Li Sheng, a digital mobile phone that can realize basic functions such as making calls and receiving text messages, usually consists of five parts. The five parts are RF, baseband, power management, peripherals, and software.

Among them, the radio frequency part is responsible for the sending and receiving of information data, and its quality directly determines the call quality of the mobile phone. Motorola's Big Brother is able to beat other brands because its RF system is so good that it can maintain 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 power of the mobile phone battery is very limited, so the power management level directly determines the standby time of the mobile phone. If the standby time of the phone is too short, then even if its functions are excellent, the practical application value will be greatly reduced!

The core of these two parts is naturally RF chips and power supply chips. The M-88 digital mobile phone we launched this time uses 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, was accompanying Li Xuan to explain to him in detail.

Hong Kong Telecom has begun the trial operation of the CDMA digital mobile phone network, and Li Xuan naturally wants to carefully understand the development of the mobile communication business of 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 understand the situation.

On the other side of Tai Po Road, Sha Tin, Hong Kong, across the road from the Chinese University of Hong Kong, the research building of the Institute of Oriental Studies has been continuously expanded and increased to eight. In addition, the Hong Kong government surrounds the Hong Kong R&D center of the Oriental Institute. A large area around the area was circled and the Sha Tin Science and Technology Park was established.

To this end, the Hong Kong government has set up the management of the Hong Kong Science and Technology Park under the Secretary for Economic Affairs. It is responsible for the unified management and operation of the Sha Tin Science and Technology Park, as well as the Fotan Industrial Park, which has gradually become a high-tech electronics industry cluster. and an electronics industrial park in Tin Shui Wai.

In another time and space, Sha Tin is one of the largest satellite towns in Hong Kong outside of Hong Kong Island and Kowloon City. Its main role is to share the increasingly unbearable demographic pressure on the urban areas of Hong Kong and Kowloon. Even in the 21st century, Sha Tin is lackluster in all aspects except for a racecourse.

At this time, due to the emergence of the butterfly of the Eastern Group, Sha Tin seems to have begun to develop into a high-tech industrial cluster. Fotan Industrial Park has become Asia's most famous micro-business incubator and venture capital hub.

The original Ma Liu Shui, which is the location of CUHK, is also due to the settlement and expansion of the Hong Kong R&D Center of the Oriental Research Institute. It has become a scientific research mecca for many technicians throughout Asia. Many inventions have been born or are being born here that have influenced humanity as a whole. For example, ERM, the world's most widely used processor chip, came out here.

The world's first commercialized digital mobile phone, M-88, was also born in the Oriental Experimental Building next to Ma Liu Shui Tai Po Highway. The development process of the mobile phone is a huge system project, and the Eastern Bloc can proudly announce that it can support such an epoch-making project through continuous development.

For example, RF chips and power chips are provided by other Fairchild companies in charge of the analog semiconductor business of the Oriental Group. The system software of the mobile phone was developed by Dongfang System Software. The peripheral parts 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 most core part of the whole mobile phone, and the entire baseband system is composed of a central processing unit. A digital signal processor, channel encoders, modems, and interface modules.

On the M-88, the modules of the baseband part are still independent and dispersed, but we have already started the integrated research and development of the baseband chip. It is hoped that they can be integrated into a single SOC chip, thereby reducing the overall design difficulty of the mobile phone. Liu Yu pointed to the mobile phone motherboard that had just been unlocked, and introduced the role of each key chip to Li Xuan one by one.

The "M" in "M-88" stands for "Mobile". "88" is 1988. In the baseband system of the M-88 mobile phone, the CPU (central processing unit) uses the ERM architecture of the Eastern Group. In another time and space, the ARM architecture has relied on the mobile phone industry to turn over and become a processor architecture that can be as famous as Intel's X86 series.

And the DSP (Digital Processor) in the M-88 baseband system. It is also the technology that Li Xuan acquired from Texas Instruments at a considerable price. After the mobile phone industry begins to explode, Deyi Company estimates that even the intestines will regret it.

On the bright side, Li Xuan does not seem to have personally participated in the research and 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 design and layout of mobile phones, Li Xuan has made a good plan behind the scenes.

