdragon X505G modem at its LTE/5G summit, and said it is expected to be released in the second half of 2017 and also provided to suppliers in need to develop 5G real machines. It can be seen that Qualcomm's determination to lead the 5G mobile phone is extraordinary, and the competition in the mobile phone market next year is likely to be more intense.
Conclusion: From the above materials, we can see that 5G is not 4G, and the 4G speed will not reach 3G speed. After all, the editor believes that the times are moving forward, not backward, and China's network will be better afterwards.
You also know which mobile phone brands are closer to using 5G networks, and comments are welcome.
