Video Game Empire

Li Xuan picked up the mobile phone and called his assistant back. ◎Top novel, Li Xuan put Guan Zhilin aside for several days before. And Guan Zhilin noticed that Li Xuan was intentionally ignoring her, so she obediently returned to the studio the next day to shoot, and she didn't dare to do anything else.

In the past few days, Guan Zhilin made several calls to Li Xuan's office every day. Because she had never been able to speak to Li Xuan, she finally made up her mind to go to the Central Headquarters of Dongfang Electronics Company to meet Li Xuan. Fortunately, this beauty Guan did not go directly to the building to block Li Xuan, but found a cafe nearby and kept calling to see him.

And Li Xuan happened to be out of the office today, so Ke Lilun was tragic. After receiving a call from the boss's Xiaomi, he could only reply softly that the boss was not there. But Guan Zhilin was rejected by Ke Lilun for several days before, thinking that he was shirking himself again. So, Guan Zhilin kept on making phone calls with perseverance, and finally, Ke Lilun couldn't hold it anymore and could only ask his boss for help.

"If she calls again, you can tell her that I will let her act obediently, and I will go see her when I have time!" Li Xuan hung up the phone with a smile on the corner of his mouth.

Guan Zhilin is not stupid, she obviously knows Li Xuan's character. If she dares to go directly to Li Xuan's office to block people, it is estimated that tomorrow's Hong Kong newspapers will be overwhelmed by Li Xuan's scandal. In that case, Li Xuan would kick her away without hesitation. But now, Li Xuan is willing to continue to play a training game, after all, Guan Zhilin is one of the most beautiful women in Hong Kong.

Of course, these are just some of the little fun in the rich and colorful life of Li's richest man, and his focus is still on his career. Because if there is no huge wealth brought by his career, Guan Meiren and Li Meiren are naturally impossible to bow their heads and obey him.

Li Xuan was not in a hurry to hand the brick-like mobile phone to the assistant beside him. Instead, keep playing with it. This is Motorola's launch just last year; the 8000x portable mobile phone, hailed by later generations as the originator of the modern mobile phone.

Its portability is reflected in the overall length of the fuselage does not exceed 20 cm. The phone weighs only 2 pounds (900 grams). Perhaps for mobile phone users three decades from now, this kind of backwardness needs to be swept into the trash long ago. But in 1983 it was an epoch-making product, which meant that human communication began to enter a new era.

Hong Kong is one of the earliest regions in the world to build a mobile communication network. The Hong Kong Telephone Company, which Li Xuanzheng is about to acquire, obtained the exclusive right to operate mobile communication from the Hong Kong government as early as last year, and built a complete mobile communication network with signals covering the entire urban area of ​​Hong Kong. communication system.

This is also one of the important reasons why Li Xuan is happy to acquire the Hong Kong Telephone Company. Aspiring to enter the communication field, especially the future mobile communication field, Dongfang Electronics Co., Ltd. needs a terminal telecom operator to experiment and promote its products.

The history of mobile phones can be traced back to 1940, when Galvin engineers developed it for the U.S. Army. Portable FM wireless walkie-talkie. That's right, the principle of the first generation of analog mobile phones, to put it bluntly, is to convert the voice into an FM radio through the chip and send it out. Therefore, the confidentiality of the analog mobile phone is actually very poor, and the signal sent by the mobile phone can be received by the FM radio, and it is not difficult to crack it.

In the 1960s and 1970s, under the huge demand of police, taxi drivers and other industries, the market of car mobile phones in the United States expanded rapidly. In 1973, Martin Cooper, a senior engineer at Motorola, developed a prototype mobile phone based on a cellular mobile communication system on the basis of a car mobile phone. That is; the predecessor of the 8000x.