Listening to Liu Yu's introduction beside him, Li Xuan kept nodding. He pointed out that the general direction of research and development can only make the people below take fewer detours, but every scientific research achievement still requires researchers to spend countless ingenuity to explore. Hundreds or thousands of scientific research results come together to create a practical scientific and technological product.

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

Because the benefits of the Eastern Bloc are not just the M-88. With the transformation of mobile communications from the analog era to the digital age, the Eastern Group has taken the lead in the entire industry.

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

The Eastern Group also launched a layout in the field of communication equipment from the beginning. For example, the DS series digital program-controlled telephone exchange, which was produced in cooperation with China, has been continuously conquering the domestic market in recent years, and has almost completely squeezed other competitors out of the Chinese market.

The telecommunications equipment market is an area with a relatively high degree of monopoly. It is not easy for the Eastern Group to defeat the established European and American enterprises in the traditional telephone exchange and other markets. And in the emerging field of mobile communication devices. Everyone is back on the same page.

And the Eastern Bloc now has a huge advantage over the GSM technology being developed in Europe compared to the CDMA technology. Commercialization ahead of schedule. According to the intelligence that Eastern Commercial has spied on its channels in Europe, it will take at least one to two years for GSM to reach technical maturity.

If CDMA technology can show its excellent performance to the world before GSM comes out, it will undoubtedly gain a more favorable advantage 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 richer mobile phone functions. For example, our M-88 has features such as caller ID, voicemail, and text messages that Big Brother does not have!

In particular, text messages, i.e. sending and receiving text messages. The frequency of calls made by users can be greatly reduced. Those concise and non-essential exchanges can be communicated by texting, which greatly reduces the cost of call bills!" Liu Yu began to introduce the advantages of digital mobile phones.

Li Xuan, as a person who has come over, is naturally clear about this. SMS is one of the most important features in the 2G era, especially in developing countries like China, where the frequency of SMS usage is much higher than in Europe and the United States due to the high pricing of mobile phone call tariffs in the early days.

Previously, at Hong Kong Telecom, Li Xuan, like the company's president, Gu Xinping, emphasized the new technology of SMS. SMS can become an important breakthrough for operators to promote the low tariff of digital mobile phones, and a text message charges 0.1 Hong Kong dollars, which is much cheaper than making a phone call. 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. In the future, it has even surpassed the basic function of mobile phones to make calls. 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 spends time managing a multinational group with a total of tens of thousands of employees. It is also necessary to juggle between several women, focusing on the growth of the family and children. Naturally, there is very little time left to participate in scientific research in person. It's been a long time since he's been in the lab for days like he did with the original PR ERM structure. Now even the R&D center here in Shatin is going around occasionally.

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

This kind of large and comprehensive structure, if it were not for Li Xuan's rebirth golden finger and pointed out clear ideas to all aspects, it would inevitably lead to a decrease in efficiency. Everyone is a swarm of headless flies, and we don't know which areas are the priorities.

Therefore, after the phased results of the mobile communication project, 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 of the project team will still be retained in the Oriental Research Institute, such as CDMA (Code Division Multiple Access) communication technology, and will be cooperated with foreign countries in the form of patent authorization in the future.

As for the R&D at the application level, it is all spun off into a new subsidiary. Li Xuan has even thought of the name of the new company, which is called Huaxing Mobile Communication Technology Company. Later, there were two very famous communication equipment manufacturers in China, and Li Xuan simply took one of the two companies.

Huaxing, well, the name sounds a little earthy, but who called him to have such a bad taste! Huaxing Company, which was spun off from the Oriental Research Institute, is mainly responsible for the research and development and manufacturing of mobile phones and mobile communication equipment.

※※※※※※※※※※※※※※※※※※※※

"Qianqian, do you think I should continue to 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.

Since Li Xuan had a plan in mind, he naturally began to make specific moves soon. This is the benefit of a private company, the Oriental Research Institute is not listed, and Li Xuan, the boss, does not need to go through the approval of the board of directors or other institutions at all.

Of course, before this, he must still have to communicate with the top executives of the Eastern Group in advance, after all, the specific things still have to be done by the people below. There was nothing wrong with his thinking, so naturally there was no opposition within the group.

As one of the first batch of fresh graduates recruited by the Oriental Research Institute 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 university, and was placed in the CDMA technical group from the beginning and contributed a lot of achievements.
