Chapter 839 5G Pre-Commercial Use

While the good news of 5G broke out in China, there were also many 5G-related things in Europe.

Deutsche Telekom was the first to announce the construction of Europe's first 5G pre-commercial network in the center of Berlin, successfully realizing the commercial application of 5G, and the first demonstration made in Germany was 5G+ drones, which realized drones through 5G communication. remote control, the on-site completion is very high.

The first 5G pre-commercial network built in Berlin this time was jointly established by Deutsche Telekom, Vodafone, Dafeng Group, Huawei and ZTE.

Not long after the news from Germany came out, Italy seemed to be a bit unwilling to lag behind. It immediately announced the start of the 5G pre-commercial network in Italy, and demonstrated the real-scene experience of 5G+ virtual reality on the spot. The commercial network is built by two major Italian operators, Wind Tre and Open Fiber, as well as China's Dafeng Group, Huawei and ZTE.

The 5G pre-commercial network launched by Germany and Italy almost at the same time symbolizes the opening of 5G commercial use in the European market, making the world aware of the key role played by the three Chinese companies in the development of 5G in Europe, and at the same time confusing everyone.

The first confusion is why we have to cooperate with the three companies. The answer is that the three Chinese companies have different advantages. Dafeng Group’s advantage is chips, Huawei’s advantage is equipment, and ZTE’s advantage is network construction.

The three companies have combined their respective advantages and are invincible

The second confusion is also the most frequently asked, what is the meaning of pre-commercial use, what is the difference from commercial use, and will it affect the real commercial use in the later stage.

And someone stood up to help the three Chinese companies answer this question. This person is Philip Johnson, CEO of British Telecom.

Philip explained in front of the camera, "The so-called pre-commercial use means to start building a commercial environment in advance on the premise that the technology is mature enough and the judgment of standards is accurate enough, which will help us to be one step faster in the entire 5G development process." .

Therefore, in order to achieve pre-commercial use, there are two conditions. One is sufficient technical confidence and absolute control over the right to formulate future standards, and the other is comprehensive forward-looking, which can ensure the stability of existing investments and the compatibility of future standards. sex.

Now the most powerful to achieve these two points is the three giants of Huaxia Communications composed of Dafeng Group, Huawei and ZTE.

Therefore, the 5G pre-commercial construction of these three companies is basically consistent with the released version of 3GPP in terms of standards and core indicators of the protocol. For example, in terms of frame structure, they basically adopt the same frame structure as 3GPP.

In terms of standards not defined by 3GPP, the three Chinese giants will design based on the unified viewpoint discussed among multiple manufacturers and partners. Therefore, the pre-commercial system will have a very high degree of compliance with the final standard of 3GPP for official commercial use in the future. Once the future standard is frozen, the equipment can be directly upgraded to the 3GPP standard. "

The CEO of BT is willing to stand up and explain. On the one hand, it is because Huawei has a deep relationship with BT in the past. In October 2012, Huawei helped BT launch the first 4G commercial network. First LTE-A network. For a long time, Huawei has continued to make outstanding contributions to the construction of the UK mobile network, which cannot be replaced by any other communication company.

On the other hand, it is because the UK has also launched 5G pre-commercial use. Seeing that Germany and Italy are starting to show off, the UK will naturally not sit still.

And this time the UK still has a good card in hand. Huawei has put the verification of the key features of 5G commercial use, uplink and downlink decoupling, in the UK.

Uplink and downlink decoupling is a very important technology, because 3.5GHz has abundant spectrum resources, and it is destined to become the main capacity and coverage layer of 5G. The downlink coverage and capacity indicators under the conditions are very ideal, but the improvement of the uplink indicators has encountered a bottleneck.

In order to prevent operators from building too many new sites in the 5G era, they must overcome the uplink bottleneck. Huawei’s experiment in the UK successfully broke the limitation that the uplink reception and downlink transmission of the traditional communication system must be bound to one frequency band, and greatly improved edge user experience. Brings a revolutionary full-spectrum network construction mode

According to the results of the test, after using Huawei's uplink and downlink decoupling technology, the uplink coverage is increased by 11dB9, the coverage radius is increased by 73%, and the base station coverage area can be increased by 3 times.

The active performance of the three European countries has shown the world their leadership in 5G commercial use and laid a good foundation for future 5G battles.

At the same time, it also helped the three giants of Huaxia Communications to become famous for a while. Almost all countries planning to build 5G commercial networks knew who to go to now. The three European countries helped to advertise once, and it was a free advertisement.

But the more this happened, the more uneasy some people became.

In just over two months, the matter of cars and 5G has caused some Americans to have a sense of crisis.

In response to the 5G issue, relevant professionals in the United States directly wrote an article saying: China is controlling the 5G era.

The author said, "China has achieved the leading position in 5G pre-commercial use, and in addition to the United Kingdom, Germany and Italy, there are more than a dozen countries in Europe that will launch 5G pre-commercial use this year, and all of them are built by the three giants of Huaxia Communications. At the same time, many After seeing the performance of the three European countries, a country found the three giants of Huaxia Communications and invited them to participate in 5G construction so as not to fall behind.

According to this trend, when the 5G commercial era really comes in the future, it will basically be dominated by China, leaving little chance for the United States to overtake.

Therefore, what America should do at this time is to cooperate. Intel and Qualcomm should seize the time to cooperate with Ericsson and Nokia, and use the cooperation of Omi companies to counter the crazy development speed of the three Chinese giants. most efficient way. "

Faced with suggestions from market participants, Intel and Qualcomm also showed positive cooperation intentions. While public opinion was fermenting, Krzanick first showed Intel's various breakthroughs in 5G, expressing that Intel has not fallen behind in 5G At the same time, he said that Intel intends to cooperate with Ericsson and Nokia to deepen cooperation, and also posted a photo of himself having dinner with Ericsson CEO.

Enterprises are willing to respond, so that more stakeholders still feel more at ease, although there must be pressure.

But when the market reacted as it should, the government also took action.

In mid-April, a neat row of messages suddenly appeared under Meng Qian's Fengxin.

"Please investigate the Gale Group."

Every day when Meng Qian opens Fengxin, he will see a bunch of people Aite himself and write such a sentence, but the netizens are not malicious. The reason for this kind of reaction is because the recent "In the Name of the People" hit the air, and netizens said that the wind As soon as the factory heard it, it knew that it was under the Dafeng Group, and the Dafeng Group was responsible for the workers of the Dafeng Factory.

This suddenly became a very popular meme in April in China.

However, what made this even more popular was that when everyone was teasing Dafeng Group, news suddenly came out from the US side, making this meme a reality.

The United States claims that the products of Dafeng Group have serious security loopholes and requires investigation of Dafeng Group.

Before the final investigation results come out, the United States will adopt an entry policy on the chips and software of the Dafeng Group.

Dafeng Group was suddenly stopped outside the country of America.

This incident once again caused a lot of public turmoil, including in the United States.

Because of this matter, it seems to be the most direct approach. The root cause of all this is that the Dafeng Group is too powerful, so it will be over if the Dafeng Group is directly involved, and the core problem will be solved.

But this approach always seems to be a problem.

From the auto industry's pressure on allies and their refusal to cooperate, to the brutal and unreasonable suppression of the 5G industry, for those sensitive capitalists and politicians, they have already felt that something is wrong, but they can't tell for a while.
