If it is the 21st century, it is obviously impossible for him to do this, and before and after the product is put into production, he must buy the relevant patents from Motorola, and pay the relevant patent fees before it can be put into production.

However, it is now the 90s, China has not yet joined the WTO, there is no need to abide by the foreign patent use law, and now the Western countries have imposed a comprehensive embargo on our country, and there is no need to pay attention to patents or anything: you have embargoed against us, we produce and sell in China, why should we pay attention to you?

It can be said that now is the best period for misusing foreign patents, and it is also the best period for copycats, as long as you can produce excellent products, not to mention that no one will hold you accountable for misusing foreigners, but will get the private support of the relevant state departments, if you can develop a good product that is not available in China, a domestic first laurel will also fall on your head, so beautiful that your snot is bubbling, hehe.

Of course, if the product is exported, it will need to be negotiated for patents. Jiang Xinwei also thought of a countermeasure to this, the big deal is to apply for a few patents in telecommunications equipment before the product is exported, and even plagiarize the patents of several Motorola companies that he knew in his previous life and apply to the US Patent Office.

Besides, as long as you find out and occupy the vast paging market in China, you will have enough bargaining chips to negotiate with others, and if necessary, you can take a part of the market to share with the other party and give them the opportunity to compete.

Jiang Xinwei thought silently in his heart: "Now I still have no personnel, no funds, no brand, no market, there is no need to think so much, I can't think about so much, I can't afford to buy a small patent, what can I talk about buying international patents? At present, I can only take one step at a time, and making money is the king." ”

The composition of the paging wireless transmission system is very simple, mainly including information processing unit, digital-to-analog conversion and transmission unit, radio frequency circuit and antenna feeder system. The information processing unit comprises a user call collection system, a call queuing system, an information coding system, and a management assessment system.

The system may sound very complicated, but it is actually not that complicated, such as the user call collection system, the main circuit is a set of audio number receiving chips, a set of memory and some auxiliary circuits:

When a distant user picks up the telephone and presses the code of the BP operator, such as 127, 126, 191, or simply a specific phone number, the telecom switch will forward the user's call, and you can use the audio number receiving chip to complete the translation of the call number, just save these numbers temporarily, and wait for the call queuing system to pick up.

As for the manual paging station, it is simpler, the paging lady will answer the call of the other party manually, will ask the other party which BP machine to call, and then manually type in the BP number and send it to the memory through the guò computer, and wait for the call queuing system to extract it.

……

The functional block diagram and schematic diagram of the transmission system, Jiang Xinwei is very handy in drawing, that is, the software program process for the processor is also very smooth, but when he went deep into the circuit design, Jiang Xinwei found that the matter was big, and he was a little speechless: because his biggest headache was how to design the PCB circuit board.

PCBs are often referred to as printed circuit boards, which are thin layers of copper laid on top of plastic boards. Not to mention the regular electronics factory, even people with a little knowledge of chemistry know how to do it, that is, to coat the copper layer to be used with a protective film, and then throw the whole board into the corrosion liquid for corrosion, and remove the unwanted copper layer.

But why was Jiang Xinwei stuck by this low-tech thing?

The main reason is that he doesn't have good PCB design software, only a low version of protel software, which is still obtained from Shuangzhou Institute of Technology by Shengli Electronics No. 2 Factory, not to mention that Jiang Xinwei is not used to it, and he is not suitable for such a complex circuit diagram at all.

Come on, tens of thousands of lines, even if you don't make a single mistake, it's hard to finish it for a few years with a T-ruler and a pencil.

On the other hand, there is no manufacturer in Yiyang City that can process multilayer printed circuit boards. Shengli Electronics No. 2 Factory said that it was an electronics factory, but in Jiang Xinwei's view, it was just a small workshop for the assembly of electronic components, and the technology of making circuit boards was only the most basic level, and it could only make simple double-layer circuit boards for radios.

Jiang Xinwei was very depressed and had to put down his work to investigate whether there were any circuit board processing manufacturers with slightly stronger technology in Yiyang City and the surrounding areas.

In the end, I finally found an electronic processing factory belonging to the military in Zi'an City, which was able to barely process multi-layer circuit boards that were not very complex.

Faced with this situation, Jiang Xinwei decided to stop these underlying designs first, first use multiple computers, and use the borrowed industrial computers that can be found in surrounding enterprises or schools to assemble, and verify that the wireless paging and transmission system he will develop is correct in principle.

When the principle is verified and the relevant parameters are obtained, he will work on the underlying design in turn.

Jiang Xinwei has the confidence to do this, because he still has one trick that he hasn't used, that is, the Italian he met before-Frankl, should be of great help.

You can ask him to help you build a set of state-of-the-art PCB design software, and at the same time ask him to help you process some complex circuit boards in Italy. If that's the case, you'll save a lot of time and effort, and the underlying design will be twice as effective with half the effort.

What made Jiang Xinwei happy was that Su Dingyu, Director Wei, and Huang Xigui of the factory did not come to disturb him, and only came to ask for advice when the telephone failed to pass the acceptance and they could not find the reason.

Now Director Wei has obtained the telephone agency contract of the post and telecommunications equipment company. Because Shengli Electronics No. 2 Factory agreed to pay 40 yuan per unit for brand usage and network access license fees, they are naturally willing to hand over the products to Shengli Electronics No. 2 Factory to sell, which is equivalent to sitting at home and collecting money. What's more, the contract stipulates that Yiyang City and the counties and towns under the jurisdiction of Yiyang City will still be sold by the Post and Telecommunications Equipment Company, and the Second Shengli Electronics Factory will take away the market that they can't go to, and they have no loss at all.

In their opinion, Shengli Electronics No. 2 Factory is purely desperate, thinking that it can sell products with an advertisement, which is really funny: Now there are more manufacturers who advertise, and how many of them have succeeded? Many people have been made worse than dead by the additional advertising costs, and if it was so simple, they would have gone to advertise a long time ago.

In order to ensure that they can receive the money, the post and telecommunications equipment company also deliberately set up a difficult problem for Shengli Electronics No. 2 Factory, that is, they must ensure that the monthly sales volume exceeds 50 units, and less than 50 units are still settled according to the brand of 50 units and the use fee of the network access card. If Shengli Electronics No. 2 Factory does not settle this fee for more than one month, the Post and Telecommunications Equipment Company has the right to withdraw the right to sell telephones.

Originally, Director Wei disagreed with this "overlord" clause, because he was worried that his factory would not be able to sell telephones at all, but Su Dingyu persuaded him to agree.

Jiang Xinwei also agrees with this: If you can't sell 50 units every month, it's better to get rid of it as soon as possible.

In Jiang Xinwei's view, this kind of clause is very common in the future, and it is not too much, and after Shengli Electronics No. 2 Factory has its own new products in the future, it will definitely recruit agents, and then he can also come up with this kind of clause for others to sign. Secondly, Jiang Xinwei believes that this is an experimental cooperation, a kind of transition before the factory becomes formal.

The next step is to see if the ad is effective.

(Thank you for your ten thousand rewards, there is a change in the evening)
