Finally, the FCC decided to use the 280 MHz C-band spectrum (3.7GHz-4.2GHz spectrum) for the 5G network. From the launch of a series of satellites to the upgrading and testing of basic equipment, the progress is undoubtedly very slow. Most Americans can finally use the brand-new ultra-high-speed 5G mobile network in 2020.
12 In April, Xu Zhijun, the rotating chairman of Huawei, officially announced at the Huawei 18 World Analyst Conference that Huawei would launch 6G in 2030. The network speed of 6G can reach 1000Gbps, and the delay is lower than 100us (that is, 0. 1ms), which is 50 times that of 5G network. 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 change, but also qualitative improvement and huge benefits; Just as John Pierpont Morgan, a financial tycoon in the civilized world, funded Edison, forcing Tesla's funders to give up the patent right of alternating current and take this technology into the bag, Morgan became the person who lit up the United States;
Just like 2 1 century, what is the most important? Data transmission! The United States, a big technology country, certainly knows the dividends and strategic significance brought by 5G, as well as the huge profits brought by cloud computing and artificial intelligence; The lazy American government and monopoly enterprises have no clear plan to implement it. A large part of the reason is that we have not seen the profit harvest, which leads to the lack of motivation in the market and enterprises.
It's not that the American government can't light up the American Edison now. A series of measures taken by the United States simply do not recognize your Huawei technology; It's a little secretive. 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 "demolition madman" in China, and began to dismantle the 4G and 3G network equipment of Huawei and ZTE on the grounds of threatening the national defense security of the United States, even in rural areas. This not only firmly binds 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. No wonder mobile data operations in the United States are not complaining.
Two years ago, in order to seek development, Huawei wanted to cooperate with American operator Verizon to sell Huawei's latest Mate 10 mobile phone. However, under the pressure of the American 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, you still want to use my patent. There is nothing better in the world. He claimed the previous patent fee of $6,543.80 billion from Verizon, and filed a claim with AT & amp； T, like Sprint, has to wait in line to pay.
The US government is concerned about this matter, and a senator from Florida specially 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 US watch list will not be able to sue patent infringement in the United States in accordance with US law." I hope this bill is passed, and then China can also cancel the protection of all patents in the United States through the corresponding bill, so that the United States will definitely suffer.
May 2020 is the most difficult year for Huawei. BIS, 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.
There is a very interesting episode here. In order to expand 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 bombed, and the new theory was directly targeted. No matter what the proportion, as long as American technology was mixed in, it needed permission. After half a century of replication and change, the content is increasingly rich. Backed by its strong economic strength, the United States makes the long-arm jurisdiction show a trend of continuous expansion. Obviously, the United States is directly placed in the world by the laws of its specific state.
How difficult was Huawei at that time? To give a simple example, the well-known SMIC is a chip manufacturer in our country, right, but SMIC can't produce chips for it. It is really necessary to bring down Huawei, and the strength of the whole country and even national laws can be changed.
20 18, 10 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 established the White House Spectrum Strategy Working Group, requiring federal agencies to report the government's spectrum needs and study how to share spectrum with private sector users.
"Until 202 1, the wireless network in the United States has not completed this nirvana, and it still needs several years of efforts. Major mobile operators must add hundreds of thousands of new cellular base stations. Such as at & amp； The number of cellular base stations built in t 20 19 exceeds the sum of the past five years, and more base stations 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 the lovely American people. For example, the people of Chicago, who emphasize the construction of 5G, actually held a demonstration, claiming: "Fight the 5G signal and petition to stop the development of 5G." Some people even made an agreement: "When the new 5G signal comes, it will kill us all. This is not a joke! " At present, more than 30 thousand 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 cell towers on the streets of Chicago, we measured the download speed of 1.25G per second, with an average of more than 500 megabytes. Compared with the download speed of 4G signals of more than 200 megabytes per second, this speed is excellent. But sometimes it's slow, at at & amp； T's low-frequency 5G network coverage, but on the other hand, the measured AT & amp； T The average download speed of the low-band 5G system is 77.7 megabytes, and the upload speed is 18. 1 1 megabyte. The average download speed of Galaxy Note 10+ mobile phone running on T is10.7 megabytes, and the upload speed is 10.35 megabytes, which is still worse than that of 4G.
When the United States unified the 5G standard, it thought that it stood at the top of the supply chain and earned the greatest benefit with technology patents. As a result, it was robbed by Huawei. This is the root cause of Huawei's suppression.
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 the development of 6G technology to surpass China. Trump tweeted in February 2065438+2009 that "American companies that want to see 5G or even 6G technology in the United States as soon as possible must speed up their pace, otherwise they will fall behind".
The United States has launched several projects in this regard, such as the "Star Chain" project of Space Exploration Technology Company, or Amazon and space Internet technology, but they all feel like a show. There is an old saying in China since ancient times, "If you don't learn to walk, if you want to run, you will definitely fall down". On the other hand, in the process of 6G construction in China, 6G satellites have been deployed and launched in 165438+2020 10, and substantial actions have been taken to release them.
