"Li Sheng, a digital mobile phone that can realize basic functions such as making calls, sending and receiving text messages, etc., usually consists of five parts. These five parts are the radio frequency part, the baseband part, the power management, the peripheral components and the system software.

The radio frequency part is responsible for the transmission and reception of information data, and its quality directly determines the call quality of the mobile phone. Motorola's big brother can beat other brands because its radio frequency system is very good, and it can maintain high-quality call quality in places where other mobile phones can't receive signals.

The role of the power management part should not be underestimated, because the battery power of the mobile phone is very limited, so the level of power management directly determines the standby time of the mobile phone. If the standby time of the mobile phone is too short, then even if its function is excellent, the practical application value will be greatly reduced!

The core of these two parts is naturally the radio frequency chip and the power supply chip. The M-88 digital mobile phone we launched this time adopts the RF chips and power chips provided by Fairchild Semiconductor. "Liu Yu, the chief person in charge of the entire mobile communication project team of the Oriental Research Institute, is accompanying Li Xuan at the moment to give a detailed technical explanation for him.

Hong Kong Telecom has started the trial operation of the CDMA digital mobile phone network. Naturally, Li Xuan should take a closer look at the development of the mobile communication business under the Oriental Group. The Oriental Research Institute is the leader of the entire digital mobile phone project research and development plan, so Li Xuan naturally preferred to come here to check the situation.

On the other side of Tai Po Road, Shatin, Hong Kong, across the road from the Chinese University of Hong Kong, the scientific research building of the R&D Center of the Oriental Research Institute Headquarters has been increased to eight buildings after continuous expansion. In addition, around the Hong Kong R&D center of the Oriental Research Institute, the Hong Kong government has also established a large area around it and established the Sha Tin Science and Technology Park.

To this end, the Hong Kong government specially established the Hong Kong Science and Technology Park Company under the Department of Economic Affairs, which is responsible for the unified management and operation of the Shatin Science and Technology Park, as well as the Fotan Industrial Park, which has gradually become a high-tech electronics industry cluster, and the Hong Kong Electronics Industry Park established in Tin Shui Wai, Yuen Long. garden.

In another time and space, Shatin is one of the largest satellite towns in Hong Kong, apart from Hong Kong Island and downtown Kowloon. Its main role is to share the increasingly unbearable population pressure in the urban areas of Hong Kong and Kowloon. Even in the 21st century, Sha Tin is still lackluster except for a racecourse.

In this time and space, due to the emergence of the butterfly of the Oriental Group, Shatin seems to have begun to develop into a high-tech industry cluster. Fotan Industrial Park has become Asia's most famous, small business incubation base and venture capital gathering place.

The original Ma Liushui, where CUHK is located, has also become a research holy land for countless technicians across Asia due to the establishment and expansion of the Hong Kong R&D Center of the Oriental Research Institute. Many inventions that affect the entire human race have been born or are being conceived here. For example, ERM, the most widely used processor chip in the world, was born here.

The world's first commercial digital mobile phone, M-88, was also born in the Oriental Experimental Building next to Dapu Road in Ma Liushui. The development process of mobile phone is a huge system project, and Dongfang Group can proudly announce that they can support such a huge system development project through continuous development.

For example, RF chips and power chips are provided by Fairchild, which is responsible for the analog semiconductor business of the Oriental Group. The system software of the mobile phone is developed by Dongfang System Software Company. The peripheral components of the mobile phone, such as the STN black and white LCD screen, are manufactured by the peripheral company Xincai Optoelectronics.

"The baseband part is the core part of the entire mobile phone, and the entire baseband system consists of a central processing unit, a digital signal processor, a channel encoder, a modem, and an interface module.

On the M-88, each module of the baseband part is still independent and scattered, but we have started the integrated research and development of the baseband chip, hoping to integrate them into a SOC chip. This can not only greatly reduce the power of the mobile phone, but also reduce the overall design difficulty of the mobile phone. "Liu Yu pointed to a completely dismantled mobile phone in front of the two, and introduced the function of each key chip to Li Xuan one by one.

