Although her tone sounded a little stiff, Jiang Xinwei knew that she was pretending. She didn't want to show her weak side in front of him, and wanted to continue to maintain her cold and arrogant image.

But he didn't say anything, but immediately ended the call and said, "Goodbye!"

As soon as the words fell, I heard a snapping sound from inside, and hung up.

Looking at the microphone, Jiang Xinwei smiled.

With Su Dingyu and Director Wei busy signing contracts and shooting advertisements, Jiang Xinwei only needs to wait until the sample is filmed to review, and he begins to officially get busy with an important matter: the wireless paging transmitter system!

Why did Jiang Xinwei choose the wireless paging and transmitting system? It was because he knew that the pager -- also known as the BP machine -- would sweep across the country like a hurricane in the future. In a few years, everyone will be proud to own a BP machine, and eight years later, the number of online users will be as high as more than 68 million!

It also means that there are more than 6,000 BP machines in use in the country, and you must know that the common life of BP machines is only about two years, and how many BP machines should be damaged and eliminated? The total number is at least more than 200 million!

If you just look at the number of BP machines, it may only make people think that the BP machine market is a real gold mine, but it is not enough to make people stunned, because the number of mobile phones in the 21st century is even larger, almost everyone has one, even those who pick up garbage on the street. But if you look at the price of BP machines in this era, you will definitely be tempted to jump:

At this time, the BP machine was as high as more than 2,000 yuan, but the wages of workers at that time were less than 100 yuan or just over 100 yuan, which means that people are willing to spend a year or even two years of income to buy a small BP machine.

At this time, the second housing reform has just begun, that is, the housing price in the city center is less than 300 yuan per square meter, and a BP machine can be worth seven to eight square meters of housing area!

How many square meters of housing can an average smartphone in the 21st century reach?

The number of BP machines used is staggering, as is the number of transmitting systems that naturally emit their signals, because each system can only cover a certain area and send information to the BP machines in that area. The price of BP machine is high and the profit is high, and the unit price of wireless paging and transmission system is higher and the profit is more amazing.

The cost of a wireless paging and transmitting system is about 40,000 yuan, but the selling price is as high as more than 200,000 yuan, or even nearly 300,000 yuan, and its profit is as high as 400% on average!

And this profit is only in the early stage, it is obtained when it is installed and opened, and it does not include the profit from the sale of BP machines after the wireless paging and transmission system is opened, as well as the profit from the upgrade of the operating system, application software and management software, and does not include the profit from the development of new functions of the system in the future.

In particular, the management software is being upgraded almost every year, because with the operation of these wireless paging stations more and more businesses, the competition between merchants is becoming more and more fierce, under the premise that the signal quality can not carry out too much competition, they are fighting on the quality of service, and they continue to hope that manufacturers will provide more and better service software.

In order to be the first to get good service software, these merchants are very happy to pay money, but I am afraid that you don't have it.

As for the launch of stock machines, weather forecast services, traffic information services or something, it is another additional new function, which can also provide considerable income for wireless paging and transmitting system manufacturers.

It can be said that as long as you have the ability to produce wireless paging transmission systems, as long as you know the direction of wireless paging in the next few years, you are equivalent to owning a bank, and it is a bank that others are eager to send money to you.

Because you are at the very top of the food chain, the animals at the bottom of the food chain are your food.

The wireless paging transmission system is indeed a high-tech product with high technical content for others, but it is not so profound for Jiang Xinwei who has crossed over, not to mention that it is compared with the carrier frequency of the digital mobile base station, and it is not a grade at all compared with the transmission unit of the analog mobile base station, this thing is too simple.

Who else is more familiar with the future direction of development without paging? He can make money over and over again from Chinese consumers, and even do better than them, just like those foreign manufacturers in his predecessors, because he can get out of a straight road without groping. He can snatch the money that originally belonged to foreign manufacturers into his own pocket, and he can also export this system to rob foreign consumers of their money and loot the pockets of foreigners again and again!

BP machine is not only prosperous in mainland China, but also in Japan, Baodao, Hong Kong and Macao, Indonesia, Singapore and other places, and has a huge market share in these regions. Jiang Xinwei has enough confidence to launch a wireless paging system with better performance and quality than other enterprises in the world, and he believes that his operating system, management system and other software and system hardware are more suitable for the needs of paging enterprises, which is enough to compete with European and American companies in the field of paging and paging in the market.

Of course, the development of a wireless paging and transmission system is not without difficulties at all, and it does not mean that Jiang Xinwei can assemble a set of transmission systems in a few clicks. If this is the case, he will not let Shengli Electronics No. 2 Factory use the assembly of telephones to transition this time, and will not use the assembly of telephones to earn a little money to stabilize the workers, just directly produce and launch the wireless paging transmission system?

If it is in the 21st century, he can indeed complete the development of this system lightly, because the electronic components required by the system, including chips, are readily available in the electronic market, and it does not cost much money to purchase all the chips, electronic components, and related accessories from the market, and their performance can meet and exceed the needs of the system, such as single-chip microcomputer, such as memory, they can be called cheap and high-quality for wireless paging and transmission systems, and they can be used after assembly.

But now it is not possible, especially in China, it is difficult to buy the corresponding processor, digital-to-analog conversion chip, it is difficult to buy power amplifier circuits with stable performance, and even some accessories are difficult to match.

However, no matter how great the difficulty is, it is difficult for Jiang Xinwei to be difficult, precisely because he is familiar with the principle of the transmission system, knows how to replace it with the current electronic components, and knows how to use multiple electronic components to combine to achieve a certain function, the only thing he needs is time, he needs time to investigate those electronic components in the market, which integrated circuits can be used for his own use; he needs time to modify the design, so that his design is not so lofty, but to adapt to the current hardware environment; it takes time to try one by one, and collect the number of tests again and again to obtain the most ideal technical parameters……

But he believes that as long as he gives himself time, he can definitely design a wireless paging transmitter system that is no less than that of a foreign company.

And he had time to develop it, because according to the history of his previous life, the pager was booming three years later, along with the program-controlled telephone. The paging system and the program-controlled switch promote each other, which leads to the rapid development of telecommunications in China:

If there are not enough program-controlled telephones on the streets, it will be difficult for people to send out paging signals, and it will be difficult for pager owners to return calls. Similarly, without pagers, there are far fewer callers, fewer calls, and less desire to install telephones.

Three years, that's enough!

He believes that it will take two to three years to complete the technology development, production arrangement, and sales layout...... , and he won't stupidly wait for two or three years, but push it out as quickly as he can. If the people can't catch fire for the time being, they will first occupy the departments that need paging systems in advance, such as public security, railways, and electric power.

The wireless transmission system developed by Jiang Xinwei uses the FLEX protocol of Motorola of the United States, which occupies 160 megabytes of wireless frequency.
