"What are you humble? I praise you. Su Dingyu looked at Jiang Xinwei playfully and said with a smile, "Hehe, this is what Guo Qian and I heard with our own ears, you said at the time that you would give college students some money to buy Christmas gifts for their lovers." I also used this excuse to go to my classmate and ask him to help organize a group of students. …… , hehe, you have burned the fire now, and you won't admit it?"

Jiang Xinwei smiled bitterly: "I can explain myself by thinking of the beginning but not the end." …… , Okay, since things have been almost done here, Guo Qian and I will go back to the company tomorrow, and you will be in charge of the affairs here. ”

Su Dingyu glanced at Jiang Xinwei and said, "Okay, you all go." …… Although I can't be sure that we will achieve the same surprising results as last year's Canton Fair, I think the results will not be bad. ”

On the third day of the exhibition, Jiang Xinwei returned to Zi'an City with Guo Qian.

On the one hand, he continued to guide Guo Qian and Zhu Jianhua in compiling the maintenance procedures and technical standards for the wireless paging and transmitting system designated by the Ministry of Posts and Telecommunications, and on the other hand, he began to prepare for the design of program-controlled switches.

This is a decision made by Jiang Xinwei Tong Guò after careful consideration. People who are slightly familiar with the telecommunications room know the three major parts of the computer room: switch equipment, transmission equipment, and power supply equipment.

In the current state of technology, the technical content of the switch is the highest among these three types of equipment, and there are many manufacturers in the production of transmission equipment and power supply equipment in China, and the demand for new technologies and new products is not urgent.

Although the transmission equipment can only develop and produce PDH optical transmission in China, the transmission rate is not high for the time being, and the maximum speed of the optical transceiver currently put into commercial use is only 140M, but this rate and PDH mode can fully bear the current communication volume between China's switches and switches. A single fiber optic cable can allow nearly 2,000 people to make phone calls at the same time. Moreover, several manufacturers have developed a multi-system 140m optical transceiver, which can accommodate six or seven systems at the same time in one cabinet, and can also realize the 1+n multi-master and one-backup security communication mode.

As for the power supply, although there is no domestic switching power supply, the DC power supply used in many communications is still obtained by the old-fashioned transformer bridge rectification. However, such equipment can still bear the power demand of switches and transmission equipment. It is nothing more than low rectification efficiency, large equipment footprint, and a lot of wasted electricity, but it can still be maintained, and there is not much dependence on foreign equipment, which is a situation that can be bought or not.

In addition, the current domestic foreign exchange is tight, and telecommunications companies are not used to buying everything abroad, and they are using domestic equipment as much as possible. Therefore, Jiang Xinwei is not worried about how much market transmission equipment and power supply equipment will give to foreign manufacturers, so he naturally has no need to bother with these two types of products.

However, the switch is different, it is a product that urgently needs to be produced in-house. Because of the high technical content of switches, the current domestic manual switches, stepper switches and vertical and horizontal systems are all products that must be eliminated immediately. It is simply not suitable for the needs of communication now. Just think about how bad the situation should be if a township can only allow a few dozen telephones to be installed, and how bad the situation should be for a township with a population of tens of thousands to only allow one or two people to make phone calls from outside, how great will the restrictions on economic development be, and how much trouble will it cause to people's lives?

To change this, it is necessary to install a program-controlled switch.

However, our program-controlled switch technology is too backward, and the domestic switch with more than 10,000 doors was not developed until November this year, that is, a month ago, and it may not be put into trial operation until next year. And the switch technology they developed is not yet mature. The products produced can only be tested, that is, tried to be used.

In fact, even if the technology is mature, they do not have the ability to produce switches on a large scale. Mass production is simply not possible. Forced by the shape and customer demand, domestic communication companies can only purchase the best way to replace the machine to solve the contradiction of insufficient domestic communication.

Therefore, Jiang Xinwei, who is determined to rise in the telecommunications industry, has focused his attention on the switch and the user-type switch after the development of the pager has come to an end.

The reason why the development of switches is focused on user switches (i.e., small switches) is that he has other ideas: he does not have the energy and technical strength to design and develop large switches.

