Rebirth 1984: Starting from the development of Hanka

Chapter 120 Prepare for a rainy day, the layout of mobile communication
The next day, Zhao Ye and others moved into the Mahler Villa.

Villa Mahler is like the "Princess Castle" in fairy tales, covering an area of ​​more than 5000 square meters and a garden area of ​​nearly [-] square meters.Norwegian minarets, Gothic roofs, Chinese glazed tiles, and dark brown Taishan facing bricks.A pair of stone lions are placed at the entrance like a traditional Chinese mansion, and the garden is planted with rare flowers and trees such as cypresses and cedars.The interior is decorated like a luxury cruise ship, with shiplap-shaped windows and seagrass-patterned floors.

In the previous life, if one wanted to buy such a large villa, the price would have exceeded 10 billion RMB, which would probably be far more than that.

Zhao Ye was sitting under the shade of a tree drinking some wine, blowing the summer breeze, feeling infinitely emotional.

There are still many old houses like the Mahler Villa in Shanghai, and their value increases every year.

If you buy these old houses now, even if you sell them in the future, you will definitely make a lot of money...

……

Wujiang Group, Communication Division.

"Boss, the research of Hanxian BB machine has made a great breakthrough. The important part of BB machine - the decoder can decode the signal sent by the base station into Chinese characters, and then display it on the monitor!"

"In addition, it can also display English letters."

Lu Jia, head of the communications division, introduced.

Zhao Ye also rushed here because he received this news.

He looked at the experimental table, the words "Wujiang Group wujiang" appeared on the LCD screen of the BB machine, and he couldn't help showing a hint of joy on his face.

The progress of the communication business department exceeded his imagination.

"Very good, perfect it as soon as possible, and then realize mass production!" Zhao Ye said.

Right now, the digital BB machine market is highly competitive, and there are many BB machine brands on the market, such as Imagine, Motorola, Ericsson, Panasonic, Sony, Hitachi, and Sharp.

As the earliest brand of digital BB machines, Imagine-BB machine currently occupies the largest market share, but only 34.1% of the market share is eaten away by other brands.

Once the Hanxian BB machine is released, it will definitely be able to regain the market.

It is said to be a Chinese display BB machine, but it can actually display English letters and numbers.It is no problem at all to sell Hanxian BB machines to English-speaking countries.

Of course, the languages ​​of other countries, such as Japanese, only need to develop corresponding decoder software, but technically, they are similar and slightly different.

However, the paging stations are basically manual paging stations at present.

With the increase of BB machine users, manual paging will be too busy.

Automatic paging requires the development of program-controlled switches.

Moreover, the future development direction of the Chinese display BB machine is a two-way Chinese display BB machine.

As for the two-way Chinese display BB machine, what does it mean?Very simple, that is, you can send text messages to another BB machine through this BB machine.

In the previous life, Motorola had developed this two-way Chinese display BB machine, which exploded in China.However, the product release time is a bit late.

BB machines were already obsolete at that time, and were slowly replaced by mobile phones.

If the two-way Chinese display BB machine can be developed earlier, then this product will be popular all over the world and make a lot of money.

Chinese people like to send text messages, and foreigners also like to send emails.

It is difficult for the two-way Chinese display BB machine to be unfired.

However, before developing the two-way Chinese display BB machine, it is necessary to develop the program-controlled switchboard to realize the automatic paging function of the paging station.

Later, Zhao Ye called the directors of the communication department to the office for a meeting.

Zhao Ye first praised the work of the Communication Division, and then mentioned the two-way Chinese display BB machine and the program-controlled switchboard.

"To develop a two-way Chinese display BB machine, we must first develop a program-controlled switchboard! Moreover, the program-controlled switchboard is not only used for automatic paging of the BB machine, but also for making calls and automatically dialing to the telephone."

Although there are few mobile phone users in China, there are many fixed-line telephones. Institutions, governments, scientific research institutions, schools, private enterprises, etc. use a lot of fixed-line telephones, so they need to use a large number of program-controlled switches.

Huawei started as a program-controlled switch. In 1990, Huawei began to develop program-controlled small switches, with more than a dozen employees. In 1992, the company's sales exceeded 1 million yuan, and in 1994, the sales volume was 8 million yuan.

It can be seen that the domestic communication market is still very huge.

It is only 1986 now, and Wujiang Company is doing program-controlled switches at this time, much earlier than Huawei, and technically, it is not comparable to Huawei at this time.

In the conference room, Zhao Ye ordered the Communication Division to set up a program-controlled switchboard development team with a tentative number of 25 people.

After pondering for a moment, Zhao Ye thought to himself, since Wujiang Group wants to get a share of the communication market, it should simply make a good layout at one time.

After a pause, he continued: "Mobile phones are the trend of future communication. BB machines will be eliminated sooner or later. We need to prepare early and plan ahead. The communication business department will allocate some part to set up a mobile phone development team. The more people the better!"