The "M" of "M-88" refers to "Mobile (mobile phone. In the baseband system of "88"-88 mobile phone, the CPU (central processing unit) uses the ERM architecture of the home of the Oriental Group. In another time and space, the ARM architecture has turned around in the mobile phone industry and has become a processor architecture that can be as famous as Intel's X86 series.

The DSP (digital processor) in the M-88 baseband system is also a technology acquired by Li Xuan from Texas Instruments at a considerable cost. When the mobile phone industry begins to break out, Deyi estimates that even the intestines will regret it.

On the bright side, it seems that Li Xuan did not personally participate in the development of this M-88 digital mobile phone, but in fact every step of it is under Li Xuan's control. Whether it is the basic communication technology - CDMA, or the specific mobile phone design layout, Li Xuan has made plans behind the scenes.

Listening to Liu Yu's introduction beside him, Li Xuan kept nodding his head. He will only point out the general direction of research and development, so that the people below will take less detours. But every scientific research result is still needed, and researchers spend countless ingenuity to explore. Dozens or even hundreds of scientific research achievements can be assembled together to create a practical scientific and technological product.

Li Xuan had seen an internal audit report of the group. The total investment of the Oriental Group in the field of mobile communications over the years has almost approached 1 billion US dollars. This is by no means a small sum, but Li Xuan feels that it is very valuable.

Because the income obtained by the Oriental Group is by no means only the M-88 mobile phone. With the transformation of mobile communication from the analog age to the digital age, Oriental Group hopes to take the lead in the entire industry.

For example, Sweden's Ericsson began to intervene in the emerging mobile communication equipment market with the help of Nordic's NMT analog cellular system. And through Europe's GSM digital cellular system, Ericsson has rapidly grown into the world's largest supplier of mobile communication equipment.

In the field of communication equipment, the Oriental Group also started its layout early. For example, the DS series digital program-controlled telephone switches produced in cooperation with China have been in the domestic market in recent years, and they have almost completely squeezed other competitors out of the Chinese market.

The telecommunications equipment market is a field with a relatively high degree of monopoly, and it is not easy for Orient Group to defeat established European and American companies in traditional telephone exchanges and other markets. In the emerging field of mobile communication equipment, everyone has returned to the same starting line.

What's more, Dongfang Group now has a huge advantage for me, that is, CDMA technology has been commercialized ahead of time compared to the GSM technology being developed in Europe. According to the intelligence spied on by Dongfang Commercial's channels in Europe, it will take at least one to two years for GSM to achieve technical maturity.

If CDMA technology fully demonstrates the excellent performance of its own technology to global operators before the advent of GSM, it will undoubtedly gain a more favorable opportunity in the standard competition in the next 2G era.

"Li Sheng, compared with traditional analog mobile phones, digital mobile phones have not only made a leap in call quality and call confidentiality, but also have more functions in mobile phones. For example, our M-88 has caller ID, Voicemail, text messaging, and more!

Especially text messages, that is, sending and receiving text messages, can greatly reduce the frequency of calls made by users. Those concise, non-essential exchanges can be communicated by text messages, which greatly reduces the cost of calls! "Liu Yu began to introduce the advantages of digital mobile phones.

Li Xuan, as a past person, is naturally clear about this. SMS is one of the most important functions in the 2G era, especially in developing countries like China. Due to the high pricing of mobile phone call charges in the early days, the frequency of SMS usage is much higher than that in European and American countries.

When he was at HKT, Li Xuan, like company president Gu Xinping, emphasized the new technology of SMS. SMS can be an important breakthrough for operators to promote the low cost of digital mobile phones. The cost of a text message is HKD 0.1, which is much cheaper than a phone call, and everyone can afford it!

In addition to SMS, another important innovation in the 2G era is the beginning of the mobile Internet. Of course, the M-88 in front of Li Xuan also has the function of surfing the Internet, but the important role of the mobile Internet has already surpassed the basic function of making phone calls in the future. Therefore, mobile networking technology will be another R&D focus of the Oriental Research Institute in the field of mobile communications.

After all, a person's energy is limited. For example, Li Xuan now has to spend time managing a multinational group with a total number of tens of thousands of employees. He also has to deal with several women, pay attention to the growth of the family and children, and the rest will be personally The time to participate in scientific research is naturally very small. It has been a long time since he stayed in the laboratory for several days like the original public relations ERM structure, and now even when he comes to the R&D center here in Shatin, he occasionally goes around.