This time, he is no longer ready to go it alone. Instead, it organized and commanded a group of scientific research personnel to jointly tackle key problems, and cultivated a group of high-quality scientific research personnel while inventing the switchboard. Let them take over their courage and let them accumulate high-tech technologies related to digital communication. In the future, they will also develop large switches.

This time, he put himself in the position of organizer, commander, and guide, and no longer did everything himself, but at most he gave guidance and help when they encountered great resistance and great difficulties.

The reason why he dared to do this was because he remembered that in his previous life, China's world-famous private communications company also organized dozens of technicians to develop switches by themselves at this time.

In the past, they were acting as an agent for the import of HAX series program-controlled switches, and at the same time assembling their own BH01 switches with foreign components, but whether they were imported or assembled by themselves, they could not meet the needs of domestic switches at all. In the face of the influx of orders and the urgent need for switches from all over the world, the people of this company saw the business opportunity and resolutely organized more than a dozen people to start the development of switches with their own intellectual property rights.

They not only earned a lot of money for this, but also cultivated a large number of high-quality technical teams, which laid a solid foundation for their later development.

Jiang Xinwei's current conditions are much better than those of the private enterprise at that time, he now not only has smooth procurement channels for foreign electronic components, not only has the strong support of the relevant state departments, but also has advantages over the private enterprise in terms of talent and policy, and more importantly, Jiang Xinwei now has abundant funds in hand, and can invest tenfold, hundredfold or even thousands of times more scientific research funds than that private enterprise.

What's more, he is still a traverser, with a golden finger that private enterprises do not have, knows all the key points of program-controlled switch technology, can point out the difficulties and problems encountered by scientific researchers in production at any time, and can even say some key parameters and optimal parameters lightly, without them having to say more energy to find and explore.

Moreover, Jiang Xinwei can also easily judge whether their scientific research path is correct, and in the process of development, he can see at a glance whether they have gone astray and whether they have taken a shortcut.

As long as he wants, he can guide them step by step.

Although he can't guarantee that they will be able to complete the design and production of a certain functional board, he can guarantee that their development will be successful, not a failure.

If there are such good conditions and so many talents, it is not possible to achieve more and faster success than any private enterprise in his previous life, Jiang Xinwei should really buy a rope and hang himself.

In addition to cultivating a large number of high-tech talents with modern digital communication technology, Jiang Xinwei also has an idea that he has to prepare for the outbreak of mobile communications in the next few years......

Of course, he also has to prepare for the development and production of mobile communication switches, mobile communication base station equipment.

As a truly modern communication enterprise, it is inseparable from mobile communications. Jiang Xinwei, who is well aware of the development of telecommunications technology, knows that the telephones and pagers he currently produces are either marginalized or eliminated, and will be the world of mobile communications and Internet communications in the future.

The main reason why he is now developing and producing two products, which obviously have little future, is to accumulate funds and reserve talents. If you don't have money or talent at hand, even if you are a traverser, you can't make a difference on your mobile phone right away, and you can't suddenly become the darling of the Internet, and you will become a trendsetter admired by others, and it is even difficult to catch up with them.

In fact, now large foreign communication enterprises and scientific research units have made progress in the field of mobile communications that the Chinese people do not know, China's analog mobile communications have not yet begun to build, the first period has more than five years, but foreign countries already have mature digital mobile communication technology, European GS-M base stations and mobile phones have been in commercial use.

As for the Internet, there are only a few prescient people in China who are using telephones and modems to connect to the root server of the Internet in the United States to see the novelty, the Internet is still only a name that is not clear in the minds of the Chinese people, but the mature Internet technology has been widely used in the United States and Europe, and each university has almost established its own local area network, and ordinary students can use the microcomputer and the local area network to connect to the Internet running a stable dìng to study.

If Jiang Xinwei had entered mobile communications and the Internet from the beginning, what he could do would have been to write a paper and apply for a few patents with the knowledge he had brought from the time. Moreover, he is not sure what level some technologies have reached abroad, and he does not know whether he can come up with some relatively old technologies and some relatively basic technologies, because once he comes up with these technologies, it is likely to overlap with other people's technologies or even constitute infringement.

In order to avoid these situations, the safest thing is to come up with the relatively new technology and new methods of communication equipment that he has memorized in his mind, or even travel back to the previous years. However, although this can avoid infringement, it will inevitably bring some problems......
