finally, the FCC decided to use the 28 MHz C-band spectrum (3.7GHz-4.2GHz spectrum) for the 5G network, and the progress from the launch of a series of satellites to the transformation, upgrading and inspection of the basic equipment was undoubtedly very slow. Most Americans can finally use the brand-new ultra-high-speed 5G mobile network in 22.
on April 12th, Xu Zhijun, the rotating chairman of Huawei, officially announced at the 18th World Analyst Conference of Huawei that Huawei will launch 6G in 23, with a network speed of 1Gbps and a delay of less than 1us (that is, .1ms), which is 5 times faster than that of 5G network and only one tenth of the delay. It is far superior to 5G in peak rate, time delay, traffic density, connection density, mobility, spectrum efficiency and positioning ability.
in the era of economic globalization, the promotion and development of a science and technology brings not only quantitative changes, but also qualitative improvements and huge benefits; Just as John pierpont Morgan, a financial tycoon in the civilized world, funded Edison and forced Tesla's funders to give up the patent right of alternating current and put this technology in the bag, Morgan became the person who lit up the United States;
just like the 21st century, what is the most important? Data transmission! The United States, a big country in science and technology, certainly clearly knows the dividends and strategic significance brought by 5G, and the huge profits brought by cloud computing and artificial intelligence; The lazy American government and monopoly enterprises have no clear plans to implement them. A large part of the reason is that the profit harvest has not been seen, which has caused the market and enterprises to lack motivation.
The U.S. government is not Edison who can't light up the present United States. The series of measures taken by the United States simply don't recognize your Huawei technology. It's a bit of a cover-up. As long as I appeal to everyone not to use Huawei's 5G technology, then we will still stay in the 4G era; And began to grab the title of China as a "demolition madman" and began to dismantle Huawei and ZTE's 4G and 3G network equipment on the grounds of threatening US national defense security, even in rural areas. This not only firmly tied their hands and feet, but even today, under the leadership of the US government, the American people still don't use 5G technology very much. It is no wonder that the operation of mobile data in the United States does not complain.
two years ago, in order to seek development, Huawei wanted to sell Huawei's latest Mate 1 mobile phone with American operator Verizon. However, under the pressure of the US government, even Verizon, one of the best operators, did not dare to cooperate with it. But Huawei is not a vegetarian, since you don't cooperate with me and want to use my patent; There is nothing so good in the world. He claimed the previous patent fee of $1 billion from Verizon and at&; T, like Sprint, has to queue up to pay.
The U.S. government is concerned about this matter, and a senator from Florida deliberately submitted an amendment to the National Defense Authorization Act (NDAA). Briefly summarize the contents of this bill: "If this amendment is passed, then enterprises on the American watch list will not be able to sue for patent infringement in the United States in accordance with American law." I hope this bill is passed, then China can also cancel the protection of all patents in the United States through the corresponding bill, so the United States will definitely suffer.
May 22 is the most difficult year for Huawei. The BIS of the US Department of Commerce officially announced that it would revise the export control regulations and strictly restrict Huawei from using American technology and software to design and manufacture semiconductor chips, thus protecting US national security.
Simply put, any product that uses any parts or technologies made in the United States needs to be licensed from the United States as long as the proportion reaches 25%; Obviously, the US government is targeting Huawei.
here is a very interesting episode. In order to expand its orders, TSMC claims that all its processing technologies and OEM chips are below the 25% stipulated by the United States. As a result, the United States was blown up, and it was directly aimed at the new theory that no matter what the proportion, as long as American technology was mixed in it, it needed permission. After half a century of reproduction and change, the content is increasingly rich. Backed by its strong economic strength, the United States has made the long-arm jurisdiction show a trend of continuous expansion. Obviously, the United States is directly placed in the world by the laws of the specific state in which it is located.
how difficult was Huawei at that time? To give a very simple example, the familiar SMIC is a chip manufacturer in our country, right, but SMIC can't produce chips for it. It's really to bring down Huawei, the strength of the whole country, and even the national laws can be changed.
In October 218, US President Donald Trump signed a presidential memorandum instructing the Ministry of Commerce to formulate a long-term and comprehensive national spectrum strategy to prepare for the 5G wireless network. Trump also set up the White House spectrum strategy working group, requiring federal agencies to report the government's spectrum demand and examine how to share the spectrum with private sector users.
"Until 221, the American wireless network has not completed this nirvana, and it will still take several years of efforts. Major mobile operators must add hundreds of thousands of new cellular base stations. For example, at&; T More cellular base stations were built in 219 than in the past five years combined, and more are planned to be installed this year. It all depends on the pressure of external development, especially in China. One for the industry.
In fact, it is not only the United States itself that hinders the development of 5G, but also its lovely people. For example, the people of Chicago, who laid emphasis on the construction of 5G, actually held a parade, claiming: "Fighting against 5G signals and petitioning to stop the development of 5G" and even some people made an agreement: "The new 5G signal is coming, and it will kill us all. This is not a joke! " At present, more than 3, people have signed it.
At present, the transmission speed of the United States in the 5G network has been erratic. It has been tested by professional media before. Looking for 5G signal towers on the streets of Chicago, the download speed of 1.25G per second was measured, with an average of more than 5 megabytes. Compared with the download speed of 4G signals of more than 2 megabytes per second, this speed is excellent. But sometimes it's slow, at at&; T's low-band 5G network coverage, but on the other hand, the measured AT&; T The average download speed of the low-band 5G system is 77.7 megabits, and the upload speed is 18.11 megabits. The average download speed of Galaxy Note1+ mobile phone running on T is 1.7 megabits, and the upload speed is 1.35 megabits, which is worse than that of 4G.
When the United States unified the 5G standard, it thought that it was at the top of the supply chain and earned the most benefits with technology patents, but Huawei took the lead. This is the fundamental reason why Huawei was suppressed.
The United States is still completely blocking Huawei and its 5G technology. At the same time, Washington has begun to focus on "leapfrog development", hoping to focus on developing 6G technology to surpass China. Trump once tweeted in February 219 that "American companies that want to see 5G or even 6G technology in the United States as soon as possible must speed up their efforts, otherwise they will fall behind."
The United States has introduced several projects, such as SpaceX, Star Chain, Amazon and space Internet technology, but they all feel like a show. There is an old saying in China since ancient times that "if you don't learn to walk, you want to run, but you will surely fall down". On the other hand, in November 22, China began to deploy 6G satellites and made substantial actions and releases.
