After getting Hong Qing's assurance, Yao Fei also put his mind at ease for the time being, and then it will be up to these guys to do what they do.

Now, after more than a month of intense and orderly time, the production equipment in the workshop has been in the commissioning stage, and the scientific research building is currently under renovation.

However, even so, for those high-tech talents, from the moment they came to the company to report, they had already invested in the technical preparation of the full system of wireless paging system planned by Yao Fei.

Don't have a lab yet? Don't have a research facility? It doesn't matter, can't they make a detailed list of the equipment needed for this system one by one?

In addition to the receiving terminal pager, the hardware of the wireless artificial paging system also includes a base station transmitter, a link transmitter, a paging console connected to the base station transmitter, a paging data processing center, and a supplementary point transmitter.

Each of these transmitters will be applied to a number of technologies, and the job of these people is to start from each part of the system, carry out the early technical cracking, crack to every circuit, every electrode, and list the application of technical details, and at the same time separate the common technology and patented technology.

As for the software, it is only a set of transmitter operation and control software, which does not need to be as complex as the automatic paging system.

The entire teaching building of the Wan Chai campus has been fully utilized, and each classroom represents a technical research group, and now Bentley and Hillis have been freed from the bitterness of the interview, but they have immediately devoted themselves to the guidance and research of the theoretical technology of the wireless manual paging system.

"Melinda, how many technical researchers are there so far? What is the ratio of programming to hardware skills? ”

After Yao Fei dismantled the wireless paging system, he handed over the task of cracking it, and now, he is rarely directly involved in the research and development of technical technology, and basically does things in technical guidance and decision-making.

"Boss, a total of 182 people, 129 people have come to work, including 31 programmers, 98 hardware technicians......"

Glancing at the personnel statistics table in her hand, Melinda quickly replied.

"We will continue to increase our recruitment efforts, and in the coming period, our company will need to study a lot of projects, far more than this wireless paging system, we need a large number of technical experts.

At the same time, relax the conditions for the recruitment of professional technical college students, since we can not recruit enough high-tech technical personnel in the short term, then we can train these college students, they can do the systematic work they can't do well, then they can do specialized work, practice makes perfect, as long as we high-tech technical experts can be divided into section number project modules, then we can also achieve our research purpose!

Mr. Hillis, where is the current progress in the research on pager technology? ”

The development project of the paging control system can be delayed, the research project of the radio transmitter can be delayed, and the paging data center project can be postponed, but only the technical research of the pager is not good, and the digital pager has long been on the market.

"Mr. Yao, the first phase of the research work has been completed by my research group, and is currently moving forward to the next stage of research work, at present, I will divide the design of the pager into six modules, including shape design, circuit system design, signal receiver, codec design, operating system module and screen display module.

We can design the shape, circuit system, and operating system by ourselves, but we will inevitably use the patented technology of Bell Labs and Motorola to design the other modules, and if we can't solve these patent problems, we will be sued in court......"

Although Hillis, who is 25 years old this year, is young, he is a real technical master, and has always been one of the most famous computer scientists in the world, and when he was still at MIT, he began to design the parallel supercomputer he conceived, and when he graduated, he already had 17 personal patents.

"What are these patents?"

When it comes to patents, Yao Fei has a bit of a headache, with the continuous expansion of the company's business field, patent collisions are inevitable, a pager involves a number of patented technologies of other companies, if a complete set of wireless paging system is done, then how much, thinking of this Yao Fei couldn't help but rub his temples.

"A total of 8 core patented technologies, we can't bypass, including Bell Labs' coding modulation and demodulation technology, Motorola's electronic level signal reception and conversion technology, LED liquid crystal display array technology, signal wave filtering technology, coding technology, ......"

Opening the notebook he had with him, Hillis gave the specific names of the patents.

"Coding technology can not be considered, we can use ASCLL code technology to replace the existing digital coding technology, other technology patents, I will arrange people to contact them in the near future...... "I have to lose myself a BUG, otherwise I just broke in, so many patent obstacles, even if I make money, most of them are not into other people's pockets.

"Mr. Yao, don't use POCSAG coding?"

Now the pager on the market can only display the numbers 0-9, which means that they have not successfully integrated the POCSAG code into the pager, which is a set of codes researched by the British General Post Office for wireless paging systems.

Compared with the BCD code used on the current digital pager, the POCSAG code has a natural advantage, this set of POCSAG code has the advantages of high coding efficiency, strong error correction ability, large address capacity, etc., using this set of code, only need to pay a small fee to the General Post Office, you can obtain its authorized use license.

For these pager manufacturers, it completely saves a lot of manpower, material and financial resources and valuable time required for self-coding, and what needs to be done is just to think about how to replace the original BCD code with this set of codes.

But since there is such a ready-made, low-cost and very effective coding technique, why did Yao Fei abandon it and use ASCLL code instead?

Didn't famous pager manufacturers such as Motorola and Panasonic notice the ASCLL code?

It is impossible not to notice that compared to the POCSAG code, the ASCLL code appeared more than ten years earlier than the former, and it has also been successfully used on computers.

So why did these pager manufacturers finally choose the POCSAG code as the pager code?