However, it took Motorola nearly 10 years and hundreds of millions of dollars in research and development funds to finally make a major breakthrough in portability and low energy consumption and successfully commercialize it. ;8000x phone with battery installed. Can only maintain half an hour of talk time. This is weak compared to a certain domestic brand that charges for five minutes and talks for two hours in later generations. However, the price of this analog phone in the United States is as high as 3,995 US dollars, and the price in Hong Kong is as high as 30,000 Hong Kong dollars, but it is still warmly sought after by high-end people.

It is from then on that Motorola began to dominate the entire 1g era. Until the 2G era kicked off in the 1990s, Motorola was due to its own mistakes. It gradually lost its leadership in the field of mobile phones. In the later 3G era, Motorola dropped out of the mainstream competition. This history of decline has made countless people sigh.

But turn the clock back 30 years, and now Motorola is entering the most glorious stage of the company. In fact, as early as two years ago, under the instruction of Li Xuan, the Oriental Research Institute began to vigorously enter the research and development in the field of mobile phones, but it is still a while away from producing mature works.

And even Li Xuan himself has no confidence that he can surpass Motorola in the simulation era. The most important wireless transceiver module (antenna part) and audio input and output module (earphone speaker part) in analog mobile phones belong to analog circuits.

Don't look at the erm architecture and architecture that the Oriental Research Institute has successively developed that shocked the entire semiconductor industry. However, the Oriental Research Institute can only dominate the field of digital chips at most. If it is not because it has just acquired Fairchild, the foundation of Oriental Electronics in the field of analog chips is almost zero.

The field of analog chips is the field that needs the most accumulation. With the maturity of CAD (computer-aided design) software in recent years, the work of digital chip designers has become easier. Many module design work can be replaced by computer only by inputting parameters in special software. The help of computers allows designers to challenge more complex and high-performance chip designs.

But in the field of analog chips, even after 30 years, most of the design and testing work still requires designers to do the whole process. For example, digital chips do not need to consider the layout of components at all, but analog chips do not. Especially like the power amplifier chip in the speaker, the different positions of the resistor and capacitor will bring about completely different noise interference and distortion interference, which requires the designer to obtain the best solution after numerous experiments.

We often hear how many transistors a chip integrates. The greater the number of integrated transistors, the more powerful the chip is. The number of integrated transistors in the fifth-generation Core in later generations has reached 1.9 billion.

Human energy is limited. Pure hand design also limits the infinite complexity of analog chips. It is impossible to design a circuit with an integration level of hundreds of millions of transistors only by hand. And the limit of integration. In turn, it will greatly limit the designer's thinking. For example, in the design of analog chips, designers will try to avoid designing large-capacity capacitors and high-value resistors to improve the integration of the chip.

These difficulties and limitations make the design of analog chips often take time to accumulate. Taking audiophile-grade audio as an example, digital equipment such as players are of similar standard of various manufacturers. However, in terms of the quality of analog equipment such as speakers, world-class companies such as Japan's Sony and Pioneer have been unable to produce high-quality speakers from the United States. The reason is that the power amplifier chips developed by Sony and other companies cannot reach those old factories in the United States with decades or even centuries of history.

And the same. Motorola's dominance in analog cell phones is simply beyond the reach of other companies. In fact, until the 2G era, Motorola's ability to take over the signal and call voice fidelity is also the best among the world's major mobile phone manufacturers. And this module is precisely the use of analog chips.

The Galvin company, which developed walkie-talkies for the U.S. military before World War II, changed its name in 1947, and its new name was Motorola. It can be said that from the walkie-talkie in 1940, to the later car mobile phone, and then to the current portable mobile phone, Motorola's technological monopoly is almost the same.

In fact, Motorola did not take much advantage of the first generation of mobile communication standards. The world's first commercial cellular network was built in Tokyo in 1979 by a Japanese company (Nippon Telegraph and Telephone Corporation). after. Two Nordic companies, Ericsson and Nokia, jointly developed the nmt-450 analog communication system. So since 1981, the nmt-450 system has been put into commercial operation in Finland, Sweden and other Nordic countries.

