Chapter 1696

Everyone was stunned, 8 trillion! What can such broadband do?

There's too much to do!

You can download files and browse various websites freely, which can play a greater value of the network. Even video calls are completely possible.

Video call ah, in the past, who could have thought that when you called from a distance, you could still see each other's picture? This is high technology, black technology.

Everyone's face is surprised. There seems to be such a picture in front of them. The network will become an emerging industry!

If you want to build a website, you must develop network technology to a certain extent. It's like online shopping in future generations. At the beginning, a large area died. Later, it can be regarded as the rise of several giants. Why? It's not because the hardware didn't support at the beginning, there was no perfect online payment system, perfect logistics, etc. it was impossible to succeed in online shopping, but later, there were countless people paving the way in front, so there was subsequent success.

Now it is the same. When the high-speed Internet is established and the network society in Han country has developed, new industries will rise.

This will be a great era and a new technological growth point. Of course, we must prevent the damn Internet bubble.

In the west, but also in the 1990s, the then president of Eagle country developed the information superhighway. With the help of this concept, the global Internet economy has developed, Eagle country has also made great development, and a large number of Internet giants have been born in China. Now, this industry will rise in Han country, and Han country will promote such projects, Will lead the development of the whole era.

Will the eagle Congress suppress it? If it comes to later generations, the eagle country will absolutely ruthlessly suppress it, and it will never allow the science and technology of the Han country to surpass them.

But now it's different. Now, Eagle country still needs Han country to maintain its strategic advantage. For Han country, they are courting, so this is definitely the best opportunity. Seize this opportunity to achieve rapid development.

"A great era is coming. If you want to leave Hanxin technology company and start your own business, it's like being a worker. I support it," Qin Guan said.

Now, the treatment of Hanxin technology company is quite good. After several allotments, the elders of the company are millionaires. This is the 1980s.

However, there can be no continuous development if they have been content with the status quo. After all, there can only be one boss of Hanxin technology company. If they want to develop, they will be independent.

Qin Guan did this for the sake of the development of the whole country and more benign development. However, just after saying this, Qin Guan felt a pain in his waist and had been severely twisted by Lisa.

what? You still want to encourage these people to go their own way? You're dismantling my platform! Lisa was also protesting quickly with Qin Guan in her brain.

Therefore, Qin Guan could only make a very strange expression, which made everyone feel very strange. Then Ni Gong began to ask his questions.

"President Qin, you just said that those bandwidths are divided into countless channels, and then?" Ni Gong said: "are all data transmitted concurrently on these channels?"

Concurrency, that is, everyone lined up and walked forward together horizontally, serial, that is, lined up and walked forward vertically. The two have their own advantages. The current situation is that concurrency has an advantage temporarily, so hard disks are parallel ports.

"Yes, that's it." Qin Guan quickly turned off the topic and continued to explain: "I divide these frequencies into so many parts, mainly to improve them. For example, the system can adjust the number of bits modulated on each channel according to the situation of the line, so as to make full use of the line. After all, the domestic situation is different. Some local lines are good and some local lines are poor. In your professional words, it is called signal-to-noise ratio, the signal-to-noise ratio of subchannels The larger the ratio, the more bits are modulated on the channel. If the signal-to-noise ratio of a subchannel is very poor, it will be discarded. In short, the bandwidth of 8 megabytes is theoretical, and the worst can be one tenth of it, which is also very fast. "

Qin Guan's explanation makes everyone more clear. In the past, it was analog signal, which is equivalent to a road on the telephone line. Now, it takes digital signal. Moreover, it also divides this road into 256 roads, and the speed increases. That's for sure.

As for why it is 256, of course, it comes from binary, which is most suitable for the design of the machine.

"However, in this case, I'm afraid the equipment at the Telecommunications Bureau doesn't support it." Ni Gong said the last question.

Ordinary cats transmit analog signals on the line. The program-controlled switching equipment of the telecommunications bureau does not need to be changed, but now, if digital technology is used to separate so many channels, I'm afraid the data will be lost after entering the Telecommunications Bureau.

"Of course, if you want this kind of business in the class, you need to add a set of special instruments in the Telecommunications Bureau, which can be called digital subscriber line access multiplexer. This thing can convert those high-frequency signals. Of course, it must increase the equipment of the Telecommunications Bureau. However, compared with the improvement in network performance, it is definitely worth it," Qin Guan said.

For telecommunication equipment, the most complex thing is to lay lines, gradually transfer the telephone lines through different extensions, and finally reach the users. After walking through so many electric poles and thick underground cables, all these need construction, which are the most complex.

In contrast, it should not be difficult to add one or two sets of digital equipment in the computer room of the Telecommunications Bureau. Moreover, the Telecommunications Bureau needs to constantly upgrade anyway. These equipment and mobile communication equipment may be able to communicate with each other, so as to reduce the upgrade cost more effectively.

Cabling is the most expensive part.

"All right. Mr. Qin, I have recorded what you said. We will work hard in this direction next. First, we will realize these functions in big cities," said Ni Gong.

It's unrealistic to take care of remote areas. There's no way. This is the advantage of big cities. It's the same in any era. The 4G signal in rural areas is not stable, and big cities have transitioned to 5g. Therefore, people should develop to big cities when they go up.

Qin Guan nodded. Just like mobile phones, they must first be promoted in big cities. There is no problem. In rural areas, no one can buy computers. Customers are inside big cities.