"In addition, we need to study communication network standards, that is, wireless technology standards. Europe is currently studying GSM. Although this communication technology is good, I am more optimistic about another communication technology!"

Zhao Ye said, walking on the big stage, there was a black block in this small meeting room, Zhao Ye took out a pen, and wrote on the blackboard the words "Code Division Multiple Access", which is CDMA.

In the previous life, Qualcomm was almost monopolized in the CDMA field, so in the smartphone market, there was a well-known "Qualcomm tax", which is quite overbearing. Every mobile phone brand in the world has to pay the "Qualcomm tax", even Apple Companies are no exception.

Qualcomm uses its large number of patents in communications to sell its own chip packages and requires major manufacturers to pay 5% of the price of the whole machine.

The profit of many mobile phone manufacturers is less than 5%. Qualcomm makes more money than other mobile phone companies. Who can bear it?Chunchun is working for Qualcomm.

Qualcomm was founded in 1985. It has not yet set foot in CDMA technology, but is engaged in other products. It was not until 1989 that it challenged the traditional wireless technology standards, and then launched Code Division Multiple Access (CDMA) technology—its It emerged that forever changed the face of global wireless communications and became the industry standard in 1993, and by 1999, the International Telecommunication Union selected CDMA as the technology behind 3G.

If it weren't for the relatively slow emergence of CDMA technology, Europe's GSM would not be an opponent at all.

Anyway, in this life, Zhao Ye wants to keep CDMA in his pocket, learn from "Qualcomm" and start a "borderless tax".

As long as Wujiang Company develops CDMA technology as soon as possible, China's communication department will definitely choose Wujiang CDMA as the second, third and fourth generation mobile communication standards.

If you can go abroad, it will be more joy than joy.

At this time, Zhao Ye was explaining to his employees what CDMA code division multiple access technology is.

At present, only Zhao Ye is familiar with this technology. If they don't explain it clearly to them, they won't know how to develop it at all.

However, the development of CDMA is quite difficult, and there should be no major progress in a short period of time, unless Zhao Ye leads them to study CDMA all day long.

But Zhao Ye has other things to do, so he doesn't have so much time.In addition, CDMA technology is too advanced and may not be suitable for China.

It is said that one step ahead is a martyr, and half a step ahead is a pioneer.

Just half a step ahead of Wujiang Group.

The development of CDMA technology is for the future.

Right now, there is actually another mobile communication technology that is more suitable for China's national conditions, and that is PHS.

PHS technology is not only very popular in China, but also very popular in many countries.

Because what PHS uses is a micro-cellular technology, the cost is low, and it is more suitable for densely populated cities.

A GSM mobile phone normally costs [-] to [-] yuan; a PHS mobile phone costs several thousand.

In addition, PHS has low power consumption, extremely small electromagnetic wave radiation, and is less harmful to human radiation. It is loved by some special groups, such as the elderly, pregnant women, and medical personnel.And the standby time is long, saving power.With one charge, the standby time can reach 10 days, which saves you the trouble of frequent charging.The call quality of PHS is comparable to that of fixed-line telephones within the coverage area of ​​the network; unlike wireless Internet access shared by multiple people on mobile phones, PHS Internet access can exclusively enjoy 64/128Kbps bandwidth.

In addition, PHS does not require a mobile license.In the previous life, China Telecom and China Netcom chose PHS because they did not have a mobile license, and seized a large number of users before 3G.

Of course, the shortcomings of PHS are also very obvious, otherwise it would not be replaced later.

There are two main disadvantages. The first is that it cannot roam the country. PHS cannot roam the country like a mobile phone, so it can only be used as a "supplement and extension of fixed-line phones", and there is always a gap between mobile phones and mobile phones in terms of functions.

Second, poor coverage.Generally limited to urban areas, the signal is poor; there are few base stations, and calls are not smooth in some parts of the city, and calls cannot be made in case of a power outage.

However, as far as the current domestic situation is concerned, it is already very good to have PHS, so what "bicycle" is needed?
Before you know it, it's almost time to get off work.

Zhao Ye talked a lot about Code Division Multiple Access (CDMA) technology today. As for PHS technology, I plan to talk about it in a few days.

There are so many technologies launched at once, and there are two-way Chinese display BB machines, program-controlled switches, mobile phones, cdma and PHS.The manpower of the Wujiang Communication Division is obviously insufficient.

The Wujiang Group had no choice but to continue advertising in newspapers and television, and at the same time let foreign headhunters poach some talents to work in China.

However, during this period, there are not many talents who are willing to work in China.

Many students studying abroad in the United States, once they arrive in the United States, they don't want to come back.

Zhao Ye was deeply ashamed.

Facing an increasingly urgent talent gap.

Zhao Ye felt the need to act...
