Chapter 1696: Great times

Everyone was shocked, 8 trillion! What can this broadband do?
There are so many things to do!
You can download files freely, browse various websites, and bring out the greater value of the network. Even video calls are completely possible.
Video calls, in the past, who would have thought that when making a long-distance call, you could still see the other party's picture? This is simply high-tech, black technology.
Everyone’s faces were surprised. It seemed that this picture appeared in front of them. The internet would become a new industry!
If you want to build a website, you must develop a certain level of network technology. It's like a later generation engaged in online shopping. At the beginning, a lot of them died. Later, it was considered that a few giants finally emerged. Why? It was not because the hardware was not supported at the beginning, without a complete online payment system, complete logistics, etc., it was impossible to succeed in online shopping, but later, there were countless people paving the way before it was successful. what.
This is also the case now. When the high-speed Internet is established, and when the Internet society in Han has developed, new industries will emerge.
This will be a great era and a new growth point for technology. Of course, we must also prevent the Internet bubble.
In the West, it was also in the 1990s that the then President of the Eagle Country built an information superhighway. With this concept, the global Internet economy has developed, and the Eagle Country has also made great progress. A large number of domestic Internet giants, and now, this industry is about to rise in Han, Han will promote such projects and lead the development of the entire era.
Does the Eagle Congress suppress it? If it comes to later generations, the Eagle Country will absolutely suppress it mercilessly, and will never allow Han's technology to surpass them.
But now it’s different. Now, Eagle Nation still needs Han to maintain their strategic advantage. For Han, they are wooing, so this is definitely the best opportunity. Seize this opportunity to achieve it. Rapid development.
"A great era is coming. If you want to leave Hanxin Technology and start your own business, just like Ren Gong, I support it." Qin Guan said.
Now, the treatment of Hanxin Technology Company is quite good. After several allotments, the veterans in the company are already at the level of millionaires. This is the 1980s.
However, staying at the status quo cannot have continued development. After all, Hanxin Technology can only have one boss. If they want to develop, they will inevitably stand on their own.
Qin Guan did this for the development of the entire country and a more benign development. However, just after saying this, Qin Guan felt a pain in his waist and was already severely pounded by Lisa. Twisted it all at once.
what? You still want to encourage these people to stand on their own? You are dismantling my old lady's desk! Lisa quickly protested with Qin Guan in her brain.
Therefore, Qin Guan could only make a very strange expression, which made everyone feel very strange, and then, Ni Gong had already begun to ask his questions.
"Mr Qin, you just said that the bandwidth is divided into countless channels, then what?" Ni Gong said: "Are all these channels transmit data concurrently?"
Concurrency, that is, everyone lined up in a row, walking forward together, serial, that is, standing in a line, walking forward. Both have their own advantages. The current situation is that concurrency temporarily has advantages, so hard drives and other things are parallel.
"Yes, that's it." Qin Guan quickly turned away from the topic just now, and continued to explain: "I divided these frequencies into so many parts, mainly because I want to be more perfect. For example, the system can be adjusted according to the line conditions. The number of bits modulated on each channel in order to make full use of the line. After all, the domestic situation is different, some places have good lines, and some places have poor lines. In your professional terms, it is called signal-to-noise ratio, sub-channel The larger the signal-to-noise ratio, the more bits are modulated on the channel. If a sub-channel has a poor signal-to-noise ratio, then discard it. In short, the 8M bandwidth is theoretical, and the worst can have it. One-tenth, this rate is also quite fast."
Qin Guan’s explanation made everyone clearer. It used to be an analog signal, which is equivalent to a road on a telephone line. Now, it uses digital signals. Moreover, the road is divided 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 the most suitable machine design.
"However, in this case, the equipment at the telecommunications bureau may not be supported." Ni Gong said his last question.
For ordinary cats, analog signals are transmitted 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 on this, so many channels are separated. After entering the telecommunications bureau, I'm afraid the data is lost.
"Of course, if you want this kind of business in the class, you need to add a set of special equipment in the telecommunication bureau, which can be called a digital subscriber line access multiplexer. This thing can convert those high-frequency signals. Of course , This must increase the equipment of the telecommunications bureau. However, compared to the improvement in network performance, it is definitely worth it." Qin Guan said.
For telecommunications equipment, the most complicated thing is to lay the lines. The telephone lines are passed through different extensions, and then gradually transferred to the next, and finally reach the users. There are so many telegraph poles and thick underground cables. All of these need construction. The most complicated.
In contrast, it shouldn’t be difficult to add one or two sets of digital equipment to the telecommunications bureau’s computer room. Moreover, anyway, the telecommunications bureau needs to be continuously upgraded. These devices, and equipment for mobile communications, may be It can also communicate with each other, reducing upgrade costs more effectively.
Wiring is the most costly part.
"Okay. Qin, I have recorded all of what you said, and we will work hard in this direction. First, we will implement these functions in the big cities," said Gong Ni.
It is unrealistic to take care of remote areas. There is no way. This is the advantage of big cities. This is the case in any era. The 4G signal in rural areas is still unstable. Big cities have already transitioned to 5G, so When people go to high places, they must develop into big cities.
Qin nodded in view. Just like mobile phones, they must first be promoted in big cities. There is no problem. No one in the countryside can buy a computer. The customers are all in big cities.