In the US market, Bell Labs submitted a proposal for cellular mobile services to the (Federal Communications Commission) as early as the end of 1971. And in 1978 successfully built the first trial network in Chicago. Last year, the mature amps system developed by Bell Labs was officially approved, and the commercialized basic signal network began to be built in the United States.

And Motorola itself is developing the standard. Not really mature yet. But Motorola failed to take the lead in the field of communication equipment, but relied on; 8000x this mobile phone successfully pulled a game.

Compared with Ericsson, Nokia, Motorola, these giants in the communication field. The layout of Dongfang Electronics in the field of communication has just started. The previous ds-2000 digital program-controlled telephone exchange can only be regarded as a test of water.

In the field of mobile communication, Li Xuan has already focused his attention on the next generation of communication standards. Such as tdma and cdma technology.

The Chinese translation of the former is called time division multiple access technology, and the gprs in the 2g era is based on tdma technology. In the 1g analog era, every mobile phone needs to occupy a channel when talking. The frequency band allocated to the mobile communication field by each country is limited. For example, the United States allocates 824-894mhz. Therefore, in a limited frequency band, the channels that can be divided are also limited, which limits the total number of users that the system can carry.

In fact, when people are talking, the pause time between voices is actually very long. As long as the voice coding is done reasonably, several users can share a channel. And tdma technology is based on this principle, evenly distributes a channel to 8 or even 16 users to use at the same time, which greatly increases the number of users that the system can carry.

As for the more advanced cdma technology, its large-scale application did not really explode until the 3G era. Qualcomm almost built a huge wall outside the cdma patent pool, so that all Chinese mobile phone manufacturers in later generations were ruthlessly exploited by it, and finally attracted the National Development and Reform Commission to resort to anti-monopoly measures.

Although Li Xuan doesn't know much about the specific technology, he gives a general principle, which is enough for professional technicians to see the direction of research and development. It is believed that after five to eight years of accumulation, when the second-generation mobile communication standard is officially launched, Dongfang Electronics should already have enough patents to make it the maker of the rules of the game.

Li Xuan's current layout in the field of mobile communications, in addition to basic communications patents, also includes dsp (digital signal processor) chips. In the era of digital mobile phones in later generations, every mobile phone needs a dsp chip, which is also one of the largest types of digital chips in the market.

But now, the reason why Li Xuan is eager to acquire the Hong Kong Telephone Company is that the Oriental Research Institute has just developed a new gadget-card. A card is a plastic card with an integrated circuit chip inside. Cards in later generations are widely used, including bus cards, social security cards, medical insurance cards, bank cards, and meal cards in university cafeterias. In the early days of China's earliest wafer fab, Hua Hong relied on the country's social security card orders to support it~www.readwn.com~ In fact, as early as 1969, the Japanese Mura Kunitaka proposed a method of manufacturing a safe and reliable credit card. And obtained a patent in 1980. He named his card the id card. In fact, the id card already has the prototype of the card technology. In the 21st century, the bank cards and credit cards that originally used magnetic cards were really like the village filial piety. Replaced by a more secure card, as previously envisaged.

The world's first card was developed by Bull as early as 1976, but its specific application has not made much progress. Boolean has been lobbying France's General Post Office to apply it to telephone cards.

The Eastern Research Institute's idea this time is exactly the same as that of the Bull Company, and it also hopes to apply the card to the phone card. The Hong Kong Telephone Company owns the franchise of all local telephones in Hong Kong, and all the basic telephone communication facilities in Hong Kong are invested by the Hong Kong Telephone Company. Another Hong Kong Dadong Telegraph Office is basically only responsible for investment in transnational lines, and most of the user tariffs are settled through the Hong Kong Telephone Company.

If Li Xuan can acquire the Hong Kong Telephone Company, it will be much easier for it to apply to the Hong Kong government to promote the use of telephone cards to replace the current magnetic card telephone cards. And once the calling card is successful in Hong Kong, Orient Electronics can quickly take this as an example and promote it to other markets in the world. (To be continued..)