The same is true for a company and a project. The mobile communication development team can be regarded as one of the largest teams under the Oriental Research Institute. It participates in the research and development of basic communication equipment, and also participates in the development of the underlying communication technology. The realization of specific mobile phone functions.

This kind of large and comprehensive structure, if not for Li Xuan's rebirth of golden fingers, to point out clear ideas to all aspects, it will inevitably lead to a decrease in efficiency. Everyone has become a group of headless flies, not knowing which aspect is the priority that needs to be prioritized.

Therefore, after the mobile communication project achieved phased results, Li Xuan felt that it was necessary to carry out a split, just like the previous LCD project. However, compared with the previous LCD project, which was completely split into independent subsidiaries, the mobile communication project is larger and more complex. According to Li Xuan's plan, the research and development of the underlying basic technologies in the project team is still retained in the Oriental Research Institute. For example, CDMA (Code Division Multiple Access) communication technology will be launched in the future in the form of patent authorization.

As for those application-level research and development, they are all independently split into a new subsidiary. Li Xuan has even thought about the name of the new company, and it is called Huaxing Mobile Communication Technology Company. In later generations, there were two very famous communication equipment manufacturers in China, and Li Xuan simply took a word from these two companies.

Huaxing, okay, the name sounds a bit cheesy, but who told him to have such a bad taste! Huaxing Company, which was independently spun off from the Oriental Research Institute, is mainly responsible for the R&D and manufacturing of mobile phones and mobile communication equipment.

※※※※※※※※※※※※※※※※※※※※

"Qianqian, do you think I should stay in the Oriental Research Institute, or transfer to the newly established Huaxing Technology?" Liu Wei sat on the sofa with a sad face, and asked his wife with some distress.

Now that Li Xuan has a plan in his mind, he naturally begins to take specific actions soon. This is the advantage of a private company. The Oriental Research Institute is not listed, so Li Xuan, the boss, does not need to be approved by the board of directors. Of course, before that, he must still communicate with the top management of the Eastern Group in advance. After all, the specific things still have to be done by the people below.

After Huaxing Technology decided to split, the R&D personnel who were in charge of the mobile communication group at the Orient Research Institute were faced with the choice of staying in the research institute or going to a newly established company.

As the first batch of fresh graduates recruited by the Oriental Group in China, Liu Wei joined the Oriental Research Institute after graduating from Tsinghua University and was arranged to work in the Deep Sea R&D Center. He majored in communication engineering at the university and joined the CDMA technology group from the very beginning, contributing a lot of achievements.

"I personally feel that Li Sheng obviously wants to make the Oriental Research Institute a relatively pure basic technology research and development institution. Although its benefits are very good in all aspects, it is only good! If you just want to study quietly technology, then staying in the research institute is the best choice!

If you have bigger ambitions, such as becoming the chief technology officer of a listed company, then you should jump out of the academy! People outside are going crazy, and the projects split by the Oriental Research Institute are all chickens that can lay golden eggs!

Like the previous Jiachuang technology company, after completing the first round of fundraising, the company's valuation has exceeded 1 billion US dollars. Those employees in Jiachuang who received equity incentives have at least doubled their net worth! "Fang Qianqian walked over with a plate of washed grapes~www.readwn.com~ and said with a smile.

"Then I'll go to Huaxing Technology. Its prospects are no worse than Jiachuang Technology!" Liu Wei thought for a while and finally made up his mind.

"What's wrong? I thought you would stay in the research institute! In fact, our family is not short of money, as long as you are happy!" Fang Qianqian's eyes flashed with surprise.

"As a man, you can't live without ambition! The consumption level in Hong Kong is so high, my father always has to work hard to earn money for milk powder for the baby in his womb!" Liu Wei gently touched his arms and snuggled into his arms. His wife's slightly bulging belly.

The husband and wife have a house and a car in Hong Kong, and there is a Chaojiang Chun chain restaurant with good profits in the Deep Sea Special Zone. But a man who is about to become a father has completely different responsibilities on himself. He hopes to give his children the best growth environment in the future. And these all need to be based on economic strength, so Liu Wei told himself to redouble his efforts to make money! (To be continued.)
