Super Dimension Technology Era

At this time, whether it is in the snowy areas of the Qinghai-Tibet Plateau, the Hulunbuir Prairie outside the Great Wall, or the windy sand in the Tarim Basin.

As long as there is a communication base station, you can directly log into Nanke Dream World through the brainwave glasses.

In the twists and turns of the Yunnan-Guizhou Plateau, under the blue sea and blue sky of the South China Sea, in the bustling cities on both sides of the Yangtze River.

Countless testers holding terahertz mobile phones are making calls, sending text messages, and surfing the Internet.

Huang Tianci, who was in Baise City, took his mobile phone, selected a movie website on Citizen Home, and clicked to download the just-released science fiction movie "Mechanical Planet."

After paying, he clicked on the movie and it appeared on his phone. The download time was almost imperceptible, and multiple web pages were opened at the same time. The Internet speed was still very fast.

According to traffic monitoring, the download speed has almost reached 300G per second, and the upload speed is almost the same.

The 5G communication currently under development can theoretically reach 10G per second, but in fact it cannot reach this value. In Huawei's communication laboratory, it can achieve 400M per second.

As for the 4G communication currently in use, it is generally below 10M per second, while the wired optical fiber communication is about 1000M per second.

It can be seen that terahertz communication is more powerful than optical fiber communication, 4G, and 5G, but terahertz has not yet reached its limit. Its upper limit of transmission speed is about 1T, or 1024G per second.

In fact, there is a huge problem in terahertz communication, that is, serious road damage, and the traditional communication distance does not exceed 10 meters.

However, Huang Mingzhe solved this problem. He found a special frequency band in the terahertz frequency band, and then used power and encoders to stimulate a characteristic of this frequency band.

That is the characteristic of the ionospheric amplifier. This special frequency terahertz wave will be greatly amplified after passing through the ionosphere of the atmosphere, and can penetrate most air components, effectively reducing path loss problems.

In this case, it not only avoids the embarrassment of traditional communication satellites, which are easily disturbed by atmospheric movements; it is also different from the helplessness of traditional wireless communication base stations, which must ensure communication quality by deploying a large number of base stations.

In areas without base stations, terahertz communication can still provide communication quality of about 30G per second; in areas covered by base stations, it can reach the fastest communication quality of 360G per second.

For example, Huang Tianci's current base station in Gaolingzhai can cover a radius of about 3 kilometers, but considering the obstruction of the mountain, it is estimated that it can only cover about half.

However, this problem is not unsolvable. Relay stations can be built in various areas. The terahertz communication jointly developed by Sisishe and Huawei uses two modes in parallel.

That is, communication satellites provide large-scale communications, while ground base stations provide high-quality communications in small areas, forming coverage without blind spots.

In addition to large base stations in mountainous areas like Gaolingzhai, micro base stations are still being tested in the eastern urban areas of Guan City, Huizhou City, and Shanmei City.

In an ordinary office building in Shanmei City, more than a dozen testers are testing micro base stations. The micro base stations are about the same size as our common routers. After being plugged in, they can serve a radius of 50 to 20 meters.

Micro base stations can be directly connected to computers and mobile phones, and can also be connected in series to large base stations to achieve full coverage in cities.

"So fast!" The tester walked around the entire office building with a terahertz mobile phone, while another tester continued to record data.

These data need to be fed back. As an improvement to the terahertz communication system, there are definitely some problems as a first-generation product. Although it is perfect in the laboratory, in actual applications, the situation is much more complicated than in the laboratory.

"I found a problem. There is a certain amount of interference when close to electrical appliances. Especially when it is around the original 4G base station, the interference is very obvious."

"In addition, if it is a reinforced concrete wall, the blocking effect is stronger than that of a plywood wall. In underground parking lots and tunnels, satellite signals are almost impossible to receive, and we can only rely on base stations."

"Another problem, insufficient memory on the phone, can also become a big problem."

One piece of usage feedback was sent back to the joint operations center in Haicheng County. Chen Wenna and Yu Chengdong, Wang Kedao from the Tower Company, and Fan Xinhang from Star Communications were discussing these matters.

The Tower Company was originally a joint venture between China Mobile, China Unicom and China Telecom. However, the situation is different now. The Citizen Trust injected capital into the Tower Company and held 27.6% of its shares, becoming the largest shareholder.

After all, Think Society and Citizen Trust Society are the initiators of terahertz communications, and Star Communications has become the fourth domestic communications service operator and also holds 30 terahertz communications satellites.

Even without communication base stations, Star Communications Company can still develop and grow. However, the three giants of China Telecom, China Mobile, and China Unicom can only enter this market by default.

Because they also need terahertz communications, this is the background for the Citizen Trust's successful investment in the tower company, and both parties get what they need.

"Mr. Yu, your Huawei mobile phones need to further adapt to terahertz communications!" Chen Wenna has already seen the problem of insufficient memory in mobile phones.

Yu Chengdong had no choice but to say: "Hisilicon launched 12nm 64G memory last month, but it seems to be insufficient."

He did not expect that the world would change so quickly. In the past two years, everyone was talking about 5G communications, but now terahertz communications (6G) have been introduced, causing the level of some hardware to not keep up with the communication system.

To meet the needs of terahertz communication systems, it is estimated that T-level memory will be initially sufficient.

"I heard that SMIC has developed 128G memory. Mr. Yu can consider it." Chen Wenna reminded.

"Haha, I will consider it." Yu Chengdong replied with a dry smile. Of course he knew that SMIC has successfully developed 128G memory. The problem is that this thing is very expensive, three times the price of 64G memory.

Obviously, he doesn't want to buy SMIC's chips. In addition, Huawei also has its own chip company HiSilicon, so the order must be given to his own son.

But in this situation, after weighing the pros and cons, he decided to buy a batch to use on high-end mobile phones and make do with ordinary mobile phones for the time being.

The test lasted three days. The four companies improved and adjusted the terahertz communication system based on the problems discovered during the test.

Testing and adjustment work will be carried out alternately, and they are striving to improve the terahertz communication system to perfection.

While each company is improving its own part, it is also communicating about problems in the process.

After all, the communication field involves communication base station equipment manufacturers, communication equipment builders, communication service operators, communication terminal manufacturers, and Internet companies.

All aspects must be considered. Optimizing alone will most likely cause problems in other parts. Regular communication is essential.

The scale and scope of the test are also expanding, and rumors have begun to appear on the Internet, but no official announcement has been made by each company.

The three giants of China Telecom, China Mobile, and China Unicom have not been disturbed by the outside world. They are now meeting to discuss how to follow up on terahertz communications.

For example, leasing communication satellite services from Star Communications, modifying the original communication protocol, traffic charging issues, old users being unable to use terahertz communication, etc.

These things are enough to give them a headache for a while.
